RAID

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 guys

I'm doing a document to prove that we need a cluster environment for our virtual machines, as we have only one IBM X650 M3 hosting a load of virtual machines at our datacentre. There is no SAN either. All of the disks being used are internal on the actual X3650 which I believe we have around 14disks. I'm about to find out what sort of RAID has been set up.

I am making the documentation simple for board/management, but wanted to include 'what's wrong with his scenario' to show the sort of problems that could go wrong.

The current X3650 M3 has dual power supply, so that can't be a reason. Storage though may be an issue as if more than two disks die, we would lose all virtual machines that are business critical.

What other possibilities are there? Faulty Ram? Motherboard dying? Faulty RAM?

Thanks for helping

My understand in write-through is that the controller puts the data directly to/from memory where as write-back lets the CPU do it. Is that correct?

   So neither method has anything to do with lost data due to a power outage? Only a cache backup (or a UPS) can save you there?

   So if you spend the bucks on a cache battery backup don't you still have the possibility of losing data that is in the cache of the hard drives?

Hi - hoping someone can help - We have a Dell Poweredge 110, RAID 1, Server 2012. We rebooted the server this morning and it came up with a message (see attached pic) about "Integrated RAID exception detected: Volume (HD1:079) is currently in a state DEGRADED - Enter the Dell 6gbps SAS Ctlr Configuration Utility to investigate!" First off, how do I get into the controller when it boots? Second, I'm going to pick up a 500gb HD, but need to know the best only way to install the drive (and to tell which one is degraded), is it hot-swappable? Do I just take out the hard drive and put the new one in? If I need to go back into the controller, do i need to add the hard drive there? I of course want to get this server back online without screwing up the RAID config. ANY help with this process would be appreciated!

Hi

Hoping someone can help in a hurry. Just taken on a server consolidation and found a failed disk this weekend.

I really need this to run production for a few more weeks while we are migrating to new kit. It is out of warranty and I can't quickly find an exact 1TB Enterprise SATA 7.2k drive to replace it with.

I have a 2TB Enterprise SATA 7.2k from a different manufacturer. Can I swap this with the failed disk and have it rebuild onto the new 2TB disk (I realize I lose space but that is not a concern)

Any issues or gotchas I should know about? normally I would prefer to mirror two two of the same (I would gone with a higher raid in the first place...) but if this get me out of trouble it will all go on a new storage array in a while.

During a render computer stopped responding and restarted. The RAID now refuses to mount.  Disk Utility sees it, won't
respond to requests to mount.

Is it possible to recover RAID-0?

I have an HP Microserver Gen8 which is failing to boot. It has an SSD boot drive (WIndows 10) and 4 SATA drives in the standard bays at the front.

I've got hold of an identical Microserver Gen8 and what I'd like to do is move all the drives across to this server which works fine. I've attached the SSD drive but haven't put in the SATA disks as yet. I've checked the BIOS and it can see the SSD drive, so that looks good.

The issue I have now is that the Gen8 server has a built-in RAID controller (Dynamic HP Smart Array B120i RAID support) and I'm pretty sure when I originally set it up, I didn't setup any RAID at the hardware level, so they were just a bunch of disks. In Windows 10, I used storage spaces with parity for software RAID.

So, my question is - can I put the SATA disks in the drive bays and boot up and it will see the drives / Windows Storage Space as normal or do I have to do anything in the HP provisioning beforehand? I remember that original server that fails to boot also uses the same B120i RAID controller).

I don't have a backup of the data that's on there and I can download it all again, but there's a lot of it (6TB), so I want to avoid having to do that.

I updated my ESXi from 5.1 to 6.5

I backed up all my VM's via Veeam Backup and Reoveray.

I detroyed my existing RAID set and re-created a new Virtual Disk.

I instaledl I upgraded my ESXi from 5.5 to 6.6licenses.

I instaled the OSMA

I'm just stuck on restoring my VM's.

I'm currently installing and deploying the new VCenter.

If anyone is awake, I could use some assistance in restoring the VM's from my Veeam Backup and Replication.

Thanks in advance for all the help.

I bought a refurbished dell r720 with 16 - 600Gb sas drives.  It came configured with one single RAID 5 volume.  What are some suggestions for volume and RAID level.  I plan on using as a Windows 2012r2 host for Hyper-V.

I have a server 2008 with a raid 5 that recently  SQL stopped working.

Checked the logs and found that one of the disks is failing (predictive failure) so I have another one coming and will replace. But in the mean time - scf /scannow is finding issues with the dll's in the common files\microsoft shared\ink directory.(which I assume is why some of the apps are having issues/not starting etc)

It states the hashes do not match the actual file - calling them corrupt. Not really knowing what they were I figured I could copy them from another server and just overwrite them. Wrong. They are in use. So tried booting into safe mode and running scf /scannow and got the same result.

I am timid of trying to repair windows for fear it will delete any data and or have to reinstall the programs/rebuild the server but even if it doesn't do that and would simply replace the dlls are it believes are corrupt - when I tried to boot off the Windows DVD - it couldn't determine the OS because it couldn't load the drivers for the drives (maybe because of the RAID controller hardware?) - so I was stuck there too. Normally we have to boot to the Dell System Management and Utility DVD if we are deploying the OS - not the Windows DVD itself - so I'm not sure what method I am to take here.

Any ideas?

Dear Experts,

I have two HPE DL380G9 servers, with the following drive configurations (identical on both servers):

9 SAS drives in Raid 5 with 2 Logical disks
another 9 SAS drives in Raid 5 with a single Logical disk
and another 3 SSD disks as raid 5

Both servers have 10GB NICs that are connected to a 10GB switch.
Both servers have ESXi 6.5 HPE optimized installed on them and have VSA installed on each one with a Fail Over Manager.
However, When I try to add the volume I configured on the VSA cluster, it appears as normal, degraded.

Some googling pointed out that It could be an issue with single pathing - I reconfigured the network to have 2 port groups on the 10GB vSwitch to enable multipathing for the ESXi and yet, even after rescanning, I still get normal, degraded.

Any ideas?

Hi All,
I recently setup a Dell Precision Tower Workstation with 2 X 4TB conventional hard drives RAID 1 managed by an Avago RAID controller. After 1 week of use, My client is not satisfied with the speed and wants SSDs and willing to pay for 2 x 4TB SSDs.

My thought to change to the SSDs on the Workstation is:
1. Clone the OS using Macrium, Acronis etc to a single 4TB SSD
2. Remove the conventional Hard Drives
3. Install the cloned 4TB SSD and the 2nd blank 4TB SSD
4. Boot the PC and let the RAID rebuild itself

Will this process work? Any foreseeable issues?

I have a Dell server running 2012R2. The server has 4 Virtual disks. The 2 I am asking about are just 0 and 1 which are setup using the same 2 physical hard drives. I did not set this up. The other virtual are 1 raid 10 with 2tb of storage and another raid 1 with 538GB of storage. The user added 2 additional 538GB hard drives which have not been activated yet. They want to expand the storage of the E:\ partition. I am trying to do this in the easiest but best recommended method possible. We will complete a full backup prior to doing anything. Should I create a new partition with the 2 new drives and just attach them via windows to the E:\ Partition? Because of how these 2 physical drives were split up I am not sure how to do this with the least amount of user interruption and/or downtime.

Virtual Disk 0 [ Raid 1] (Contains C:\ partition (80GB) and G:\ Partition (200GB)
 - Physical Disk 0:1:0 (538GB)
 - Physical Disk 0:1:1 (538GB)
Virtual Disk 1 [Raid 1] (Contains E:\ Partition (358GB)
 - Physical Disk 0:1:0 (538GB)

Guys,

I have a server with a asus sabertooth mobo that is giving me a raid critical error. Its saying at boot:

Problemis detected with array: 01 02
Critical status
A disk member of an array has failed or is not responding.

I understand what this is saying but when I go into the raid utility I cant find a way to get it to tell me which drive is failing. Also, it does show in the drive assignment the disk on port 01 is "single disk".

Asus has been no help.

Hi All,
I am setting up a new file server - Dell Precision Tower 7910 with Avago Controller. I created the RAID array but cannot find the driver to get the Windows installation to proceed. In other words, I am at the point of the installation where I need to provide the RAID driver for Windows to recognize the array/virtual drive and proceed.

I can reference the Download Page on Dell, but the Controller - LSI SAS3008 is available only as an executable.

Any help finding the controller is appreciated!

I haven't done an MS server installation since SBS2011 so am after a little advice for a client proposal.

Client is looking to migrate to a domain environment for management but is also looking to run some client applications on the server,

My understanding is that a Windows Server 2016 Standard is good for 16 Cores & supports installation on the   Physical  as well as 2 virtualised environments on the same hardware.

My thinking at the moment is a HP ML350P, Dual Processor Quad Core E5-2609, 64GB RAM. 4x 600GB SSD in Raid 5.

Setup the Server 2016 Host as the DC/ File Server
Setup 1st Virtualised Server 2016 as the application Server (Sage Construction, Paperless)
Setup 2nd Virtualised Server 2016 as a Terminal Server for remote sessions to the Application Server (this solution was suggested by application vendor.

They have approximately 15 users on site plus some remote users. It would be good to make the remote users more integrated into the office environment.

Wondering if I can get some feedback on the setup/hardware, tips/tricks, pitt falls.

Thanks

Raoul

Hello,

I have a Synology Diskstation 412+ NAS in my home office that is nearly full.  The NAS was purchased November of 2012 and has 4 Western Digital 2TB Red drives configured in RAID 6.  I am currently using 3.2 out of the 3.6 TB capacity (89%) and need to increase the capacity to 6-10 TB.

When I purchased the NAS it was being used for both work and home files. The work files involved backing up a web server,  a file server and 1 workstation while the home files included pictures and videos.  I decided to configure the drives in RAID6 so that I could weather up to two drive failures. In the past 5 years I had one drive go bad and the replacement was super easy with no data loss or downtime. I also have a new spare 2TB Red drive in a box in case another drive fails.

My work situation has changed and I no longer need to be able to handle two simultaneous disk failures. In order to keep my RAID 6 and increase my capacity, I think I have to replace all four drives.  If I was starting out today, I would rather have two 8TB drives mirrored and have a third 8TB drive available for a spare. I am looking for advice on the best way to expand my capacity while not breaking the bank.  FYI, I purchased a Western Digital 8TB EasyStore external drive that I will use to backup the NAS before I make any changes. I currently backup my NAS volumes to multiple smaller drives.

Here are the options I am considering:

1. Reconfigure current 4x2TB system to RAID 5 increasing …

Hello,

I've arrived at a scenario where I want (need) to add more space to my HP Proliant DL380 G7 running Windows SBS 2017 R2 server and I read a lot about the MSA range and managed to pick up a cheap(ish ex demo-no drives) HPE MSA 1040 SFF Dual Controller Storage Array... but this is my first 'Storage Array rodeo', so before I purchase / configure any drives... I was going to ask the community here about some pros and cons and best practices.

Please let me know your thoughts about how I could achieve a best performing throughput and data integrity connection between my server and this storage array, whether or not that's a good idea to connect directly via iSCSI,  or should I access the MSA via a swtich?!  because I was thinking iSCSI looks more robust, but is that actually the theory?!

I was hoping to get some performance, so was hoping to achieve a RAID1+0 to achieve 2.4TBs in this storage array via 8 x 600GB 15k SAS 12G DP 2.5" drives.

So, any do's and dont's would be greatly appreciated.


Thank you very much,

I am setting up a new server to host a Windows 2012r2 Hyper-V VM.  The virtual machine will primarily be a 2012 SQL server.  What RAID level on the new host server would be recommended?

I'm getting intermittently high CPU usage on Win2k8r2 Standard server.  just a little while ago I wasn't even able to rdp in.  my main issue is that we have Symantec Backup Exec on this server and the jobs are failing or going really slow most likely due to this high CPU usage.  At times it would be at 90 - 100%.  

About this physical server:
Dell PowerEdge 6950
The C: drive is in a Raid-1 configuration and is either SAS or SATA drives.  
Dual-Core AMD Opteron Processor 8218 2.59 GHz (2 processors)
12 GB RAM, 64-bit OS
Raid controllers: two Perc 5/1 Adapters and two Perc H800 Adapters (all attached to 4 Quantum tape drives)

I'm thinking that this may be a hard drive issue.  Or it could be a driver issue with the RAID controllers.  What is the best way I can go about diagnosing the hard drives on a server?  I've already contacted Symantec and Quantum and I don't believe it is their issue. Quantum firmware and drivers are completely updated to latest version.  Any other feedback would be helpful?

This is really starting to do my head in.
My DL380 G6 has 3x RAID controllers.
  • 1x P410i with 256MB cache (no battery).
  • 1x P212 with 256MB cache (no battery).
  • 1x P800 with 512 BBWC

The P410i came with firmware version 5.70
P212 with v 3.xx
P800 is still v7.xx

The P410i links to the main cage in the server, the P212 to a generic SAS/SATA drive unit and the P800 to a MSA60.

The main reason for the firmware updates on the P410i and P212 was the P212 couldn't see 3TB+ disks.
Since the upgrade, the P410i has 0x14 lockups (1719-Slot 0 Drive Array - A controller failure event occurred prior to this power-up. (Previous lock up code = 0x14)) in ESXi, however seems fine in SmartStart and a Linux live boot (which I used to update the firmware from).
ESXi starts up and loads fine when the P410i has it's drives out, obviously not loading the VMs on it. (1x 4x146GB SAS as RAID 10, 1x 4x500GB SATA as RAID10).

In desperation I took the server home to try to at least recover the data off and on my workbench (with the P212 and P800 connections off) it booted fine. I began a very cumbersome backup overnight with SCP and at 500KBps it didn't get very far.
As it ran well, I took it back and plugged it in at the datacentre and I'm back to square 1.

Does anyone have any ideas what I can do or what to try? Since ESXi tries to access the datastores off P410i it jams a SSH session when …

I pretty new at RAID and adding additional Hard Drives.


As it stands, I have a Dell PowerEdge r720 with 5 x 900gb Hard Drives installed on a Perk H710 Raid Controller.
With a Raid 1 + Raid 5  according to the initial notes I have.

Right now I'm only showing on my VMware ESXi, 5.1.0 Capacity 1.64 TB with 135.07 GB free.

I want to add 2 more 900gb hard drives.  How can I go about this?
