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 need to migrate about 60 VMs on 15TB of storage from one vCenter cluster to a new one. Both clusters will be on the same management / VM subnet (10.0.0.0/16 - latency < 1ms) - basically, we are just upgrading / replacing the hardware within the same physical datacenter because it is nearly five years old.

The old vCenter cluster consists of three hosts and a 3PAR SAN (7200). It is running vSphere 5.5 Standard.

The new vCenter cluster also will consist of three hosts and has a Nimble SAN (CS3000). It will run vSphere 6.5 (probably Enterprise Plus).

On each cluster, the SAN network (FC) is local to the cluster itself - so, one cluster cannot "see" the other cluster's SAN (each cluster has its own FC switches). The vMotion VMkernel network on the old cluster (192.168.100.0/24), however, could be made visible on the new cluster via vLAN (i.e. the new cluster could use that same subnet for its vMotion VMkernel, with three unique 192.168.100.x addresses).

What would be the easiest and best way to migrate VMs from the old cluster to the new? Ideally, we'd like to be able to storage-vmotion from the old to the new, but doubt that that would be possible (as the two clusters would not be able to see each others datastores - would they?)...

I've taken over a configuration of BareOS on Debian GNU/Linux 8 (jessie). Its a fresh install, using both file and Autochanger storage.

Everything looks correct and bconsole will talk with the changer (I can move, mount, unmout, label tapes etc.).

Problem: The backups will write to the autochanger's drive - but ONLY if the tape is manually mounted. If the drive is empty, the backup job will not pull a tape into the drive. It just stays queued indefinitely. If I move the tape to the dirve (even after the job is started) it runs fine.

The tapes are barcoded and labeled.

See pertinent config below:

Hi

We deployed an IBM System X 3550 Server some years ago.  The server has 3 SAS disks in a RAID 5.  One of the disks has now failed so I began the process of finding a replacement drive.  I intend to buy 2 so as to have one as a spare. The Disk I need is A System X 300GB 10k rpm 2.5" SAS Part No 42D0637.
HOWEVER!  The distributor just informed me the the cost of each disk will be €413.00 plus VAT@23% plus Delivery - circa €500each!.

Can any Server hardware specialists tell me if I need to replace the disk with the original or is there any alternative?
Now I need this server as it runs some critical applications so I need to act quickly.  Thank you

I have a QNAP Turbo NAS TS-459, Firmware version 3.8.3 Build 20130426. Up to now it has been part of a Windows 2003 domain. However the domain controller has gone west and in Administration/Network Services/Microsoft Networking I'm trying to set it to a standalone server. The option is currently greyed out. I thought that if I disabled "file service for Microsoft networking" I could start over but every time I take the check mark out and hit "APPLY" the check mark reappears. Can anyone help?

I am using Microsoft SQL Management Studio 2008 which is connecting to a SQL database of course.
There a backup that runs and puts *.bak files into a backup folder for storage.  I have the following questions.

1. Is it Ok to go into the SQL \ backup folder and manually delete the backup file - *.back ??
             Will this manual delete hurt the database. ?

2. Is there another way of deleting SQL backup files. ??

Hello,

I was testing a GDisk DVD for a client and it started to wipe out my laptop.  The partitions are still there, but unaccessible.  When I try to access them I receive the message:

The volume does not contain a recognized file system.

Please advise.

Thank you,

Hello, I want to buy a new Win2012 backup server that around 20 servers will backup system images and folders to this on daily scheduled tasks, and also a few times a day via DPM.

It will need approximately the following HDD capacity.
- 5TB to be set as a DPM target
- 5TB to just used for files/folders backup target

I will need to RAID 5/6 the disks, do I need 2 distinct RAID arrays, one for DPM, and the other for files?
Is DPM processor/RAM intensive, what do you see as reasonable processor and RAM options?

Thanks

A friend has a Dell Inspiron 11 3162 that was acting up & once I got past the dog-chewed power cable, I found there's basically no disk space left on it! It appears that the HD is soldered to the mobo, so no upgrade options there. Looking at it with Treesize, the biggest space hogs are the WinSxS directory (4.2GB) & Origin Games (8.3GB). It has a couple of USB ports & a MicroSD & I planned on getting a 32 or 64 GB card or USB drive & set game preferences to use that for storage or would I need to re-install games to that location? Other than eating up one off the 2 available USB ports, any advantage to SD card vs USB drive?

We currently have a server that has two 450GB drives in raid 1 and we are constantly facing space issues on this server. We are wondering if we replace one of the drives with a new 900GB drive, let it rebuilt, then replace the other 450GB drive with another 900GB and let it rebuild. Can we then extend the volume in the raid controller and then again in the OS to increase the space?

This is a physical server, so we can't just add more space like a VM. It would also be a last resort to rebuild the server on larger drives, which is why we are looking at the above solution.

Does anyone have experience with this, or know if it will work?

Hello Experts,
after Power failure my private ARM cubietruck's linux installation was broken. I have the suspicion that squid3 cache_dir has broken the filesystem. All most important files are "restorable" unfortunately without some squid3-Files.

Optional I can use different store types for cache_dir cache_dir and I wonder if there's a way to use external storage (NFS, SSHFS etc.) for it (within a mount) .

Three Reasons Why Backup is Strategic

Three Reasons Why Backup is Strategic

Backup is strategic to your business because your data is strategic to your business. Without backup, your business will fail. This white paper explains why it is vital for you to design and immediately execute a backup strategy to protect 100 percent of your data.

A file server will be converted to a virtual server hosted by VMware.

1. Should I convert data partition (which has 4TB) or data , or
2. Atach a NAS on the orignal server and copy the folders into the NAS. Convert C partition to a virtual server. Afterwards, create a virtual data partition and copy all folders to the virtual server


Which way is faster ?

Thx

i have a disk in a virtual server that is 1.27 TB. I need to increase it. i went in and increased the size but when i go to server manager, file ans storage services, volumes, disks,i try to increase it but it still says max size 1.27 TB but 75 Gb free. How can I increase the space? it is a GPT partition.

Dear Sir,

I had an iPhone with ios version 10.3.3. Recently, my iPhone is out of space. I have checked my storage information. It shows my notes app used around 800Mb. I connect my iPhone with the PC software iExplorer and I found that the deleted notes are over 100+. I understand there's mechanism the phone will not delete the notes which within 30 days. But why the iExplorer still showing the notes still there. How to remove those "deleted" notes permanently.

Please advise.

Thank you.
with regards,

The entire rundown of my issue can be found here ( https://h30434.www3.hp.com/t5/Business-PCs-Workstations-and-Point-of-Sale-Systems/z420-Raid-config-and-more-than-HDs-plugged-in-issues/m-p/6305402/highlight/false#M18295 ) but I'll hit the high points here-

  • HP z420 Desktop
  • Windows 10
  • 2x 128 GB SSDs
  • 2x 1 TG normal SATA drives
  • All HDs have been scanned, no bad sectors
  • All HDs have been formatted NTFS
  • The machine was set run in RAID then I changed my mind and broke the RAID
  • The BIOS on the machine was reset to factory defaults
  • The BIOS was updated to the current version
  • I cannot get more than 2 HDs to get recognized by the OS at any time
  • Those HDs must be in the first 2 SATA slots
  • When all 4 drives are plugged in, the 2 HDs recognized show up in the BIOS.
  • The 2 HDs that aren't recognized show up in Intel Storage Manager

Any help is appreciated.

I have a Dell T410 server with a Raid controller and 4 x 146Gb HDD in a RAID 5 array. This only gives me 438Gb usable space.
I have two spare slots in the server. Which option would be best?
1) Add another couple of discs and have a RAID 5 array of 6 discs?
2) Add a disc outside the RAID configuration
3) Upgrade all 4 discs to larger capacity, say 4 x 1TB
4) Any other option I've not considered

This is a live machine so downtime is limited and I'd like to keep the risks as low as possible. It's near its end of life (SBS2008) so I just need to keep it running for a bit longer

People,

I'm running on 3PAR Array for all of my Tier-1 production VMs (SSD - 10 GB ethernet iSCSI), So I wonder if I need to isntall any .VIB or HPE ESXi VMware .SIO image to utilize the best practice in the 3PAR multipathing ?

As at the moment I can only set it into Round Robin (VMware) as opposed to the current setting Fixed (VMware) .

I work in an education environment, and need a new VMware server that will support up to 100 VMs.
Each VM needs to be able to perform a minimum of cpu-intensive activity.  Basically, I'm asking for "minimum reasonable requirements" for a server with 100 VMs.

I have compiled a little document concluding that I need 32 physical cores, 300 GB of RAM, and 8 TB of storage.  It's based on a document I found from VMware, "VMware Server and Storage Sizing Guide", at https://www.vmware.com/content/dam/digitalmarketing/vmware/en/pdf/technicalnote/view/server-storage-sizing-guide-windows-7-technical-note.pdf 

Feedback?  

(I'm familiar with VMware, but I'm not an expert.  This will be the first VMware server I've purchased.)

The next request will be suggestions for vendors, i.e. what will this cost me.

Thanks so much.

Hi,
let's suppose I need to recover server from a customer, which is unable to tell me technical configuration details.
Server has 2 disks, I guess there is RAID 1 configuration, but I am not sure.
In particular, it seems that CMOS battery memory was cleared, so I can't assume if there is a RAID 1 volume assembled by raid controller, or if software raid (OS level) was used.
How can I determine this?
Thank you

How Blockchain Is Impacting Every Industry

Blockchain expert Alex Tapscott talks to Acronis VP Frank Jablonski about this revolutionary technology and how it's making inroads into other industries and facets of everyday life.

Hi,

Recently decided to build a custom PC to test and use for Fiber Storage.  I'm going to be using Solaris 11.3 as the main OS (If I need to go back a version that's fine too).  I'm having issues getting the OS to install.  I'm thinking it might be a setting in the BIOs that is effecting the install and/or CPU model.  I will list all the components that I have in the custom build and what is actually connected to rule out compatibility issues.  I will also list what I've already gone through.  I'm not a Solaris, Linux, Red Hat person so if you suggest to edit a config or change something I'll need detailed instructions on how to go about it if possible.  But I'm pretty sure I've almost narrowed it down to something in the motherboard in the BIOs or the CPU that is effecting the boot process.

What Happens:

- I've tried the following: Burnt a DVD with Solaris 11.3 Live ISO, Burnt a DVD with Solaris 11.3 Text ISO, Formatted a USB Stick to Boot Solaris 11.3 from the .USB file

When booting from any of these options listed above the initial booting of the OS freezes at a certain point.  When booting from the Live ISO, after selecting what you want to boot (in this case Solaris 11.3), it will change to a black screen with 2 lines of white text and a cursor and then freezes.  Before selecting Solaris 11.3 to boot, you can hit the "E" key to edit the boot file and this is where I've added a " -v " on one of the lines to see more output of where it freezes.  When …

Hi  all,
I have a general question about software vs hardware iscsi initiator, hope someone will explain.
We are using software iscsi initiator,  multiple nic ports and each is configured with in a separate subnet.
As far as ESXi concern, it has multiple paths at ESXi side. When I looked at EMC VNX's hosts' info and it warns that there is only one HBA from a host and you have " HAVT issues."
Does this mean that software iscsi initiator is treated as HBA? Is anyone using iscsi with VNX?

Hello all,

My 1 TB Dropbox PLUS subscription is coming up for renewal and I am seeking a less expensive cloud storage service.

I should say that my only two issues with Dropbox are:
- Price - especially since I wish to upgrade to 2 TB of storage.
- That I must use Boxifier (3rd party add-on) to sync multiple folders from multiple locations.

I especially love Dropbox because:
- It's excellent web interface.
- Version control (I can instantly recover a file or files from any time within 30 days).  

Recommendations Found

From https://www.cloudwards.net/comparison/, I found the following alternatives:


All appear to offer the features that are most important to me. Any other recommendations and/or endorsements for the above three choices?

Thanks,
Shawn

Hi,
I need to access file system on this very old server (Windows 2003 server R2).
There is embedded Sata RAID controller.
It seems both disks are reported as "smart failed"..
What chances I have to access data?
Thank you

Dear people,

I hope you are doing well. I am implementing for first time VMware and Dell Storage. Actually I dont have experience with them.

Devices:
2x Dell R730 server with VMware images on SD cards
2x Dell N1548 switches
1x Dell EMC SCv2000

What did I do?
 - connected servers and storage over switches
 - configured NICs and iSCSI
- Created Fault domains 1 and 2
 
Fault Domain 1 and 2 are  reachable. But when I click on Next I got error: Unable to retrieve data from VMWare. Please try again later.

If some have procedure how to do it, please send me.

thank you
