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.

Hello - I have a server PER710 that I will use for a FTP server. I have c drive set on a RAID 1 and I'd like to have my FTP dir on my DELL Compellent SC220. How would I create a volume on Compellent and have it recognized on PER710 Server?

Thanks,

I have a client with 2 Dell T630 Servers (practically identical boxes purchased about 6 months apart). One runs Server 2012 R2 Standard, the other Server 2016 Standard. Both run Hyper-V. Each box hosts one VM (VHDX files).

I have multiple backups of the 2012 Server (Altaro VM backups, Macrium backups of the physical box, and I’d also make direct copies of the VHDX files as well before proceeding).

The 2016 box hosts a VM with Server 2016 Standard acting as a Domain Controller. The 2012 box hosts a VM running Server 2012 Standard joined to the domain. It is not a secondary DC, etc. – it is only a member Server that runs a database program that multiple users access.

Note - the host boxes are not joined to the Domain – just the VMs are Domain members.

The 2012 R2 box has a hardware RAID 1 array for the OS (Dell Perc H730p Controller). Storage Spaces handles the Hyper-V VM files. The Storage Pool was created as a mirror using 4 Samsung PM863a SSDs.

I needed to add space to the pool. Added 2 more PM863a drives to the Pool. The problem is that 2012 R2 Hyper-V cannot optimize the storage space used, so the 4 original drives are ‘full’ (i.e., they show as being 99% full) and the 2 new drives are practically empty. As I understand it, the 2 new drives will get allocated any new storage as needed.

I’d like to take advantage of the new features of 2016 Hyper-V (one of which is the ability to optimize the storage pool). My question is how to best accomplish the …

Hello, so my 4 drive hardware backplane or RAID card is experiencing a failure, two ports are malfunctioning which caused the RAID to go in degraded state and cause a passthrough disk to fail.  SeaTools didn't find anything wrong with the drive, so I narrowed it down to either the RAID card, the cables, or the backplane, so yeah, rather than spend a lot of time with trial and error, I thought it might be worthwhile to replace all 3 components and try a different setup.

My existing Hyper-V setup involves two RAID arrays on separate cards, a RAID-5 (Areca ARC-1210) and a RAID-1 (Areca ARC-1200).  Both arrays are using Seagate Constellation drives.  The hypervisor boot drive is a standalone disk.  The RAID-1 is used for boot VHDs and RAID-5 used for Data VHDs.  So what I am looking at is replacing my current Areca ARC-1210 with an ARC-1220 which would get me 8 ports.  This would be enough to setup two RAID-5 arrays on the card and then I could stripe them in Windows Disk Management for RAID50.  I already have the six hard drives needed for this.

Let me be clear this is not a production environment, this is just a home lab.  Are there any pitfalls to look out for using RAID-50 with VHDs besides losing two drives on one array?  I don't have enough slots in the case to do RAID-60 and RAID-10 would leave me short on disk space.

I'm installing a Dell PowerEdge R730 Server with 6 units of 2TB SAS drives on PERC H730 Mini controller. I created RAID-1 with 2 drives and installed Win2016 successfully on it. On the remaining 4 drives I created a RAID-5 virtual disk which came to about 6TB. When I boot to windows and go to Disk Management, I  see the 6TB RAID-5 volume split into 2 volumes of 2TB and 4TB respectively. The 2TB can be allocated but the 4TB is grayed out and can't be allocated. The boot is set to UEFI. I need to access the 6TB virual drive as a whole volume with NTFS, kindly advise

Hello -

I have swapped out bays 0 and 1 with SSD Drives (850 EVO) and using existing drives 2, 3 4, and 5. I am in the process of setting up RAID on the server. I selected Ctrl + R, got into RAID config screen, selected disk group/controller and pressed F2. I was able to create new VD. I selected RAID 1 and selected all availiable disk I want into RAID 1 (0 &1). All looks like it accepted the change, however I have Disk 2, 3, 4, 5 that I'd like to put into a RAID 10. I cannot select F2 on those drives. It is not letting me configure a new device group. I do not wan to proceed in installing my OS Server 2012 and not have the remainder of disk setup in a RAID. ANy reason why this is not allowing me to setup?

Thanks,

I have seen scattered info but nothing definitive and that has step-by-step instructions.  The obvious hurdles are:
-How do you install Windows when it won't recognize the RAID Array in the Windows installation?
-Can you partition a C: drive at 100GB and a D: drive at 3.9TB? If so how?

I want to get an optiplex - 3050? 5050? to use as a 'server' in a workgroup running win 10. I want that machine to have RAID 1 (enabled in the bios / running intel matrix storage software) I don't see dell offering that setting on their website as you build the machine to buy it.  So the 2 drives you include are JBOD.

I'll have to image the hard drive, configure the array in bios then restore the image?

is there a way to get them to build it as raid 1? or is that a sign that the machines don't support hardware raid?

I do see this page:  http://www.dell.com/support/article/us/en/rc1133626/sln155274/how-to-configure-raid-on-a-dell-desktop-pc?lang=en

that says most desktops can do this... and then tell you how to do it yourself.  vague.

Dear All,

I have some business pc Optiplex 9020 with OS Win8.1 .My issue is that with raid the pc takes a long time to boot from 40 minutes to 2 hours.Also when we i tried to update some software in the workstation it took many hours and in some pc it fails.
I would like to ask if you have any similar problem with this type of pc and how you have resolve it .

I have a Perc 5/i installed on a PowerEdge 1900.  I have four 750gb hard drives that are in a RAID5, potentially.  The Virtual Disk was initialized and when I just hit the Enter key on Controller 0 I am told:

Configuration is not allowed!
ERROR Code: Unknown

There are no errors outputted on the tiny screen.  Yesterday it told me that the ROMB battery was dead, so I replaced that, and now no more errors.  However, there is this problem now.

I have an old PowerEdge 1900 that has a Perc 5/i in it.  I go into the configuration utility and select RAID5 for setup.  I have 4 750gb hard drives, so it comes out to 2.2 tb, or close to it.  I initialize the disk and when that is done I step through the rest of the process and on the last page I select "APPLY" then CTRL+ALT+DEL to reboot.  Upon rebooting there is a message that says "All of the disks from your previous configuration are gone".  It tells me that there are 0 logical drives on the host adapter, and obviously, 0 logical drives handled by BIOS.  What is the issue?

Hello -

I have a DELL PE R710 and it currently has 6 HARD DRIVE, 146G, SERIAL ATTACHED SCSI, DU, 15K, 3.5, SEAGATE, HUR and a PERC H700 Integrated RAID Cont roller, 512MB Cache, x6. I would like to use two Samsung SSD 850 EVO (Model: 75E120) as a RAID 1 (OS), and 4 more drives as a RAID 10 (DATA FTP). My question is if I replace my existing drives, what hardware will I need to convert the server drive bays and will this work with my existing PERC? Will it recognize new drive and speed capabilities?

Thank you so much!

I have installed Server 2012 R2 and created 2 VMs (VM-1 a DC and VM-2 a member computer) both running Server 2012 R2. The test bed server I am using has 2-120 GB SATA SSD for the OS in a RAID 1 and 2-1 TB SATA hard drives in a separate RAID 1 configuration for the data storage. They are controlled by the Dell PERC card. I would like for the member computer, VM-2 to be able to access the data volume and see it as just another hard drive with a drive letter. This is a work in progress for me as I am learning and reading articles on how to do this. As a side note when I created the Hyper V folder (300GB) to hold the VM files, I was able to see the data volume from the Hyper V host and located the Hyper V folder there. I was not sure of how much space the VM files would require as the system space requirements grow. I would have preferred to locate them on the SSD...however.
On the member server VM-2, SQL Express, RDS and a business management application will be installed. It should have about 500GB available. All of this will be required to be backed up nightly. Your help and comments are appreciated.
Thanks - HBee3

Have a desktop, Dell XPS Studio, that came with 2 1TB hard drives set up as Raid 0. One of them is now failing & it won't boot, get the error message "AHCI Port0 Device Error Press F2 to Continue". F2 brings you to the BIOS setup and it's just stuck in that loop.
The client said it boots up every now and then but i've tried it at least 20 times & no joy so reckon it's after getting worse.
Any way of extracting the files from this as they've no backup?

I was building a small-time home-brew server today from parts laying around and I have a build that is practically brand new. Never used but once or twice. But everytime it powers down, I have to reset CMOS for it to power back up. Aside from that, it works well. I can soft and hard restart it. my RAID array is fine. But if I power it down, I need to reset the CMOS to start it back up.

Any ideas as to why this happens?

I'm trying )remotely) to help a client check things on a RAID cotroller

I have downloaded the Intel RST Raid Ctrl sofwtare from here http://support.lenovo.com/us/en/downloads/ds041872 but it only shows me the CDRom disk

Is there a sofwtare that can display the RAID config under Windows Server 2012? or do I need to boot into the RAID controller?

Hi,
 
 I have HP DL360 G5 server with P400 SAS RAID Controller with five 147GB hard drives. It is running VMWare ESXI 5.1. One of the hard drives failed and it showed in amber color. I replaced the bad hard drive in timely manner, but I like to be able to monitor RAID status in a graphical fashion. Beside the VMWare box did not even beep when the hard drive failed.
 In VMWare box, I have several VMs - Windows 2008, Windows 2003 and XP desktop IS.
 I can also utilize a separate workstation PC (running Windows 7 or 10) to run RAID management software if necessary.
 Can you guide me into the right direction?

Thanks.

I have a HP Gen6 server with a P410i controller. ESXi is giving me the following warning:

We also notice the performance of our server is slower and the backups seem to often fail.

I could not find any errors in the ILO. Does this mean I just need to replace the battery of the controller?

Hello Experts,

Does anyone know the procedure for backing up the Raid module configuration on a Dell MD3260?  We are replacing the Raid module controller battery and have it listed in the steps to save a copy of the configuration file in the MD Management console but it does not have any further instruction.

Thank you,

hi,

bought new LARGE SSD and after adding new LARGE SSD Disk to windows 10, I can't expand the volume from disk administrator.

I use LSI raid card and I follow the support staff's instruction on expanding the SSD volumn to the level I want, and then in Windows 10 disk administrator, I see the new volume but it seems i can't make use of it?

anything I can do to make the volume circled become one volumn ?

tks. you can see that there are option for c:\, marke partition as active, should I choose that?

and I checked this one and I am not sure if I should use this:

My SCO Unix RAID 5 server have 3 HDD. Today 1st and 2nd HDD failed only 3rd HDD showing ONLINE. Is there any chance of data recovery if i install new HDD in 1 and rebuild and then the 2nd HDD and rebuild.
Is there any chance of data recovery.

I typically configured my spinning hard drives for the OS and Data files as Raid 1. If something happened then I just swapped out the drive and kept working.

When I got the SSD drive for the OS I could only afford the one drive. Now the prices have come down and I was thinking of again using Raid 1, for availability.

Talking with Samsung Tech Support they said that it would work but that they don't recommend it due to the fact that it would shorten the life of the SSD.

Having just had the drive fail and while waiting for the replacement I am thinking of getting my system up with a new SSD and when the replacement ships putting it in a Raid 1 set.

Recommendations?

Thanks,

Steve
