• Windows Server 2012 Hyper-V very slow

  - by Matt Taylor

  I have been running several Hyper-V VMs on Windows Server 2008 R2 for the past couple of years and enjoying perfectly adequate performance for my testing/development/r&d environments. I'm a software developer so my hardware knowledge is basic however I built the rig using: •Gigabyte GA-X58A-UD3R Intel X58 (Socket 1366) DDR3 Motherboard •Intel Core i7 960 3.20GHz (Bloomfield) (Socket LGA1366) •24GB triple channel RAM The host OS is running on an OCZ SSD and all the VMs are running on a 2TB Marvell SATA3 RAID 0 array consisting of 2 Western Digital Caviar Black 7,200rpm drives. I have tested the speed of the 2TB drive and appear to be getting less than 3Mbs but it can adequately run a 4 VM farm including a DC, (SQL) database and IIS application servers. I recently upgraded the SSD on which the host runs to a 256GB OCZ Vertex 4 and took the opportunity to upgrade to Windows Server 2012 and installed the Hyper-V role. I tried importing one of my existing Windows Server 2008 R2 VMs (and converted it to .vhdx) plus I have tried creating a brand new Windows Server 2008 R2 VM but both are running extremely slowly and I can see nothing obvious using the host and guest Task Manager/Resource Monitor tools. In both cases the VM has 8GB RAM (fixed), 4 CPUs, fixed size HD (not expanding) and is using an external virtual network running on a separate NIC to the host. I have upgraded the BIOS to the latest available version and checked the virtualization settings. I have run out of "obvious" (to a developer) things to check/configure and my next option will be to re-install the host OS but before I do I would very much appreciate any advice from any experts out there. Thanks

• Which CPU for XEN - LAMP testbed - Budget

  - by deploymonkey

  Dear serverfault knowledgeables, im in a decision dilemma right now, which I can't resolve due to lack of hands on experience. I need to build a testbed for basically virtualizing a LAMP application (os'ses not yet decided) including server side calculations. I'll opt for XEN since it seems better supported by cloud hosters at the moment. The hardware is for a proof of concept for a startup doing saas and might be used for closed live alpha/beta later on. After testing, the testbed might be a) deployed as a colocated white box server b) used as workstation Single socket is enough. We want to have ECC memory for reliability, this excludes most of the consumer line at intel. If intel CPU, then threaded cpu (HT) is preferred have at least 16 gig ram If justified by price and reliability is not too bad, a high quality desktop MB instead of a server MB would be worth a try It came down to the opteron 6128 vs. the xeon 5620 for me after a lot of research, but I don't necessarily have to be right. Which CPU is preferrable, concerning TCO (MB price, power requirements 24/7...) , Opteron 6128 or Xeon 5620? Which one offers better performance in real world applications? (Do You have any other suggestions I probably overlooked?) Thank You for Your consideration

• What file transfer protocols can be used for PXE booting besides TFTP?

  - by Stefan Lasiewski

  According to ISC's dhcpd manpage: The filename statement filename "filename"; The filename statement can be used to specify the name of the initial boot file which is to be loaded by a client. The filename should be a filename recognizable to whatever file transfer protocol the client can be expected to use to load the file. My questions are: What file transfer protocols, besides tftp, are available to load the file (e.g. What protocols "can be expected to" load the file)? How can I tell? Can I see a list of these protocols? Does my choice of DHCP server influence which file transfer protocols are in use? Pretend I want to use dnsmasq instead of ISC's dhcpd Are these features dependent on the PXE which is in use (e.g. My Intel NICs use an Intel ROM)? I know that some PXE-variants, such as iPXE/gPXE/Etherboot, can also load files over HTTP. However, the PXE rom needs to be replaced with the iPXE image, either by chainloading or by burning the PXE rom onto the NIC. For example, the iPXE Howto "Using ISC dhcpd" says: ISC dhcpd is configured using the file /etc/dhcpd.conf. You can instruct iPXE to boot using the filename directive: filename "pxelinux.0"; or filename "http://boot.ipxe.org/demo/boot.php";

• SQL Server Installation: Is it 32 or 64 bit?

  - by CapBBeard

  Hi, Recently I was performing an OS upgrade on one of our DB servers, moving from Server 2003 to Server 2008. The DBMS is SQL Server 2005. While reinstalling SQL on the new Windows installation, I went to another of our DB servers to verify a couple of settings. Now, I always thought this second server was Server 2003 x64 + SQL 2005 x64 (from what I'd been told), but I now have my doubts about this. I now suspect that it is in fact only 32 bit SQL, however I'd like to verify this. Here's some details: The OS is definitely 64 bit. xp_msver shows Platform as NT INTEL X86 SELECT @@VERSION shows Microsoft SQL Server 2005 - 9.00.4035.00 (Intel X86)... However sqlservr.exe is not shown with '* 32' in taskmgr, does anyone know why this is the case, if it is in fact 32 bit as claimed? Despite this, it does seem to be running out of the x86 program files folder. If I do the same checks on a confirmed 64 bit installation, it does give back the expected 64 bit readings, which can only prove that this server in question is only running in 32 bit. Now, that being the case, the question arises about how much memory this '32 bit' install can use. Task manager reports about 3.5GB memory usage for sqlservr.exe (The server has 16GB physical). I suspect that AWE has not been configured at all, and therefore the server will be significantly under-utilised (remembering that the OS is 64 bit) if SQL is simply using a 32bit address space. Is this assumption correct? I feel the server should have SQL reinstalled as 64 bit in order to fully utilise the hardware platform, however it is currently heavily in production; this will be no easy task. I suspect we may just have to configure AWE correctly and let it be for the time being (Unless this is a bad idea?). I apologise that this question is a little vague/lost; I'm no SQL expert, just trying to get a handle on what's going on here.

• Advice on Computer Specs for overall development/general use machine

  - by Ender

  At the moment I am restricted to a laptop with 512MB of RAM, a 120GB HDD and a 1.5GHz Intel processor for all my development and general browsing needs, and as you can probably tell using it for anything modern is a painful experience. As a result I've decided to buy myself a new desktop computer, one that will stand the test of time and one that can be upgraded easily. Rather than build the machine myself I've decided to go through Dell as I've had good experiences with them when purchasing computers for my family. I've had my eye on this as it's got a good amount of RAM, has a decent-rated processor and isn't priced too badly. http://www1.euro.dell.com/uk/en/home/Desktops/inspiron-580/pd.aspx?refid=inspiron-580&s=dhs&cs=ukepp1&~oid=uk~en~20211~inspiron-580_d005827~~ Intel® Core™ i5 Processor 750 (2.66GHz, 8MB) Genuine Windows® 7 Home Premium 64bit - English Display Not Included ATI Radeon™ HD 5450 1GB DDR3 graphics 6144MB Dual Channel DDR3 [3x2048] Memory 1TB (7200rpm) SATA Hard Drive DVD +/- RW Drive (read/write CD & DVD) with DVD Burn software 1 year of coverage included with your PC McAfee® Security Centre - 15 Month Protection - English After the pain of using a slow laptop for all this time the main thing I want is speed. I may look to play a couple of basic games on it, nothing too powerful. Obviously I'll be doing some development on it too so it'll have to be able to handle the latest IDE's and Database tools like SQL Server pretty quickly. Finally, should I ever need to improve it I'd like to be able to add more RAM and change some of the parts. I wouldn't have thought this would be a problem but a few people I've spoken to have said that the amount of RAM the motherboard can handle isn't that great. Is this true? How long can I expect to be using this computer before it's too slow? Thanks in advance for the help.

• Graphics Artifacts/ Texture Flickering

  - by Cerin

  Hey I been having some problems with artifacts in games. Sometimes textures flicker. Artifacts of various shapes and sizes show up usually after a couple games of dota 2. I built my computer almost exactly one month ago and it has been doing this pretty much from the start except before the artifacts I believe just flashed on screen fast enough to where I couldn't tell what it was but I still noticed. In dota I've seen green triangular artifacts among other things. I've tried running Furmark for a while but even though it pushes the gpu much harder than dota 2, there are still no artifacts. It maxes in furmark at about 60C and running every game I've tried on it at 40C. CPU and system temp don't usually get higher than 40C either. These are my system specs: Gigabyte Z68 Intel Motherboard 16 GB Gskill Ripjaws SDRAM DDR3 Sapphire Radeon HD 7770 GHz edition Intel Core i5-2500k (with built in gpu) Corsair 750 Watt PSU windows 7-64 bit I have the latest drivers for everything. What should I do about this? Try to RMA my graphics card? Are there other things that could be causing this?

• Building My First Computer And Suprise It Isn't Working

  - by BobbShots

  I've had many years of experience working on and around computers, but this was my first foray into building one completely from scratch. So far that foray has been a disaster. My rig is completely assembled, and on its maiden power-up plus many power cycles I noticed three things: There were a few beeps from the BIOS POST upon powering up the first time, but I wasn't paying attention completely to the sequence. However, every time after that there are 0 POST beeps, even after taking off all hardware except the CPU and MB. There was no video being sent to the monitor. I run a HDMI cable from my video card to the monitor. The video card was LOUD. My card is a Sapphire Radeon HD 5870 which is known for not only being a powerhouse, but being pretty quiet. A few times during my power cycles it ran a lot quieter, but most of the time it was just super loud. Can anyone provide help for any of these issues? My MB, CPU, and Video Card are: MB: ASUS P6X58D Premium LGA 1366 Intel X58 SATA 6Gb/s USB 3.0 ATX Intel Motherboard CPU: i7 920 Video Card: Sapphire Radeon HD 5870

• Processes spawned by taskset not respecting environment variables

  - by jonesy16

  I've run into an issue where an intel compiler generated program that I'm running with taskset has been putting its temporary files into the working directory instead of /tmp (defined by environment variable TMPDIR). If run by itself, it works correctly. If run with taskset (e.g. taskset -c 0 <program> Then it seems to completely ignore the TMPDIR environment variable. I then verified this by writing a quick bash script as follows: contents of test.sh: #!/bin/bash echo $TMPDIR When run by itself: $ export TMPDIR=/tmp $ test.sh /tmp When run through taskset: $ export TMPDIR=/tmp $ taskset -c 1 test.sh "" Another test. If I export the TMPDIR variable inside of my script and then use taskset to spawn a new process, it doesn't know about that variable: #!/bin/bash export TMPDIR=/tmp taskset -c 1 sh -c export When run, the list of exported variables does not include TMPDIR. It works correctly with any other exported environment variable. If i diff the output of: export and taskset -c 1 bash -c export Then I see that there are 4 changes. The taskset spawned export doesn't have LD_LIBRARY_PATH, NLSPATH (intel compiler variable), SHLVL is 3 instead of 1, and TMPDIR is missing. Can anyone tell me why?

• Doesn't VirtualBox 4.0 support drag-drop file copy yet?

  - by Benjamin

  Version 4.0.0 will be new major release. The following major new features were added: -New settings/disk file layout for VM portability; see the manual for more information. -Open Virtualization Format Archive (OVA) support; see the manual for more information. -VMM: support more than 1.5/2 GB guest RAM on 32-bit hosts -Language bindings: uniform Java bindings for both local (COM/XPCOM) and remote (SOAP) -invocation APIs -Chipset: added support for the Intel ICH9 chipset with 3 PCI buses, PCI express and -Message Signaled Interrupts (MSI) -Audio: Intel HD Audio is now available as guest hardware, for better support with modern -guest operating systems (e.g. 64-bit Windows; bug #2785). -GUI: redesigned user interface with guest window preview -GUI: new display mode with downscaled guest display -Resource control: added support for limiting a VM's CPU time and IO bandwidth. -Storage: support asynchronous I/O for iSCSI, VMDK, VHD and Parallels images -Storage: support for resizing VDI and VHD images -Windows Additions: support for automatically updating the Guest Additions (requires -installed Windows Guest Additions 4.0 or later) -Guest Additions: support for copying files into the guest file system What does the last line mean? I thought this is a drag-drop file copy feature like VMWare. I tried that. But I couldn't copy by drag-drop, ctrl-c ctrl-v either. Edit: I mean VBox 4.0 beta, not 3.x The release note is here. Download link is here.

• Can I format a usb stick on windows xp, in HFS+ format, and make the usb stick mac os x bootable?

  - by user717236

  My Intel Mac OS X computer is corrupt and I feel, at this point, I need to perform a fresh install of the OS. It consistently and automatically logs out, right after I log in. I tried logging in as the root. I tried safe boot and it wouldn't load. Anyway, the point is I want put the Mac OS X installer on a USB thumb drive and have it boot up on the Intel Mac OS X computer. Unfortunately, the computer is inaccessible, as I mentioned above. So, I have a Windows XP machine that I'm using and attempting to create a bootable USB thumb drive that's compatible with Mac OS X. I have tried transmac, macdrive, and paradox for windows -- all of which proved unable to format the usb stick in HFS+. How do I know this? Well, even though the Transmac reports that's been formatted to HFS+, Computer Management in Windows says otherwise: I even put the installer on the usb drive, after transmac reportedly formatted it properly, and the mac os x computer didn't even recognize that a USB thumb drive was inserted, via pressing the option key at boot-up time. I'm not sure what the problem is and how to actually format the drive. Can anybody offer any help? I would appreciate it. Thank you.

• Gigabyte H55N-USB3: No video on HDMI

  - by newt

  I built a new PC with a Gigabyte H55N-USB3 / Intel Core i5 650. With a monitor plugged in the DVI port, everything works fine. I installed Windows 7 32-bit and enabled remote desktop connection. After that, I unplugged the monitor, plugged it into network and installed everything else (drivers, programs, etc) via RDP. However, when I try to use the HDMI port on my TV nothing appears. Neither during the boot, neither after Windows starts. The TV says there's "no signal" (if I remove the cable the message changes to "check cable"). The cable is new, and it is working fine with my home theater on same TV (by the way, it is the cable which came bundled with the home theater). Video driver is the latest from Intel site. Anyway, this shouldn't be the problem since there is no image during the boot. Any ideas or tips would be welcome. I'm googling around but found nothing useful, yet.

• High-performance Academic Server [closed]

  - by PHPsmith

  Suppose I want to build a server for the university's academic interests. The server is dedicated only to a site, where users (students and lecturers) just view and fill the academic data. But at a time (e.g. once a semester), about 12,000 students will access the site simultaneously. Due to limitation of resources, I have to build the server using free software (except for the operating system Windows 7, the university has been prepared). The hardware is also limited to the usual 4-core computers (eg, Ivy Bridge Intel Core i7-3770) with approximately 16GB of memory (DDR3 1600 MHz), equipped with an RJ-45 port (Intel 82 579 Gigabit Ethernet). With all these limitations, I have to choose the software (web server, database, etc) are appropriate for this purpose is achieved. I decided to create a site in PHP. Please help me by answering the following questions based on your expertise. (my prime candidate software to consider after googling) Web server which is faster & stable & secure, when implemented and optimized for PHP? And why? (nginx) PHP accelerator which is faster & stable & compatible with the selected web server? And why? (APC with Zend Optimizer+) Database which is faster & stable & secure, when implemented and optimized for selected web server and selected PHP accelerator? (MySQL) Are there any errors that have been or will be happening from my condition is? If there is, please enlighten me? Is there anything else I need to know in order to achieve this goal? If there is, please enlighten me? I understand that the performance also depends on the implementation of source-code program, so I assume it will create a site with the best efficiency (e.g. using AJAX).

• xen + debian network after upgrade squeeze to wheeze

  I've got a Debian + Xen server. After a system upgrade to the stable version the network doesn't come up after boot. Every time after reboot I need to bring it up manually.

• In Windows 7 power management, is it possible to set different sleep settings for different SATA disks?

  - by Ben Voigt

  I'm having an issue with Windows 7 either freezing up or generating a BSOD coming out of sleep. I suspect that it is related to my boot/OS drive, an OCZ Vertex SE SSD, because numerous other Vertex users have reported sleep problems. Notably, if I put the computer to sleep, it almost always wakes correctly. If it goes to sleep after a timeout, it almost always BSODs. I disabled timed sleep and now it freezes when left unattended. My next step is to disable "Put hard disks to sleep after X minutes", but I'd like to change this setting only for the SSD and not for the rotating data disks, which I would like to spin down normally. Does anyone know a place to configure sleep on a per-disk basis? I don't need to set different timeouts on different disks (although that would be nice), simply setting "this disk sleeps" and "sleep is disabled for this disk" would be great. Additional system information: Windows 7 Ultimate x64, Core i5 - P55 chipset, Intel RST drivers are installed. One SSD, two rotating HDD, and a DVD-RW drive are all connected to the Intel SATA ports. I could potentially move some of these to my motherboard's other SATA controller if that would help.

• lenovo x1 carbon windows 8 frequent wifi disconnect issue

  - by hIpPy

  I'm having frequent wifi disconnects on my Lenovo X1 Carbon Touch laptop. I got this laptop 2 months back and it has been happening ever since about 3-5 times a day and 10 times a week on average. I've Frontier Fios internet. Power connected or not does not matter. Once I get disconnected, I try below to connect again in that order: turn Airplane mode on and off, troubleshoot network problems windows troubleshooter), restart the laptop I'd find that the WiFi adapter would get disabled and sometimes windows troubleshooting would help but more than often I'd end up restarting the laptop. A week back, I upgraded my wifi network adapter drivers (now Intel, version 15.5.6.48, 10/3/2012). I still get disconnected frequently but turning Airplane mode on and off gets me connected again. So the driver update did help. Windows 8 is updated. None of the other devices (nexus, iphone phones, nexus7, ipad tablets) would have wifi issues when my laptop would get disconnected. config: Intel(R) Centrino(R) Advanced-N 6205 (WiFi network adapter) Microsoft Windows 8 Pro Microsoft Windows [Version 6.2.9200] x64-based PC LENOVO System Model: 3443CTO X1 Carbon Touch I recently noticed this log message When I got disconnected in event viewer: Your computer was not assigned an address from the network (by the DHCP Server) for the Network Card with network address 0x[XXXXXXXXXXXX].

• Out of memory errors but not actually out of memory...

  - by commradepolski

  So, myself and my fellow support techs have been fighting with this issue and we still dont know what the problem is. Lets start off with the system specs: Windows XP 32 bit Corporate (SP2 and SP3) Intel D975XBX2 Mobo 4gb of ram Intel Core 2 Quad Q6600 ATI Radeon HD 3600 - 512mb After a few hours of working on the machine, the end user will begin to see the following symptoms: Out of memory messages Title bars and menus dont draw in properly Problems accessing network resources Problems opening up documents such as MSWord and MSPowerpoint and text files Problems opening up explorer windows General instability We have looked at task manager while this issue was occurring, and all indicators, like PF usage, threads, handles, etc. are normal. We have been having trouble pinpointing the root cause of this issue. It is also not situated with one user, it affects 8-10. So far we have tried: Resetting CMOS (Waiting to see results) Replacing video card (didnt help) Windows updates (didnt help) Updating network drivers (didnt help) Switching user from 1gbps to 100mbps network connection (awaiting results) Swapping the affected user's hardware (waiting for results) Increasing desktop heap size (helped for a bit but then the issue became more frequent) Applying the /3 switch to XP (didnt help) Increasing and decreasing and setting PF to system managed state (didnt help) We did have a power outage at the office a couple weeks ago, and all these issues became more frequent. Prior to the power outage it may take a week or so for the users to experience the issues but since the power outage it takes 3-4 hours or less. We havent had reports of the above issues causing BSODs, although that would be easier to diagnose :). Any help is greatly appreciated.

• Linux iptables / conntrack performance issue

  - by tim

  I have a test-setup in the lab with 4 machines: 2 old P4 machines (t1, t2) 1 Xeon 5420 DP 2.5 GHz 8 GB RAM (t3) Intel e1000 1 Xeon 5420 DP 2.5 GHz 8 GB RAM (t4) Intel e1000 to test linux firewall performance since we got bitten by a number of syn-flood attacks in the last months. All machines run Ubuntu 12.04 64bit. t1, t2, t3 are interconnected through an 1GB/s switch, t4 is connected to t3 via an extra interface. So t3 simulates the firewall, t4 is the target, t1,t2 play the attackers generating a packetstorm thorugh (192.168.4.199 is t4): hping3 -I eth1 --rand-source --syn --flood 192.168.4.199 -p 80 t4 drops all incoming packets to avoid confusion with gateways, performance issues of t4 etc. I watch the packet stats in iptraf. I have configured the firewall (t3) as follows: stock 3.2.0-31-generic #50-Ubuntu SMP kernel rhash_entries=33554432 as kernel parameter sysctl as follows: net.ipv4.ip_forward = 1 net.ipv4.route.gc_elasticity = 2 net.ipv4.route.gc_timeout = 1 net.ipv4.route.gc_interval = 5 net.ipv4.route.gc_min_interval_ms = 500 net.ipv4.route.gc_thresh = 2000000 net.ipv4.route.max_size = 20000000 (I have tweaked a lot to keep t3 running when t1+t2 are sending as many packets as possible). The result of this efforts are somewhat odd: t1+t2 manage to send each about 200k packets/s. t4 in the best case sees aroung 200k in total so half of the packets are lost. t3 is nearly unusable on console though packets are flowing through it (high numbers of soft-irqs) the route cache garbage collector is no way near to being predictable and in the default setting overwhelmed by very few packets/s (<50k packets/s) activating stateful iptables rules makes the packet rate arriving on t4 drop to around 100k packets/s, efectively losing more than 75% of the packets And this - here is my main concern - with two old P4 machines sending as many packets as they can - which means nearly everyone on the net should be capable of this. So here goes my question: Did I overlook some importand point in the config or in my test setup? Are there any alternatives for building firewall system especially on smp systems?

• Windows 7 does not detect my new hard drive?

  - by jasondavis

  I just built a really nice new PC. Some specs... Intel i7-930 CPU ASRock Extreme X58 motherboard with sata 3 and USB 3.0 12gb of G-Skill DDR3 RAM 80gb Intel G2 Solid state drive for Windows 7 and other programs to run on Windows 7 Pro 64bit OS 2 1gb grapghic cards for 4 monitor support Thats the main components. Well today my new 1tb western digital hard drive came which I plan to use for data to preserve the life of my SSD (hopefully). I hooked up it's sata power input and then hooked up it's sata data cable to a sata 2 port on my motherboard, I boot windows 7 and go into my computer and the drive is not showing up with my other drives. I then re-boot again and check again, no luck. I then shut down the PC and open the case back up, I then check my connections and they all look good. I then boot up and I can see the new HD is on and spinning. I then go into my BIOS settings to see if it registers there and it DOES! It shows I have a WD 1tb hard drvie on sata 2 port 6. So I am at a loss of why it is not showing up as an option in windows? Windows acts as if the drive is not there. Please help

  I have a computer with an external IP(192.168.223.220) and also an internal address (10.1.1.20) in order to connect to some servers that don't have external addresses only 10.1.1.xx . in order to connect to these servers from other machines I used the following command "route ADD 10.1.1.0 MASK 255.255.255.0 192.168.223.220" and than I was able to connect to the servers using there 10.1.1.xx address. The problem is that the hard disk of main server(192.168.223.220) died and was replaced and after the that I am not able to connect to the servers as before, the route command succeeds and I can ping 10.1.1.20 but not the other servers. Thanks I am using Windows XP and the print outs are D:\AurosHome\Scriptsipconfig /all Windows IP Configuration Host Name . . . . . . . . . . . . : N100-master Primary Dns Suffix . . . . . . . : Node Type . . . . . . . . . . . . : Unknown IP Routing Enabled. . . . . . . . : No WINS Proxy Enabled. . . . . . . . : No Ethernet adapter Local Area Connection 3: Connection-specific DNS Suffix . : Description . . . . . . . . . . . : Intel(R) PRO/1000 EB Network Connection with I/O Acceleration #2 Physical Address. . . . . . . . . : 00-30-48-34-BA-B9 Dhcp Enabled. . . . . . . . . . . : No IP Address. . . . . . . . . . . . : 192.168.225.180 Subnet Mask . . . . . . . . . . . : 255.255.255.0 Default Gateway . . . . . . . . . : 192.168.225.254 DNS Servers . . . . . . . . . . . : 192.168.225.2 Ethernet adapter Local Area Connection: Connection-specific DNS Suffix . : Description . . . . . . . . . . . : Intel(R) PRO/1000 EB Network Connection with I/O Acceleration Physical Address. . . . . . . . . : 00-30-48-34-BA-B8 Dhcp Enabled. . . . . . . . . . . : No IP Address. . . . . . . . . . . . : 10.1.1.20 Subnet Mask . . . . . . . . . . . : 255.255.255.0 Default Gateway . . . . . . . . . : Ethernet adapter Local Area Connection 2: Media State . . . . . . . . . . . : Media disconnected Description . . . . . . . . . . . : Mellanox IPoIB Adapter Physical Address. . . . . . . . . : 00-02-C9-25-34-0D D:\AurosHome\Scriptsroute print Interface List 0x1 ...........................

• Sound doesn't work anymore after replacing RAM

  Hello, today, I replaced one old RAM module with two newer, bigger ones, but now, the sound doesn't seem to work anymore. Already ran alsaconf and it didn't help. Output of lspci for the audio device: 00:07.0 Audio device: nVidia Corporation MCP67 High Definition Audio (rev a1) Subsystem: Giga-byte Technology Device a002 Control: I/O- Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop- ParErr- Stepping- SERR- FastB2B- DisINTx- Status: Cap+ 66MHz+ UDF- FastB2B+ ParErr- DEVSEL=fast >TAbort- <TAbort- <MAbort- >SERR- <PERR- INTx- Latency: 0 (500ns min, 1250ns max) Interrupt: pin A routed to IRQ 21 Region 0: Memory at f5100000 (32-bit, non-prefetchable) [size=16K] Capabilities: [44] Power Management version 2 Flags: PMEClk- DSI- D1- D2- AuxCurrent=0mA PME(D0-,D1-,D2-,D3hot+,D3cold+) Status: D0 PME-Enable- DSel=0 DScale=0 PME- Capabilities: [50] Message Signalled Interrupts: Mask+ 64bit+ Queue=0/0 Enable- Address: 0000000000000000 Data: 0000 Masking: 00000000 Pending: 00000000 Capabilities: [6c] HyperTransport: MSI Mapping Enable+ Fixed+ Kernel driver in use: HDA Intel Kernel modules: snd-hda-intel The audio device is onboard and has six configurable outputs, two or so are also capable of being an input (if I remember it correctly), but I don't know how to control it under linux. Does somebody know how/whether replacing the RAM could be related to my problem and/or how to fix it?

• Can I have a single solid state drive and a RAID array on the same machine? [closed]

  - by jaminto

  Hi- To summarize, i'm looking to use a single solid state drive as my primary drive, and two conventional sata drives in a RAID 1 configuration for data. I am trying to install 64-bit Windows 7 onto this configuration. Is this possible? Here are the details: I built a desktop that has been running 64-bit Vista on two 500Gb in a RAID 1 array for a few years. I just purchased an Intel X25-M 80Gb Sata Solid-State Drive, and was planning on using this a my primary drive, and keeping the RAID 1 array as my data drive. I added the SSD drive and in the RAID setup, configured it as a RAID 0 array of only one disk. Then, I tried to do a clean install of windows 7 64-bit, but got stuck in the "Missing driver for CD/DVD drive" black hole of selecting driver files and Windows telling me that i don't have the appropriate driver for my hardware. The missing hardware is NOT a CD/DVD drive, since i'm installing off of my only CD/DVD drive. Plus at one point i was able to point it at a driver for my raid controller, and then my hard drives magically showed up as browsable sources for finding drivers for some other unnamed device that setup couldn't recognize. After a few hours of trying drivers (this was a very slow process) i decided to reboot and look at the BIOS settings. I'm using an ASUS M2A-VM motherboard which has an ATI SB600 RAID controller on board. I switched the "On board SATA Type" setting from "SATA" to "AHCI" thinking that since AHCI is an Intel thing, this would help. Unfortunately, this abandoned my RAID configuration, and my previously mirrored drives are showing up as separate drives when i boot into my current windows installation. Am i trying to do the impossible here? Should i just buy a separate SATA/RAID PCI card and plug the SSD into that? Any help would be greatly appreciated.

• Can I install windows on an SSD and access data from my old windows HDD?

  - by nzifnab

  I purchased new computer components, switching my hardware from AMD and Radeon to Intel and Nvidia. I kept components from my old computer like the powersupply and two HDDs. Everything appeared to install correctly and the system booted into the BIOS just fine (after a brief snafu with the CPU fan). My goal was to use the two harddrives and just be able to turn on the computer and load up my old windows install with all the files, programs, and documents. I expected to have to call Microsoft to re-register the windows install for the new hardware (since I had to do that last time I upgraded w/ the same windows version). When the computer attempts to boot into windows it briefly flashes a bluescreen and then restarts. System recovery gives a message something like "BadDriver Failover" something something. I assume this is because it's trying to use amd drivers for an intel chipset (or something...?) and I've been as-yet unsuccessful in getting it to boot into my old windows partition. SO! I decided eff it, maybe I'll go visit my nearest Micro Center and buy a 200 GB SSD, install windows onto that, and then... be able to access just the contents of both of my other harddrives? I don't intend on running any of the programs but there were some saved files I would like to salvage from the 500 GB harddrive, The 1.5 TB harddrive only had files on it, no OS or applications so I'd also expect to still be able to access it. Is this possible? Can I install the SSD and only format/install windows onto it and still access the contents from my two transferred-over drives?

• HP DL380 G3 2U For Basic Web Server in 2012

  - by ryandlf

  I have an opportunity to pick up a used HP DL380 G3 2U for $100. I'm looking for a basic entry level web server that I can host a small - medium size website on and more or less learn the ins and outs of running my own web server before I bite the bullet and spend a couple grand on a server. The specs are: Dual (2) Intel Xeon 2.4GHz 400MHz 512KB Cache 4GB PC2100 ECC Registered Memory 6 x 72GB 10K U320 SCSI Hard Drives Smart Array 5i RAID Controller Redundant Power Supplies DVD/Floppy, Dual Intel GB NIC's, USB Or would I be better off spending a couple hundred bucks on something like: this new HP Seems like the only major difference is SATA and a bit of storage, but I will likely be implementing a separate storage system of some sort anyways. I guess it also wouldn't hurt to mention that I plan on running a linux server distro, so would the hardware be likely to support linux with a system that is 4 generations old? I don't mind spending a couple hundred extra dollars if its a better solution, but as mentioned previously I am simple looking for a server to learn on and probably use for a year or so while I put together a small - medium size website.

• Windows Server 2008 R2 grinds to a screeching halt during file copy operations

  - by skolima

  When my Windows Server 2008 R2 machine is performing any large disk operations (copying 10GB files from one drive to another, copying similar file over network, merging HyperV snapshots, compressing large files), performance of the whole machine slows down terribly, everything becomes unresponsive. This is noticeable in any situation when the disk access is large enough not to fit in the cache. Are there any settings available for tuning this behaviour? I can accept slower file transfer if this would give me more responsiveness. System details: Dell Optiflex 960, Core 2 Quad Q9650, 8GB RAM, 2 SATA drives - 320GB (ST3320418AS) and 1TB (ST31000528AS), NCQ active on both, Intel 82564LM-3 Gigabit Ethernet, ATI HD 3450 graphics, Intel ICH10 bridge. We have multiple machines like this, every one is exhibiting the same behaviour. I though this was overkill for a workstation, apparently I was mistaken. Update: I guess I shouldn't have mentioned the HyperV at all. The above configuration is a standard workstation setup at the company I work for, this is not a server of any kind. I have at most 3 virtual machines working, and usually I'm the only person accessing them. Never the less, the slowdown occurs even when no VMs are running. On a Linux machine I'd simply ionice the copy process and I could forget about it, is there any way to manage IO priorities on Windows?

• 5 year old server upgrade

  - by rizzo0917

  I am looking to upgrade a server for a web app. Currently the application is running very sluggish. We've made some adjustments to mysql (that's another issue in itself) and made some adjustments so that heaviest quires get run on a copy of the database on another server was have as a backup, however this will not last that much longer and we are looking to upgrade. Currently the servers CPUs are (4) Intel(R) XEON(TM) CPU 2.00GHz, with 1 gig of ram. The database is 442.5 MiB, with about 1,743,808 records. There are two parts of the program, the one, side a, inserts and updates most of the data. Side b, reads the data and does some minor updates. Currently our biggest day for side a are 800 users (of 40,000 users all year) imputing the system. And our Side b is currently unknown, however we have a total of 1000 clients. The system is most likely going to cap out at 5000 side b clients, with about a year 300,000 side a users. The current database is 5 years old, so we can most likely expect the database to grow pretty rapidly, possibly double each year (which we can most likely archive older records if it comes to that). So with that being said, should we get a server for each side of the app, side a being the master, side b being the slave, any updates made on side b are router to side a. So the question is should i get 2 of these or 1. 2 x Intel Nehalem Xeon E5520 2.26Ghz (8 Cores) 12GB DDRIII Memory 500GB SATAII HDD 100Mbps Port Speed And Naturally I would need to have a redundant backup so it could potentially be 4 of them.
