• Install Ubuntu on a new netbook?

  - by torbengb

  I'm planning to buy a netbook, and I am considering to install Ubuntu on it. It would mainly be used by my wife at home for web browsing and email at home (lightweight is important, hence a netbook!), and we'd occasionally bring it along on travels (mostly as digital photo dropzone). I want to use Ubuntu instead of Windows because I'm sick of all the Windows hassle and updates. I'm not concerned about Windows applications; I'd switch to native alternatives as far as possible because really only Firefox and something like Picasa are needed. I'm considering an ASUS Eee PC 1001P or an MSI Wind U100 or an Point of View Mobii II (click the links for specs; nevermind that the rest is German). I'm not in the USA. Whatever I buy will most likely have Windows 7 on it but no optical drive. I would also buy a large-ish USB stick but not an external optical drive. Should I (and can I) install Ubuntu alongside Windows 7, or remove Windows? If I remove Windows first, how would I be able to reinstall it if I change my mind? Can I make a backup? Is a recovery CD usually provided? Should I choose the regular Ubuntu, or the Ubuntu Netbook Remix (UNR)? Does UNR allow me to install additional applications just as easily? Note: I'm asking about Ubuntu vs. Windows; let's skip the hardware discussion for now. Edit: I'm assuming that Windows is already installed; if it isn't then I would only install Ubuntu and this question is irrelevant.

• Move database from SQL Server 2012 to 2008

  - by Rich

  I have a database on a SQL Sever 2012 instance which I would like to copy to a 2008 server. The 2008 server cannot restore backups created by a 2012 server (I have tried). I cannot find any options in 2012 to create a 2008 compatible backup. Am I missing something? Is there an easy way to export the schema and data to a version-agnostic format which I can then import into 2008? The database does not use any 2012 specific features. It contains tables, data and stored procedures. Here is what I have tried so far: I tried "tasks" - "generate scripts" on the 2012 server, and I was able to generate the schema (including stored procedures) as a sql script. This didn't include any of the data, though. After creating that schema on my 2008 machine, I was able to open the "Export Data" wizard on the 2012 machine, and after configuring the 2012 as source machine and the 2008 as target machine, I was presented with a list of tables which I could copy. I selected all my tables (300+), and clicked through the wizard. Unfortunately it spends ages generating its scripts, then fails with errors like "Failure inserting into the read-only column 'FOO_ID'". I also tried the "Copy Database Wizard", which claimed to be able to copy "from 2000 or later to 2005 or later". It has two modes: 1) "detach and attach", which failed with error: Message: Index was outside the bounds of the array. StackTrace: at Microsoft.SqlServer.Management.Smo.PropertyBag.SetValue(Int32 index, Object value) ... at Microsoft.SqlServer.Management.Smo.DataFile.get_FileName() 2) SQL Management Object Method which failed with error "Cannot read property IsFileStream.This property is not available on SQL Server 7.0."

• Hyper V Server 2012 Remote Management Using Workgroup

  - by Chris Kolenko

  I'm trying to remotely manage Hyper V server 2012 from a windows 8 pc, both client and server are on a workgroup. I've spent about 3-4 hours trying to get this working with no luck so far trying the following: Creating a new administrator on the server with the same details as the client ie. username / password. Add an entry into my hosts file to point to the remote ip by server name. Tried using HVRemote. Disabled both firewalls. The error that I'm getting is RPC Service Unavailable. How can I accomplish what I'm trying to do? Update Some of the operations on the Hyper-V Manager work. IE. Virtual Switch Works. I can open the New VM Wizard. I run into an error when creating a new Virtual Hard Disk tho. I've tried creating a VM without a hard disk, which works. Using the new hard disk wizard does not work either. I still can not see any Virtual Machines. RPC server unavailable. Unable to establish communication between 'ServerName' and 'ClientName'

• 3d Studio Max and 2+CPUs - Core limit ?

  - by FreekOne

  Hi guys, I am scouting for parts to put in a new machine, and in the process, while looking at different benchmarks I stumbled upon this benchmark and it got me a bit worried. Quote form it: Noticably absent from this review is an old-time favorite, 3ds Max. I did attempt to run our custom 3ds Max benchmark on both the 2009 and 2010 versions of the software, but the application would simply not load on the Westmere box with hyper-threading enabled. Evidently Autodesk didn't plan far enough ahead to write their software for more than 16 threads. Once there is an update that addresses this issue, I will happily add 3ds Max back into the benchmarking mix. Since I was looking at dual hexa-core Xeons (x5650), that would put my future machine at 24 logical cores which (duh) is well over 16 cores and since I'm mostly building this for 3DS Max work, you can see how this would seriously spoil my plans. I tried looking for additional information on this potential issue, but the above article seems to be the only one who mentions it. Could anyone who has access to a 16 core machine or an in-depth knowledge about 3DS Max please confirm this ? Any help would be much appreciated !

• IPCop Packet Mangling

  - by Zenham

  I've found myself in a pickle replacing an old firewall for a client this afternoon. I'm configuring their new IPCop firewall (1.4.21), Zerina OpenVPN addon is installed. What I need to do: There are three network interfaces, currently set up as red (WAN), green (LAN, 192.168.20.0/24) and orange (remote network 10.1.20.0/24). The orange interface is a direct fiber link to another organization. Simple description: Traffic and networks appear to be properly configured at this point, but I have many (150+) specific IPs on the LAN which, when accessing the resources on the 10.1.20.x network, need to be mangled to appear to be coming from the 10.1.20.0/24 network (and return traffic properly delivered). The routing on the far side was configured earlier and should be fine, but I need to redirect any packets coming across destined for those IPs to end up at their proper destination. The addressing is fixed and predictable (ie. 192.168.20.125 - 10.1.20.125). I need to insert whatever rules I have into the IPCop ruleset through /etc/rc.local I know, I'm just not sure about how I should structure this. There's CUSTOMOUTPUT and CUSTOMINPUT targets, both which currently just consist of the single rule redirecting packets to the OVPNOUTPUT/OVPNINPUT targets, so I'm guessing I should insert a rule matching outbound packets destined for the 10.1.20.x network and redirecting to a new target (maybe called TO-ORANGE) and a rule at the top of CUSTOMINPUT which redirects to a FROM-ORANGE target. Under those targets, I would have rules which do the IP matching and mangling. Am I approaching this right? If so, I'm not very familiar with mangle, and would appreciate seeing examples of how to write that source-IP rewrite. If not, how would you suggest doing this? TIA! edit: I notice additionally that the nat table has CUSTOMPREROUTING and CUSTOMPOSTROUTING targets, I guess I could alternatively post the rules in there....

• How to get decent WiFi despite a virtual Faraday cage

  - by MT_Head

  One of my clients is the local branch of an international airline. They have a small office in the secured area behind the ticket counters, and timeshare space at the ticket counter. I need to add a ticket printer out front, which I cannot (for contract/liability reasons) attach to the shared computer at the counter; the only workable solution seems to be to put the printer and its attached computer on a cart and connect to the office's network via WiFi. So far, no problem - right? Well, the terminal has been getting a facelift, which - among other things - includes decorative stainless-steel panels along the wall behind the ticket counters. This paneling acts as a seriously effective barrier to WiFi! The office's WiFi router - a brand-new D-Link DIR-815, dual-band 802.11n - is just on the other side of the pictured wall, and twenty feet or so to the right. And yet the only way I can connect AT ALL on this side of the wall is to stick the USB adapter (on the end of an extension cable) right into the crack between panels... and even then I can only see the 5GHz network, and that very weakly. Has anyone else had experience with this sort of misguided interior decoration? Any ideas on how I can improve reception on the other side of the barrier? (Needless to say, physical modifications of the environment - tempting though they might be - are strictly no-go.)

• Passenger error: No such file or directory - config/environment.rb

  - by JJD

  I installed Redmine on MacOSX Server 10.6.8 according to this installation description. So far everything works fine: When I start webrick the server serves the Redmine pages. The gems and redmine are installed under the user "redmine". After that I aimed configuring apache2 with passenger as described here. As suggested by the description I also installed the passenger-pane which stores its virtual host configuration files in /private/etc/apache2/passenger_pane_vhosts. This is what I came up with after a lot of manual try and error. At least, now I can reach a passenger error page. // redmine.vhost.conf <VirtualHost *:80> ServerName host ServerAlias localhost DocumentRoot "/Users/redmine/Sites/redmine" # RackEnv production # RackBaseURI / RailsEnv production RailsBaseURI / # PassengerUser www-data # PassengerGroup www-data <Directory "/Users/redmine/Sites/redmine"> Order allow,deny Allow from all </Directory> </VirtualHost> However, the passenger module still runs into the following errors. Error message: No such file or directory - config/environment.rb The /var/log/apache2/error_log of the web server stated the following. [warn] NameVirtualHost *:80 has no VirtualHosts [notice] Apache/2.2.21 (Unix) Phusion_Passenger/3.0.12 configured -- resuming normal operations [ pid=21824 thr=2151905620 file=utils.rb:176 time=2012-06-01 18:22:07.126 ]: *** Exception Errno::ENOENT in PhusionPassenger::ClassicRails::ApplicationSpawner (No such file or directory - config/environment.rb) (process 21824, thread #<Thread:0x0000010086f2a8>): I experimented with the user switch functionality of passenger as described in the documentation - as you can tell from my configuration file. Though, I was not successful.

• Performance of file operations on thousands of files on NTFS vs HFS, ext3, others

  - by peterjmag

  [Crossposted from my Ask HN post. Feel free to close it if the question's too broad for superuser.] This is something I've been curious about for years, but I've never found any good discussions on the topic. Of course, my Google-fu might just be failing me... I often deal with projects involving thousands of relatively small files. This means that I'm frequently performing operations on all of those files or a large subset of them—copying the project folder elsewhere, deleting a bunch of temporary files, etc. Of all the machines I've worked on over the years, I've noticed that NTFS handles these tasks consistently slower than HFS on a Mac or ext3/ext4 on a Linux box. However, as far as I can tell, the raw throughput isn't actually slower on NTFS (at least not significantly), but the delay between each individual file is just a tiny bit longer. That little delay really adds up for thousands of files. (Side note: From what I've read, this is one of the reasons git is such a pain on Windows, since it relies so heavily on the file system for its object database.) Granted, my evidence is merely anecdotal—I don't currently have any real performance numbers, but it's something that I'd love to test further (perhaps with a Mac dual-booting into Windows). Still, my geekiness insists that someone out there already has. Can anyone explain this, or perhaps point me in the right direction to research it further myself?

• How to inspect remote SMTP server's TLS certificate?

  - by Miles Erickson

  We have an Exchange 2007 server running on Windows Server 2008. Our client uses another vendor's mail server. Their security policies require us to use enforced TLS. This was working fine until recently. Now, when Exchange tries to deliver mail to the client's server, it logs the following: A secure connection to domain-secured domain 'ourclient.com' on connector 'Default external mail' could not be established because the validation of the Transport Layer Security (TLS) certificate for ourclient.com failed with status 'UntrustedRoot. Contact the administrator of ourclient.com to resolve the problem, or remove the domain from the domain-secured list. Removing ourclient.com from the TLSSendDomainSecureList causes messages to be delivered successfully using opportunistic TLS, but this is a temporary workaround at best. The client is an extremely large, security-sensitive international corporation. Our IT contact there claims to be unaware of any changes to their TLS certificate. I have asked him repeatedly to please identify the authority that generated the certificate so that I can troubleshoot the validation error, but so far he has been unable to provide an answer. For all I know, our client could have replaced their valid TLS certificate with one from an in-house certificate authority. Does anyone know a way to manually inspect a remote SMTP server's TLS certificate, as one can do for a remote HTTPS server's certificate in a web browser? It could be very helpful to determine who issued the certificate and compare that information against the list of trusted root certificates on our Exchange server.

• Web server with static IP from cable provider

  - by Dmitri

  I have a subscription to 5 static IP addresses. I want to run a web server from behind a router. My network config is as follows: Server's local address is 10.1.10.2, has IIS running on it, port 80 and 443 (IIS is not my fault, had to be done) the server's ip address is static, the subnet mask is 255.255.255.0, gateway is 10.1.10.1, which is the local address of the cable modem / router / gateway thingy. All looks to be in textbook order as far as the LAN goes. I can get to anything on my LAN from any computer on my LAN, whether they have static IP or get it through DHCP from the cable modem/router thingy. however, I have no internet access form any of my LAN computers. I called Comcast tech support and they say they can connect to my modem/router just fine and can actually use it to ping any computer on the internet or any computer on my LAN from the router/modem (i checked, myself, this is in fact the case). However, nothing on my LAN has internet connectivity. I tried pinging the DNS servers, nothing. I tried directly typing in web sites' IP addresses, nothing, so doesn't seem to be a DNS issue. Any Ideas? What malfunction of a router could be causing such weird behavior? nay ideas or educated guesses are very much appreciated.

• Can't setup 3 nodes MongoDB recplica set

• Vboxheadless without a command prompt (VirtualBox)

  - by joe

  I'm trying to run VirtualBox VM's in the background from a service. I'm having trouble starting a process the way I desire. I'd like to start the virtualbox guest in headless mode as a separate process and show nothing as far as GUI. Here's what I've tried: From command line: start vboxheadless -s "Ubuntu Server" In C#: ProcessStartInfo info = new ProcessStartInfo { UseShellExecute = false, RedirectStandardOutput = true, ErrorDialog = false, WindowStyle = ProcessWindowStyle.Hidden, CreateNoWindow = true, FileName = "C:/program files/sun/virtualbox/vboxheadless", Arguments = "-s \"Ubuntu Server\"" }; Process p = new Process(); p.StartInfo = info; p.Start(); String output = p.StandardOutput.ReadToEnd(); //BLOCKS! (output stream isnt closed) I want to be able to get the output to know if starting the server was a success. However, it seems as though the window that's spawned never closes its output stream. It's also worth mentioning that I've tried using vboxmanage startvm "Ubuntu Server" --type=vrdp. I can determine whether the server started properly using this. But it shows a new command prompt window for the newly started VirtualBox guest.

• Win7 Pro x64 task manager hangs when restarting explorer.exe after waking from sleep

  - by Brandon Dybala

  I have a desktop running Windows 7 x64 Pro, set for Hybrid Sleep on a wired network. Wakeup is only enabled from the keyboard (wake on mouse and Wake-On-LAN are both disabled). Sometimes when it wakes up, there is no network connectivity. The notification area icons for both network and volume don't respond to clicks. If I open the Network and Sharing Center, clicking the red X doesn't do anything. Restarting does fix the problem, but I'm looking for a solution that does not require restarting (if at all possible). Drivers are all up to date. I've tried opening Task Manager and restarting the explorer.exe process, but Task Manager freezes for a few minutes, the "New Task" dialog closes, and explorer.exe has not restarted. CPU and memory usage are both normal. One thread suggested making sure the BIOS was set for S3 sleep mode only (not S1 or S1 & S3), but I haven't checked this yet. Going back to sleep and waking back up does not help. So far only a reboot has fixed the issue. System specs: Windows 7 x64 Pro Asus P8Z68-V PRO/GEN3 128 GB Crucial m4 SSD (Firmware version 0309) Intel Core i7 2600 3.4 GHz 16 GB RAM Any ideas? Brandon

• Windows 7 install detects SSD but doesn't list it to install to

  - by Mohamed Meligy

  I'm having quite a weird problem when trying to install Windows 7 SP1 on a new Corsair Force Series 3 SSD to replace a failing HDD in my wife's laptop. When I boot to Windows install, it shows that I have no disks to install to, and tells me to find it a driver to any custom disks I may have. When I go to repair option on the first install window, and then open command prompt Window, I can see the disk using diskpart, and can partition it and format partitions, and then later access them from command prompt and copy files to them. After creating partitions, clicking the "browse" button in Windows install screen that shows no disks available to install Windows to, does show the partitions created by diskpart! So, it does detect the disk and partitions, but refuses to list them as options to install to. People on the Interwebs seem to suggest that just running diskpart "clean" solved the issue for most people, just creating an "active" "primary" partition is al most tutorials suggest. Both got me only as far as described above. The BIOS doesn't have RAID option, changing between "ATA" and "AHCI" (the only available options) didn't make any difference. Might be worth mentioning that this is on a laptop that has Sata III controller for main drive (which I connected the Sata3 SSD to), and Sata II for DVD (which I used for Windows install media). That's what googling brings at least (DELL XPS 15 L502). Any ideas? . Update: The SSD is 460 GB. I tried setting it all as one partition and creating 70-90 GB partition as well (NTFS). More importantly, Windows doesn't list the partition as one it cannot install to (which it does with disks in general when they are small for example). What happens here is different. It doesn't list anything at all. It shows empty list of drives.

• Finding all IP ranges blelonging to a specific ISP

  - by Jim Jim

  I'm having an issue with a certain individual who keeps scraping my site in an aggressive manner; wasting bandwidth and CPU resources. I've already implemented a system which tails my web server access logs, adds each new IP to a database, keeps track of the number of requests made from that IP, and then, if the same IP goes over a certain threshold of requests within a certain time period, it's blocked via iptables. It may sound elaborate, but as far as I know, there exists no pre-made solution designed to limit a certain IP to a certain amount of bandwidth/requests. This works fine for most crawlers, but an extremely persistent individual is getting a new IP from his/her ISP pool each time they're blocked. I would like to block the ISP entirely, but don't know how to go about it. Doing a whois on a few sample IPs, I can see that they all share the same "netname", "mnt-by", and "origin/AS". Is there a way I can query the ARIN/RIPE database for all subnets using the same mnt-by/AS/netname? If not, how else could I go about getting every IP belonging to this ISP? Thanks.

• Debugging UI Problems in IE8 (Was IE8 on Windows 7 Authentication Mess)

  - by alharaka

  UPDATE: I think the real question I need to ask here is: how does a technician debug UI problems with Internet Explorer, and not HTML rendering issues that have pretty good tools? I am aware of the SysInternals tools and others mentioned below, but maybe I am not harnessing their power properly. Someone else in the TechNet forum I mentioned had a similar issue. Again, I have lots of data, I am not sure how to properly interpret it. ORIGINAL POST: So I tried the venerable Technet Forums to solve this isse. In short, the Windows Security dialog has no place to put credentials, rendering pretty much useless. This happens to apply for a whole bunch of our intranet websites, and only a select number of users with a few laptops have this problem. It ends up looking like this. Things I have tried so far: Disabling local Group Policy (not domain connected) Disabling local Security Policy Resetting IE settings A few system restores Re-registering a bunch of IE DLL's and all other steps here Reinstalling IE8 (dism /online /disable-feature /featurename:"internet-explorer-optional-x86, reboot, dism /online /enable-feature /featurename:"internet-explorer-optional-x86, and reboot) And SFC scan, which found nothing Still, nothing. Not only am I fed up, but I have begun to really work with APIExplorer and Procmon as mentioned in the Technet original because I want to know WHAT is happening, not just fix it. Any thoughts?

• CD and DVD burning very slow with LG DVD Burner

  - by Om Nom Nom

  I have an HP m7560in Desktop which came with an LG DVD burner. As far back as I can remember, it has been having problems in burning discs. It used to take about one and a half hour to burn 4 GB of data on a blank DVD-R. I am using Nero and ImgBurn and I usually select 8x speed for burning. I used to run XP earlier and now I run Windows 7 on it, but I face the problem on both. I have already checked that DMA mode is selected in the IDE controllers' properties. On XP, uninstalling the IDE controllers and DVD drive from the Device Manager, rebooting and letting it install the drivers again fixed the problem for a while, but after a couple reboots, the problem used to come back. On Windows 7, even doing that is not fixing the problem. In fact, in Windows 7, the burning process doesn't even begin. Imgburn gets stuck on the first stage (of writing Lead-In), and it never progresses until I turn off / reset the computer. I checked the disc info after this happened, and the disc still shows empty and ready to be burned on, so it's obvious that it didn't even touch the disc. I have already had the drive replaced once by HP, but it didn't fix the problem. Do you guys have any suggestions? (Note that Windows Updates doesn't give any newer driver for the controllers, or any other components for that matter).

• How do I improve my incremental-backup performance?

  - by Alistair Bell

  I'm currently using the traditional rsync+cp -al method to create incremental/snapshot backups of our server tree. The backups are going onto a pair of eight-disk towers connected to the backup machine (a Sandy Bridge machine with 16 GB of RAM, running CentOS 5.5) via four eSATA connections (four disks per connection). Each disk is a regular 2 TB disk, so we have 32 TB of disk space connected to the backup machine. We're backing up about 20 TB of data on the servers with this. The problem is that each daily backup is taking more than 24 hours, and the real time-killer isn't the actual rsync, but the time it takes to perform a cp -al of the tree locally on the backup machine. It's taking more than 12 hours just to make the shadow copy of the tree, and as far as I can tell the performance backlog is at the disk (top shows the cp using a lot of RAM but not a lot of CPU and mostly in uninterruptible-sleep state) We have the server data split into four major volumes (and a few minor ones), and each of these backups runs in parallel (with some offsets in the cron to try to get some disks' cp done first). There are two volumes on the backup drive, both striped LVM volumes of 16 TB each. So obviously I need to improve the performance because it's unusable as it stands. The first question is: when CentOS 6 comes out, with support for btrfs, will making snapshots of subvolumes with btrfs substantially increase this performance? The second is: is there a way, with ext3 or something else supported in CentOS 5 or 6, to 'encourage' it to put the directories/inodes in one part of a volume (which could happen to be the part that's on an SSD, via LVM) and the files in another? That would presumably solve the problem, but I don't know of ways to hint ext3 like that.

• Is it possible to extract contents of a ThinApp container?

  - by rsk82

  Is there possible to extract such packages made by somebody else. Ok, so if there is no general way of extracting such archives, which can be a huge exe file or tiny exe starter with huge packed *.bin file with main files of an app that is to be run in portable way - is there a way to set an option in compilation *.ini file or other way to make such package able to be extracted. I remember I read somewhere that somebody created a tiny program (in was mentioned in vmware forums as far as I can remember, it was a crude thing coded for private use and I never managed to download it) to sit with main portable application and if such application has an open/save file dialog, it is possible to navigate to that program which virtually sits in the program files alongside main app from within the main app, and such program would scan all files that it can see and somehow is able to distiguish a real file from virtual one, and save all virtual files in a structure that is similar to the initial compilation folder from which portable app was created. I know that it is a very round-about way of doing things, but maybe the only one feasible. Nevertheless any news on this front ? Do antiviruses can somehow unpack these things ? Maybe they must buy a code or license for it from VmWare ? Edit: I found http://communities.vmware.com/thread/257433?tstart=600 and still trying to make sense out of this. Wrong, this was about moving old version of thinapp to win7.

• nginx 301 redirect to subfolder on primary domain

  hello there, sorry for my poor english. i just set up wordpress on my vps, so far its the only item on my site. there for seo reason, i think is better redirect all primary domain to the blog folder. primary domain is example.com wordpress is at example.com/blog what i want is rewrite www.example.com and example.com to example.com/blog. googled got some scripts, and make some change paste into nginx config file. here is: #301 redirect www to non-www server { server_name www.example.com; location = / { rewrite ^/(.*) http://example.com/$1 permanent; } } #301 non-www to subfolder server { server_name example.com; location = / { rewrite ^/(.*) http://example.com/blog$1 permanent; } } it works at some degree, successfully redirect to example.com/blog. the only problem is i get 404 not found error. then i only make nginx redirect www to example.com/blog. ok, this time i can access blog page. i know there is something wrong in the non-www to subfolder script. but do not how to fix it :(

• Server and Network Lag

  - by DanSpd

  At my home I have a server and my computer. Server has Windows Server 2008 Standart 64 bit installed and then my computer has Windows 7 64 bit installed. My home router is DIR-615 My server has a game server installed on it and basically total open connections on server are around 700. Once its around 700 server and then whole home network lags really badly. My internet connection is good and only around 600kb/s is being used out of 2mb/s (real download/upload speeds). So far I assume that my router has a connection limit and with server + my computer connections it peaks at around 1k and lags everything. Another assumption server lag comes from connection limit. On the internet I have read that standart version of server has connection limit of 700 + 10 reserved. I do not rmember where I found that information but it was on microsoft website. So I have two options. First is to upgrade my router to Netgear FVS318G-100 and second is to change connections limit on server. Any advices? Thank you

• Help building maya render node spec

  - by Ak

  Hi there, I'm looking to build 4x Maya render slaves/nodes for a friend of mine when his project gets green lit. The project involves MentalRay and lots of glass. I'm unsure if the new i7's 9xx or 8xx with hyper threading will do any better than a core 2 quad of the same (or close enough) speed. Does hyper threading make a difference to Maya or is it more performance per core based? I'm sure he's prefer I'd build another render node than pay for a bleeding edge CPU that only adds fractionly more GHz. -- The rest of the spec so far: 4Gb - 8Gb ram 64 bit OS: Probably Windows 7 (I know Linux is free, but want to build something my friend can support himself as easily as he supports his own workstation) 1TB HDD to hold textures, Maya files and renders which will be copied to central storage later Mobo with on-board video, gigabit NIC 500 - 650 watt PSU Desktop case something like a: Cooler Master ATCS 840 The machines will sold afterwards if necessary. -- If anyone has had experience in Maya and has done any tests with the new CPUs vs. the older ones I'd really appreciate your input.

• ESXi Server with 12 physical cores maxed out with only 8 cores assigned in virtual machines

  - by Sam

  I have an ESXi 5 server running on a 2-processor, 12-core system with hyperthreading enabled. So: 12 physical cores, 24 logical ones. On this server are 4 Windows 7 VMs, each configured for 2 processors, each running VMware Tools. Looking at my stats in vSphere, my "core utilization" is constantly maxed out. Yes, these machines are working hard, but only 8 cores have been allocated. How is this possible? Should I look into reducing the processor count per machine as in this post: VMware ESX server? I checked to ensure that hardware virtualization is enabled in the BIOS of the machine (a DELL R410). I've also started reading up on configuration, but being a newbie there's a lot of material to catch up on. It also seems I should only bother with advanced settings and pools if I'm really pushing the load, and I don't think that I should be pushing it with so few VMs. I suspect that I have some basic, incorrect configuration setting, but it's also possible that I have some giant misconceptions about virtualization. Any pointers? EDIT: Given the responses I've gotten so far, it seems that this is a measurement problem and not a configuration problem, making this less critical. Perhaps the real question is: How does the core utilization of the server reach a higher percentage than all individual cores' core utilization, and given that this possibility makes the metric useless for overall server load, what is the best global metric for measuring CPU load on hyper-threaded systems?
