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.

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.

I have over 60 stores that use cash registers for sales.  I have a method of collecting every transaction from a cash register by capturing the cash registers electronic journal through the serial port.  The data is all text based, but very unstructured.  (I am including a sample file of this data capture to this post.)

The question I have is this:  IF you were tasked with storing, then retrieving and analyzing these data; what type of database storage system would you use?  And why that one?  

I am waffling on whether to use a SQL or NoSQL solution.

Thank you,

Here is a sample of the raw data capture.  (Note: about half of the way down there is something called a "Z report"; which is run when a cash register is closed out.  That zero's out all of the balances and totals during that period of time it was operating.)

I currently have a site where we had originally purchased a 3-2-1 (3 servers – 2 ISCIS – 1 SAN) solution back in 2012. The SAN was upgraded about 4 years ago, but we are really at a point where we need to do a full refresh. Overall the setup has been good and haven’t had any major complaints from end users.

Due to the single point of failure and latency sometimes incurred during backups, large upgrades to our application server which uses SQL, and RDS use, I was hoping to move away from SAN and use local storage while keeping the HA / vMotion features.

Obviously, VMware’s vSAN came straight to mind even though I knew I’d basically have to purchase all new licensing (Currently Essentials Plus) and vSAN.

We will be replacing all our Windows 2008R2 VMs with Windows 2019 but here is a quick overview of performance:


After the upgrade it be similar to another site and VM count.
Overall we should not have over 12-15 VMs. There will be 1 RDS server which will probably have around 32-64GB of RAM but I usually dedicate a host for that VM.

I called my Dell rep and tell them about the refresh and budget I’m trying to stay in for hardware and any VMware licensing and of course they come back with the vxRail solution, Enterprise Plus Licensing, etc, with a price point 3x my budget. I feel like I’m talking to a car salesman looking to see how much they can get out of me and…
Currently in our environment we are using NetApp  for our VMware environment, but will most likely will be purchasing a new Pure Flash array shortly.  We do have FC connecting our hosts the the upstream switches, but do not use an MDS. If we want to use FC with Pure, how would we zone the storage. Would we need to do lun masking on the host side?

I have a stand alone Hyper-V server, VMs are located on a storage on a iSCSI shared disk.
Now I have another server to add as an Hyper-V new node, so the idea is to configure Hyper-V fail over cluster.

It's possible to "migrate/install" the actual stand alone Hyper-V production node to the new scenario using the same iSCSI shared disk ?

Can load the VMs load over the 2 nodes ?

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

Really I just want to check that what i am doing is a supported config.

I have 3 servers i use for HCI using S2D 2019.

I have 3 Virtual Disks all using 33% of the storage minus 1 spare HDD for failure(cache + ssd + hdd) seems to be working ok.

I want to add 8 1TB drives into each of the servers to create a new virtual disk that only uses cache + hdd.

The HDDs are a different model than the HDDs used in the other 3 virtual disks. I know that i should utilise only the one storage pool, but would i still be in a supported configuration, on top of that how would it know what disks to create the new virtual disk on? I dont want it to attempt to use the space capacity disks i currently have (they are 1.6tb disks) with the new ones i intend to use (1tb disks)

Thanks in advance for any feedback!
When I go into my Photos app, I'm seeing pictures that go back to 2017. When I look at my Storage, it says that I've got over 4 GB of photos sitting on my system. Yet when I go out to my Photo library, I'm seeing this:

Photos screenshot
Everything obvious says that the only pics I should be seeing are 2019 and that's it. I've saved everything else to another drive, but the fact that I'm still seeing pics from 2017 in the app and the fact that over 4 GB of photos are still on my system tells me that there are pics on my system that I'm not seeing.

Where else can I be looking?
Hi We are using Visual Studio and we want to start storage PDF or some other files in DB but we would like to know which is the best DB to do it?

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 have deleted all of the content in my "Documents" folder and yet this graphic tells me that I've still got 14 GB of content in "Documents."

Where would this content be?

I need to know the difference between

I mean which one has better performance

Dear Vmware Experts

We have VSAN Hybrid cluster 18 nodes  with around 370 VMs  

Every server has 2 ports every port 10 G

Our core switches has 40 G   speed

Right now we have some performance issues most of the performance issues related to the Storage and network performance

So we are going to buy a new 6 servers and we are going to build all Flash VSAN cluster

The new servers will have 2 ports  10 G each  and 2 ports 40 G each

Both cluster new one and the old one will be managed under the Vcenter  (( we are using VMware distributed switch ))

After we build the new cluster we will start to migrate the most critical VMs from the old cluster to the new cluster one

And here my questions

1-      Using V motion changing host and data store between two clusters it will work without issues?
2-      When I V motion a VM like file server 40 TB can our user still use this file server or this not possible due to performance issues

My main concern for such plan the effect for availability and performance for the VMs which I want to V motion between the two cluster

Do you have any recommendations to achieve such target with fewer end users interruptions

Kindly advice

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 …
Single Hyper-V 2012 host server, one Windows Server 2012 VM running SQL Server 2016.
iSCSI storage is connected to host via two 1G links (MPIO).

PerfMon traces on the host server show high latency (40ms+) on iSCSI NICs, but only 20-50% bandwidth usage.

Storage system stats show similar info to host.

We're considering upgrading the SAN to 10GbE, but not sure that would improve performance we're not maxing out the current bandwidth.  Same uncertainty for adding additional links from host to storage

What other information can we gather toward identifying bottlenecks?
How can we improve iSCSI latency?
Please please can I have a DEFINITIVE answer:

I(f I am running exchange 2010 and above, with the program files on c drive and database on d drive, using default exchange values, will the mail flow be disrupted when the disk (c or d) gets to 10% or below
If not, will the disruption just depend on how much physical disk space there is for log files, database data etc and not on a % cut off

Can someone please give me a precise answer on this

while I was working with my USB stick,something wierd is happened : it switched in read only mode. From a specific point an error message has been shown and I haven't been able to copy files to the usb stick anymore and also I can't delete files inside it and I can't format it. I google a little bit looking for some solution and I found two ways to fix the problem,but they didn't work. I have also plugged in the stick on another computer to check if the protection could depend on the OS,but not. It is write protected also when plugged in a different PC. So,at this point I don't know what to do.
Hello and Good Morning Everyone,

         I am wondering if it is possible for new and unused external USB flash drives to become defective or bad over time.  The reason I ask is because I am considering buying a pack of external USB flash drives for quick and convenient data backup and restore purposes.   Realizing there might be some new ones which might not get used for several months or even a year, I do not want to take a chance on them going bad simply because of non-use.

         Any thoughts shared to this question will be appreciated.

         Thank you

Experts - trying to get some ideas on how to manage email attachments that find their way onto an Exchange 2013/2016 mailbox database.

I have a customer who receives orders via email attachments - and they receive a high volume of these type emails which keeps the current 2016 mailbox database growing.

I'm trying to get an idea as to what type application solution would offer combing through the existing mailbox database and relocate/redirect defined email attachments (pdf in this example) - to an alternate storage location on the network - yet maintain the logical connection of the attachment to the original email message when the customer might go back to that 3 month old email to pull up the attachment for review.

Curious as to suggestions and whether you've had any hands-on experience with specific applications and how buggy and/or efficient the application performed...thanks much -

Unfortunately Dropbox quits syncing when you log off. Has anyone come up with a solution that keeps Dropbox running and syncing even when logged off the computer? I am trying to use it for server backup storage and not syncing when logged off will be a show stopper.
We have 2TB of archived files that we want to move to Cloud storage. The current 2 TB of files will increase as we archive more data, so for now we would need 2.5 to 3 TB of space.

We will need users to be able to access the files (read only) as needed and be able to download from the archive as needed.  

Azure file storage is to expensive at this time.  

Do not want to use AWS because we are using Azure for Cloud backup and will eventually use Azure for file storage.

Other than Dropbox, can anyone recommend another Cloud storage solution for storing these files.

Is there any documentation/tutorials/guidance regarding optimizing ZFS datastores for mostly-read, mostly-write, and heavily mixed read/write? For example, having a separate datastore that contains predominantly data that will be read, but never changed...and then optimizing the ZFS/disk parameters to maximize performance for mostly-read.

Is there any quantified benefit to this form of fine-tuning? Or is it fluff?
Hello all,
I'm configuring an HP Z420 workstation with a 1TB SSD system drive (Boot /OS Drive) and two Enterprise 4TB SATA HDD for storing all my data in RAID1 . I wanted to know what the best RAID1 configuration would have the best performance for how I will be using it.

I mostly will use the workstation for document editing (word, excel, PDF, PowerPoint, Visio, etc.), internet , watching videos.

I plan to store A LOT of personal photos (thousands) in RAW format (each can be 15MB to 40MB) on the 4 TB RAID1.  I do some minor photo editing on photos using Google photos and I also store personal video files as well. I rarely edit videos and they are usually no more than 15min long but I do have a few longer than 1hr.

The workstation has the following RAID CARD:
LSI Logic SAS9260-8I SGL -8PORT, Int 6GB SAS/sata,  Pcie 2.0, 512MB RAID Card WITH a battery backup on the card itself. I also have a UPS for the computer as well.

The RAID configuration page has the following options (Image attached):
- Raid Level (I chose RAID 1)
-Stripe Size ( the options here are- 8kb, 16kb, 32kb, 64kb, 128kb, 256kb, 512kb, 1MB)
-Access Policy (RW is the default)
-Read Policy (options here are- Normal or Ahead)
-Write Policy (I chose Write Back with BBU since I have the Battery backup unit but other options are Write through, Always write back, write back w/ BBU)
-IO Policy (Options here are- Direct or Cached)
-Drive Cache (Options here are- NoChange, Enable or Disable)
I'm struggling to connect a Macbook to a Microsoft Azure file share storage account. I have it working on 3 Windows machines. What's strange is an open port scan says that the port 445 is closed, and yet the Windows still work. Really need to connect the File Share to the Mac. Grateful if someone could help advise.
I have a desktop computer (Alienware) with four internal hard disks, with a RAID motherboard.  Two of the disks are striped (the c:\ drive) and the other two disks are mirrored (the d:\ drive) and contain all my data.  The c:\ drive contains my operating system (Windows 7) and all my programs.  I want to replace the c:\ drive disks with 2 SSDs.  I want to clone the c:\ drive and then transfer this clone to the 2 SSDs, which will constitute the new striped c:\ drive.  I have cloned and transferred an old hdd's content to a new SSD, but without RAID.  It was easy.  But how do I do the same with a RAID system?  I'm at a loss as to how to proceed.  

Thanks, WmABradnan
