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 was off and running with what I thought was a great solution to my backup problem. Unfortunately, I didn't consider reboot.

My "Virtual Drive" was assigned drive "D". Following a Windows update and reboot last night, Drive D is no longer visible. My Storage Spaces is comprised of 2 8TB external drives.

Is there a way to recover from this without starting over? And why would anyone even use this feature if it won't survive a reboot?

Ideas anyone?

Hello Everyone,

A general question about VMware 6.0 best practice re. total storage group size available.
We have an EMC VNXe3150 SAN with 4 Storage groups all around 1.8 TB of usable space. Some of them have a lot of space left whilst others are down to what I will call bare minimum, e.g. 70 GB and 100 GB out of the total 1.8 TB. I did not use the rest of the space as I figured it is best to leave a bit for the system, but that is based on my experience with physical servers. I did get a warning from the VMware about space running out and so I left it. Should I leave more? Oh and just to clarify the 3 ESXi hosts have disks as well (we do not host the Linux o/s via USB or SD card, rather built in disk) and they are around 130 GB and 80% free so I am talking only about the actual storage available from the attached SAN to the VM's through the 3 hosts. Finally we always Thick provision (Eager Zero) so all space needed is always assigned, i.e. I don't over provision so the space left over should never be needed by a VM for space.Thanks in advance!
We have Yosemite backup going on our Ultrium 5 tape drive, yesterday we tried to restore some file from it for first time and initially it showed the file on the tape and now under the devices it says Invalid-Device not ready whereas the tape drive is connected and checked the connection using HP utility and it showed all good. what could be the cause to this?
If the USB Flash Drive is big enough, can you partition it? Example, make a USB bootable, have a folder with documents etc?
Building a new vcenter environment with the below components

1x UCS 5108 chassis with embedded 2x 6324 Fabric Interconnects (each interconnect has 1x 40G QSFP, 4x 10G SFP+, 1x 1G)
8x B200M4 blades (dual 10C CPU) . Each blade has a VIC 1340  (dual 4x 10Gbps ethernet)
1x Nimble CS1000 with 10GbaseT ports (dual controller)
2x Brocade VDX6740T-1G (48x 1G/10G ports + 4x 40G QSFP ports)

What would be the recommended design for performance and high availability?

The main difference with most designs is that we are using the Brocade VDX switches instead of Nexus.
Hi, we are deploying MS Exchange server (VMs) inside a HOST using VMware ESXi and finding a way to get Redundancy (High availability) for Email service. Can anyone suggest any method?

We will use 1 SAN storage + 2 SAN switches as well.
i have a veeam Job which backup 6 vms(jobname= job1). Sudenly this Job not working any more , after that i cloned this Job (jobname= job1.clone) and work good at the Moment.
but still exist on the NAS storage , .vbk and vbr files. they are prox :900 gb .of Course i would like to use this space for job1.clone Job.

i changed restore Point under job1 and deleted part of vbk,and vrb. But still there is data which i cant delete manually.

Please help to delete These old files.

Thanks in advance
I have installed Server 2012 R2 and created 2 VMs (VM-1 a DC and VM-2 a member computer) both running Server 2012 R2. The test bed server I am using has 2-120 GB SATA SSD for the OS in a RAID 1 and 2-1 TB SATA hard drives in a separate RAID 1 configuration for the data storage. They are controlled by the Dell PERC card. I would like for the member computer, VM-2 to be able to access the data volume and see it as just another hard drive with a drive letter. This is a work in progress for me as I am learning and reading articles on how to do this. As a side note when I created the Hyper V folder (300GB) to hold the VM files, I was able to see the data volume from the Hyper V host and located the Hyper V folder there. I was not sure of how much space the VM files would require as the system space requirements grow. I would have preferred to locate them on the SSD...however.
On the member server VM-2, SQL Express, RDS and a business management application will be installed. It should have about 500GB available. All of this will be required to be backed up nightly. Your help and comments are appreciated.
Thanks - HBee3
Have a desktop, Dell XPS Studio, that came with 2 1TB hard drives set up as Raid 0. One of them is now failing & it won't boot, get the error message "AHCI Port0 Device Error Press F2 to Continue". F2 brings you to the BIOS setup and it's just stuck in that loop.
The client said it boots up every now and then but i've tried it at least 20 times & no joy so reckon it's after getting worse.
Any way of extracting the files from this as they've no backup?
While I'm able to monitor many factors, I'm hitting road block when looking to determine which VHDx is causing the most IO/queue within an SMB share.

We can see which shares are heavily utilized over time (custom built monitoring), but not the cause within the share. I end up running storage live migrations to spread load over other shares, but it would be nice to know which file(s) (VHDx) are causing the most communication. Anyone break through this barrier? I'd be very curious.

Again, I'm aware of the ability of perfmon to see SMB shares, but this is the share. I'm looking for files within the SMB share. Thanks in advance for any/all help!

I was building a small-time home-brew server today from parts laying around and I have a build that is practically brand new. Never used but once or twice. But everytime it powers down, I have to reset CMOS for it to power back up. Aside from that, it works well. I can soft and hard restart it. my RAID array is fine. But if I power it down, I need to reset the CMOS to start it back up.

Any ideas as to why this happens?
I'm trying )remotely) to help a client check things on a RAID cotroller

I have downloaded the Intel RST Raid Ctrl sofwtare from here but it only shows me the CDRom disk

Is there a sofwtare that can display the RAID config under Windows Server 2012? or do I need to boot into the RAID controller?
I have a server 201 vm residing on a 48 drive SAN that is RAID 10. I am wondering if it is worth configuring the vm OS disk for mirroring? What is everyone's thoughts on doing this? any benefit/drawbacks?
 I have HP DL360 G5 server with P400 SAS RAID Controller with five 147GB hard drives. It is running VMWare ESXI 5.1. One of the hard drives failed and it showed in amber color. I replaced the bad hard drive in timely manner, but I like to be able to monitor RAID status in a graphical fashion. Beside the VMWare box did not even beep when the hard drive failed.
 In VMWare box, I have several VMs - Windows 2008, Windows 2003 and XP desktop IS.
 I can also utilize a separate workstation PC (running Windows 7 or 10) to run RAID management software if necessary.
 Can you guide me into the right direction?

I recently purchased 2 of Seagate's newer releases - Seagate Expandable 8tb external drives to back up my media. I was using Amazon Drive, backing up to the cloud but their prices increased by a factor of almost 10 so I started looking for alternatives.

My Backup software (iDrive) only looks at one drive at a time which my media won't fit on so I'm looking for a "Volume" solution where you can group multiple backup drives but have it "appear" to Windows 10 as only one drive.

That brought me to the subject of "Spanning" drives. A term I was completely unfamiliar with, but from it's description, sounded exactly like what I was looking for so I thought I'd give it a try.

Using Disk Manager:
Step 1 in the process is to delete the existing volume.
Step 2 in the process is to right-click on the volume and select "Spanning".
Step 3 in the process is to select the drive(s) you want to include.
Step 4 you are presented with a screen informing you are about to convert your discs to "Dynamic". It's not optional. You either convert or cancel the process, so I selected to continue.

I then received a message the process failed. "Devices don't support this action" or something along those lines.

From that point on, my drives became inoperable. Device Manager could see them but Disc Manager could not. Nothing I tried would bring them back into Disc Manager. Even using the Cmd line approach, they were not identified.

I have 2 new drives coming later in the week but for …
Hi All,

Is it a good practice to build the azure backup server directly on azure and then backup on premises servers to the disk that is on the cloud connected to the azure backup server?

thank you in advance,

I am getting this error in HP P410I smart array controller. I have replaced a faulty drive out of 6 with raid 5

Error 785 Background parity initialization is currently queued or in progress on Logical Drive 2 (2.3 TB, RAID 5). If background parity initialization is queued, it will start when I/O is performed on the drive. When background parity initialization completes, the performance of the logical drive will improve.

Please help me. attached the diagnostic report.

Hello Experts,

Does anyone know the procedure for backing up the Raid module configuration on a Dell MD3260?  We are replacing the Raid module controller battery and have it listed in the steps to save a copy of the configuration file in the MD Management console but it does not have any further instruction.

Thank you,

Hello all :)

We are running an IBM Blade S with VMWare and Server 2012

Under disk management on our file server one of the disks has a status of Healthy (at risk) with a warning exclamation.

There is the option to reactivate but that doesn't do anything.

The disk and its contents are available.

I have checked the AMM on the blade and there are no disk errors or warnings that I can see

What could be causing this and what is the fix?

I have three virtual servers running on a pretty hefty machine among like 5 other physical machines. each virtual has its own NIC and it plugged into one of our three switches somewhere. We are having some major slowness on two of these virtuals as far as transfer speed across the network. The virtuals are all server 2012 R2 and all are located on a raid 5.
    My first thought is that we dont have enough throughput between our switches which are Managed Cisco Switches. im about to use LAG to connect these together with increased throughput. Im seeing less than 200MBps to the slow ones and well over 300 up to 600 at least for the rest. i have seen 85 MBps on one virtual and unfortunately that was our DC. i will be putting all the servers on the same switch soon which should not limit throughput as much. is there any settings i need to look for in HyperV manager that could impact this.
   Again all my virtuals are on the same physical machine in a Raid 5. each Virtual is connected to its own NIC as well. the Server and the Switches are all less than a year old. Im using LAN Speed Test from Tutusoft for my testing and we test from multiple servers to another server to have multiple speeds to look at
I'm having to help on a project to push new Windows images to about 250 computers in a short period of time.

I don't care about saving any data, as the user profiles are saved on network storage. Nuking it from orbit. Glass deserts.

While I can do PXE boots for VLANs or Boot CDs across them, I'm curious about running LiteTouch from within Windows, as can be done for application installations. However, since I'm having to format the drive, I'm running into issues where it appears that things are not being written to, as they're currently in use.

Before I give up and go back to having to set up a bunch of servers for the various VLANs, is there anything out there that would be applicable on how to set this up? All the info says it'll work...on XP and 7, and MDT2010 or 2012. Not on systems with 10, UEFI, and MDT2013.
Hello every one,
I had a problem with 2 VMs which needed to consolidate. It was not possible, no snapshots was shown in Snapshot Manager. Thinks I tried:
Snapshot (without virtual machiene`s memory), wait a minute, Snapshot (without virtual machiene`s memory) but “Quiesce guest file system”, wait a minute, in Snapshot manager “delete all”. I also tried this with VM powerd of. No success.
Restart VDP. Consolidate. No success.
Repeat first step. No success.
Restart services on the ESXi. Consolidate.  No success
Shutdown all VMs on this ESXi, set ESXi in Maintenance mode, Restart ESXi. Now I was able to consolidate the HDDs.
Power on all VMs on ESXi, last VM was VDP…not
Suddenly, a wild new Problem appears :( …
Starting VDP goes to 52%, then error: "Failed to lock file"
“An error was received from the ESX host while powering on VM VDP01.
Failed to start the virtual machine.

Cannot open the disk '/vmfs/volumes/5500460b-6c9e52a8-6655-14feb5c8097d/DC01/DC01-000002.vmdk' or one of the snapshot disks it depends on.
Failed to lock the file

Module Disk power on failed.

Cannot open the disk '/vmfs/volumes/550046ba-c3cdb30c-e5f6-14feb5c8097d/FS01/FS01_1-000002.vmdk' or one of the snapshot disks it depends on.
Failed to lock the file

… Yay …

I took a look in ESXi Datastore / storage where those two VMs are stored in. There is still a “VM_NAME-000002.vmdk” file. It is older than the “VM_NAME.vmdk” file.
Trying to consolidate again completes instant, but …

We had some issue with esx host and all VM went down, trying to figure it out the problem.  Here is the esxhost output

esxcli storage core device list   |  grep  -i  status
   Status: degraded
   Thin Provisioning Status: unknown
   VAAI Status: unsupported
   Status: degraded

Why status shows as degraded eventhough all the VMs are up and running. This is local disk, but fiber channel status looks goood.
