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 have four actual hard disk drives and two optical drives - c thru h. My computer has decided to  assign a drive letter to what I think is my system "invisible" partition on C. It has assigned it drive "i". I am also constantly getting a popup error saying that I have low disk space on that drive. I never created a drive i. I have plenty of disk space available on my four drives.
Why is this showing up as a drive letter all of a sudden and how do I get rid of the problem?low disk space

Hello to all,

I took over a server from another IT company and I need to increase the partition size. IT has the following:

  • RAID 5 (yeah, I know, I know)
  • GPT
  • UEFI
  • One partition for OS and Data (C: Drive) - 3.7TB
  • Server 2012 R2

My question is: I need to add more disk space and I purchased a 2TB HD to add to the RAID 5 Array. Will I have any issues? The system has been operational without a hitch for the past 2.5 years.  Thanks for your input. See graphic below:

If you use a VIF - I understand you can attract all your S3 traffic over the Direct Connect circuit instead of going to the public internet. Is the full set of addresses to be used for S3 published anywhere so that we could create the right set of BGP filters to make sure that only the desired S3 traffic gets attracted to the Direct Connected instead of just going to the Internet?

Currently the path from our internal hosts to S3 storage is via the Internet to Amazon public IP. The goal is to get that traffic to go over our Direct connect circuits. I believe the method is using VIF and then those addresses get advertised via BGP over the DX. I want to filter those routes so unintended traffic doesn't go over the direct connects.
We are setting up our First Virtual enviroment in Hyper-v.

We want to know if its best practice to have the file server separate from the DC.

Or should we just create a C: drive and a separate Partition E: on the DC for the shared folders.

we do have enough licenses for 3 VM's.

Also we would like to know what is the difference between raid 5 and 10 for redundancy?
I have on one of my exchange DAG servers.

F drive which is mount drive for various DB's

I saw alert Mount Drive Monitor is more then 95% full on

I am attaching the alert. is it because one of the db's have only 5 % space.
To create vMotion between two VMware server under shared storage, do I need to put these two servers in the same clusters ?

For the shared storage, does it mean that both servers access the same iTarget (ie. same IP and port number ) ? How can same iSCSI target been shared between two servers ? Will it cause data inconsistency when two servers need to write data at the same time ?

In vCenter 6.5 appliance, 2 Dell R710 hosts with 6.0 i created a distributed LAG for iscsi. I added the hosts and their NICS to the group.  I then configured the iSCSI port groups to use the LAG as Active Uplink. After that, it seems that the Host Storage Adapter no longer can make an iSCSI connection.  I am confused on where the problem is and what to do next.

HP DL380 Gen7 - RAID 5 - Array disks seen, when trying to install server 2012 it shows me 3 partitions (which i though is odd) but will not allow me to delete , format or install windows?

Hi ,
I have a netapp share which shows online but is not visible to the user. I tried to give the permission but its saying invalid user/ group.

the user and groups are existing and correct but still showing error. I think it is not able to extract user or group information from domain controller.
I am trying to find a raid 1 card, with at least 4 ports,  for win 10 pro that emails alerts. this machine will be headless and remote, so i need an email to be sent if it has some kind of problem with raid or smart etc.

Anyone got any ideas? my great hope, the Adaptec 2271700-R 6405E  does email alerts on linux, but not on windows!!

All help gratefully appreciated.

the problem is there is CIFS server which authenticates to AD. one day it was not authenticating to any DC in site

 we just hard coded to 1 dc and there was a password mismatch occurred we tried to reset it and it worked

 my question is when hard coding to 1 server password mismatch occurred but otherwise it was not giving password mismatch when authenticating to all DC before.

Attached RCA provided by storage team but I need to provide RCA  FRom AD team?

Why CIFS was unable to Authenticate to users?      Because CIFS servers relies on AD for user authentication
Why AD was rejecting the CIFS server?       Due to net logon errors and CIFS server account password mismatch

Why netlogon and password mismatch errors?      To be filled by AD team
Note: - NetApp has confirmed that the CIFS machine account password is saved in AD, Which storage Admin don’t have any control from filer end.
o      Root cause should be filled by AD team since NetApp has confirmed that the CIFS machine account password is saved in AD,
I have a new Windows Server 2016 Essentials with Windows Server Backup and C: and D: drives are configured for Shadow Copies. Total size of hard drive is 2 TB. We are using about 700 GB.
Everyday it keeps losing big chunks of space. After a week I will only have about 90 GB left. A reboot clears everything out and it'll go back to 700 GB. But after another week, it will be the same issue, about 90 GB free space left.
I couldn't find the data / logs that's being used. It is not showing in Windirstat. It only shows 700 GB in total. Please assist on what things I should try to address the issue. Thanks.
We are looking to replace some of our Dell Precision laptops that are used to run Autodesk Civil 3D.  Would having SSD's in RAID 0 make it noticeably faster when opening and working on CAD files over the network?  Not sure if the cost is worth the performance boost.


I would like to build out a VMware Site Recovery proof of concept with LUN replication. I have a client that is running ESX vCenter 6.5 with EMC storage at present and i would like to get a test Rig up and running that would allow me to build somthing out on a very simple scale while mimicking what is in place. Does anyone have a suggestion on hardware to build this out?

My root folder has 'James' and 'Roslyn' Folders.
Can I partition her own virtual cloud? Is 2 folders okay? We both have Macbooks

I am looking for a dock that reads old IDE, Ultra IDE, and also old smaller laptop HDs as well as any type of SATA HDs.  I would prefer one with a USB 3.0 connection.  I've looked all over and haven't been able to find someone that offers one.  One other option that I just thought of would be to use some type of converter with it with one end of the converter going to the HD and the other end going to the dock.  Example old IDE drive connected to the converter and then the converter connected to the dock.  Please advise if you can find a dock that will connect them directly with the dock and if there are converters available, and if so, will they work with a dock.
Can two Hyper V Hosts be configured to see the same shared SAN storage like vCentre does for clustered Esxi hosts ?
Source Path Too LongHi,
  I have a weird situation. I have a folder "C:\Data\Invoice\Backup" and in it, I have so  many sub-folders created by ROBOCOPY.
  At first I wanted to simply delete the folder by clicking [Delete] button, but I keep getting this error message about "The source file names are larger than ...".
  I googled this error message and found an article where the author suggested that I rename all these sub-folders to 1 letter length and delete the folders afterwards.
  I followed that suggestion and that is the reason why you see so many 'a'. It was somewhat effective, but no all of the files are being deleted and it is taking too much time to rename folders.
  . When I run a DOS command "DIR /s /w" to list all the sub-folders, I see the following:
 Directory of C:\Data\Invoice\Backup\a\a\a\a\a\a\a\a\a\a\a\a\a\a\a\1\1\1\1\1\1\1

Hi experts,

I am using Microsoft Azure, which comes with my Partner subscription. I am only using it to set up simple storage under the $100 monthly limit to use with Veeam. The problem is when I set up a simple storage, Veeam does not recognize it during its wizard. If I set up Azure to run the storage as a VM network, it does work with Veeam, but it is too costly, and it is complicated.

Basically, what I am saying is that I am rather clueless when it comes to working with Azure. I am not sure if I am able to contact Microsoft for support; that is doubtful. If someone understands my question, then possibly it can be done here. If not, I may need help one on one remotely to set Azure up properly.

Cant consolidate snapshots due to insufficient Disk Space!

Vcenter 5.5

I ran a comvault backup on a 11TB vmdk and did not realize i did not have enough space and comvault forced the snapshot anyway and now my 11TB Datastore dedicated just for that vmdk doubled in provisioned size to 22TB!  
Insufficient Disk Space
I have tried the steps in Hancock's link here

With no luck :(  

The VM is powered off and i tried migrating it to a 12TB lun and it took almost 24 hours and got to 93% and then the task in vcenter just disappeard! no error or message!

Im guessing the 12TB lun was not big enough, but then why would Vcenter allow me to even start the Storage migration task?

anyway, I really need help on this one i am trying to avoid having to increase the 12TB lun to 23TB just to migrate the vmdk

Also what ever will be the fastest solution would be ideal.  I am worried i might of corrupted the data too :(

please help

I have 3 JBODs that I use for SOFS, in each JBOD I have 4 SSD's

Over the weekend I rebuilt the storage and thought I was extremely unlucky as 2 SSD's seemed to have failed.

Because of this I put of rebuilding the storage, however I have come do it it again tonight after adding 4 more SSD's so I had 2 hot spares.

I needed to move some of the SSD's into different slots to accommodate sizes etc, however upon rebooting 3 more of the SSD's are now saying they have failed.

What could be causing this, is there any way to troubleshoot the disks? I am having major issues with it as all my Hyper-V hosts are currently running on local blade / rack storage.

ANy help is appreciated, I am tearing my hair out over this!
Can we run vSAN and SAN on the same ESXi 6.5 hosts? Different cables will be used.
I know it may not be advisable, but will it function? Thanks.

RAID 6 is just fine for a virtualization stack. Many questions answered here: Some Hyper-V Hardware & Software Best Practices.

Two RAID 6 logical disks: 75GB for host OS and balance to guest data (RAID 6 6x 900GB = ~3.5TB)

Once the host OS is in set up the second partition and once the Hyper-V Role is set up make sure to set the configuration and VHDX file setting to that partition.

I believe in order to setup each RAID6 logical volume it requires at least (4) drives.  So, how does the above recommendation make sense.  I am just trying to understand the premise.

Are we saying, setup  each RAIbD6 logical array with (4) 600Gbs disks which would provide approximately 1.2TB of storage each.  That does not make much sense to me if that is the case.  Placing hyper-v os on the first logical disk use no more than 100Gbs of storage.  Trying to make sense of this response.
I looked at the following article about RAID6 logical disks:
I need to configure a RAID 1 mirror on a Dell PowerEdge 720 server. There is already a RAID configuration that we do not want to touch. My plan is to put 2 drives into 2 of the 5 empty bays, then boot to the bios and configure a Mirror without touching what already exists or jeopardizing the data. I need to put together step by step instructions for our Change Management team. All advise is welcome and if anyone has any screen shots that actually includes RAID 1, I would appreciate it. I have only found RAID 5 examples online. Here is what I have so far.

1. Shut down server and power back on until PowerEdge Expandable RAID Controller BIOS is visible and press CONTROL-R.
2. Make note of current configuration and take photo if possible
3. Repeat step one and add 2 new physical disks to bays before server boots back up, then press Control-R to get back to BIOS.
4. Look to see if new physical disks were discovered and select Add New VD
5. on the next screen select RAID level RAID-1
6. check boxes next to the 2 newly discovered physical disks
7. On the Virtual Disk page tree view, select Virtual Disks > <disk_name> and press F2 to open the Operations dialog.
8. In the dialog, select Initialization > Fast Init > OK.

So am I on the right track? I am doing this all thru GOOGLE. I am not located where the physical server is and I will not be able to shut it down and review until I get the time window that the server can be down. I want to be as prepared as possible
How do I upload (attach?) file to a question? I have clicked Attach File, Choose File and Upload File. No Go!!
