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,

I have a new 500gb NVMe SSD drive because the 250GB drive that came with the computer is not enough.
However, because there is only one NVMe slot, I cant have both drives installed at the same time and therefore I cant really use a standard drive clone to move the OS.

So I guess the best would be to make a image of the drive and than restore this image on the new drive.

Since this is a important move for me, I wanted to reach out and get some opinions on what would be the saves procedure to do a more when it is not possible to have both drives in the computer at the same time.

Any tips and shared experience would be much appreciated.

Good afternoon everyone!

I am performing mailbox migrations in a Hybrid environment!

Why am I having a problem in 3 boxes where I do not change 2013 are they? Archive while performing sync is giving the following error.

This Mailbox has 16GB, but this is being used as a mailbox or several users as members.

Migrated data:
Migration rate:
Error: MigrationPermanentException: The file size 104.8 GB (112,571,089,611 bytes) exceeds the destination quota of 100 GB (107,374,182,400 bytes). The file size 104.8 GB (112,571,089,611 bytes) exceeds the target quota 100 GB (107,374,182,400 bytes).

Hello,

I am looking fr advice on a backup strategy. Currently my environment has the following specifications:

2 x  VMWare ESXI Hypervisors connected to a SAN with 12 Virtual machines
9 TB of storage space
Physical server (end of life) that has an LTO 5 tape backup unit capable of 10+ TB of storage; It is connected to a cheap 54 TB NAS which holds all backup data
Licensed with Veeam Enterprise 9.5 (to backup VM's)
Licensed with Symantec Backup Exec (archive data to tape)

The above description for backups (and more or less disaster recovery) is in my opinion an outdated method of doing backups. I would like to move to a more modern method that meets the company goals.

I would like to do the following:

Have a retention period: 30 Days, with ongoing monthly backups
-preferably ability file level restore
-Backup to cloud or offsite data center
-Ability to restore images in Amazon (or another ESXi server) in the event of a disaster at HQ
-RPO of 24 hours
-RTO of 4 hours (if possible)

Data is safe and destination of backups needs to be a proven reliable source. Backed up data is encrypted.

I am on a tight budget.

One of the recommendations on this site was to use CloudBerry with Backblaze. I am not certain if this a good commercial solution for Disaster Recovery and backups

I still have the ability to backup everything to disk and then archive to a cloud storage vendor, although I imagine restoring data would be quite slow, even with a Gigabit …

Hi, I've never paid much attention to the D drive before because I've always had plenty of storage but this new computer offers little storage and it's not upgrateable.  So, I'm wondering, can I use some of the space in the D drive to store files, etc.? Please see pic 1. ThanksPic 1

Hello, All.

Before I go any further with the RAID 5 configuration that I currently have set up.

Question.
What is the best array to run for a web server running?
IIS, SQL Server, Mail Server, etc...

I currently have 4 - 500GB drives in the ARRAY.

My RAID card gives me these options.

JBOD,
RAID 0,
RAID 1,
RAID 10,
RAID 1E,
RAID 5,
RAID 50,
RAID 5EE,
RAID 6,
RAID 60

I have another server that will be brought into the network by the end of summer, and another server by Christmas.
So, whatever information I get here from this thread, will most likely be used across all servers.

Suggestions are greatly appreciated.

Getting Windows security prompts Win 7 Pro clients logging onto Synology NAS DS1515+ that worked until yesterday.  Domain users with admin access to the NAS are not able to login. Server is 2012 Foundation

Also getting multiple prompts when accessing the NAS via a web browser (revocation info not available, Synology certificate cannot be verified to a trusted certificate authority), integrity cannot be verified, ...) . Certificate is valid through 2036 & about 15 OKs allow the website to display.
That may or may not be related but is also recent.

Possible Windows not allowing logon with certificate issues?

I am still somewhat new to Virtualization and I am currently in the process of upgrading/expanding my VM server farm. I was going through some documents and in of the documents it mentions that I should have a separate disk array for each virtual machine on a multiple virtual machine system.

My question is what do they mean? I have a 6 disk server and would like it to host 3 VM's. From how I read the statement above I should configure server into 3 RAID 1 configurations where normally I would configure either a RAID 5 or 10 then split the array into however many disks I need for the 3 VM's.

What is the correct way? Right now I have all of my VM servers configured as RAID 5 the chop up the array into drives for the VM machines

Hello, All.

OK, I have the following.
VMWare 6.5 Update 1 (Free version)

Adaptec RAID 6805T

I have it configured for a 4 drive RAID 5.
However, it is not showing up inside of ESXi.

I found this driver.
Adaptec RAID Driver v1.2.1-52040 for VMware

However, the driver is for versions of VMware 5, 5.5, and 6.0
I have 6.5 update 1

Also, if this driver will work with 6.5 u1
How would you install it into the FREE Version of VMWare?

I also found this information as well.
I just want to make sure that this is going to work before I attempt it.
How to install 3rd Party RAID controller drivers in VMware ESXi 6.0

I would like so input on this before I attempt to do this.
As this is on a production system, and I prefer not to mess anything up.

Thanks.

I have a 128 GB PNY flash drive that I purchased for transferring and transporting files.  I was able to load a lot of files onto the drive, and work with it, but I just tried to copy files to and from the drive and all of a sudden I get a "write protected" message, and can't use the drive (the existing files on the drive appear and are accessible).  There's no hard switch for write protection on the drive, and I can't find any evidence of a software program or setting (either on or off the drive) that could account for this problem.  I tried formatting the drive, but get the same "write protected" message.  Please help.

Thanks,

Phil

Mac user.
User had an old, no longer supported Promise RAID5 that had a drive stop working.
I inserted a replacement, but after 3 days the RAID didn't rebuild.
I pulled the new drive, but even though I was able to see the folders, no files could be accessed.
I called Promise.
Because the RAID was an older model, Promise had no Promise software was able to run on any Mac to do diagnostics.  They told me to find a backup, attach the drive to a Windows Machine, and only use it with Windows.

This is a disappointment.  I had a backup on BackBlaze, but it takes days to recover 2 TB

I need to choose between:
  • Finding an old Mac that will run the old Promise software, reformatting the Pegasus RAID 5, and assuming that the error was a one-show
  • Buying a new Pegasus 2  Thunderbolt - connected unit
  • Buying a CRU RAID one, and connecting it with a Thunderbolt to Firewire 800 connector, or else USB 3

User has a collection of Videos that they want to keep on a RAID.
They do not add videos very often, and may do some simple editing from time to time.

I realize that the RAID 1 would allow them to pull a drive out for safe keeping, and then rebuild the mirror.
I am wondering if CRU unit with USB 3 connected directly to a 3 year old iMac would have the throughput necessary to play Quicktime MOV files

Thanks.

Hi, I have a Dell server RAID 5 with a PERC S110 controller.  I have two questions, can I get a walk through on replacing the failed drive?  Also do I have to use the same exact Sata drive, or can it be bigger?  The drive now is Dell MG0.ACA110.

Thanks a ton guys.

Hi,

Right now want to setup MySQL cluster and MariaDB Galeria Cluster to test the product on how well it function, so in order to prepare for it.

1. How many redhat linux nodes on testing each of this?
2. Anything else needed?
3. no shared storage is needed as actually the testing should not have shared storage and we should try horizontal scale out.
4. anything we should test on  cluster ?
5. can we use only node with 1 x network card to install ProxySQL and test it?

I own a qnap 451 4 bay system with first 3 drives populated  (2gb,3gb,3gb). The two 3gb drivers are in a basic pool and the 2gb primary drive is a jbod. I want to replace the primary drive with a 6tb drive. Is it best to put in a 6tb drive in bay 4 and have it copy some way,  or is the another way?  

What is the best way to do this without losing my config?

I just purchased a used Dell PS4000E SAN and have logged into the device and reset the grpadmin password.

I'm currently connected to the Dell PS4000E SAN with a serial to USB console cable (using HyperTerminal for Windows 10) and logged on with the grpadmin account.

Please provide me with step-by-step instructions on how I can reset this device back to its factory default settings and set it up for use within a Server 2016 and VMware environment.

I have a secondary hard-drive from a computer where the primary HDD crashed. I slave the secondary HDD to another computer, I can see it in disk management as a healthy partition, but it will not auto-assign a drive letter. I tried to manually assign a drive letter in disk management and it is greyed out (all options are greyed out).

Both PC's Windows 10 (1803) x64
Drive in question Toshiba 2TB

Thanks in advance.

Hi, I am trying to download the software for the SanDisk Wireless Stick but not having any luck.  I went to the download site and it says my drive is not connected but I have it plugged into a usb port and is blinking.  It shows up in the control panel "add a device" so I don't know how to sync this with the computer.

Also I don't understand what they mean by the ################## they show on their page.  What are they refering to?  Should I first try to connect to my router instead of the computer?  If someone is familiar with this I would appreciate your help.

Using VMware 6.7
- having problems moving VM from local storage to LUN
- tried Quick migration and vm copy

using Veeam getting errors:
1 . Processing BWSUTL01 Error: Object reference not set to an instance of an object.       00:48 (using vm copy)
2.  Processing VM GESUTL01 Error: Cannot migrate VM GESUTL01. VM virtual hardware version is incompatible with target vCenter or ESX(i).        00:18 (using quick migration)

Hoping to not have to manually copy files, if possible.

What is the process to reset the password for the grpadmin account password on a Dell PS4000E SAN when the password for the grpadmin account isn't known?

We have already tried the default password of grpadmin and this hasn't worked.

Is there any process for resetting the grpadmin account password back to the default password of grpadmin or setting it to something else when we don't have any of the logon account passwords for this device?

Hello,

I am currently  working in an environment that has not been recently updated.

The site has a P2000 SAN, an ESXi server, and a physical server (that could not be virtualized).

The Esxi server is connected to the SAN through iSCSi. The virtual machines  work well (performance has not been an issue)

The physical server is running out of hard drive space.

Does anyone know if it is possible to leverage the existing SAN and connect the physical server to it and access the storage? All the storage has been made available to the ESXi server for which there are 6 LUNs defined. One of the LUN # 6 is practically empty. Can this LUN be used by the ESXi server as well as the physcal server?

Any guidance would be greatly appreciated.

Thanks,

Mark

We have an HP ProLiant DL380p Gen8 server with 5 hard drives (see pictures of array and drives) that recently reported a bad drive (flashing on server itself and reported on system as such)
We replaced that drive and thought all is well as the event viewer warnings went away. A few days later I see event id 7, source disk, type error "The device, \Device\Harddisk0\DR0, has a bad block" but the array does not report any drive issues. How do I figure out which drive it is since the Harddisk0\DR0 basically references the entire c: and d: drive on the system when I look at it through storage manager. I also see event id 24606, source cissesrv, type error

Logical drive 1 of array controller P420i [Embedded] returned a fatal error during a read/write request from/to the volume.  
 Logical block address 66027424, block count 32 and command 32 were taken from the failed logical I/O request.  
 Array controller P420i [Embedded] is also reporting that the last physical drive to report a fatal error condition (associated with this logical request), is located  in bay 4 of box 2 connected to port 1I.

the previous drive with issues was reported as
 Array controller P420i [Embedded] is also reporting that the last physical drive to report a fatal error condition (associated with this logical request), is located  in bay 1 of box 2 connected to port 1I.

So does that mean we have another drive with issues, but it has just not failed or started flashing yet?arrayphysicalview.jpgarraylogicalview.jpg

I'm looking at purchasing a server to run hyper-v, originally i was going to go with 8 x 900Gb 15Kpm SAS drives in raid 10. then my boss mentioned about some more projects, meaning I have now needed to look at more space. I'm now looking at 10 x 1.2Tb 10Kpm SAS drives in raid 10.

due to the 1.2tb 10k being about the same price as a 900gb 15k, I'm stuck in a dilemma over space and speed.

so i looked up a raid calculator

8 x 900Gb RAID 10 will give me 3.6Tb with speed gain 8 x read and 4 x write - but note they run at 15k speed drives

10 x 1.2Tb RAID 10 will give me 6Tb with speed gain 10 x read and 5 x write - but note they run at 10k speed drives

does the rpm of the drive matter when you can see an increase in the bandwidth of the drives ?
