Computer data storage, often called storage or memory, is a technology consisting of computer components and recording media used to retain digital data. In addition to local storage devices like CD and DVD readers, hard drives and flash drives, solid state drives can hold enormous amounts of data in a very small device. Cloud services and other new forms of remote storage also add to the capacity of devices and their ability to access more data without building additional data storage into a device.

I am going to back up two servers and maybe 3 workstations to it nightly. Don't need a lot of bells and whistles. Maybe 5-bays with RAID 5 or 6. Want something rock solid reliable and easy to maintain. I look at QNAP and there are just too many bells and whistles. Too many different models. Any suggestions?
I have a PNY 256GB USB thumb drive.  All of a sudden when inserting the thumb drive into my machine it is only showing the size to be 31.9 gig.   I have quick formatted the disk in hopes to wipe out the partition it is unable to read with no luck.   Has anyone had this happen to them in the past and know how to restore a missing partition?

Originally when I got the thumb drive it showed as 256gb I do not know what changed.
 I am trying to build a new server with three Micron 960GB SSD drives doing Raid 1 + hot spare. The motherboard is Supermicro SM X11SCH-F on Supermicro SM 733 TOWER CHASSIS.
 The question is whether to utilize built-in RAID controller to do what I want to do or buy more expensive controller like "LSI Logic LSI00344 9300-8i SGL SAS 8Port 12Gb/s".
 In the past, I always purchased  "LSI Logic LSI00344 9300-8i SGL SAS 8Port 12Gb/s".
 However, I am getting SSD drives which are so much faster than SATA or 12Gbps SAS, so I am wondering if there arereal benefits of spending $700 for  "LSI Logic LSI00344 9300-8i SGL SAS 8Port 12Gb/s".

 I would appreciate your insight.

I have  Dell MD3420-21.6T-SAS-OEM lying there with no use... :) So I want to use it ...
Few questions...because I never touched one of those ... I downloaded few guides but not sure how to configure....

How do I Start using it ? Do I must use ESXI and WMWARE and to add the server as a storage?
Can I use this storage as regular data storage? just to configure storage for files and give it IP address ?

Any reference will be great...
My small business is getting a Dell Poweredge T440 and we were advised to use Raid 1 for the OS and Raid 5 for the other drives.

We are going to get 8, 3.5 inch slots for HDs. OS will use 2 drives and Raid 1. Then we want 4 drives to be set up with Raid 5.

Does this give us 4 drives and 2 "hot spares"?

I'n not familiar with Proliant servers. I seem to be getting mixed info on drive array on HP Proliant DL380 Gen 5 server. The front panel drives are listing these as 60 GB drives. There are 5 of them. If I go into the system management home page, on the array controller, it lists the physical drives as 466 gb (I assume 500 gb) drives and there are 5 listed in the physical drive listing. I will attach a screen shot of the management console. I'm also attaching a shot from the front of the server and the E200 array that shows no physical drives. Not sure why there are 2 array's in the computer. The first was an P400 array.

One of the drives in the front panel is showing a solid green LED light on. From what I've been able to locate, that indicates the drive has failed and has been taken offline by the controller. Is that right?

If I go to replace the drive, what do I actually use? I see that there are 60 GB hot swap drives that were made for that unit but the management console is giving me a different picture so I'm not sure what to try.

Any advice would be greatly appreciated.


I noticed a couple reviews with Highpoint's new M.2 NVMe RAID controller . What I noticed  was that there were testing with consumer NVMes which begs the question about what is going on with TRIM/Garbage Collection.

   Everyone was staying away from consumer SSDs in servers primarily because RAID controllers didn't support TRIM. Have they made any major improvements to TRIM or Garbage Collection?  Do any RAID controllers at this point support TRIM? or are you still limited to Enterprise SSDs/NVMes in servers for power protection and garbage collection?
I am running Exchange 2016 on Server 2012 R2 Std.

My server has 3 RAID Volumes.

relative to "diskpart detail disk":

Disk 0 (2 partitions, Volume 0, Volume 1)
Disk 1 (1 partition. Volume 2)
Disk 2 (1 partition, Volume 3)

My event viewer (log = SYSTEM) has the following warning that comes approximately in a cluster of 4 about once per day:

What does "\Harddisk3\DR5" refer too?  How can I find out?

Is it Volume 3, physical disk 5?

People today are virtualizing servers just for the sake of virtualizing. I started playing. I have an old Server laying around. E3-1230, 16GB memory, Adaptec 6405 controller with three new Seagate 7200rpm SAS drives in a RAID 5 configuration. It is dated but not a real slouch. So I installed Server 2019 Standard the installed it again as a VM and migrated my Server 2012 to it. First thing I noticed on my workstation was that things were running slower. Not to a dead stop but noticeably slower.

   So what the heck. I virtualized a Windows 10 Professional workstation. It doesn't do much but it is so slow doing everything it is painful. I would kill myself if I had to user it every day. Between the virtualized server and workstation I have to be doing something wrong. They just shouldn't be that slow what what I have heard. Both are Hyper-V. I have to be missing a basic setting. Any general help or guidelines on what I could be missing?
We have a VNX 5300 which had an issue with one of the SPS. Now that the SPS for SPA has been replaced, we are showing all of the initiators to be yellow and are stating that they are not logged in.
Do we need to do a reboot of SPA to get these to login or is there something that has to be done now to get these to login again so that we have redundancy with both SPA and SPB initiators be logged in?
Issues with Outlook 2016…about 4Gb in PST…
Will recieve but not send..

Bottom right corner says sending 1 of 32...and the "offline' is showing...
But the Outbox is empty...I do not know where those 32 emails are that Outlook is trying to send...

What I did...
1.  Moved last 2 years of emails to a storage pst file...
2.  Moved everything else that was older than 2 years to the storage pst file...Got pst file down to about 1 gb...
3.  Closed pst and when opening I got an error 0xc0000142 which pertains to some DLL file cannot access the application....or words to that effect...
4.  Rebooted PC and then I can open Outlook...
5.  Ran SCANPST...found some errors and repaired...
6.  Ran sfc /scannow...
7.  Ran a full repair of Office 2016 from Microsoft...downloaded new files etc...Reported no issues...
8.  still have to reboot pc before Outlook will open…but it is opening…
9.  Under Send Receive ribbon the Work Offline button seems unresponsive…
10.  Did notice this time that while it does not send…it will after about 10 minutes…or if I shutdown Outlook…when I reboot and open Outlook…the email will have been sent and will be sitting in the reciepients  inbox…

So...Unless you experts have different plan is to Uninstal Office 2016...will probably use Revo in an attempt to get "everything"...
Then set up Outlook with a new pst file...then open the old PST file and move whatever emails and contacts the client needs...

Thoughts and ideas …
 I am going to buy HPE PROLIANT ML110 GEN10 SOLUTION - TOWER - XEON SILVER 4110 2.1 GHZ - 16 GB server (Part# P03687-S01) without a separate RAID controller (likeHP 830824-B21 Smart Array P408I-P S) to cut down on cost.

 Last time, I purchased HPE MIDLINE - HARD DRIVE - 1 TB - SATA 6GB/S (Part#: 655710-B21) for this server.
 However, this time I wanted to get 2TB HD of the same kind, but ran into  "HP 2TB 7200 rpm SAS-3 3.5" Internal SC Midline Hard Drive (MFR # 818365-B21). It is SAS even though it is only 7200 RPM.

Is there an expert out there who have used this hard drive? If yes, is it:
(1) Compatible with HPE PROLIANT ML110 GEN10 - TOWER - XEON SILVER 4110 2.1 GHZ - 16 GB?
(2) From performance standpoint, is it worth paying more to get this HD over a typical HPE 2TB SATA like "HPE Midline - Hard drive - 2 TB - hot-swap - 2.5" SFF - SATA 6Gb/s - 7200 rpm (Part# 765455-B21)"

 I am going to get three of these and set up RAID 1 with one hot spare and will run Windows Server 2016 with two virtual servers (first VM - W2016 Domain Controller, second VM - W2016 Terminal Server running Quickbooks and other Tax software for two concurrent users).

One of my co-workers brought in a shoe box full of old 1.44 floppy disks.  Every disk that I put in to the drive says "You need to format the disk in Drive A: before you can use it". Is there a dynamic fix on this or do I need to do something to every disk to get it to work?
Best solution to sync HUGE QTY of files across slow WAN?

Hello creative experts!

I have 1.7 million files (4 TB) in one of our remote offices.  

We presently use Vice-Versa to replicate the remote office data to headquarters.

Vice-versa is installed on a server here in HQ.

The initial "comparing source vs. destination" part of the run takes 21 hours over our 50 mbps wan connection.  

The actual file copy of changed files typically takes about 3 hours.

I'm guessing it's soooo slow because it's having a chatty conversation across a slow WAN connection to determine which files got added and deleted.  [This is a total guess as I don't know how the software is written]

What's the best solution?

Is there a solution that perhaps has agent software running on the other side such that each side determines local changes and THEN compares notes?

Is there a solution that works something like OneDrive?  (For example: there's no day long process evaluating local vs cloud before figuring out what to sync.  I presume if you delete a local folder, the agent gives the path of what to delete to the cloud and it's deleted.  Likewise, if a file gets added locally, just that file gets uploaded).

As I type this: I wonder if there's a microsoft solution which could leverage our E3 Office 365 subscription for our 400 users?

We started getting quotes for cloud backup and it was surprisingly expensive: maybe $90,000 per year for 8TB  - that's super approximate but …
Hi Experts,

I'm trying to build a raid 5 array for our file server using the following:
1.  Dell Poweredege R530 - server
2.  Windows Server 2016 - OS
3.  3x 4TB SAS - Hard Drives
4.  PERC H330 mini - embedded raid controller of dell server

But in my inquiries from diff. forums, I get these ideas:
1.  There's a risk in Raid 5 using large disk, like rebuilding array takes times and probability of failing another disk during the rebuild is more likely to happen.
2.  And raid controller without cache is not wise to use in a parity raid.

Since the PERC H330 is an entry-level raid card which does not have the cache. Is it more wise to use software raid in this situation or stick to using the built in raid controller?
Should I go building the Raid 5 array with 4TB disk?
What's should be the best option for this?


Diagram of the Setup

We're starting a datacentre migration (and also domain) and are looking to migrate from DFS (2008 R2) to NetApp Filer (don't have the specifics yet but it will be a very recent, if not latest version of OnTap etc) via the usage of a tool called Peer Sync - I have read in various places, including here, about adding the NetApp as a leaf to the DFS - what does this actually mean and provide - is it the ability to be able to migrate the data from one to the other? Is it just an option you choose in DFS or from the NetApp side?

Not only are we migrating datacentres but we are also wanting to move to a different domain - I have 2 options available to me: one is to move to a NetApp device on the same legacy domain, thus achieving datacentre migration and then at a later date to move to a different domain OR move to a NetApp in the different datacentre and on the new domain straight away - what are the pros and cons of each option and which is best advised with time being a mitigating factor?

I'm currently running a Treesizes report against the namespaces to id share sizes and to see if there are shares with minimal new created files, in order to id candidates for the first migration\quick wins - at the same time I have another team providing a Varonis report on which shares are least accessed.

Appreciate any advice on the above and anything I may have missed.
Hi Experts;

I need a clear advice on the Ms Access tables storage size:
Our client with a supermarket has many products on the shelves, now our current Point of sales works as follows:
(1)      For every product line, five line entries are generated as follows (Revenue line, Vat Line, Cost of Sales Line, Stock line and the Cash/Receipt line)
(2)      All the five lines are stored in POS Table details
My question or worry is can this table manage to handle let say 850, 000 product sold per year which is equal (850000 X 5 lines = 4,250,000 lines) if an access table can handle that, then can we continue to use the same POS for the next 5 years? Will it not burst???????
The above line represent data that will be required for accounting purpose, example:
(1)      Revenue Account
(2)      Cost of sales Account
(3)      Vat output Account
(4)      Stock Account
(5)      Cash/Receipts Account
The performance as at now is very good no issues at all.

I'm using a SATA hard drive adapter cable to use a known good hard drive for external storage. My PCs (Windows 7 and 10) see the adapter as "USB Drive" but show the drive capacity as 0 bytes.

When I view my drives in Disk Management, it shows Disk 1 as Removable with "No Media."
"No Media" image from Disk Management
I've gotten the same results using another known good drive. I've also had similar problems with other SATA hard drive adapters - including ones whose IDE adapters worked flawlessly. So far I've always given up and gotten an external case to make it work. But I liked the convenience so much in the past that I'd really like to know why this isn't working for me now.

Any help you can offer would be greatly appreciated.
I'm currently attempting to resize an 3PAR iscsi virtual volume partition within RHEL 7. I think I'm most of the way there, but lsblk still shows my old partition size of 39TB instead of the new 64TB the volume has been extended to. I've never user iscsi or multipath before, so it's all new to me. I've cribbed by via the RHEL documentation, but can't get the actual partition to grow.
I've used the following:
but they don't go into the final step of resizing the actual partition, so I get this (I've unmounted the drive from the mount point for now):
sdc                          8:32   0    64T  0 disk
├─sdc1                       8:33   0    39T  0 part
└─mpathb                   253:4    0    64T  0 mpath
  └─mpathb1                253:5    0    39T  0 part
sdd                          8:48   0    64T  0 disk
├─sdd1                       8:49   0    39T  0 part
└─mpathb                   253:4    0    64T  0 mpath
  └─mpathb1                253:5    0    39T  0 part

Open in new window

The most obvious solution would be resize2fs, but that gives me device or resource busy.

I'm not great with Linux, so please excuse the newbie question.

So where do I go from here?
