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.

Hello we operate in a closed loop network, the only way to transfer files\data is to use a USB device or a CD\DVD.  With this being said we must scan any USB device that connects to external device\network before re introducing it back onto our closed loop network.  I've got to download several items a day, updates and such, place them on USB device scan then copy to our closed loop network this has gotten to take up a lot of time.  My question is are there any other alternative methods that wouldn't require a scan each time?

Hi, I have a SAN HP P2000 G3 SAS, where I had 2 failed disks. I replaced the disks but for some reason vdisk01 is offline and I cannot bring it back online. How do you bring a vdisk online without losing data? I do not know much about this so help me with details please
I have a unique issue here and I am no understanding autodiscover and outlookanywhere config enough to get around it.

I have 2 sites with 1 Exchange 2013 box with all roles in each as my production environment. It is fully configured and functioning externally and internally.

My box at the primary site(second site is not internet facing) is sitting on a clustered storage space which is degraded and will not rebuild on the replacement disk, backup attempts crash the cluster disk so day by day data is further compromised by the minute.

My only choice was to attempt to install another box in the primary site and move the mailboxes.

I have deployed a new bow (Exchange 2013 CU21 all roles) and moved my mailbox for testing successfully. Internally everything functions fine for my account, externally autodiscover, owa, outlookanywher do not work.

I dont' seem to be visualizing the proxy functionality correctly or have made changes on the new CAS which is breaking the functionality.

Current config is as such:

= Have changed nothing on the degraded primary site server or the remote sites CAS/Mailbox server
- This may be where I screwed up, but it tested fine internally so I thought the changes had no affect due to the proxying
          - Changed all web services URL's on the new primary site machine to match the degraded machine in preparation for the cutover after the mail box moves were completed.
                    - eg. degraded server autodiscover is …
Have a failing cluster disk with an Exchange 2013 CU16 Std VM on it. Pool will not rebuild on new disk and will only attach if the failing disk is in the array.

Storage was reporting no errors and only found due to failing backups, so backups are not current.

I have decided to install a new Exchange box and attempt to move the mailboxes. Issue is I onlu had access to Exchange 2013 SP1 and CU21 and the failing server is CU16 which is not available.

I do not want to even think about attempt installing CU21 on the failing space. My question is whether it is advisable or is a problem to install CU21 on the new machine and migrate the mailboxes with the version mismatch.

I am stuck, storage will not stay stable for backups, VM moves, or even attempting to copy the vhdx. I know the mailbox moves are high I/O but I don't seem to have a choice to to attempt it.

Will the 16 - 21mismatch be a problem?

If I have a 1TB drive, and 200GB is configure and allocated to VSS.  

Will there be enough storage for shadow copies be created for the remaining 800GB?   If so, is this because the shadow copies are compressed?  Just trying to get a better grasp of the service.
I am looking for a way to generate a barcode on a PWA (progressive web application) from a text string, display the barcode on the screen and also store it to a local storage via a service worker.

I can create the barcode using this excellent barcode script


However, when I try to save it as an image to store locally, I cannot seem to be able to do it. Possibly because I cannot give the generated barcode image a "name".

My code is...

echo "<h3 style='text-align:center'>Your Card Number is ".$cardno."</h3>";
echo "<div style='margin-top:30px; margin-right:auto; margin-left:auto; width:280px; margin-bottom:20px'>";
echo "<img alt='".$cardno."' src='barcode.php?filepath=images&text=".$cardno."&size=25' style='width:280px'/></div>";

Open in new window

Any advice would be appreciated
Hello Everyone,

          I am wondering how I can copy or transfer the entire contents of a 1TB external WD USB drive to a 2TB external WD USB drive.  

          Any suggestions regarding any special hardware or software needed to accomplish this task will be greatly appreciated.

          Thank you very much :-)


I am not an expert and I need help. I have two cluster SQL server each server has 4 Fiber Connection (FC) and I have two HP P2000 storage as shared device with two controllers each controller has  two FC. The design now is from each server there is 4 FC. Two of them connected to the first storage (one for each controller) and another 2 for second storage.

The storage has RAID1. However, if the storage goes down then the SQL will stop working. My question is there anyway that I can make the two storage to work as backup for each other (Redundancy). So, if storage one goes down then the second storage will be available and there will be no interrupted for SQL

Thank you in advance

Need to rescue 3 VM's running on a Problematic ESXi 5.1 host!

Here are the details of The Problematic Host:

Host = Cisco UCSC-C220-M3SBE Running ESXi 5.1, 1065491

Vcenter = NONE, This is a Standalone Host.  

Storage = Local Host Storage, File System=VMFS 5.58, Size=924.50 GB

VM's = 3 VM's Highly critical production VM's that cannot be shut down at all, Total size of used Space on the local storage is 548.29GB

ISSUE = Long story short, there is no way to fully diagnose the problematic host, and so the objective here is to either, move the VM's off the problematic Host and storage onto another host and storage, or just move the VM's to another Storage Device as quickly and non-disruptively as possible.

Here are my thoughts on this:  

Idea #1 I was thinking I could deploy a Vcenter 5.1 server either appliance or windows.   Then add the problematic host to vcenter.  And then add an NFS datastore and then storage vmotion the VM's across to the NFS Datastore.  

Idea # 2(Possibly Not as time consuming as Idea  #1), some how use something like Veeam or some other 3rd party solution.

Need your thoughts!!

Thanks for the HELP!

New Dell Precision 7820 Tower.  It came with the LSI 9440-8i Raid Controller.  I need to downgrade the operating system on this computer to Windows 8.1 Pro to accommodate a software package.  Since Windows does not recognize the controller card, I am struggling to find the driver in the format which the Window 8.1 will install.  Dell has the appropriate driver, but even "unpacked" it consists of .exe files.  

Does anyone have a way around this issue.

Thanks for your help in advance.

I'm looking to fix a server issue at a client site where the backup server has died and thus is in dire need to be replaced.
The current used configuration is VMWare 5.5 but an upgrade to VMware 6.5 will take place very soon.
The backup server VMWare host had usually the DRP storage attached and the replicas of the servers are stored in it.
The backup server was connected at the Storage with a 1GB link passing through  a Cisco SG500 switch.
There are about 10 Virtual Machines, including highly consuming ones like a SMB server and a SQL server

With the replacement server, I have two issues / Questions :
-  the replacement server has no storage  available locally and I don't see the point in adding it because the Thecus storage has already enough disk space with fast drives. Is it possible to use this disk space to run the servers ? I'm 98% sure but I like the 100% :-)
- The connection between the Thecus storage and the Fujitsu storage would need to be upgraded to 10GB to make sure the response time between the storage and the server is kept  at a correct level. Is it possible to connect the 10GB RJ45 port of the Thecus storage directly to the 10GB RJ45 port of the server to establish a fast connection between both of them ?
- If it's possible, I'd have in mind to put two IP manually on each network cards like on the server and on the Storage to configure the ISCSI adaptor on the VMWare Host.
- I'm also wondering about the DRP …
Lenovo TS440 Sever with what appears to be failed drive!

Okay, got a call and was asked to troubleshoot a server, lenovo ts440 4 drive bay server. It has 3 drives, the data resides in a raid one array with 2 4tb drives and I am assuming is okay. The other drive is a 500gb Seagate that held the OS Server 2016. I can get to boot screen and after that nothing, just hangs, disk repair yielded no help with same result. So question is, if I replace this drive and reinstall the OS will I lose the data on the raid one array or will windows see it already formatted with data intact and again I am assuming that array is okay, the raid controller shows it to be functioning correctly.

Thanks in advance and before you lecture me on setting an OS on a single drive with raid available, I didn't do it, I've just been asked to help.. Cheers.

Another thing, They have a clean backup that is a day old, backup is only system data files, not a system backup
How to add disk space to Thick provision eager zeroed in VMware? Right now it is greyed out, I tired to see if I shut down the server if I would be able to do it then and that is also not working.

I have HP DL380 G7 server that has 6 drives. Each two drives working under RAID1 configuration. One of hard drive failed (start to blink yellow color).  I want to replace it with a new one. I have same size hard drive but I do not know how to build RAID 1 configuration again for the failed drive.

All drives are SAS and hot swap. Are there any documents or video that can help me to do that?

Thank you in advance.

Create a reliable backup. Make sure you always have dependable copies of your data so you can restore your entire system or individual files.

We are contemplating purchasing some used SAS SSDs and would like to be able to verify the health of the drives before deploying them.  We use Crystal Diskinfo for SATA drives, connected via the motherboard controller, and it works great, but SAS SSDs are connected to RAID controllers (PERC 6i, H700, or H710) and CDI isn't able to display any information.  We've even tried configuring the SAS drives as JBOD or leaving them unconfigured, figuring that might do the trick, but it doesn't.  

As far as I know, none of our spare servers have onboard SAS.  Are there passthrough SAS cards that will allow CDI to read from attached SSDs?  

What's the best / easiest / most efficient way to check TBW (terabytes written) or health remaining on SAS SSDs?
Hello EE,

Wanted to run this past you all to see what route would be best to take. Newer VMs being brought online in our vSphere (6.5 Update 1) are reporting:

This virtual machine failed to become vSphere HA Protected and HA may not attempt to restart it after a failure.

From what I can gather my impression here is that maybe this could be;

1. A cosmetic in vSphere where  it is reported wrong, where disable and re-enable HA could resolve.
2. Not enough resources on other hosts for these new VMs to stay online in the event of a host down issue.

I am leaning towards #2 for our environment and just wanted to check with EE and see how you would best approach resolve for this?

Thank you for any feedback.
My Problem is RAID50 slow speed.

  • RAID Controller: SuperMicro SMC2108
  • Virtual Group: RAID50
  • Polices:

    3. Disk Cache: Enable
    4. I/O: Cached
    5. Disable BGI: NO
    6. Default Write: Write Through
    7. Used Operation System: Windows Server 2016


CrystalDiskMark Metrics:

What can I attempt to increase Write Speed?
Should I reconfigure RAID50 settings, or configure different type of RAID?

Had a Lenovo windows 10 laptop crash and it came up with Boot manager boot failed. It then progressed to the OneKey recovery screen with an option to recover. I presumed this would overwrite all data so I wanted to get some data off the disc first (I know it should have been backed up but it wasn't).

I removed the disc and put in an enclosure to attach it to another laptop.

When I had done this I tried to get to the folder where the files I wanted were but I could not access it. There were messages from windows that the disc had errors.

Chkdsk was run, although I think this may have been a mistake, and now I cannot even see the directory under which the files I want should be found.

I have downloaded a couple of 'data retrieval' apps but neither has been able to find the files I want to recover.

I am now at a loss what to do next.

I have considered going to professional data recovery experts but my wife won't sanction the expected expense.

What do they do ? Can I learn and do the same myself?

Is there anything further I can do to retrieve these files?

Any help would be gratefully received.
