Reference Dell T610 PERC 6i - very slow RAID rebuild

Hi all, I have a DELL T610 with a Controller PERC 6i with 4 x 1 TB SAS 7.2 K disks configured as a RAID6. 1 of the drives has failed, I installed the new drive, but reconstruction is only 44% after 36hrs! Why is it so slow? Any ideas would be greatly accepted.

RAID 6 is well known for its performance of poor\slow. This is the only function is to be safer than RAID 5, not to be fast and cheap.  With parity RAID, to rebuild the whole picture.  They have been known to go for a week or more before they are finished, according to the size and speed of players.

Kind regards

  • Reference Dell 2950 Perc 6/i Raid card device driver

    Good morning community, I'm trying to find the Dell 2950 Perc 6/i Raid adapter Device Driver for Windows 2008 R2 Standard OS. Thanks in advance for your help. Modem489

    You don't need to load a driver for the PERC 6 / i in Server 2008 or newer version, the driver is 'native' for Windows.  If you think that you need a driver, I suspect it is because you tried to install and it is not all discs.  If Yes, do not forget that PERC does NOT support RAID/JBOD, then you must configure disks to a virtual disk (VD, matrix RAID) before they can be presented to the OS.  It can be configured in the CTRL-R utility (be sure to check the boxes of progress/Initialize options too).

  • Reference Dell T610 vmware running

    Hello world

    I have a Dell T610 I just add two 600 GB hard drives for. I have difficulties to get the vmware to recognize the two new drives... I restarted the controller of the virtual machine, but it still does not see the readers when I go to the configuration and storage and the rescann. I am new to vmware, so I am lost on what to do next.

    No, the PERC will support up to 64 virtual disks (windows)... they can be in their own RAID 1, separate from the existing RAID?.

  • Reference Dell T610 with 5 hard drive problem (5x2TB) while create RAID 5 with all the HARD drive. :(

    Dear Sir.

    While I have already configured the RAID 5 with 5 disks, then the OS (windows 2008 R2) installation step I saw 2 separate partitions. and can I install it on the partition with only 2 TB. Another, we can't. So during my installation completed OS, then I can use only 2 TB, for another volume is about 5 TB can't do anything. Can I do the RAID 5 with 5 disks (10 TB)?

    I wait your helpful to my set.

    Thank you.

    This is new server, there is not any data yet so I can reinstall. What I want is that I just want to RAID 5 until I started my DC project. I already look for how to convert to GPT, but I'm not at all.  I know that I can't convert GPT as the OS in the same disk but that is because I try to configure RAID 5 and OS, but while over OS I do not see another 5 to just see only 2 TB.

    I don't understand most of what you wrote.  You must activate the UEFI (below), then convert to GPT before installing Windows.

    How can I install on a UEFI system?

    The T610 supports UEFI, but must be allowed.  Start the BIOS (F2) Setup and change the boot mode in the UEFI instead of BIOS/inheritance.

    Your alternative is to create a RAID 5 using all disks, but the definition of the size as something as small as 2 to, then another RAID 5 with space remaining.  Each table will be displayed in Windows as a separate 'drive' - you can then install normally in the smallest 'drive '.

  • Reference Dell R710 - Perc 6 / disc matrix (support 4 TB?), I supported

    Hi all

    Since then, we want to upgrade the hard drive 2 TB (3.5 inches) for a large as 3/4 to.
    Is there information on the matrix of disc official supported of PERC 6 / i?

    We use Seagate 2 TB 72kRPM (bought from Dell) on our R710 servers. If the PERC 6 / I can't stand 3 to/4 TB disk. Is it possible to order the H700 support 4 TB drive adapter?

    We have installed the latest firmware /bios,
    -Perc 6/i: 6.3.3 - 0002, A-00
    -System BIOS: 6.4.0

    Thank you and best regards,

    PERC 6 does not support disks larger than 2 TB. The H700 is supported in the R710 and supports disks larger than 2 TB. I would not, however, use desktop or NAS drives.

    It is normal so he can make a full discharge of the battery as part of his learning cycle every 90 days. Make sure that this isn't that. If this isn't the case, the reason, give it 24 hours. If it is fully charged, update the system (including RAID firmware, driver first) firmware. If not fully charged yet or it reproduces quickly, then replace the battery - power down to replace.

  • Very slow start and run for Dell Inspiron 6400 XP times

    "I have a problem with an Inspiron 6400 brought to ' horribly slow start and run time.  XP Pro 32 bit SP3 patched up to date.  Cleaned up a lot of "undesirable", as the partially uninstalled programs, cleaned the files temporary etc. with CCleaner, cleaned and optimized the registry afer all the cleaning has been done, defragmented, tried to start without any of the boot files, disabled all unnecessary services and uninstalled virus checking software, (but ran several anti-virus controls) etc. - no help.   Safe Start Mode is faster, but... not at all normal - 1 1/2 minutes of screen to logon instead of close to 3 minutes.  A lot of memory (2 GB), which rises to 600 to 700 MB runnng all the stuff I've tried.  Hard drive is 1/3 used out of 120 GB with a 2 GB swap file.

    One thing I'm still scratching my head over - beyond the horribly slow boot - is very slow access to files even though everything seems to work normally, but as molasses in January.  Looking at the performance of the Task Manager tab when I run a copy of a file (whether via a cmd window or with Windows Explorer), I see a near max processor would be and the other with a small business.  Even if the customer says he had been getting worse for some time, after checking and cleaning of all things 'normal', my next thought was perhaps a bad disk or disk controller driver, but chkdsk ran very well (although it took hours) even if I ' d I have already updated all drivers (and even the DVD firmware and BIOS) on the Dell web site.  Oh, and I ran Dell Diagnostics (from bootable CD) updates all with no errors found.  And access to the slow file even with symptoms had max-processor occur with a copy of the file on a USB key that seems to eliminiate the hard disk, the disk controller and the pilot.

    The other interesting part of the display for a file copy task manager is that the processes tab simply shows System Idle 97 to 99%, with a percentage of casual for other processes as Explorer while I see 1 max out procesor on the performance tab.  That the same copy on your desktop shows 3-4% of the CPU usage and who is with active antivirus software.  I'm almost ready to fall toward a Windows reinstall, but would like to find the real reason behind this problem of puzzle...

    It of almost as if he's using PIO instead of DMA disk access, but... don't know how/where to test this.

    Look at:
    and

    Solved!   Thanks for the links, especially to each other.  An old but still a goodie!

    For those who have enquring spirits (and anyone else who stumbles across this thread), the primary IDE controller has been set to PIO and locked it.  Who would have thought that Windows slowly reduced the transfer speed, whenever he saw 6 errors on an IDE device until it has been reduced to PIO and then he locked it?  But the procedures described in the link of winhlp.com showed how to solve the problem.

    There are actually several problems that led to the final symptoms.  According to KB817472, the Atapi.sys has been improved in XP SP2 only degrade the speed of transfer on 6 consecutive errors instead of 6 cumulative errors.  And even though everything I have (Microsoft update) was seen and showed that this area was to SP3, I found that the driver for the controller layer IDE was the SP2 version.  Someone ran sfc previously perhaps?

    Oh, and I know now that the Task Manager process tab does not time processor kernal, but the performance tab.  Good to know...

    Thanks again to all who have responded.  Starting at the time of connection-question now is 40 seconds.   You'll love Untra DMA mode 5.   There is still a lingering question in my mind, since I've had the same symptoms of slow copy of a file on a flash drive.  Perhaps a link in some way to the way that Windows treats a flashdrive as a "drive"...

  • Reference Dell upgrade memory T610

    I have Dell T610 with a CPU E5506 server. I want to get out all of the memory from the server and install the new memory 4 grade 8Gb 2Rx4 RDIMMS DDR3 1333 MHz LV (Snpp9rn2c / 8g).

    Will be ok? I got 32GB? Assorted memory work correctly with CPU E5506?

    The 8 GB memory you bought is a low voltage given double revenu3 type double row of double error correction in modules of memory in line with Government (on the address lines?). They are compatible with your T610 and should work without problems (assuming that there are no unknown hardware failure).

    What slots place you the RDIMMs will depend on you specify settings of the BIOS memory mode. If I understand correctly, this in turn can affect the speed of memory.

    I would 1st set BIOS memory mode 'Advanced ECC' and place your RDIMS in the 4 closest slots of CPU1 leaving farthest 2 empty slots. Then I would run a memory benchmark to check performance.

    You could also try changing the mode memory BIOS to "Optimized" and place the RDIMMS 3 white slots with 4th in the black slot more away from the CPU (marked A4). Then run a cue memory point and compare with the above configuration.

    Each configuration should give you 32 GB.

    You don't mention this type, the size or the number of DIMMs you had previously installed in your system, it is therefore impossible to tell if they can be reused or how. But since you mention that you replace them, I guess that's irrelevant anyway. However, if your old memory was UDIMM type (without buffer only = no records on the data lines), it's safe to say that you can not mix with of the UDIMM RDIMMS. If you old memory was of RDIMMS you can reuse them (but if they are not the type of low voltage, you will get the benefit of low voltage of your new memory because it will work under tension will use and therefore consume more power than would otherwise be the case).

    Good luck.

  • Reference Dell T300 RAID additional Install

    Currently I have a T300 Dell with a RAID 1. Current readers are almost complete, so I have 2 drives more than I am about to install in another RAID 1 on the server. Ask yourself what are the steps needed to do this successfully.

    Currently, I plan the following:

    1 stop server

    2. install the new discs on the front of the server.

    3 Server boot in OS (Server 2008)

    4. use the Dell software to configure new RAID 1.

    Is that going to succeed?

    1 skip this step.

    2. install new disks on the front of the [hot] Server.

    3. no need to 'boot' in OS.

    4 use the Dell [OMSA] software to configure new RAID 1.
