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.

we currently have a vswitch with 2 x qsfp NICs that we use with an Equallogic SAN with multipathing with 2 x vmkernel ports on the same vlan. Is it possible to add a second pair of vmkernek ports  to the same standard vswitch, on a different vlan, connecting to different san?

We have an 18TB VVol, and want to allocate 3 TB for the file servers. The rest of the volume will be used by other VM’s.

Can we create a 3TB volume inside the VVol so the file servers can use this space? Alternatively, shall we shrink the VVOL and allocate the space to the fileservers the free space?

Whats the best way to handle this as I know VVOLs work different to  VMFS

Hi team,

Is it possible to create a Microsoft SQL Cluster in a Nutanix HCI environment with two Virtual Machines if the share storage is unique for the three hardware nodes? In negative case, which possibility exist to implementing virtual cluster to Microsoft SQL Server in this environment? I looking for a HA solution because actualy the Data Base is in unique Virtual Machine with the problem entails in the time to maintenance the server without interruption in te productivity.

Best Regards,
Hi Guys,

I increased the storage on a VMWare ESXi 5.x server by adding another disk to the server.

I managed to expand the storage of the Datastore.

I am now trying to increase the disk provisioning space for the virtual machine, but I seem to be having some challenges.
I powered off the virtual machine, but the Disk Provisioning section stays grayed out.

I have a Samsung Pro 850 512gb SSD as my C: drive in my Win 10 system, that I calculated when choosing, would remain half empty after I installed my programs and I only use it for programs--data is stored on HDDs. Both Program and Windows folders = 43gb.

After some weird issues popped up and a noticeable lag in some functions, I found that the C drive was showing 21gb left of 476gb space.  

After scrounging around and sorting through 80% of the folders I found that the  C: > Users > ME >AppData > Roaming  folder is consuming 329gb of space and the culprit is Adobe. Can I delete any of the contents safely?
Hi Guys,

I need to increase storage on a VMWare ESXi 5.x server.

In ESXi 6.x logging onto the server, I am getting the option "increase capacity" under storage, devices.

I am unable to find this option in ESXi 5.x

Was this option available in ESXi 5.x ?
Dell Server Drive blinking green/amber alternately regardless of what drive in install in that bay..
I know this is suppose to be an indicator of impending failure, but why does it blink this way when I install a replacement?
I tried resetting the adapter to factory, and that worked for a little while, but then reverted to this behavior again.
I have another bay to use, but just curious if someone else had seen this before.
Thanks as always.

I have a server running Vmware ESXi on a Dell Power Edge R510.  It's setup with RAID with 4 10K SAS drives.  The capacity is 1.64 TB.  All 4 of the SAS drives have been recently replaced.  I'm not at all familar with Vmware as I've always used Hyper-V and other VM solutions.  There's only on VM setup running Server 2016.  Xeon X5675 (8 processors) with 48 GB RAM allocated to the VM.  The host has 64 GB RAM. 12 CPUs.  A software vendor (I'll call vendor A) recently upgraded their software on the server and it looks like they're using SQL 2012.  They have another db on the server that also uses SQL 2012 well call from vendor B.  There were a bunch of log errors from vendor B's database.  10 GB worth.  They cleared them but their storage benchmark said that the write speeds to the storage were around 22 Mbps.  On 10K SAS drives that seems excessively slow.  I've logged into the ESXi navigator and have spent a few hours going through all of the settings in there.  Is there a way that I can test if all four of the SAS drives are working properly?  Under Storage, Datastore01 and Monitor, there are a few lines from June 13th (nothing listing anything after that).

So I have a brand new server and a Server 2019 Datacenter license. Two small-ish drives working together in a RAID 1 will be for the OS. That will be formatted as NTFS and 2019 DC will be installed here with the Hyper-V role (and that's it!). Then ... I have 6 SSD drives working together in a RAID5 and the only things that will live on this drive are the actual Hyper-V VM files.

I've read about how ReFS has come a long way since it was released with 2012, yet when you format a data drive in Windows, NTFS is still the default. So I wanted to ask - who out there has embraced ReFS for Hyper-V? Should I keep it safe and stick with NTFS? Or should I use ReFS?

This drive will never be used for anything other than storing Hyper-V files.

Also: If I go with ReFS would there be any potential compatibility issues if, say, I had to migrate a VM from an older server (having only NTFS) to this new server (having only ReFS) or vice versa?
Hi All,

We are currently running a VMware environment with SAN as storage. We have two sites, production and disaster recovery. We are currently reviewing our backup site. At the backup site we have another VCenter, physical hosts with enough resources to run production and an equivalent SAN with double the production capacity. Volume replication occurs between the production SAN to DR SAN. We use VEEAM for backups.

We want to be able to use the DR site in the event the production site is unavailable due to disaster as quickly/easily as possible for all network services. Is it better to use VM site recovery or veeam replication. Should we continue to replicate the Volumes from the production SAN to the DR SAN? We also want to be able to recover single server very quickly, ie if our storage server got hit with ransomware we could simply roll it back to a known uninfected time.

Thoughts, suggestions and input very welcome.

Dear EE,

I have 1 Resource Group

1) Region9

In which i have three Azure VMs,
1) Test 1
2) Test 2
3) Test 3

All the above three VMs storage are in different Resource Groups.

1) VM= Test1 = Resource Group = Region 9
Storage Account Resource Group = LHR

2) VM= Test2 = Resource Group = Region 9
Storage Account Resource Group = ISB

3) VM= Test3 = Resource Group = Region 9
Storage Account Resource Group = KHI

I have created one another Storage Account with the following details.
Replication: Locally-redundant storage (LRS)
Account Kind: StorageV2 (general purpose v2)
Data Lake Storage Gen2 : Disable
Access tier: Cool

The main REASON to create above new storage is to perform Archiving of all the Three VMs
Now i have created New container in this New Storage.

Now, what next.

What should i do (STEPS, CONFIGURATION etc) to move all the three VMs to new Storage and make it Archive.

Dell T320 Server with PERC S110 Raid 1- has a degraded RAID 1 Array. no Read ahead / write through.

Event logs: Found this error - physical Disk 0;0;0;1 controller 0@connector 0 has failed.

When I use <control> C at boot to enter the raid setup, it states both drives are on line.

question: how do I remove the bad drive and rebuild the array......

we are reviewing our data leakage controls and there is a point in policy regarding uploading company data to 'cloud storage; (e.g. forbidden). There are tight controls on USB/DVD/Email etc, but I was wondering:
1) what the common/free cloud storage solutions are in 2019, and..
2) as a company from a policy enforcement perspective, is it as simple as blocking access to those cloud storage websites via your web filter/proxy to enforce this, or is it a bit more complicated than that. And if there is more to it, what other types of controls need to be in operation.
We have a client with a Western Digital NAS - Sentinel running Windows Storage Server 2008 R2 Essentials.
the device is retired by western digital - and we are not expecting to get much support from them.

looks to me like we need to repair/reload: Windows Storage Server 2008 R2 Essentials (see attached picture).

we are trying to load the windows dashboard - and it won't load.

anyone else manage to get through an error like this?
OCZ ARC 100 240GB hard drive.  Was in an Acer Aspire AIO running Win7 Premium 64 bit.  Put it on another computer as a secondary drive.
Took a long time to recognize the drive. It was configured as MBR.  At first in Disk Managment it showed three partitions but no data in them.  Now it says it's unallocated. Is there any way to recover Windows on this drive?

Dell H800 with suddenly 20% slower performance.  All cpu's are good, battery healthy, RAID array on MD1200 are healthy.  How do we check the write cache on the controller?  Feels like the old days when the EMC CX500 cache battery died and the cache was disabled.  

With this server, though, (running Solaris), we can't tell if the cache is enabled or not.
We have been doing some analysis of unused data on a file servers, and through doing some analysis of inventories of all files & directories on our file server drives has thrown open a number of interesting issues/challenges. Basically for confidentiality purposes each team within the organisation has a restricted directory limited to only their team members, e.g. \\fileserver\department\teamA

What we have noticed though within these individual areas are really poor structures and non-meaningful subdirectory names, e.g. individuals forenames, initials etc etc. We are trying to put a case forward or at least some all user type advice what kind of problems this type of practice cause to the organisation as a whole. Finding data could be one potentially that we could use. Can you let me know your thoughts on any risks/issues such practice poses to an organisation (if any) - I appreciate where users have the ability to create sub folders then there is almost nothing you can do to prevent them naming directories and files anything they like but even so we can at least advise on good practice.

We are a educational organisation and we have 1000 users on site. We did a server refresh 6 years before and during that time we brought 3xESX servers, NetApp FAS2220 SAN and Brocade switches with ISCSI connection.
We replaced the core switch as well and LACP was setup on these CISCO 3750 core switches by installation engineers.

Now we have come to end of the warranty on the servers and switches  and  now planning to replace the core network infrastructure .

Firstly, is the current CISCO 3750 1GbE or 10GbE

One of the IT solutions company has quoted  10GbE SAN , so will the current core switch (CISCO 3750) support 10GbE or I need to buy new core switch?

Secondly If the SAN is 10GbE do the Storage switch, Core switch  and Edge switch needs to be 10GbE? Our current edge switches are 10/100/1000mbps.

Please suggest and any help much appreciated.

Hi Experts,
I'm looking for reliable online/cloud and offline/SSD backup solution for family use. I have around 250 GB of data as of now

Reason, I had to recover my old crash portable HDD (spent $500) I had a copy of my complete files in my bad luck that crash recently as well.

Now, I'm in the process of consolidating all my files into my current latptop and backing up into my Samsung T5 SSD. I use Beyond Compare on my Window 10 Surface.

My members uses
and Mac

Thinking of something like...
1. Regularly back up (sync) to my portable SSD
2. Also Sync files online backup as well.
3. Share with my family members.

Thanks in advance
i am setting up a home lab and need a NFS server to mount NFS datastore to ESxi hosts.

Looking for an Inexpensive cloud storage for my clients backup because

any Suggestions????

Not sure if I am a complete noob or just need tips on best practices <g>

I have the sync app installed and going through setting up my o365 account.  It wants to use a really long folder name


Is it OK to shorten that?  Do I want that onedrive folder to be under c:\users\me? directly?  or shouldn't my my docs be THE onedrive folder?  I realize my docs can be inside onedrive.
Also, concerning the ability to sync the files locally - is it reliable these days? Able to deal with someone working on the cloud version while you work offline? And then it warns of changes when you get back on line? Shows differences then or you have to manually look at it?

And setting up local file sync - is that something that can be managed in the office 365 admin panel by an admin, or you have to touch the desktop / how do you keep someone from syncing too much / filling up their local hard drive?

Trying to learn and keeping in mind people that have been using local storage will have to learn this/ I need to be able to explain it to them.
A client running a Dell R620 with three disks in a RAID 5 reported amber blinking light on one of the disks though the OS (ESX) was running fine. I suggested buying a replacement which was delivered complete with hot-swap tray. The client swapped out the drive, but the Amber light continued. I thought it might be tagged as Foreign, so I scheduled a visit.  
When I rebooted the server, I went into the RAID controller to clear the (New) Foreign disk config and add it as hot spare so that it would begin rebuilding the RAID.

However, when I got in there the first disk (0) shows as MISSING, the New Disk (1) as Failed, and the third (2) as Online. I shut down and re-seated all of the drives, but no change.

The RAID is in a FAILED State, and with RAID 5 (which this is) you can’t rebuild if two disk fail or are unreachable.

I tried putting the old disk back into Slot 1, but now when I reboot both Disk 0 and 1 show as MISSING.

I also receive "There are offline or missing virtual drives with preserved cache. Please chack the cables and ensure that all drives are present." message.

I read some articles about re-tagging the Virtual Disk. Does this sound like a viable solution?

Any help would be appreciated.
