RAID stands for Redundant Array of Independent Disks.

RAID is data storage technology that allows multiple drives to be used together as a single virtual drive for reasons such as fault tolerance, reliability and performance.

There are several different levels of RAID that determine how the data is stored and the level of redundancy achieved across the drives.

Hi all,

Really need some help please.  Have a small domain network running on 2012 with less than 10 users set up on it that is running painfully slow for all users.  Even saving a 20K file can take a minute.  600MB folder transfer is reporting as needing about 20 hours.

I have just installed this brand new Dell R430 server, 32GB Ram, Dual Xeon Processors, Perc H710 card with 4 x SAS 10K drives in Raid 5 for the main data partition.  Running Server 2012 R2  as a host server and have created a single VM running 2012 Standard which has been set up as a single domain controller/file share with DHCP and DNS server roles. I made sure I updated all of the Dell drivers on the host before installing the VM and have run all updates on both the host and the VM.  There is a brand new 24 port gigabit unmanaged switch into which the server,  a Watchguard T30W Firewall, a Wireless access point, a Synology NAS device and 4 laptops are all plugged in.

I've checked there are no IP conflicts, get a steady ping to the server at <1ms.  DHCP is working fine and there are no issues accessing websites however everything is so slow.

I've disabled VMQ in the advanced properties of the VM Host NIC and also disabled SMB signing so I know the issue isn't with those.

Would really appreciate any pointers.

Thanks

Hello,

I have a PowerEdge 730 with H730 RAID controller. I created a RAID 5 array with 2 x hot spares. The total available disk space is about 4.4TB.

I created a single VD using all the available space.

I installed Windows Hyper-V Server 2016 core. During the install I did not manually create partitions since I intended on having only a single partition of all the available space to allocate to VMs so I just selected the raw disk space, which displayed as 4.4TB. This was the first mistake since now the entire partition is MBR. That being said, it only sees 2TB max.

Now I need to shrink the OS partition to about 500GB so I can create 2nd GPT partition so I can make use of the remaining space.

My second mistake is what complicates the situation a little more. I installed and deployed 3 production VMs assuming I had all the disk space to work with.

I have made a backup of the VMS using Veeam backup and replciation and I moved the production VMs to external storage for the time being so I can adjust the C:\ partition.

Now, my question is... Can I use diskpart to shrink the C:\ partition and then create a second partition with the remaining space on a single VD or do I have to shrink the VD in the RAID utility and create another VD.

Is what I'm trying to accomplish possible without destroying the OS?

I know there is always a risk, which is why I have backups, but I would like to do it with the least amount of down time. I've already had the VMs off…

I’m using integrated to mainboard storage controller in RAID1 mode for my Windows Server 2008R2 system.

So one day I’ve corrupted my system and I’ve restored it from full backup, including MBR.

But I’ve got a message that "BOOTMGR is missing" and first thing I’ve decided to do is to load MS DaRT to repair my boot issue and at first boot MS DaRT found some bootable problems and asked me If I want to fix them. I’ve pressed OK : )

After this regular steps the magic had arisen: PC came to reboot and after reboot the problem still here - "BOOTMGR is missing". So, I thought OK, let’s check the MS DaRT again, and while I press to load USB with MS DaRT my system begins to boot.

What the heck?

Now I’m not able to run my system without MS DaRT and also I even can’t run MS DaRT?
Is it a black magic? Please help me!

We have two servers: power edge r610 and  power edge t610.  Both of these servers are displaying in the front panel error;
    w12228 raid controller battery capacity.

Do we have to replace the batteries or can this be fixed by rebooting the server.

How can I get the batteries part # or model for these servers, so that we can order these two batteries.

I am attempting to configure a RAID 0+1 configuration on a Dell Precision T3600.  The drives were previously in service and want to wipe them clean and start from fresh.  My objective is to destroy all current partitions and create a new RAID configuration.  How can I accomplish this within the BIOS Setup Configuration?  I thought CTRL I would allow me to accomplish my objective, but I am not getting an option for CTRL I during the boot cycle.

I was playing around with software mirroring on a Windows 10 box with two SSD drives. There was no increase in throughput between a single drive and RAID 1. I was under the impression RAID 1 should have increased the throughput because there were two drives filling the pipe as opposed to just one but it didn't change much. Why wasn't RAID 1 better?

I have a Dell T320 server that we just restored from an image backup. It had two (of three) RAID drives in predicted fail, when we removed one to replace it the RAID died immediately. Rebuild of RAID with new drives and then restore from backup went smooth. Now I'm having some trouble.

  1. On boot, it tries to enter system recovery.
  2. If I tell it to boot normally, it tries to load Windows then restarts.
  3. If I go into system recovery, it can't find the Windows installation and asks for drivers or an image to restore. If I load RAID drivers, it finds a Windows install on the RAID volume, which is mapped to the next available drive letter. (Not C:)
  4. Then I can run startup repair and it will prompt for a reboot and boot Windows properly. (With the right volume mapped to C:)
  5. The system runs mostly fine. I have a .NET issue I'm working on but I THINK it's unrelated.
  6. If I reboot the system it goes back to the beginning.

I'm also confused about how it's getting to the advanced boot menu to prompt me to enter system recovery without a Windows volume.

Hi guys,

Scenario:
Dell blade server which has smoke damage due to a fire in the building.
HDD's SATA seem ok.
VMware ESXi

Aim is to get the VM's out.

Is there a way to recover a Raid 10 array of 6 hard drivers, BUT i only have the ability to see one HDD at a time via a PC (maybe I will need some raid recovery software).  I have a dual bay SATA caddy that I intend on using.

Any suggestions people?  Any other ideas?

Many Thanks.

Hello,

       I bought the server about 4/5 years ago, it came with "windows small business server 2011".
This is the chassis
http://www.supermicro.com/manuals/chassis/tower/SC748.pdf

       I replaced all the old hard drives recently and decided to start from scratch with new windows setup. I chose RAID 6 expecting to get about 8GB of usable space(ie from 4 * 4GB disks with 2 disk redundancy) . However I wasnt familiar with the difference between MBR and GPT when partitioning.  I guess I chose MBR if I was prompted, because now that is the partitioning system and Im limited to 2GB per Volume. I created 1 Volume (C drive).

Is there anyway to convert this current bootable volume to GPT or perhaps there is a way to allocate the remaining space to some other drives?

btw, the BIOS version is "American Megatrends Inc. 3.0b, 01/02/2013" but I seem to be having trouble logging into the BIOS now at startup, Ive tried all the usual key combos.  

Any help or suggestions much appreciated

Thanks

I rebooted our file server which is a 2008R2 used only for file services.  There were two Microsoft updates one of which was a service pack update.  It has now been close to two hours and on the screen it still says that it is shutting down.  The blue circle to the left of the text is solid and not spinning.  It has (8) 2 TB hard drives in a RAID 5 array and the last drive is blinking steady green with no other activity.  My question is: Is it possibly still doing something or is it locked up?  I don't know whether I should force another restart or not. Any thoughts?

This is on a Dell Powervault MD1200 which is serving as storage for an ESXI5.5 host.
There are two 8TB disks for this purpose.
They will act as storage for an RHEL VM server.

Had problems getting it working when setting up as one large VD occupying the entire available space: Link

Thought it was the disks - got new ones: same issue.
Decided to create a VD using only 2TB...success! It works as intended. Seems to be some bug in the Linux or ESXI OS.
I am creating more VDs with the remaining space to make sure this will work.

What I am wondering if this is a good idea? Any potential drawbacks? Is it harder to recover from a disk failure or other such problem?

I know it may sound an inappropriate question but I am asked by a client to support that SSD+HDD (SATA) is more productive solution than RAID 5, 10 in certain environments.

The computer is a normal system used to compute patient data. It is a processing system. Patient data stays in drive D in SQL.

Looking for expert opinions.

File of crash dump is attached.
This server had previously crashed several times with error.  DRIVER_IRQL_NOT_LESS_OR_EQUAL
Following this the raid controller driver was updated as the driver name was megasas. However 1 week later it has BSOD with this error.

Windows Server 2016 is running on this server. It is a IBM System x3100 M5 [5457AC1].

I have downloaded Update Express which should run fine on this system from here: https://support.lenovo.com/nz/en/solutions/lnvo-xpress

However it is failing to run, also fails in compatibility mode. The full error is below. I would like some opinions/advice on this issue as it seems likely to reoccur and if there is any suggestions on update of the system drivers, that would be helpful. I was also unable to get the command line update tool to run as there is similar error occurring to below.

Hi, I initially received error

Select "F1" to continue with logical drive(s) disabled
Select "F2" to accept data loss and to re-enable logical drive(s)

I pressed F2 and now starts to load Windows SBS 2011 and runs check disk and freezes at 13%, if I don't run Checkdisk it blue screens and restarts, won't start in safe mode.

I now have 1716-Slot 4 Drive Array Unrecoverable Media Errors, I have Looked in Configuration of Raid and the 3 drives are fine, 2 in Raid and 1 spare.

Version is 256MB, v5.06, If I can't get Windows to boot how do I upgrade the firmware ?

Purchased two new servers, not initially thinking of going with VMs & am wondering if there are any things I need to reconsider as far as hardware goes.
T430, This is going to be my Exchange server
Xeon E5-2620V4 / 2.1 GHz processor
64 GB Ram
2 - 300 GB - SAS 12Gb/s - RAID 1
4 - 2 TB - SATA 6Gb/s - RAID 5
T330, File & print, remote access,
Xeon E3-1220V5 / 3 GHz
40 GB Ram
2 - 300 GB - SAS 12Gb/s - RAID 1
3 - 2 TB - SATA 6Gb/s - RAID 5
Will these be suitable for running 2 VMs on each?
From what I've been reading, RAID 10 may have been a better choice, but, but not sure if that's for those unlimited pocketbook kind of environments!
Any suggestions greatly appreciated, as I find myself wondering if I need to change horses mid stream, here!

Hi People,

I'm currently running 2x Thecus NAS N-16000 Firmware 2.04.06a across two different Campus building.

Can anyone here please assist me how to assign the 4x Hot Spare disks that were replaced with new ones into the existing RAID60 group:
2
Into this degraded RAID group:

3Any help would be greatly appreciated.

It has already lost 4x HDD hence I notice they are all must be replaced manually on the physical slot and then manually added again to the RAID group as above, but I do not know how to do it and what's the risk ?

Thanks.

Lost a server yesterday that had a RAID 1 Mirror configuration on it.  Could not boot to the mirrored drive and don't understand why not.   I thought that if you replaced the failed drive and tell it to rebuild the array. New to working with RAID.  Replaced the original drive and still could not get it to boot and rebuild.  Had to rebuild the server from scratch.  What did I do wrong?

I have a HP8300 CMT that I want to add RAID 0 to.  It has a 500GB drive I have ordered a matching drive.  Do I have to enable RAID in Setup (BIOS SATA Emulation) before using Intel Rapid Storage Manager from Windows?  Can I avoid doing a full OS Install and just have the new disk come online as a mirrored copy?

I have read the manuals available online and it isn't clear.  I'm using Windows 7 Pro - 64

We're designing a storage setup for one of our new VMware ESXi hosts. It has a DELL Perc H730P hw RAID controller with 2GB cache and 8x 3.5" HDD bays.

We would like to maximise the host storage capacity and still retain the speed gain of a RAID 10 setup. We were thinking about installing 6x 8 or 6TB hard disks and 2x 256GB SSDs. We aren't looking to use SAS/Enterprise class disks or SSDs, rather something like a combination WD RED Pro's (or equivalent) and Samsung 850 Pro's solid state.

What would be the best way to utilize those SSDs in conjunction with the PERC card's own cache to squeeze out a maximum performance out of this system? Does that particular controller have something like the cachecade ability on the old H700 cards or an equivalent?

I has a Dell PowerEdge T710 which was originally purchased for a exchange server but was never used. I want to use it now to mirror the main server (also a PowerEdge T710) is has 2 hard drives RAID 1 for the OS and then a set off drives for the data RAID 5
One drive of set one (OS) and one of the RAID 5 or dead. Since I will only use this server for backing up and theses hard drives are very expensive [SCSI (SAS) RMP 15k] is there a way I could I just ignore the dead drives? (to my knowledge the RAID 1 yes but the RAID 5 one missing will kill the others)

I try to understand the process of recovery from RA!D1 vs RAID5 vs RAID10.    I am looking at 200GB storage space.  

Does all  discovery require to put the system offline for the recovery? If that is the case, why do I choose RAID10, RAID5 vs RAID1.

This drive needs to be replaced correct? Just want to make sure im correct.
The device, \Device\Harddisk2\DR2, has a bad block.

I have a DC controller running Windows 2008 R2 S1.   It is a raid 5 broken into a 40 Gb  C: (OS)  Partition and a D: (Data) Partition.   Lately the OS has been running very low on space.   Last week it was 1+ GB.  Today it said 530 MB open.   So I ran Disk Cleaner and it said that it would open 439 Mb of space.  After I rebooted there was only 620 MB open.  There is no one connected to the server since it is only a daytime running business.  But then as the evening progressed, there was less and less space.  I do believe some Windows Updates may have installed.  Now there is no space.  I read that I can run "dism.exe /online /cleanup-Image /spsuperseded".   Should I run this command?   Is there anything else I can do?  Should I try to uninstall those updates?

RAID stands for Redundant Array of Independent Disks.

RAID is data storage technology that allows multiple drives to be used together as a single virtual drive for reasons such as fault tolerance, reliability and performance.

There are several different levels of RAID that determine how the data is stored and the level of redundancy achieved across the drives.
