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.

Hi all,

Is there an easy way to view who is using folder shares on a server. We have an older file server we would like to move the still in use data from and then retire.

I have Proliant ML310e Gen8 V2 server running Server 2008 R2 standard.   I want to run Windows 10 on it.  While booting to Windows 10 it stopped and said it was missing a media driver.   The computer has four drives in a raid array.  Could the driver that is missing after I hit "Install Now" on Windows 10 be for the raid array?  Any ideas?
Hi Guys,

We have an IBM System X 3200 M3 server with 2 x 500Gb hard drives installed.
The drives have been striped with RAID 0 running VMWare Esxi.

We now wish to install another 2Tb drive.

I need confirmation that the drive will be compatible with the server model, and that we would be able to install the drive, without interfering with the current RAID config.
I am not sure whether we'd be able to run 2 x separate RAID groups on this model?

Server model:  MT7328
Hard drive model:  42D0782      - IBM 2TB 7200 NL SATA 3.5" HS HDD
I'm attempting to expand our NFS/CIFS/Samba file server to improve bandwidth, as well as create HA data redundancy.

One of the big bottlenecks is I'm limited to a 1Gb network in the building.

I'm thinking of implementing a hardware load balancer into the works, between the server(s) and the building 1Gb infrastructure - under the theory that we can spread the final load for NFS amongst different physical network cables amongst the clients, the 1Gb swicth, and the servers. (see diagram).

QUESTION: Will this actually improve the NFS/CIFS bandwidth for the individual end users?

Suggested load balanced NFS/CIFS
ok, we have two Dell R730 servers with LSI HBA cards.  Those two servers are connected to a Dell MD1200 enclosure with 36TB of storage.

Server 1 was running ESX 6.0

Server 2 is running 6.7

I vMotioned the live VMs off of Server 1 over to Server 2 and upgraded Server 1 to 6.7

Both server are now running ESX 6.7

The problem is, Server 2 came up and while it is connected to the MD1200, the existing datastore does not show up in the list of Server 2 datastores.  The internal storage is there, and the IBM v3700 is there, but the Dell MD1200 didn't come back.

Now, Server 2 is connected to the MD1200 and all VMs live there.  I simple want Server 1 to reconnect and share that datastore, but I'm not sure what is going on.  

Can someone point me in the direction of making that MD1200 come back to Server 1 now that it's ESX is up to 6.7??



PS:  Reminder, Server 2 is connected to the Dell MD1200 and all live VMs live there and are on that host.  I just need my newly upgraded Server 1 to reconnect and share the storage.
I have a new customer with Dell T30 server.
- Unfortunately they purchased this without consultation
- The server only came with 1 1TB Sata drive
- 8GB of RAM
- Prior to us starting to work together my client decided they wanted raid10 redundancy
- They purchased 3 additional 1TB drives from Dell
- Enter me
- The server does not support any kind of onboard raid
- I contacted Dell and of course they do not make any raid controllers for the T30

Any one have any thoughts about either of these controllers as an add-on option?

Again it's aT30 so it'll be limited but trying to make some lemonade outta the lemons I've been handed :)
We have a Tandberg USB 3.0 RDX drive and media for backups

Some RAID cards I've been considering
LSI 9341-4i
Intel rs3wc080Intel

PS sure we can look at Battery backed , cache, onboard RAM, etc but this is just to get some basic redundancy beyond a single drive in their server.

Thanks in advance.
I have a hp z800 and want to setup esxi 5.5 on it as a home lab but i am not sure what kind of disks to purchase and how to configure the built in intel raid (is this considered as software raid? If so i dont think ESXI supports software raid and I may need to purchase a physical LSI - pcie raid hardware card)  so that vmware will be able to see my hard drives as a datastore. I will also be running esxi off of a usb thumb drive.

I also believe 2TB drive is the largest siz drives i would get (i know some of it gets lost but how many 2 TB drives would i be able to use and what would be the expected available size after setting them up in raid and what it the best raid configuration to put it into Raid 5, 10?

Thank You in advance for your time!
My computer started to give me blue screens for the first time yesterday, 3 times actually.  Today, same thing, I was able to get into windows, but it crashed 2 or 3 times, so I did a full restore from my backups about 4 hours ago, and so far so good, it has not crashed yet, BUT, my problem now is, besides my OS drive (SSD), I had 2 more drives in my PC, another 2.5" SSD and a 6TB drive, both already formatted.  
The bios sees both drives, but when I boot to windows, none show up.
I checked the device manager, nothing there, I checked disk management, they are not there.  I clicked on scan for new hardware in device manager, nothing shows up.
I found online to run the windows memory diagnostic tool, did that, restarted, and still didn't' show up.   I'm a bit puzzled.

Any other thoughts why the drives show up in bios, but not in windows, running the latest version of windows 10.

I wish you could help me with the following question about SQL Server and a performance problem I have:

Old Server:

I have a closing and opening process on my system that takes about 11 minutes.  

My storage is:
3Par 7200.
Raid5 15K SAS ( 35 disks)
Block Size: 128KB

IOPS  can deliver as maximum for Reading and Writing in a native way:  IOPS 9950


The server has the version of SQL Server 2008 R2 Enterprise Windows with 2008 R2 Enterprise. It has 2 Processors with 16 Cores but the SQL Service only recognizes 16 cores.  

I haven't been able to capture the IO statistics or specific time in the processes because this process has many cursors and makes the SQL Server crash. Neither have I been able to capture the execution plan by the cursors that the process has.

New Server:

The same process takes 8 minutes but writing IOPS rise from 800 to 2000. Reading IOPS decrease from 1000 to 400.

 3Par 8200 with the following features:

Raid5 SAS of 10K ( 10 disks)   IOPS 2568Max. For CPG FC_Raid5_SinAO
400 Gb SSD disk arrays ( 8 disks)  IOPS 100239 Max For CPG_SSD_Raid5
Block Size: 32KB

IOPS can deliver as maximum for Reading and Writing in a native way: IOPS 2568
IOPS with AO 30,000 Max Reading ( The writing processes depend on the Native IOPS of the CPG used in this case FC_Raid5_10K )

The server has the version of SQL Server 2016 Enterprise Windows with 2012 R2…
Hot swapping drives Risk

I am used to see Engineers swap mirrored drives off the servers. They take the bad drive out then put it back to reseed.

However, in some situations both mirrored drives have green lights which meeans they are good and some engineers will take out one of the mirrored drive, for instance just to read serial number.  In this case I was wondering if it is risky, since the drive taken out might be in the process of getting Data written to before it gets mirrored to the other drive.

Any idea on that ?
have an old 5.5 esxi host (same vcenter) Out of need due to resources on another host I had to build an exchange server on it.  It didnt' have much in the way of diskspace and because of the swap file taking up 50gb I only have 400mb left on the local storage, my mailbox databases reside on an iscsi volume. OS on local.  I can't even backup because of the low space on local. I want to move that OS drive to the Iscsi Volume. Is it as simple as turning VM off, migrate and powering on?
Dell PowerEdge 840 -- Server 2008 Standard - PERC 5/i RAID controller ----- does not reboot after Windows update.

I accepted the MS Update yesterday and when the server rebooted, it did not come back up.   It appears that either the RAID controller is bad or the configuration got toasted.   I am a fairly non-tech person with just enough knowledge to understand what someone is asking me to do and then performing it.   This server is our SQL server and has a database on it.   Our office is 'dead in the water' until this can be resolved.   Can you please help me?    I’m hoping that there is a simple way for the RAID controller to be instructed to ‘grab’ the drive configuration off the drive itself and then we’ll be back in action.   I called Dell for telephone support, but they told me that it would be $1,000.00 for 2 hours of telephone support.  Ugh!    We do not have that funds available.

Would appreciate your expertise!
I need some help to know where to start digging.

I've got two hosts (ESX) and they both have 10gig NICs.  They plug into a 10gig switch (ubiquiti).  

I'm using Veeam to migrate one VM from host one to host two and the speed is 48 MB/s.  Of course, I am expecting faster.

Now, my Veeam Server is a standalone server with it's own 10gig NIC, going into the same 10gig switch, so I thought maybe the traffic is passing thru the Veeam server and that's slowing it down.  Maybe it's the storage (since Veeam tells me the source is the bottleneck).  Of course, it dawned on me AFTER I started the move that I could have just moved it from one host to the other using vCenter, since the VM isn't changing storage, just moving hosts.  Stupid me...I don't wanna cancel it so I'm letting it run.  

This is also a good exercise for me.  I need to know where I'm weak.

Anyway, Where do I start?  

No jumbo frames turned on by the way.

I have 8 x 4TB SATA drives (hot swappable) and want to configure Storage Spaces for them but have been wondering if I should create two pools and each has 4 x 4TB with mirror or just one pool with 8 x 4TB with mirror. What is your suggestion?
I had this question after viewing NAS drive recommendation.

I'm looking for NAS recommendations. We currently have 2 Seagate NAS OS 4 NASes. They work quite well as long as they are on the same site we are backing up data from. However, we had one at a remote site so we could use it for offsite storage. However, we ran into an issue with the NAS throttling down during transfer. This would cause the transfer to take to long to complete. I wanted to buy another one but want to make sure not to run into the same issue.

Which NAS do you recommend? We will be looking to purchase one that will hold at least 8TB's of data and use Raid 6.
This is using a SPARC server hardware. This is using Solaris 11, with 2 VMs (using ldm). We used fiber-optics network-based SAN Storage, create LUNs, and allocated for 1 or more for individual VMs. We are using "ldm" commands to manage these VMs. On one of this VM - mcsat1, there is only 1 LUN allocated for the rpool. Now, we wanted to add-in one more LUN to form the "storage pool" (mirrored). After that, we wanted to remove the original LUN and use only the new LUN. Please see attached document for steps we conduct.

c1d3s2 is the new disk added in and kept, and c1d2s0 is the old disk and supposed need to remove. After the detaching, we do the system reboot. However, we faced a problem here - system failed to reboot, with the reason being "boot disk can't find". In this case, we already change the "boot-disk" with command - "ldm set-variable boot-disk=IBM2SAN2 mcsat1".

In "ok" prompt, we typed "boot /virtual-devices@100/channel-devices@200/disk@3" with attempt to boot the system up via this new disk was successful. If you see the document, this IBM2SAN2 is actually refer to "/virtual-devices@100/channel-devices@200/disk@3", booting "IBM2SAN2" failed while "/virtual-devices@100/channel-devices@200/disk@3" passed, why?

Thanks in advance.

I am currently using Veeam Backup and Replication for backing up my VMware VM's. I have several large VM's that are not in use but I want to keep stored in cold storage, preferably in the cloud maybe AWS or Azure. As of right now Veeam does not have a way of directly taking a specific backup of a VM and putting it into AWS. I want specific VM's to go into cold storage and then delete them from VMware.  

Is there any way (with Veeam or without) for me to backup specific VM's and put them into cold storage in a way that I could restore smoothly back into on premise if necessary?
We have VSAN configured @VC 6.5 configured with 8 Esxi  6.0.0, 4600944]Host , suddenly 1 host not responding and disconnected from cluster ?

Can somebody help me please. I have 2012R2 hyper-v cluster with two nodes and an IBM Storewize v3700 connected over SAS. I can't figure out how much free space there is in storage volume (I think free space isn't freed up on storage)

For example, in hyper-v cluster console, there is clustered volume "brzi" ("fast" in english) which corresponds to volume on storewize. It shows size of 1.50TB and free space of 676GB, app 50%.
In Storewize GUI, i have 1.5TB pool with 1.5TB volume ("brzi"), that is available to cluster hosts, and it's seen in the image above as clustered share vo .
But when looking in properties of that volume, free space doesn't match free space reported to the cluster (676GB). The files when selected from host, really takes only about 50%.
Storewize VolumeIt's seen as space is entirely used....

Thank you
Hi EE,

Today we had a sudden spike on our Flash Array Storage network, something was running for 4 hours and consuming 1 GB of throughput.
We have isolated the spike down to 3 servers (virtual Vmware boxes); these servers are dedicated SQL servers training and dev environments no much activity on them normally.
I have checked to see any SQL jobs were running they weren't and restores were occurring this time.

Any ideas on how to troubleshooting this issue as we don't want this occurring tomorrow morning?

Thank you.
we got canon C356iF II imagerunner
would like the scans to be saved in a certain folder that is shared and accessed via SMB.
we currently do not have a file server to utilize for such.
does this scanner come with internal storage that can be utilized for this, and it can be accessed via staff over SMB of FTP ?
