  • The difference between desktop-series HDD drives and server-series

    - by FractalizeR
    Hello. What are the main differences between desktop-series hard disks and server-series? The obvious things I can see are: durability (server hardware mostly more qualitative and have more warranty) and power consumption (server hardware more focused on performance, than on power economy). Also server disks are usually a little faster, but it seems, that it is not always the case. May be there are some other reasons, that make you choose server-oriented series (Seagate ES drives, for example) over desktop-oriented ones (Seagate Barracuda series)? What are they?

  • Migration with SysPrep, ImageX and

    - by Jack Smith
    I know that you can use SysPrep and ImageX to create a prepared image that can be used on several systems but the question is. How well does it work in a corporate environment of moving machines from old hardware off to new harddrives and new hardware? EDIT: The system runs accounting software and databases. So would SysPrep remove all License keys and other information which means would cause problems right? Would something else be a better option even though there are heavy costs involved? Currently, when I clone/copy the drive, Windows will black screen on me. So I need something with differential hardware support?

  • Cannot resize OS X partition

    - by David Pearce
    I am trying to resize my existing Mac OS Extended partition on my Macbook to install Windows 7 (using steps similar to these), but when ever I go to apply the changes, I get this error: Partition failed Partition failed with the error: The partition cannot be resized. Try reducing the amount of change in the size of the partition. The total capacity of the hard drive in question is 260GB, with the entirety being taken up by the OS X boot partition. There is I am aiming to shrink that partition down to 60GB. How can I fix this problem? I have been reducing the amount of change by 10GB each attempt, but it still is not working. I assume the problem is that there is not a large amount of continuous space on the device. Is there some way to can do a manual defrag that would rectify this problem?

  • What usb-bootable utility should I use to copy SATA hard drives?

    - by Steve Brown
    I have a computer that only has two SATA connections and I need to copy one SATA hard drive to another. Since I have to unplug the CD drive to copy the drives I need a USB-bootable utility. I have an old school copy of Norton Ghost (CD based): Ghost has always worked well for me in the past - I see there is a new "version 15" out but I'm not sure if it is worth buying. A friend has Acronis True Image on a USB drive: We tried to use that on the computer but it was unable to copy both partitions (restore partition and main partition). Of course there may be some problem with the drive that is keeping Acronis from working (it is just exiting with a lame error about not being able to copy the disks and no error code or detailed information), but I'm interested in knowing if there is a better, more solid, or widely used solution that I should invest in. What usb-bootable utilities can I use to copy SATA hard drives?

  • What would I need to do to clone a Linux install to another machine?

    - by Marcus Hughes
    Basically, I want to make an image of one Linux install I have, and distribute it over similar (if not identical) spec machines on a network. I know it is possible, however am unsure of what needs to be done before I make the image of the install to ensure it works correctly on all machines. First think I know needs to be done, is remove all interface configuration, as I assume it would just jump to eth1 (and possibly use the same MAC), as it wont locate the network interface it had before, how would I do this so it auto detects and goes to eth0 again? Is there anything else I would need to do to the install before I make its image?

  • General monitoring for SQL Server Analysis Services using Performance Monitor

    - by Testas
    A recent customer engagement required a setup of a monitoring solution for SSAS, due to the time restrictions placed upon this, native Windows Performance Monitor (Perfmon) and SQL Server Profiler Monitoring Tools was used as using a third party tool would have meant the customer providing an additional monitoring server that was not available.I wanted to outline the performance monitoring counters that was used to monitor the system on which SSAS was running. Due to the slow query performance that was occurring during certain scenarios, perfmon was used to establish if any pressure was being placed on the Disk, CPU or Memory subsystem when concurrent connections access the same query, and Profiler to pinpoint how the query was being managed within SSAS, profiler I will leave for another blogThis guide is not designed to provide a definitive list of what should be used when monitoring SSAS, different situations may require the addition or removal of counters as presented by the situation. However I hope that it serves as a good basis for starting your monitoring of SSAS. I would also like to acknowledge Chris Webb’s awesome chapters from “Expert Cube Development” that also helped shape my monitoring strategy:http://cwebbbi.spaces.live.com/blog/cns!7B84B0F2C239489A!6657.entrySimulating ConnectionsTo simulate the additional connections to the SSAS server whilst monitoring, I used ascmd to simulate multiple connections to the typical and worse performing queries that were identified by the customer. A similar sript can be downloaded from codeplex at http://www.codeplex.com/SQLSrvAnalysisSrvcs.     File name: ASCMD_StressTestingScripts.zip. Performance MonitorWithin performance monitor,  a counter log was created that contained the list of counters below. The important point to note when running the counter log is that the RUN AS property within the counter log properties should be changed to an account that has rights to the SSAS instance when monitoring MSAS counters. Failure to do so means that the counter log runs under the system account, no errors or warning are given while running the counter log, and it is not until you need to view the MSAS counters that they will not be displayed if run under the default account that has no right to SSAS. If your connection simulation takes hours, this could prove quite frustrating if not done beforehand JThe counters used……  Object Counter Instance Justification System Processor Queue legnth N/A Indicates how many threads are waiting for execution against the processor. If this counter is consistently higher than around 5 when processor utilization approaches 100%, then this is a good indication that there is more work (active threads) available (ready for execution) than the machine's processors are able to handle. System Context Switches/sec N/A Measures how frequently the processor has to switch from user- to kernel-mode to handle a request from a thread running in user mode. The heavier the workload running on your machine, the higher this counter will generally be, but over long term the value of this counter should remain fairly constant. If this counter suddenly starts increasing however, it may be an indicating of a malfunctioning device, especially if the Processor\Interrupts/sec\(_Total) counter on your machine shows a similar unexplained increase Process % Processor Time sqlservr Definately should be used if Processor\% Processor Time\(_Total) is maxing at 100% to assess the effect of the SQL Server process on the processor Process % Processor Time msmdsrv Definately should be used if Processor\% Processor Time\(_Total) is maxing at 100% to assess the effect of the SQL Server process on the processor Process Working Set sqlservr If the Memory\Available bytes counter is decreaing this counter can be run to indicate if the process is consuming larger and larger amounts of RAM. Process(instance)\Working Set measures the size of the working set for each process, which indicates the number of allocated pages the process can address without generating a page fault. Process Working Set msmdsrv If the Memory\Available bytes counter is decreaing this counter can be run to indicate if the process is consuming larger and larger amounts of RAM. Process(instance)\Working Set measures the size of the working set for each process, which indicates the number of allocated pages the process can address without generating a page fault. Processor % Processor Time _Total and individual cores measures the total utilization of your processor by all running processes. If multi-proc then be mindful only an average is provided Processor % Privileged Time _Total To see how the OS is handling basic IO requests. If kernel mode utilization is high, your machine is likely underpowered as it's too busy handling basic OS housekeeping functions to be able to effectively run other applications. Processor % User Time _Total To see how the applications is interacting from a processor perspective, a high percentage utilisation determine that the server is dealing with too many apps and may require increasing thje hardware or scaling out Processor Interrupts/sec _Total  The average rate, in incidents per second, at which the processor received and serviced hardware interrupts. Shoulr be consistant over time but a sudden unexplained increase could indicate a device malfunction which can be confirmed using the System\Context Switches/sec counter Memory Pages/sec N/A Indicates the rate at which pages are read from or written to disk to resolve hard page faults. This counter is a primary indicator of the kinds of faults that cause system-wide delays, this is the primary counter to watch for indication of possible insufficient RAM to meet your server's needs. A good idea here is to configure a perfmon alert that triggers when the number of pages per second exceeds 50 per paging disk on your system. May also want to see the configuration of the page file on the Server Memory Available Mbytes N/A is the amount of physical memory, in bytes, available to processes running on the computer. if this counter is greater than 10% of the actual RAM in your machine then you probably have more than enough RAM. monitor it regularly to see if any downward trend develops, and set an alert to trigger if it drops below 2% of the installed RAM. Physical Disk Disk Transfers/sec for each physical disk If it goes above 10 disk I/Os per second then you've got poor response time for your disk. Physical Disk Idle Time _total If Disk Transfers/sec is above  25 disk I/Os per second use this counter. which measures the percent time that your hard disk is idle during the measurement interval, and if you see this counter fall below 20% then you've likely got read/write requests queuing up for your disk which is unable to service these requests in a timely fashion. Physical Disk Disk queue legnth For the OLAP and SQL physical disk A value that is consistently less than 2 means that the disk system is handling the IO requests against the physical disk Network Interface Bytes Total/sec For the NIC Should be monitored over a period of time to see if there is anb increase/decrease in network utilisation Network Interface Current Bandwidth For the NIC is an estimate of the current bandwidth of the network interface in bits per second (BPS).

  • ext4 jbd2 journaling active even on empty filesystem

    - by Paul
    I have been having several issues with my ext4 filesystems that seem to be due to jbd2 journaling. I made a related post here and am rephrasing it with the hope that someone may be able to help. For a minimal example, I start with an empty 8gb USB stick and use gparted to create one ext4 partition. The command used by gparted when creating the ext4 file system is: mkfs.ext4 -j -O extent -L DataTraveler8gb /dev/sde1 I check the filesystem with gparted: e2fsck -f -y -v /dev/sde1 and I mount it: sudo mount /dev/sde1 /media/test The disk is empty, but the journaling is very active on this disk (/dev/sde1). The other disks are ext4 SSDs formatted similarly. A snapshot of iotop: % sudo iotop -oPa Total DISK READ: 0.00 B/s | Total DISK WRITE: 2027.21 K/s PID PRIO USER DISK READ DISK WRITE SWAPIN IO COMMAND 262 be/3 root 0.00 B 56.00 K 0.00 % 0.18 % [jbd2/sda1-8] 29069 be/3 root 0.00 B 0.00 B 0.00 % 0.16 % [jbd2/sde1-8] 891 be/3 root 0.00 B 4.00 K 0.00 % 0.03 % [jbd2/sdc1-8] What is jbd2 doing with /dev/sde1? If I follow the same steps with a larger 2Tb disk, iotop indicates this empty disk is constantly being written to by jbd2 at the rate of Mb/s as soon as I mount it. On the other disks, which have the OS and /home, I have tried to find if any files are being modified by processes to cause this behavior but couldn't find any. I also moved many of the disk intensive process to use a tmpfs. And used noatime. I have another non-SSD hard disk on this machine, /dev/sdb, that is also ext4 but was not formatted by gparted (given to me by a coworker). It does not appear in iotop. So I am assuming there an issue with gparted. Any suggestions are appreciated. Also any tips on how to modify existing partitions to fix the issue without having to start from scratch would be great. There are some posts related to jbd2 but they didn't help (eg. here).

  • Disabling partition just for one OS on multi-boot system

    - by Emiswelt
    Hi Regarding to the solution there: http://serverfault.com/questions/36385/how-can-i-mount-a-hard-drive-as-read-only-on-windows-xp I have a system with three partitions. One runs windows 7, one runs windows XP and is for some experimental programming and testing. I don't want to mess up anything, so I am going to disable the windows 7 partition like described on the linked page above from windows XP to protect the operating system. When I do this, is the windows 7 partition only disabled for the running XP os, or is the windows 7 partition rendered unbootable? with best regards

  • Simple Workstation Imaging Solution?

    - by user23087
    I need a fairly cheap imaging solution for Windows XP corporate desktops. Ideally, I'd be able to set up a desktop exactly as we want it, create an image, deploy this image to a server, then boot a new desktop to a CD/USB Drive/Network and quickly set up the workstation. Ideally, each computer would also have a unique workstation name. Any ideas? Right now I'm using a custom built Linux DD solution, but it's slow, not network-based, can't image multiple computers at the same time as there's only one copy on a USB drive, and can't uniquely name the computers. Thanks, Will

  • How can I free up some space in my C: drive?

    - by Faraaz
    Each time I try to save a file, I get a message from my computer (with Windows 7) that asks me to free up some space in my Drive C before being able to save my intended file. But the more I search for extraneous files to delete, the more I get frustrated. I simply can't find out what "extra" file(s) I have that are occupying about 20 gigs of my C drive. As far as I know I save all the downloadable stuff to my other drives, and the most part of what I do with my computer is just Internet browsing. Would you please help me find the file or files that have occupied so much space in my Drive C so that I can remove them?

  • Are there any Microsoft Exchange Clients for iOS and Android that store their local data in an encrypted manner?

    - by Zac B
    I don't feel like this is a product recommendation question, more of a "does this tech even exist and is it feasible" question, but if I'm wrong, feel free to give this question the boot. Context: Our company has a bunch of traveling employees who access the company's Exchange server via thier iDevices or android phones, but because of the data protection laws in the state where our company is based (and the nature of the data our company works with), a recent security audit found that all mobile devices (laptops, phones, etc) operated by our company need to have all company correspondence and related data encrypted all the time. For laptops, that was easy: BitLocker or TrueCrypt, problem solved. For phones and tablets, however, I'm stumped. Sure, you can put lock screens/passwords on the phones, but the data is still accessible via external extraction, as law enforcement authorities already know. Question: Are there any clients for Microsoft Exchange that run on iOS or Android which store local data encrypted? The people using our mobile devices do a lot of their work while offline, so just giving them OWA access with SSL connection security isn't enough. Are there apps/technologies that present an additional login credential prompt to decrypt locally stored data in the app's storage area on the phone? My gut reaction when I started looking into this was "that doesn't sound like something Apple would allow into the App Store", but I've been wrong before...

    Hi, I have this server which has it's physical disks in RAID 5 controlled by a 3com raid controller. size of the stripe unit is unknown for the moment (Can check tomorrow in the office). I need to install windows server 2003 ENT and create 2 partitions (OS, Data). I'd like to create the partitions before the installation on windows server. They have to be aligned properly. I have the newest version of gparted on a disc but I have no clue if this is the right tool. Can someone point me in the right direction? Thanks

  • Setting up a Pagefile and Partition in Server 2008

    - by Brett Powell
    I am setting up 18 new machines for our company, and I have instructions from my new boss on setting up a Pagefile and Partition. I have looked at their existing machines to base the new setups off of, but there is no consistency between any 2 machines, which has left me extremely frustrated to say the least. My instructions are... 1) Set a static pagefile (use recommended value as max/min), set it on SSD if SSD available. 2) Make 3 partitions: C: is used for OS and install files D: is used for backups on machines with a SSD. On machines without SSD create a D: partition for pagefile (2*installed RAM for partition size) E: must be the partition hosting user files I have never messed with Pagefiles before, and looking at their existing machines is offering no help. My questions are... 1) As the machines I am setting up have no SSD (just 2 SATA drives) does it sound like the Pagefile should be setup on the C: (primary) drive or the D:? The instructions are vague so I have no idea. 2) As C: and D: are both Physical drives, does it sound like C: should be partitioned out to create the E: drive or D:? Thanks for any help I can get. I am extremely stressed out under a massive workload right now, and these vague instructions are quite infuriating.

  • Linux laptop encryption

    - by kaerast
    What are my options for encrypting the /home directories of my Ubuntu laptops? They are currently setup without any encryption and some have /home as a separate partition whilst others don't. Most of these laptops are single-user standalone laptops which are out on the road a lot. Is ecryptfs and the encrypted Private directory good enough or are there better, more secure, options? If somebody got hold of the laptop, how easy would it be for them to gain access to the encrypted files? Similar questions for encrypted lvm, truecrypt and any other solution I may not be aware of.

  • When did my Mac's HD last sleep?

    - by flipdoubt
    Is there any app or log that says when my MacBook Pro's hard drive last went into sleep mode? I ask because each night when I close the MBP's lid without being plugged into a power source, the power light goes into its snooze rhythm but the battery is half-drained by the next morning. It certainly looks like it is asleep, but the power drain seems to indicate otherwise.

    i couldn't think of a better place to ask this question, so here it goes. we're putting together a dedicated server for a website that will initially host the web server and the mysql database. as the website grows, we'll move the database to a different server and this machine will eventually only server the actual website. so the question is ...does my configuration look okay? it's the first time i'm building a server from scratch so i want to make sure i don't combine components that don't fit or something. things like ..do the drives i picked work for the hot swap ..etc. what do you guys think? am i good to go with this configuration? :) Chassis: Supermicro SuperServer 6016T-MTHF (6x DDR3 SDRAM - ECC DIMM 240-pin, 2x LGA1366 Socket, Power Provided: 600 Watt, 4 (free) x hot-swap - 3.5") CPU: Intel BX80614E5620 Xeon E5620 Processor - 4 Core, 2.40GHz, LGA 1366, 5.86GT/s QPI 12MB Cache, 64-Bit, 80W, HyperThreading Memory: Crucial CT51272BB1339 4GB PC10600 DDR3 Memory - 1333MHz, ECC, Registered, 1x4096MB (possibly 3 or 4 of them) Hard Drives: Western Digital WD2002FAEX Caviar Black Hard Drive - 2TB, 3.5", SATA 6Gbps, 7200 RPM, 64MB (possibly 2 or 3). thank you very much for any professional advice :)

  • WinXP: File Record Segment nnnn is unreadable?

    - by chris
    I'm pretty sure that the drive is toast, except for the fact that this error is only showing up on one partition (it's out of a Dell computer, and has a couple of Dell partitions, which boot and work fine.) I've already purchased another hard drive, and re-installed WinXP, but when I re-connect this drive and reboot, I'm getting thousands of these errors. Is there any chance of recovering any files off this? Should I prevent XP from trying to resolve the problems?

  • Win 7 (SP1) Creationg of System Image failure... seems absurd. (0x80780119)

    - by DSKauai16
    This question seems to keep coming up in Microsoft Answers. Unfortunately, it never seems to be solved... on Microsoft Answers. Hopefully someone here will have a better idea. I'm trying to create a system image. It's not working. I have just re-installed windows as of a few hours ago. I have an admittedly older Western Digital 148 GB USB portable HDD which is not just completely empty, but I even did a long format with the NTFS file system just to be sure. The reinstallation of windows and a couple of programs take up 40 GB (seen below) When I try to create a System Image onto the USB HDD, I am told that there is not enough room. Obviously, this is wrong. The screen captures show exactly the steps that are happening to lead me to 0x80780119. I haven't done anything but put on Windows 7 (32bit; SP1) and install some programs. I haven't even done anything with them. There's almost zero in the way of data, and I checked that yes, the HDD works to accept data, send data and work with data. I've used the drive successfully for a long, long time. What's going wrong?

  • Windows 8 will only recognize the Blu Ray ROM, if the install disk is present at boot time

    - by aceinthehole
    If I have the install disk in the blu ray ROM drive at boot time and subsequently remove the disk and replace it with blu ray media everything functions as I'd expect. However, if I have no media present, or another disk in the drive at boot time, then windows 8 does not seem to recognize that the blu ray player is even present in the computer. It is not present in the 'my computer' screen, device manager does not show the player, and scanning for new hardware yields nothing. It seems that the driver is installed and working as expect, what is it about having the windows 8 install disk in the drive or not that would cause this kind of behavior?

The very same VM was copied to another Server running simply Ubuntu Server with KVM and had better I/O Perf. this is how the HDD is shown in the Guest: ata1: SATA link up 6.0 Gbps (SStatus 133 SControl 300) ata1.00: ATA-8: ST3000DM001-9YN166, CC49, max UDMA/133 ata1.00: 5860533168 sectors, multi 16: LBA48 NCQ (depth 31/32), AA ata1.00: configured for UDMA/133 scsi 0:0:0:0: Direct-Access ATA ST3000DM001-9YN1 CC49 PQ: 0 ANSI: 5 sd 0:0:0:0: [sda] 5860533168 512-byte logical blocks: (3.00 TB/2.72 TiB) sd 0:0:0:0: [sda] 4096-byte physical blocks sd 0:0:0:0: [sda] Write Protect is off sd 0:0:0:0: [sda] Mode Sense: 00 3a 00 00 sd 0:0:0:0: [sda] Write cache: enabled, read cache: enabled, doesn't support DPO or FUA I tested with DD: $ dd bs=1M count=128 if=/dev/zero of=test conv=fdatasync 128+0 records in 128+0 records out 134217728 bytes (134 MB) copied, 19.2222 s, 7.0 MB/s on the Host, this same Test will result with 156 MB/s in average. PS: I am using VirtIO and see no error in dmesg.

  • Windows 7 - mysteriously missing free HDD space

    - by sYnfo
    I have Windows7 installed on 50GB (Oops, it should have been 45GB, sorry) partition, and every now and then it gets full, and I have to resize that partition. I always thought it is quite normal. But it happened again today and this time, I'm sure it is not normal, because since last resizing (35GB 45GB) I did not install any new apps or whatever. Also, sum of sizes off all, including hidden & system, root folders and files is ~18GB, yet windows is indicating that all 50GB are used up... Any idea what is going on? EDIT: Great tools everyone! (SourceForge appears to be offline at the moment, I'll check WinDirStat later) Alas, non of them solved my problem just yet... Screenshot from SpaceSniffer: On the right there is some kind of "Unknows Space", any idea what that could be? EDIT2: After those two apps failing to help much I didn't expect it, but WinDirStat actually helped. It showed that those missing 27GB are in my Temp folder (Well, that should have been my first guess anyway). There I found hundreds of ~100MB files, named like HTT????.tmp. After some googling it appears to be a problem with ESET NOD32 antivirus and it's ThreatSense feature. Thank you all for help! :)

  • How useful is hard drive encryption?

    - by D Connors
    So, let's say you have a notebook, and you encrypt the entire hard drive. Whenever you boot it's gonna ask for a password, meaning nobody can access your data without the password. On the other hand, what if your notebook got stolen whilst it was in sleep mode? Is there any protection that the encryption can offer? Thanks
