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.

2018-03-19-16.28.46.jpgHi experts

I have old server HP Proliant ML150 G5, 32 GB RAM, 2 hot plug cages, each with 4 drives. I would like to create UNRAID server, but I know that limiation of SmartArray controller E200 is  inability to work in HBA (JBOD/IT) mode. I.e. I would have to create for each drive Array0 - this is stupid in case of recovery, SMART indication not being transferred into UNRAID, need to reboot computer in case of failure. Also this card is able only to handle 2 TB disks at max.

Is there RAID card which I can buy for that server which can use with current cages? there are some prehistorical cablings used there, I will make a photo.

Many thanks for your advices

Got a problem with an old server I was hoping to do a simple P2V on and would appreciate some advice on physical mirrored disc issue.  I normally deal with proper systems with RAID controllers, SAN connected storage etc. so an OS software based mirrored drive is thankfully not something I have had to deal with since hardware has been available to do the job...

This server had been there on a site for many years (alongside a Windows 2000 SBS and Windows 2003 SBS on different LAN's) all of which I have been working to migrate their users off.  This was running a system for their CAD users that has now been replaced with a new version but the old system needs to be kept for reference purposes, I am loathe to even reboot it at the moment while errors show with the mirrored drives, I have tried running a P2V using Disk2VHD and had a non bootable result and backups are basically non existent.  I will get a file level backup of the data files and kicked off native NTBackup but considering the P2V output I am not convinced of any other backups until I can restore them of course.

Windows 2003 R2 SP2 on physical HP server.  Appears to be have 2 x Adaptec SCSI cards and 2 x 136GB SCSI discs using software mirroring.

Disk 0: 136Gb drive partitioned to C: and D: with small 31Mb partition before C:  Dynamics disc, Status: Online (Errors)
Disk 1: 136Gb drive partitioned to C: and D: Dynamics disc, Status: Online (Errors)

In Disk manager both drives show Online (Errors) and both…
Have an old 2950 dell server and it has gone done, the raid error is reading -Raid Status offline. Would like to know if there is any way of bringing the system back online. below are screen shots. Thank you.

Server: HP ProLiant DL360e Generation 8
RAID Controller: Dynamic Smart Array B320i RAID Controller
RAID Configuration: RAID-1 (2x1TB drives)

Ubuntu 16.04 <or> Ubuntu 14.04

Hi All,
I am trying to install Ubuntu Server on the HP ProLiant, but even thought I set up the RAID configuration during the Pre-boot, the Ubuntu setup does not show that any drives are detected.  *See attached screenshot*.
I will also note that I am NOT a Linux guy.  But in the Windows world, if you can't see the drives it's because the driver for the RAID controller is missing.  The fix is getting the driver from the manufacturer website, put it on a USB, and boom.  But I'm having difficulty trying to determine if that's the exact issue and how to obtain the right drivers for Linux.  Am I even on the right track?

Any help would be greatly appreciated!
I've been having a hard time with this for several days, hoping someone can help me with this.  

Here's the setup; got some Optane P4800X PCIe drives and I want to RAID the boot drive in Server 2016 for resiliency.   From what I understand hardware RAIDing PCIe drives simply doesn't exist yet, so we're stuck with software RAID.  Here's where it gets fun.  

I can RAID 1 the C: volume just fine.  That's all dandy.  But when I remove the primary plex, the secondary doesn't boot.  I have tried all sorts of methods to get the secondary drive bootable, including;

  • DISKPART and XCOPY the EFI and Recovery partitions from the main drive- no dice, BCD error
  • This
  • handy document was looking promising, but when trying to rebuild the secondary BCD we have no ramdisk entry in Server 2016, so that ended up a bust.
  • Fresh install of Server 2016 to establish a good Recovery and EFI partition, then delete the OS partition and replace it with a mirror- no dice, BCD error

All the fun of this points back to the BCD.  Problem is, I can't edit the BCD in recovery mode since the disk is showing up as foreign because it's dynamic (required to do MS mirroring).  If I import it, it instantly becomes unbootable.  Bootrec /scanos
I need to upgrade my HDD's for my physical server due to space restrictions on the original HDD's.  It is running Server 2008 R2 Standard and the Raid Controller is a PERC H710.  Is it possible to do this by simply removing one HDD at a time, letting the VD rebuild until all of the HDD's have been replaced and then expanding the VD?
My Dell Poweredge R720 uses the PERC H710P Mini BIOS config utility 4.03-0002 and has been running RHEL 6 on a RAID1 array (Made up of 2 3TB WD SAS HDs). I installed 2 more SATA drives today as a separate RAID1 array (With the intent of using dd to clone my older drivers to these new drives), and now RHEL6 on my original RAID array won't boot. In the RAID utility, they show up as unconfigured physical disks, and my new ones show up as the new virtual disk 0. I couldn't see anywhere to tell the utility that I still need my old drives to be the primary virtual disk/boot device... Thanks in advance for your time.
I imagine encrypting server drives would slow down RAID. But what happens if a drive fails and needs to be replaced?
Will the encryption allow hard drive replacement?
Are there any other problems with encrypting Windows servers?
In a RAID(5+3), 300 IOPS are being processed, and in RAID5(7+1), 600 IOPS are being processed. If the disk on each RAID is damaged, in which RAID will there be a greater effect on I/O?

Hi all,

I have an Inspiron All-In-One 7459. Every time I boot up, I receive Error: 2000-0723 Hard Drive Alert, visit I can boot into windows and everything seems to be OK but have also noticed issues with the 30Gb Partition SSD drive which (cache drive) that there are issues with this when I boot into windows.

After reading forums and other posts on this issue and even speaking with Dell support chat, I am getting no where quickly in resolving this issue. Dell support suggested downloading the OEM operating system and reinstalling, which I did but this doesn't seem to clear the error on startup. I even did a full recovery on a brand  new hard drive, which still had the same errors.

Thinking that all the forums suggested that it could be the partition, I thought I would install my other laptop Hard drive into the Inspiron. After installing my (working & close to brand new) Hard Drive, I still receive the error: 2000-0723 Hard Drive Alert, every time I boot which tells me that it couldn't be the hard drive and has something to do with either BIOS, Dell Support Assist or the RAID function that is built in for the cache drive?

I have updated BIOS to version 1.7.1, reset the BIOS back to factory default. Disabled Support Assist in Bios. disabled Fast Boot within Windows 10.

There is no issue with the physical hard drive as I have tried 3 HDD's now (1 being brand new) so I would like to just clear this alert when I boot.

Any help would be …
Hi guys,

I had a server that suffered a power outage and when it came it back on the fan just stays at 100% and it doesnt boot, i would like to get some data from this server, its a HP ML310 G%, the disks i imagine are absolutely fine, its just booting up the server.

I have a G$ would i be able to put the disks into that or even swap out motherboard?
Its basically end result - Unusable Drive space.

I have a Dell R610 with 6 bays. I grabbed 6 - 600GB 10k drives to be put into a RAID5. I installed the drives - went into the RAID controller utility - selected all in a RAID 5 - no problem. Put in my Dell Systems Management bootable DVD - selected Server 2008 R2 SP1 and ran it. It finished - asked for the 2008 R2 SP1 media. I put that in and it brought up the Windows install that we all know so well. Everything going great until I got to where to install the OS. I had two choices (Both showing Disk 0 unallocated). One was 2048GB and the other 748GB. Truth be told - I wanted to have 1 entry so I could carve out a 100 or 200GB OS partition and install there. After trying to figure out why it was doing that I gave up and tried to choose the 748 allocation since the data I need to put on this server is a little under 2TB. I was welcomed with an error: Windows is unable to install to the selected location: 0x80300024. Fine. I give up. I'll choose the 2048GB entry and click New and choose 100GB of it to install Windows. I allowed it to complete and when the OS was up - it only showed the 100GB C drive so - I went into Disk Management. I right clicked on the first (1948GB) black uninitialized space and created a simple volume. Good. Next tried the 748. No options are available in the 748 selection.

What I was trying to accomplish was a single VD - RAID 5 config with a 200GB OS and rest to a single Data volume. I tried …
Building a Windows File Server

My CEO wants to build a file server, currently we have a 3TB with RAID 5 on a old dell server win 2008, we really want a faster server with larger space etc.

any recommendations
Dear All,

I am unable to install Windows server 2012 r2 std on HP ML 310 g8  server .
i configured Raid  1   through Intelligent Provisioning. installing time after copy 99% i am getting error "The wim.xml  file was not generated correctly. this may have resulted from a failed file copy of install.wim.
Hello There,
I have Server DELL POWER EDGE T620 IT HAS RAID 6 AND WORK very will.
 I need create mirror for this Array Raid 6.
So i poet this steps :
1. I will buy The new H.D The same size and the same type .
2. i will take out the old hard drives out the server, that already has OS system and
     Application    and data.
3. i will BUT THE NEW HARD Drives on the server, then i will   build the same RAID .
 When i finch build the array RAID for the new hard drives i need retainer the old H.D to the same Server , this time the Server it has the old hard drive and the new drive,
NOT:  a)the old hard drive It has (windows SERVER 2008 R2, AND APPLICATIONS , and data)
     b)The new H.D  it has the ARRAY
2)IF THE server run the window shod see the virtual HARD DRIVES AS UN LOCATE SPAS?
code i create mirror on this vertical  hard drive ?
All i need just i need the new shards as backups for server any time the system crache      

please can you help me ?
When I open Dell OpenManage Server Administrator, it is correctly showing the inventory of the server, except for the physical and virtual disks on the machine. Instead, it is showing me the physical and virtual disks and RAID-5 array on a DIFFERENT machine. I have tried opening OMSA with localhost, the IP of this machine and its name, I have checked that NSlookup is only reporting the IP of this machine. Is there some way to force it to check the inventory again? I have uninstalled and reinstalled twice now.

I wondered if anyone out there has ever successfully added a Dell MD1200 attached storage device to an existing PowerEdge host running Hyper-V Server 2012.  As it’s Hyper-V Server, there’s no GUI, so OpenManage isn’t obviously an option.

Currently looking at accessing the basic ACU at boot, but struggling with this also.

Does anyone have any thoughts, or ideas?
We are building a 3 Host ESXi Cluster and are looking at the HP MSA 2052 Array with the Automatic Tiering. We were looking at populating it with the Following Drives
2x400GB SSD RAID 1  - Performance Tiering to 15K
2x400GB SSD RAID 1  - Performance Tiering to 10K
1x400GB SD Global Hot Spare
6x1.8TB 10K  RAID 6
13x600GB 15K RAID 6

1x1.8TB 10K Cold Spare
1x600GB 15K Cold Spare
All would be combined into One Drive Pool. (or?)

There will be 9 VMs at the Start and up to 26 VMs later. We would add a Drive expansion Chassis to the MSA at that point.

On Datastore Creation, does it matter if you create one Datastore or multiple Datastores if they are all coming form the same Drive Pool and all three hosts are part of the same Cluster and will be responsible for the same set of VMs?

Its about 12TB of storage if you don’t include the (2) 2x400 RAID 1 (if they are used really only for Movement of Data vs actual Storage?

Just in terms of ESXi, is there any Benefit to have multiple Datastores mounted from the Same Drive Pool?  Or should we have one LUN, vs 3 LUNs from the same Drive Pool?

New TS-412 raid 5 with 4x2tb enterprise drives. Initialization went well, even started installing some apps. about 24 hours in drive 1 reported some errors, I replaced the drive, it came up and the errors were gone. Now I am in degraded state with all 4 drives being seen but the raid reports 3/4/5 online and that I need t install a drive in port 1. Volume manager shows all 4 drives up and good and ready. However logical volume in degraded state file system ext 4. Raid management also shows in degraded state,  however I can do nothing from that page.
Hi All,

What could be best option for viewing RAID configurations in x3635 m3 / m4 , x3400m2
I have a windows 2012 server that is running out of space on the F drive, I see that I have 185Gb unused in computer manager and was hoping to extend the volume.
As you can see from the picture, this is grayed out. How can I extend the volume ?
This is running on 6 x 600Gb SAS on a raid 5, 1 of the drives is spare.

I have a 2012 R2, Proliant 380 G7 with an NC522SFP server adapter connected via 2 DACs to an MSA 1040 SFF, but I'm wondering why I can't see any Host Ports 'discovered' in SMU v3

Ps. This is a second-hand unit, and it appears there is some settings that still linger from the previous owner, so I am not sure if it could be a firewall port blockage or what is going on, I'm in fairly unfamiliar territory with this MSA.HostPorts.jpg
I'm trying to figure out the best solution for my current home setup. I have 5 3tb drives, ASRock Z97 Extreme 6 mobo and Vantec 4-Channel 6-Port  pci-e card (only 4 ports at once).

I had 3 of the drives in raid 5, but was running out of space so I got the additional 2 drives. My top priority is the space. I know Raid 10 is the typical route to go, but I don't want to give up the space. The ASRock has 6 onboard Intel ports so I currently have the drives installed there. I set it up with Raid 5 and was getting horrible performance. The speed tests were good, but actually moving files to the drive was getting around 40mbs. I did not write zeros to the drives before hand so I'm doing that now hoping that is the issue. I've tested each drive individually and they are good.  

Can I get some suggestions as to how you guys would make the best use of this setup. My priorities are first space, then speed and then redundancy.

I appreciate the help!
I have Dell Power Edge 2950, configure RAID 1 with 2 Driver of 2 TB, One Drive show amber light so i replace the drive, when restart it  show foreign config, i clear foreign config,  System boot and working, but 2 drive only one green light blinking.  i restart and press CTR_R and see the one drive online and 2nd missing, while press F2 no option enable, only start blinking option available.
while Press CTR+N to next page 2nd drive is ready but not online, no option enable to online the drive.
kindly suggest me how to online the 2nd drive for RAID 1 working, i cannot clear config, because of my Data.



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.
