Storage Hardware





Storage devices include any device used for storing and retrieving digital information. Hard disk drives (HDDs) use one or more rigid ("hard") rapidly rotating disks (platters) coated with magnetic material. Data is accessed in a random-access manner, meaning that individual blocks of data can be stored or retrieved in any order and not only sequentially. The primary competing technology for secondary storage is flash memory in the form of solid-state drives (SSDs), but HDDs remain the dominant medium for secondary storage due to advantages in price per bit and per-device recording capacity. CD-RW (Compact Disc-ReWritable) is a digital optical disc storage format that allows information to be stored outside the mechanical HDD.

I am running a Dell T110 ii server with a PERC S100 controller, in what I am told is RAID 5, I am remote from the site so I cant confirm that it is defiantly RAID 5

We had a problem a few days ago when I saw the following errors in Dells Open Manager

Disk medium error detected: Physical Disk 0:1 Controller 0, Connector 0
Redundancy lost: Virtual Disk 1 (Virtual Disk 1) Controller 0 (PERC S100)
There is an unrecoverable medium error detected on virtual disk: Virtual Disk 1 (Virtual Disk 1) Controller 0 (PERC S100)

Disk 0:2 was Offline, and the Virtual disk was showing Degraded

I set disk 0:2 as Hot spare and it started to Rebuild the Virtual drive, which failed after 7 or 8%

I now have all 3 disks online but the Virtual disk is showing as Failed, the only option it gives me is Delete, which I am hesitant of doing, any pointers on what to do next, I don't know the condition of the drives apart from they say they are online

Disk 0:2 was offline but Disk 0:1 had the error?

I picked up 4 HGST Ultrastar He8 drives recently (HUH728080ALE604) and was going to put them on a LSI 9268-8i card.  Another EE expert indicated that might not be the best move.

I've looked at the current lineup of the LSI model line and don't need the 12MB/s capability.  Which of their 6MB/s RAID HBA adapter cards could handle these drives?  Looking for internal drive configuration that would support RAID 6.


EDITED Update:
It appears I am looking for the drivers for the Raid controller for the HP server for Server 2012 Stadard R2.
HP dl360p Gen8
p420i is the controller.

-Original post-
Need to find where these drivers are located.
New Seagate 12G, 10k, 900gig, SAS drives.
Almost new server and RAID was set up on these drives from the server array utility just fine.
Installing Server2012 Standard R2 requires the drivers.

Anyone know where they can be obtained?
Hello, I was wondering if I could get some feedback/suggestions regarding a failed RAID hard drive.  I'm helping an office and they have the following configuration:

HP ML350 G6
Smart Array P410i controller
1 Array/ 1 Logical Drive - 6 TB
Drive configuration: 8 drives.  Bay's 1 - 8 have: HP 1 TB drives inserted

The drive in Bay 7 has recently failed (Red amber light).  The office believes the drive in Bay 8 was configured as a "hot spare" and automatically rebuilt (I see activity/green blinking light on the drive) when Bay 7 failed.

A replacement HP drive (same part #/size) has been ordered.   This is a production environment so I can't shutdown/reboot the server until this weekend.

Can I just insert the replacement drive into Bay 7 while the server is running?
Will the RAID controller automatically configure Bay 7 as the "hot spare"
Will the RAID Controller keep Bay 8 as an "active" drive in the array

Based upon the info provided, I'm basically trying to determine

1) What's the "best practice" on how/when to add the replacement drive into Bay 7
2) What actions will automatically happen when the replacement drive is inserted into Bay 7 (What would the RAID controller do?)
3) Do I need to reboot the server and make changes in P410i ORAC to get a similar setup as before (seven "active" drives in the array and one hot spare)

Thank you

Thank you

I have a LSI 9260-8i HBA controller with a 3 drive RAID 6 configuration.  I'd like to add a 4th drive to it.  I've read the docs but am not sure how the controller behaves exactly.  Does it bring in the new drive in the background while the array is in use, or do you have to wait until the process is complete through the card's BIOS UI?  That could take a while with 3-4TB of data on the current set.


In the old days, they called this a headless PC.

My Mac video card died aND  one option is to use the Mac or my Time Machine drives as a way to access this information.

I assume the external backup drives I can just plug in.

How do I do this with the MacBook as an external drive?

I need to collect the contents of the hard drives directory listings for 50 computers for an audit and then be able to report (as an example) what Excel spreadsheets are stored on each computer.  Or what PST files are stored on the laptops?

Obviously, I can export a directory listing, but this is not ready for importing to a database/analyse tool - so are there any tools out there that could help with this?
Long story short, I have no idea how to externally connect to a 128G,M.2,2280,PCIe3x4,SAMSG,STD Solid State Drive outside my computer like I would a SATA drive. I need to clone my current drive, which is shown below.
Please provide me with URL hyperlinks of where I can purchase high quality USB to M.2 SATA hard drive adapters so I can connect M.2 SATA hard drives to other computers using USB cables.

I have already tried using the adapters listed in the URL hyperlinks below but these adapters haven't worked.

I don't mind paying more for adapters that work.

Where can I purchase these types of high quality adapters from?

These are the adapters that are too cheap and don't work (I should have read the reviews before purchasing them):


Hard Drive BayHi,

 I have CHENBRO 2U  Rackmount Server Box with six hot-swap 3.5" 600GB SAS hard drives (as seen in the picture).
 Whenever there is a hard drive failure in the past, I have been taking out a bad hard drive tray out of the server, unscrew hard drive from the tray, put a new hard drive into the tray, put the screws on the hard drive tray and pop the tray back into the hot-swap bay on the server.
 Now I just like to have a hard drive in tray ready to go so that I can cut down the time it takes to put the new hard drive in to the server.

 Having said that, here is the product specs:

  Can I buy a generic 3.5" hot-swap try or have to purchase CHENBRO made hot-swap try?
  As seen in actual picture of the server, there is a light in front of each hard drive tray.  

What does it mean to be "Always On"?

Im new to Nimble Storage Arrays, my previous experiences have been with NetApp arrays.

Im looking at ways of using Storage level replication to move data across two widely separated Nimble CS Arrays.
The two devices are 1000 miles apart and have a mean latency of 90ms between them.

We are using VMWare as the hypervisor layer and Veeam as the backup solution. Veeam is also being used to replicate some key VMs across the two sites.
The RPO/RTO is very loose, with a days data loss and two days recovery of key services deemed acceptable by the business.
Obviously, I would like to be better than that.

As we have Nimble CS Arrays on both ends, it seems like we should be using the Storage Level replication to move the data we wish to protect, rather than using Veeam further up the stack.

There is a good, stable VPN tunnel between the two sites, but the tunnel needs to prioritise business application traffic during work hours.
After hours, there is little traffic across the tunnel so it can be used for replication.
The link speed is 12mbps, with a peak of 24mbps.

My questions is informational gathering.

Is it possible to use Storage Level replication across a 90ms latency WAN?
What are the advantages/disadvantages of using Storage Level replication instead of Veeam replication?
Does Storage level replication reduce the amount of traffic sent across the WAN as compared to Veeam replication?
Anything else I should know?

We have so called server - Dell OptiPlex with Windows 10 Pro x64. it came with Windows 7 Pro x64 and an upgrade was done a while ago and now we are on the latest built of Windows 10. We have two 500GB hard disks configured through Disk Management  as mirrors (both dynamic) which have operating system and other files on two partitions; no other internal hard disks. I am not sure whether it has been configured like that on Windows 7 or Windows 10 as somebody did it before me and that person is no longer with the company.
The problem started on Friday after the restart on Thursday. On Thursday I noticed that there are some errors regarding file structure and MFT. As usual in such situations, I scheduled full check disk and restart for after business hours to occur. On Friday morning users called that they cannot access their dental software database which resides on the server. Upon logging in, I noticed that the dental software services are not running - and these services would not start at all, either giving dependencies error or that these did not start in timely fashion. We re-installed dental software on the server but no luck.
Then I ran (remotely) full check disk during the restart and although it states that the file structure has been repaired it seems like it does not do that because "chkdsk /r" should take at least more than 10 mins and the server restarts in 3 mins (I tried it with different switches and from safe mode probably about 20 times) - no luck. …
The Dell PowerVault MD3200 disk array accepts hard drives in the 3.5" LFF trays but can support 2.5" SFF hard drives fitted in the LFF tray through the use of an adapter.  If the array drives are of one type or another can the sizes be mixed in the enclosure without issue?
I removed a 1 TB SATA bare drive from a Seagate Go Flex external drive to recover important files but I can't detect it with my Anker dock.

Normally, I can put 2.5"/3.5" drives in my dock & detect them no problem. Still works properly with my drives.

The dock is capable of mounting 4 TB SATA drives.

The drive is warm to the touch & seems to be spinning.

Do I need a GoFlex disk adapter to read this drive or is it irrecoverable?

I also tried booting into Ubuntu to see if I could see the drive there but it wasn't detected
We are getting ready to purchase replacement laptops within the next few months. Currently our hard drives are Smart Harddrives and the systems came with 16 GB memory. We recently requested our memory to be upgraded from 16 gb to 32 gb due to applications timing out and having page faults.

Our IT staff is telling us that the new pc's will only come with 8 gb because they come with SATA drives that increase the performance of the computer.

In your opinion, should we stick with the 8 GB Memory and Sata drives, or should we push to get 32 GB with the Sata Drives.

We have some really heavy application resource users that I'm afraid the 8 gb ram will not be enough and that the sata drives won't make that much of a difference.

I'd like to know what others think.

Thank you
hello experts
I have a Dell R610 and PERC H700 as the disk controller, I did build up a RAID 6 with about 7TB storage space, ESXi 6.0 installed on it but the storage limitation still 2TB, as i know ESXi 6.0 already extend the limitation to 64TB, so whats wrong in my case and how to fix it?

thank you

I had 2 Seagate STDR5000200 external hard drives.

The first Seagate drive worked fine.

It was encrypted and has all our files from all PCs backed up since two months ago.

The second drive was not encrypted but was to be encrypted after all files from all PCs were backed up onto the second Seagate drive.

We backed up files from every PC to the second drive but one which was the Windows 2003 server was not backed up.

We left the second drive to backup files on our Windows 2003 server and we later found that the drive crashed and was corrupt.

We ordered in a new replacement for the second drive and had received a third Seagate STDR5000200 external hard drive.

I unpacked the drive and then plugged it into a Windows 10 PC we have.

A message came up on the PC asking if I would like to scan and fix this external hard drive.

This occured with other PCs I plugged the third drive into as well.

We finally got this drive to stop displaying this message but two out of three of these drives caused problems for us.

How reliable are the Seagate STDR5000200 external hard drives?

Howdy, did  a search to find  this, but nothing solid:
I know when it comes to adding  a new disk drive to a Dell compellent, it needs to be a certain firmware or else the SAN won;t recognize it.

Is it possible to find disks out on the googles, as opposed to going through vendor channels & paying 3-4x the cost of other similar disks? e.g. 2TB disk @ $600.xx vs $200 for a non-Compellent application..

I tried a disk that matched part #'s etc, but quickly found out , the disk needs to be...special..

We have a dell optiplex 390, shipped in June 2012. So 5 1/2 years old.

In June 2017 the OEM hard drive failed - not spinning at all.
Put in a couple / few year old hard drive that we had lying around.  Restored from backup.
Blew out accumulated dust (which wasn't much)

October 2017 - that hard drive failed. Not spinning at all.
Put in another couple year old hard drive

Used a couple year old digital power tester like this:
and power tested good per this:


Within a couple weeks - that 3rd hard drive failed -  put your ear to the drive, you hear it spin up for a couple seconds then silent whenever power is supplied.

Change out the original oem power supply? walk away from this?  thoughts?

the 3 drives were seagate and western digital (not fly by night brand).

yeah all 3 were not new when they died but I checked smart settings with crysttal disk info on the 2 replacement drives before putting them in. I forget the number of hours the app said they had been running.

I;ve taken the failed drives and connected to other power supplies - same thing - no sound or on the 3rd, it spins for a second then shuts down.

hi experts,

 I have 5 new dell workstations I'm setting up to be exactly the same in configuration. My questions is if I setup one workstation and then clone the hard drives on the other ones, will their be a license issue? they have windows 10 pro , office 2016, quickbooks and some other third party software. thanks.
I have a Dell Precision T7600 with a H310 RAID Adapter. there are two Virtual Disks. One for the OS (Ubuntu) and another for data. Two months ago I replaced the data volume with four new Western Digital 5TB drives in a RAID 10. Suddenly, this volume is unavailable. When I go into the RAID Controller and look at Physical Disks all disks are present but all four WD disk show as Foreign. Under Virtual Disks, the data volume shows only two of the four disks. One says Ready, the second says Rebuild and the other are Missing.

It seems highly unlikely that two disks failed simultaneously. There haven't been any electrical anomalies and all the fans and temp sensors in diagnostics are normal. I re-seated all of the drives and RAID Controller connections and no change. I tried Importing, which fails.

The data on this volume is really important. What would be the best way to recover this RAID?

Thanks in advance

I bought an Acer 8th Gen core i5 8250u based laptop model A515-51G.

Does the laptop support M.2 SSD in the second SATA slot.

Can I have a configuration where I can install the OS from the SSD SATA slot and also have the 1 TB hard disk that comes with the laptop for storing data.

Does this model support dual SATA configuration?

Does this laptop support booting from the M.2 SSD SATA slot with the default hard disk as the data disk?

What is the size and specs. of the SSD that I can install in the second SATA slot and whether I can make it bootable?

Please reply asap for this question.

Thanks for your support.

Warm Regards,

We have a Dell PowerEdge T710 and there are a total of 8 x 450 GB (15k) SAS.  There are 2 Raid partitions:

- 2 hard Drives = Raid-1
- 6 hard drives = Raid-10

Someone else setup this server and I am not sure which hard drives are set for which raid partition.  I do not want to assume that hard Drive Slots '0' - '1' are set for Raid-1.  How can I verify?  Please see the attached picture.

Replace - 1
I know how big each partition is and I can see what is installed on each partition so I want to know which partition is in jeopardy.  My questions are:

1.  How can I find out which partition the bad hard drive is assigned to, the Raid-1 or the Raid-10?

2.  How can I replace the bad hard drive with a replacement hard drive without loosing the data?
My process when a user leaves this company is to pull the original drive off their computer and store in a safe. Well that was the good old days. Now our computers come with M.2 SSD drives. If I pull this drive odd and replace what can I use if I need to read the data on it later besides plugging it back into it's motherboard? any recommendations are appreciated
hello! Thanks in advance for anyone out there able to help.

I have several hard drives, and would like to segregate folders AND files alphabetically based on the folder name. the way I've set up the disks as follows:

disk0 - A-R = files need to be located in d:\files\folder-A-R
disk1 - S-Z = files need to be locate in z:\folderS-Z

I would like the batch file to determine based on the folder name which drive to move to, and move to the appropriate path.
