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.

In those systems with 16GB of optane memory and a regular mechanical sata drive, would it be better to replace the optane memory  with a nvme drive?  I have a customer getting a system  to produce music. It  comes with 16 GB of optane memory and a regular hard drive. The optane only speeds up the operating system. I’m thinking it would be better to take out the optane memory and replace it with a nvme drive. They’re cheap these days.

When I save a new 2013 Excel file for the first time it always tries to save to some cloud location. My "Save" settings in options are set properly with my hard drive location. How can I change this? Thank you.
Hi there.

My brother got an issue with a Seagate Central network disk. The network part doesn't work anymore, and he wants to rescue the data and copy to a usb-disk/computer drive etc...
The challenge is that Seagate utilizes a file format related to Ubuntu/Linux. He tried to pull out the hard disk from the storage unit and hook up to a Windows computer via USB. That didn't work that well, because the 3TB drive apparently is formatted in like 500GB partitions with a Ubuntu/Linux format. That is not recognized by Windows.
So the task is how to move/copy data to a "normal" disk that will work with Windows.
I found a Gparted software that is supposed to do the trick, but we're a bit insecure about what to do and if this is the right procedure.
Did any of you out there try a similar task? We would prefer if it's possible to do the whole thing with a Windows based software.
Looking forward to your suggestions.  :-)

Best regards

I have a PERC H330 card and would like to build an 18TB raid 5 array out of four HGST 6TB SAS disks. Two disks are 512b, 6Gb/s and the other two 4KB, 12Gb/s.

For some reason though I cannot add them into the same array. They work in separate raid 1 arrays but that isn't what I want.

Is it perhaps the case of an old firmware version on the PERC card (4.290.01-8335) or I simply cannot combine the two types of disks together?

I need to know the difference between
-  HPE 128GB (1x128GB) Octal Rank x4 DDR4-2933 CAS-24-21-21 Load Reduced 3DS Smart Memory Kit
- HPE 128GB (1x128GB) Octal Rank x4 DDR4-2666 CAS-22-19-19 3DS Load Reduced Memory Kit

I mean which one has better performance

In the old days adding a fast hard disk to a computer with a slow hard disk ended up with both hard disks running at the speed of the slowest,  Does this also apply to a primary SSD with a secondary normal hard disk?

I need your help to put together Powershell script to

Script 1 - BAK extension file Audit

1. Script needs to be able to use input server file (server bulk)
2. Scan servers drives (E:\, F:\, G:\ or I:\) or be able to select drives
3. Look for  “*.bak” extension files.
4. Generate CSV output files with
       a. server name
       b. Bak file name and path
       c. File Size
       d. Dates temp of the file.
       3. hash
5. Email report to specific email address

I have a Audit script but it doesn't work correctly. It scans all drives, doesn't provide date of BAK file creation. It doesn't sent email with report

$ExtensionList = @('.bak')
Get-PSDrive -PSProvider FileSystem |
    ForEach-Object  {
        Get-ChildItem -Path $_.Root -Recurse -ErrorAction SilentlyContinue |
            Where-Object { $ExtensionList -eq $_.Extension } |
            ## ForEach-Object { $_.Name, $_.FullName, $_.GetHashCode() }
            Select-Object @{Name="Name";Expression={$_.Name}}, @{Name="Hash";Expression={$_.GetHashCode()}}, @{Name="FullName";Expression={$_.FullName}} |
            Export-Csv -Path C:\Temp\BAKAudit\BAKAuditReport.csv -NoTypeInformation -Append

I don't have BAK deletion script, which should do as follows

Script 2 - BAK Deletion
1. Use generated output file (from script 1) and remove"Bak" file older then 3 days.
2. Once the deletion is completed another report should be created showing what bak files from which server and from …

Computer will boot to initial screen showing background and "Time" in bottom left corner.  This prompts the user to press "Enter" - which usually provides the screen to enter login credentials.  The only thing that appears is a black window and NOTHING happens.  Eventually, the screen returns to the initial screen showing background and time.
I can get the computer to boot into Safe Mode.
I've run sfc /scannow.  This returns a prompt stating it has found corrupted files but cannot repair them.
If I attempt to run DISM commands, the commands run for several minutes.  However, I'm then prompted that these commands cannot be run in Safe Mode.
I've removed the hard drive from the computer and have attached it to another pc running Windows 7 professional.  This PC has assigned the external drive with the drive letter M:.
1) Can DISM commands be run on this external drive?
2) If there has to be a "source" from which corrupted files can be obtained and copied to drive M:, how do I provide that source.
MD3200 with most recent firmware being used in a two node Hyper-V cluster.  The cluster is Windows Server 2019 Datacenter.

Here are my host mappings:

I need host HYPERV01 in the Default Group since, as you can see from the picture, all the virtual disks and so forth are mapped to the default group.  I cannot at this time move storage from one hyper v node to the other.  When right-clicking on Host HYPERV01 the move option is greyed out.  Host HYPERV01 has only Virtual Disk Access mapped to it.  I believe Access gets mapped to everything.

Question:  How can I move Host HYPERV01 back into the Default Group?  
End Goal:  I need both hosts HYPERV01 and HYPERV02 able to access all storage.

Hello. I have a brand new Windows 10 laptop and I want to run virtual machines using VMWare. I am thinking about partitioning my SSD and allocate a partition to store my virtual machines. What format should I select for this new partition? NTFS? Fat32?

PS: I read on internet that the best would be to store the VMs on a separate hard drive but
1- My laptop does not allow me to add a second hard drive
2- It adds cost...
3- I could buy an external HDD but I would loose on speed

We use HDD duplicators here at our school. Over the years, we've duped both standard HDD and SSD drives.

This year, our laptops came with 256ssd drives from SUNEAST

These drives take 4-5 TIMES as long to duplicate....even using the setting that only copies the content, not a full sector by sector copy

Yesterday, it took 3.5 hours to duplicate 98GB of data to one of these drives.

Any ideas about why this is happening?  I have 3 different duplicators and it's the same slow speed on each.

Within the laptop, windows 10 runs just fine...8GB RAM Dell Latitude E5440

But duplicating is like molasses.

I have a P5 IBM Server running AIX 5.3.  The machine crashed and the rootvg is no longer accessible.  There was a 2nd hard drive on the system with data that I would like to move to another P5 AIX 5.3 system but not sure how to do this.  I physically moved the drive to the other system and it shows up with lsdev -Cc disk but not with lspv command.  How can I make this disk accessible to this new system
so I can retrieve the data?
I use Acronis. The basic way it works is that it does a full then incrementals thereafter. It will only keep a certain number of incrementals at which point it merges the oldest incremental in to the full thus creating a new full. The sync program would have do to it by "block" or whatever you want to call it or it will continually be trying to sync the huge full backup every day.

   The perfect way to do it would be to back up nightly to a NAS or big External Hard Drive and then sync that hard drive or NAS to the cloud. Same issue with merging the oldest incremental in to the last full thus creating a new full. So does anyone know of a sync program that is "block" aware of wherever you want to call it?
We are considering hosting our own cloud backup location for a handful of servers that are hosted by commercial companies.

Looking at 150 GB of data backup per month and a monthly OS disk image of three or four servers approximately 200 GB total.  Most of it is archival and the image files would be rotated possibly maintaining 2 images per remote server at a time.  Currently using AWS with SyncBack.  Unfortunately started with Jungle Disk because at the time SyncBack did not interface directly with AWS.  This has led to enormous expense in retrieving things from Glacier and dealing with Jungle Disks changing file names/data to proprietary scheme so you can't see actual file names in Glacier.  And JD does not have Glacier retrieval function.  The server hosting companies charge almost as much for regular image backups as for the monthly server fee and I have heard that their backups are not totally reliable.

In spite of that very costly situation and the recent cost time and money required for us to retrieve a 5 TB archive, AWS charges too much and they have a ridiculous amount of tiers of charges and fees that it is nearly impossible to know what charges are coming on a monthly basis.

Looked at Azure and it looks slick but it isn't free or inexpensive even with our moderate amount of usage.  So we are considering hosting our own cloud backup.

We have extra servers so no hardware expense except a few large drives.  We would figure out some secure VPN / FTP into the…
Hi, i have a 3 server S2D setup that i want to add new SSDs to.

Currently i have a storage pool with 10 HDDs and 2 400GB SSDs on each server. I have 1 volume using 50% capacity of both.

I want to add 3 new SSDs into each server that are 1.6TB each and create a new volume that uses 33% of HDD and new SSD storage.   Once i have then migrated the data off the existing volume i will delete it and create 2 more using roughly 33% each.

Is it possible to do this? Any help is appreciated!
Can a Lenovo Centre M 5032 AF8 desktop PC support a nvme to pcie adapter card with an nvme m.2 ssd ?

I would like to install an nvme to pcie apdapter into this desktop, and then install nmve M.2 SSD in the adapter.
The nvme ssd would be used only for database storage.
I am not interested in booting up from this device.
I have upgraded the bios in this desktop to the latest bios version.
Before I buy an nvme m.2 SSD, I would like to know if this desktop will be able to support an nvme m.2 ssd.
The desktop has a 64 bit version of Windows 7 installed on it at this time.
All thoughts appreciated.    Thanks, Jim
I have an HP Proliant ML110 Gen 10 Sever and he customer wants Windows 10 Pro on the server.   I know that this is not the best thing to do, but that is what they want.   I cannot locate the driver for the "HP Smart Array S100i sr Gen 10" for Windows 10 Pro.   I downloaded and extracted the driver for Server 2012, 2016 and 2019, but the driver doesn't seem to be in those.   Any idea where I can locate it?
I can't get one of my servers to power up. I don't believe it's a hard drive issue, more importantly for the sake of this question, I don't believe it's a hard drive issue. How do I recover data from the RAID?
I was working on organising some 112 zip folders containing some training files that I purchased recently. These were located on an external 3 TB Seagate hard drive (separately powered).

When I was almost done, I suddenly noticed that all except one of the folders had simply disappeared.

I have been desperately trying to find those files, thinking that perhaps I may have accidentally moved them to another folder, but no, those files no longer exist on that drive.

Currently I am in the process of running chkdsk /h /f /r /x on that drive and hoping something would come up. Besides a friend suggested it could be that the allocation tables are corrupt so I might have to resort to expensive data recovery tools or services.

Any help would be welcome from this forum please. Those files together cost me about $800!!

Some time back I had experts help me with a bunch old DVD I wanted to put in the cloud.  Today I have a series of DVD that the computer just doesn't recognize as to "No DVD  in D: drive".  I have checked the DVD and seem somewhat dirty or grimy or scratch? (that is my appreciation) - when I place them in my hands they do seema bit scratched and some grime "maybe" in some places; I say grime because if I press it it smudges  somewhat (if u take a cloesup on certain areas u can see them).  So i would like to know if you guys can take a look at the image and recommend if there is a way to fix them or clean them or what can I do to be able to have my computer read them.

Will Centos 6.5 running the 2.6.32-431 64 bit Kernel support an m.2 nvme ssd plugged into an NVMe to PCIe adapter in an HP DL585 G7 server ?
We have a Datto Alto (Model Datto-1000) backup drive that was just replaced with a newer model because the hard drive was failing (SMART Errors).  I have searched online and can't find any information on replacing the hard drive with a new one.  

I would like to simply replace the internal hard drive and then use the system to perform local backups for other server's.  Has anyone seen this done or it my old Datto Alto basically a paperweight now?

Hi I have to replace some SAS drives in a Power Edge, they amy SAS hard drive all in hot swapable carages.  The SAS connection is like the crummy pix I took, it has a single cable connection.  When I go on Amazon to get a SAS drive, the pix all show they have the SATA connections.  I don't know if they are mis labeling their parts, or just use the same pix as the normal drive.

Also, I thought that SAS drives were either 10k or 15K RPM, these are showing up as 7200 RPM.  

Thanks all.
I recently upgraded my hard drive to an SSD.

Everything is working great, but SQL Server is running so slow.  I don't know if it's rebuilding indexes or exactly what.

For example, I can usually run an export task that I usually do in about 3 minutes.  It's taking over 3 hours right now.
Is there a limitation on the size of an external hard drive for an iMac.  I've read that there is a limitation of 2.2TB but cannot find out how old the article is.  I want to make sure before I rush out and buy a 6TB drive and then find out I can't use it
