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.

Dear Experts, we purchased Disk enclosure HPE 2050 yesterday to expand the storage capacity of SAN storage controller HPE MSA 2040.

We connected 1 SAS cable from OUT port of 2040 to IN port of 2050. After that, we turned on the 2050 device and add disk group, built RAID6 but it seems like take longer time than expected. Moreover, we got the "Degraded" status on Disks information, so is it normal? Can you suggest please? Should we connect the other SAS cable between 2 devices?

Hello and Good Evening Everyone,

            My fiancee wishes to back up her pictures stored on an iPhone 5s to a new Alcatel idealEXTRA Android Version 8.1.0 which brings me to this upcoming question of interest.  Is it possible to hook up a small USB storage device about the size of a flash drive to the iPhone 5s, back up the pictures to it, disconnect it, plug it into the Alcatel idealEXTRA and transfer or copy the pics to it?  If there is such an external storage device for backing up and transferring pictures between phones, could someone provide an online purchase link?

             Thank you

EMC Unity550F, Is it safe to perform a conversion of a LUN from Thin to Thick using the Move request in the EMC Unity550F?  These are VMware VMFS Luns that have VM's on them.  

I was thinking I should first Storage Vmotion them off this lun before I do the conversion.  But I wanted to check here if someone can confirm it is safe to do the conversion while there are VM's on the LUN.

Please can anyone confirm?

Customer called, they are having an issue after a Synology DS1515+ system had a power failure.
The customer moved the drives to the new Synology NAS.
Once they did this they powered up and had to check consistency.
The consistency scan ran for 5 or 6 hours. From there when that ended, we could see the iSCSI information on the Synology.

We went into the ESXi console, Tried adding a storage adapter and connection that would target the NAS and see the datastores.

When we add the host name of the iSCSI target, we don't see anything populate. But if we go in and add the IP address of the Synology in question under the Dynamic Discovery, we see 3 disks come up under static. It shows the .25 IP address and an IPv6 address for each of the LUNS.   But even with the LUNS showing up in the discovery area, we still can't target the storage and see it under the Storage Adapter as noted in the image attached. How can I get the Synology NAS to show the iSCSI Target so the system will boot again?
Outlook 2013 receives error when trying to send/Receive. " 
Task reported error (0x8004060C) : 'The message store has reached its maximum size. To reduce the amount of data in this message store, select some items that you no longer need, and permanently (SHIFT + DEL) delete them."

I have 5 users that use this mailbox, (HR). Four of them are using Win 7 prof and the other is using win 10. They receive this error whenever they try to update the mailbox through outlook. "Send/Receive Tab" Using O365 (E3) subscription 100gbs of storage,  they can access the account through web access and report no issues from using web access. Only when using the Outlook App.

Steps I've already taken.
1. Archive
2. Adding reg keys to increase size.
3. Blew up the entire user profile and User account. Rebuilt mailbox.
4. Split up and compacted outlook data files.
5. Deleted as many emails as possible.

Any assistance would be greatly appreciated.

Thank you
I have Proliant DL360 Gen 9 with Smart Array P440ar.  I installed a 4th 300gb hard drive into an existing Raid 5 array.  I don't know how or why but my array switched to Raid 6 (ADG).  At least i think it did because I believe I originally set it with Raid 5. My question is can i downgrade it back to Raid 5 without losing data in the array??
Storagepools vs Raid 10.
Hi. We are setting up a physical server (not running Hyper-V) to act as a Domain controller and a SQL server.
Plan is to use 8 x 600GB drives (SAS) sat up in Raid 10 (using onboard Raid controller - HP ML 350 Gen10 server)
Divide in 2 partitions C: for Win 2016 and D: for SQL data.

Not familiar with storagepools.
Is an option to use 2 disks in a mirror (created on raid controller and create a Storage Pool in File manager after windows is installed.
Looking for max r\w but also safety in case of disks crashing.

This setup may also be used for single Hyper-V host as well?

Happy for any suggestions
I need to add more space to one of our new customers pre existing server.
Its really a regular pc that is running server software.

the mainboard is a Gigabyte z77x-ud5h. i7-2600k processor.

right now they have 2 256 GB SSD. and they have them setup for raid 1 using intel rapid storage technology version

We need to add more space but I am not familiar with this kind of raid. I'm used to HP ProLiant servers and dell. that have their own software.

We are going to put in 2 500 GB DHH to make more space but I'm not sure how if this software support 2 separate arrays.
that way I don't have to reinstall the OS>

When I go into intel RST  there is no option to add anything. I don't have the new drives hooked up yet. I was just checking where to add or if you can add more than one array.

I found many solutions like solar wind, Zetta , MozyPro, CrashPlan...etc. My data size almost 2T. I really need help with this. Can you help me or suggest good backup solution with affordable price?

where I can use the lto ,,, ? for archiving or data backup ?
In a Dell T430, we are going to replace the existing PERC H330 RAID controller with a PERC H730 RAID controller.   We have been advised that "all we need to do" is remove the existing controller, install the new one, and "import the configuration."

Can we use Dell's OpenManage softwaere to export the configuration (i.e. to a flash drive), then after installing the new controller, import the configuration?

Suggestions on how to proceed?

Thank you...
I have a dell PowerEdge R610 physical server (W/Perc H700 Raid Controller) that is setup as an esxi 6.0 host. The 3 internal disks are setup in raid 0 for some reason and i want to know if i could swap the prefailed drive with a new one (which i already know will kill the raid 0 array configuration) will i be able to rebuild the raid array to be raid 1 with Dell EMC OpenManage Server Administrator (OMSA) without shutting down server? The hard drives are not dell certified disks.
Dear Experts,

This server has two HDDs of 300GB each and a smart array controller P410i installed with VMware which our customer give to us.

The issue now is we want to clear the data from the 2x HDDs.

1. I have tried going into the array configuration page and change and remove the RAID.
2. Boot using Windows 20121 R2 DVD installer
3. Removed both HDDs and power on server
4. Used a USB thumb drive as an installer
5. Connect a USB DVD drive to run WIndows 2012 R2 installer
6. I am unable to use iLO2 as the virtual media license is required

All the above I tried and it does not work, the server just boots and goes back and run VMware.

I have ran out of ideas.
I have an old Dell PE2950 server with Perc 6 hardware raid controller in place. I'm setting it up as a storage for backup location. I would like to install 2012R2 on it and use Storage Space. But my question is, do I need to use or configure hardware RAID if I want to use Storage Space? I understand Storage Space does provide RAID feature already.  Appreciate if you can give me some suggestions. Thanks.
i have a VCenter 6.7U1 with a cluster. The attached storage is Freenas ZFS volume. I also have another attached storage Dell Equalogic. I attempted to use the migrate function VMotion to move only the storage from a VM from Freenas to the Dell Equalogic. It performed successfully but when i went back to the Freenas, the VM was still sitting there.

So, the VM was in two storage containers, Freenas and Dell Equalogic. Its almost as if VMotion did a copy instead of a move. The VM did not have any snapshots either.

Anyone can help with this?

We use Git to manage all of our code for our client’s projects etc.

I’m looking for a solution that will do the following:

01 - backup Git (just in case)

02 - auto backup databases for each client’s project to the same backup service

Thanks in advance for your help.

Can I use a 172.47.x.x range IP to communicate point to point with an EMC device and a storage server network adapter?

If I add static routes for both they should work right? Despite the 172.47 being a public ip range
Hey guys,

I’ve two PowerConnect 6224 switches which are linked to a Dell SAN (for redundancy) and one of the switches are then plugged into the local LAN.  I’m changing the local LAN switch but when I connect the Power Connect SAN switch to the new one, it doesn’t work - I can’t access any of the servers on the SAN - it’s a big odd, as there’s no config on the previous LAN Switch- what am I missing?

Greetings EE'ers,

I am looking for a good solution for file management and  data storage options for a small Law Office.  There are several "canned" solutions out there that are mostly hosted solutions, which is fine, but they all seem to be pretty expensive.  Does anyone know of any good solutions for this?  Either on prem storage or cloud solution is ok...or even a combination of both, as long as it's compliant for legal documents security requirements.

I am having problems moving a virtual drive from one storage location to another on one of my VM Machines but can't understand why. The VM I am trying to move the drive on is our Production SQL server that serves up data for our ERP system. The data and all drives currently sits on a SAN we purchased but the 10K drives cannot handle the requests so I thought I could move that drive that contains the SQL database to a HOST that has a bank of SSD drives. That datastore is 735GB and the drive I want to move is 400GB so it should fit however when I go to Migrate the drive it says that there is not enough room. What am I doing wrong? Can I move a drive off a SAN to a local Datastore on a host? Do I need to move the whole VM drive structure to a new datastore? I was under the impression I could move just one drive which it looks like can be done but I don't completely understand the process.

When I am in the advanced settings of the migration process do I need to tell the application where all the drives need to stay and where to move? I mean In the Advanced window do I need to tell the system to keep all the drives on the current datastore (SAN) and change the one drive to the new location? I was just telling it to move just the drive but each time I would click next it would tell me that there isn't enough space.
options to use when Disk Consolidation does not work

I have reading about the options that might resolved  Disk Consolidation issues and some of them are here:

1 - Create a new snapshot and remove it, this might complete the consolidation

2 - vMotion the VM to another host and try to consolidate again

3 - Restart the management agents on the host where the VM is running and try to consolidate again

4 - Restart the Backup Services (one of the backup  services might be locking the snapshot files, preventing them from consolidating)

5- Shutdown the VM, try to consolidate again

Regarding Option 3, I would like to know what would be the impact when your restart the management agents on the host. will this migrate the VMs to another host with no issue ?

if you have other options that can fix Disk Consolidation issue, please provide the options.

Thank you
