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 guys

I'm doing a document to prove that we need a cluster environment for our virtual machines, as we have only one IBM X650 M3 hosting a load of virtual machines at our datacentre. There is no SAN either. All of the disks being used are internal on the actual X3650 which I believe we have around 14disks. I'm about to find out what sort of RAID has been set up.

I am making the documentation simple for board/management, but wanted to include 'what's wrong with his scenario' to show the sort of problems that could go wrong.

The current X3650 M3 has dual power supply, so that can't be a reason. Storage though may be an issue as if more than two disks die, we would lose all virtual machines that are business critical.

What other possibilities are there? Faulty Ram? Motherboard dying? Faulty RAM?

Thanks for helping
I have a 2TB Apple Time Capsule (Model A1409)

4th Generation

I have a MacBook and when I plug in the drive into a USB cable (w/ TM powered on)

I do not see any icon appear on Finder.

What steps do I follow to:
1) wipe the Time Capsule
2) verify it's been cleared

hi experts

is this the correct answer

VMkernel is a virtualization interface between a Virtual Machine and the ESXi host which stores VMs. It is responsible to allocate all available resources of ESXi host to VMs such as memory, CPU, storage etc.

or this

The VMkernel networking layer provides connectivity to hosts and handles the standard system traffic of vSphere vMotion, IP storage, Fault Tolerance, vSAN, and others. You can also create VMkernel adapters on the source and target vSphere Replication hosts to isolate the replication data traffic.
Is there a ELI5 (explain like I'm 5) for this process?  I'm not looking for a software recommendation.

I searched offline storage table (OST) and read that it "is an offline Outlook Data File used by Microsoft Exchange Server that enables users to work with their messages and mail data even when access to the mail server isn't available."  I also read a lot of content about OST and PST software.

Why would a person work with their messages and mail data even when they can't access a server?  What kind of work is a person doing that this is even necessary to do offline?
Any ideas what is causing the below weird issue since
I would like to see all folders when doing the
below step #3 and #10 ?

 1. login to Windows 2012 file server as "admin"
 2. open local C:
 3. see four of the five folders I created
 4. type "C:\hiddenfoldername" to see the hidden folder
 5. check to make sure above folder is NOT marked as hidden
 6. open "Server Manager, File and Storage Services, Shares"
 7. click "Tasks", select "New Share"
 8. select "Type a custom path"
 9. click "Browse", select "C:"
10. see four of the five folders I created
With reference to the attachment that report the slide of actual occupation of my vtl, can you have a detailed report of how and from wath is occupied with script tsm ?
My understand in write-through is that the controller puts the data directly to/from memory where as write-back lets the CPU do it. Is that correct?

   So neither method has anything to do with lost data due to a power outage? Only a cache backup (or a UPS) can save you there?

   So if you spend the bucks on a cache battery backup don't you still have the possibility of losing data that is in the cache of the hard drives?
Hi - hoping someone can help - We have a Dell Poweredge 110, RAID 1, Server 2012. We rebooted the server this morning and it came up with a message (see attached pic) about "Integrated RAID exception detected: Volume (HD1:079) is currently in a state DEGRADED - Enter the Dell 6gbps SAS Ctlr Configuration Utility to investigate!" First off, how do I get into the controller when it boots? Second, I'm going to pick up a 500gb HD, but need to know the best only way to install the drive (and to tell which one is degraded), is it hot-swappable? Do I just take out the hard drive and put the new one in? If I need to go back into the controller, do i need to add the hard drive there? I of course want to get this server back online without screwing up the RAID config. ANY help with this process would be appreciated!
Hi all.
I had a working setup but after the failure of my single virtual ESXi server (WMware work station, deploy ESXI. Install vSphere and add the virtual ESXi server), i have problems.
Basically i cannot add a data store to the ESXI server - it doesn't see anything. I've done this more than a few times previously but wanted to get my logic checked. Here's my setup
Storage host is 2012 R2 physical. VMware work station is installed on the same server.
1. I added iSCSI target (windows on the same s2012 R2 server) and included the IP address if ESXi as the initiator.
2. Created iSCSI target making sure the initiator was correct.
3. From ESXi i can ping the iSCSI target server IP address
4. In ESXi and storage adaptor i choose dynamic target adding the IP address of teh Windows server.
5. If i rescan adaptors and then try to add the dataastore it simply doesn't show up as an option.

It seems VMware is an unforgiving beast and that when something goes wrong, after it was working, you have to trash the lot to get it to work. Any tips appreciated.

Got a dell laptop from 2008. it doesn't boot.  Took out the hard drive.  put it in external dock to a win 10 machine.  Made 'unusual' scratching noises and an E and F drive came up. Couldn't browse them.

Crystal Drive info didn't see the root drive.

I put it in the freezer overnight.  

No scratching noice noise now - I can browse the recovery partition.  Windows shows an F partition but can't browse it / click on F and windows says F:\ is not accessible the parameter is incorrect.

Any thoughts short of a clean room type of service?

install it internally to a PC?
Booting in linux?

Crystal Disk info data is attached - takes a few minutes after clicking on the drive to get info

Windows disk manager says F drive is RAW.  E drive (recovery partition) is NTFS Healthy

I guess a partition recovery software.
On a Dell Equallogic SAN, we have two VMWare ESXi Hosts and each have one clustered Win2016 servers, with SQL2016.  All had been working fine, but now get the attached error, even though both servers are connected to the SAN volume via iSCSI.

Any ideas where to look?  Please note that the servers are connecting on IP address to the SAN, not on CHAP.


Hoping someone can help in a hurry. Just taken on a server consolidation and found a failed disk this weekend.

I really need this to run production for a few more weeks while we are migrating to new kit. It is out of warranty and I can't quickly find an exact 1TB Enterprise SATA 7.2k drive to replace it with.

I have a 2TB Enterprise SATA 7.2k from a different manufacturer. Can I swap this with the failed disk and have it rebuild onto the new 2TB disk (I realize I lose space but that is not a concern)

Any issues or gotchas I should know about? normally I would prefer to mirror two two of the same (I would gone with a higher raid in the first place...) but if this get me out of trouble it will all go on a new storage array in a while.
During a render computer stopped responding and restarted. The RAID now refuses to mount.  Disk Utility sees it, won't
respond to requests to mount.

Is it possible to recover RAID-0?

External box connecting via USB.
This may be very very easy for experts, but I need help with this one.

I am familiar with the process of setting up an EqualLogic for iSCSI storage via a standard VMware switch, and having dedicated 1Gb nics, on individual esxi servers... we have since upgraded to a VxRail appliance that has 4 nodes with two 10Gb nics each, and we are using the VMware distributed switch and VLAN's, since we no longer have 12 dedicated 1Gb nics to work with.  This is my first time I am setting up an EqualLogic that also has two 10Gb nics into our distributed VMware switch on it's own VLAN and I think I have it setup but would like to know if there is any documentation on doing this so that I can check to make sure I have done this correctly and have it setup up properly before we start using it and putting data on it.  Thanks!
there are 2 mailbox servers which are on same esx host.

one shows outdated NIC and storage driver the other shows none when I run best practice analyzer.

I am attaching snapshot of both server config, is there any difference

I am using VMware Workstation 14 and I have a virtual hard disk .vmdk with C drive having only 40 GB free space.

Is it possible to increase the C drive size in the .vmdk VMWare Workstation 14 version .vmdk virtual disk file?

Please reply to this question asap.

Thanks for your support.

Seems like every USB I buy is formatted to FAT32 so only 4GB of (Whatever) is available.

When I reformat as NTFS I pick up all of the drive space

But copying into the USB is much slower.

What is the best remedy?
We had a raid array problem on our ESXi box running our 2008 r2 PDC with exchange and had to restore to another ESXi box, a 5 day old backup, We are now getting:

I have an HP Microserver Gen8 which is failing to boot. It has an SSD boot drive (WIndows 10) and 4 SATA drives in the standard bays at the front.

I've got hold of an identical Microserver Gen8 and what I'd like to do is move all the drives across to this server which works fine. I've attached the SSD drive but haven't put in the SATA disks as yet. I've checked the BIOS and it can see the SSD drive, so that looks good.

The issue I have now is that the Gen8 server has a built-in RAID controller (Dynamic HP Smart Array B120i RAID support) and I'm pretty sure when I originally set it up, I didn't setup any RAID at the hardware level, so they were just a bunch of disks. In Windows 10, I used storage spaces with parity for software RAID.

So, my question is - can I put the SATA disks in the drive bays and boot up and it will see the drives / Windows Storage Space as normal or do I have to do anything in the HP provisioning beforehand? I remember that original server that fails to boot also uses the same B120i RAID controller).

I don't have a backup of the data that's on there and I can download it all again, but there's a lot of it (6TB), so I want to avoid having to do that.
We ran Best Practice analyzer test on one mailbox server which is VM

we found Outdated NIC and storage driver.

what should be checked on VM level here? which ESX hosts or anything.



Type Celeron
Installed Qty 1
Clock Speed 1.5 GHz
Number of Cores Quad-Core
Processor Number J3455

Max Turbo Speed 2.3 GHz

... what does the "Max Turbo Speed" mean?
Afaik there is just the Clock Speed, can I run the Synology in turbo mode or clock it to 2,3 Ghz ...?

Thanks for your input.

I posted this some time ago:

have a DS414 now, didn't buy a new one yet, since it was quite some money to spend for "just a home lab".

Now I've read that the Synology DS918+ (reviews are pretty good):
*only costs 550 Euro
*has quad core 1,5 Ghz, https://www.cnet.com/products/synology-disk-station-ds918-plus-nas-server-0-gb/specs/)
*also runs 16 GB (about 150 Euro for 16 GB)
https://forum.synology.com/enu/viewtopic.php?t=136028 has SSD cache built in
*is only using 100 Watt
*has SSD cache build in (without the need to buy an extra card)
*can run virtual machine manager: https://www.synology.com/nl-nl/dsm/packages/Virtualization

My current NAS = DS414 with 4 disks (Seagate Green -no SSD- basic disks) of 3 TB in RAID5 (still half of it is empty).
So I'm thinking of buying this DS918+ and buying 16 GB for about 160 Euro
=> crucial-8gb-ddr3l-1600-cl11-sodimm

Not sure about the SSD cache: would I need it and if yes which one and how much storage (128, 250 GB ...? they are quite expensive):

As mentioned, it is only for home use (1 user and running a vm from time to time), maybe other users will connect remotely and I might run a website on it.
So I'd spend 700 Euro for this upgrade. That's about the max I wanted to spend.

So please …
