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,

I have a failover cluster with two DB servers.

They are connected to a Lenovo V3700 V2 SFF SAN Storage.

How do I configure the Quorum, when I tried to add the disk witness, it does not show the volumes I created from the SAN

Create a reliable backup. Make sure you always have dependable copies of your data so you can restore your entire system or individual files.

Dear Experts,

I have setup the pools, added the storage, configured the volumes and mapped them to the host.

On the two 2012 r2 servers that are connected to the SANs, they are able to see the 4 volumes created.

But the SAN is showing that both fiber ports status of the two servers connecting to the SANs are degraded.
We have a raid 5 cofiguration, and running out of space.  It is on a dell server r620 with perc h710 mini (embeded) controller.  If I were to replace one hard drive at a time to bigger size and let it rebuild .. will I be able to increase the size of the volume on the raid without having to backup and restore?

I have read contradictory information and I want to make sure, for example below is a link that gives step by step on how to achieve this.


I have an HP DL380p Gen8 server that has 2 Smary Array 420 controllers. Because of space issues I needed to move a pair of drives that were in a RAID1 set from slots 7 & 8 on the left side which was controlled by the 1st RAID card to slots 7 & 8 on the other drive cage that is controlled by the 2nd RAID card. However, after the drives were moved they showed as unassigned so, I shutdown the server moved the drives back to there original location of slots 7 & 8 which is on the 1st Array card now they are showing as unassigned there as well. Is there a way to recover the RAID set on those drives or is the RAID configuration gone?
I got a DS415 synology nas.
got an external harddisk(1TB) plugged in to it.
so using hyper backup to backup files from nas to external harddisk.

currently, backup fails- because no space in destination.
i have posted the pic of current config of the rotation policy. can someone pleas have a look at it, and let me know what needs to be changed, so it deletes the oldest backup automatically and creates space for new backups in future.

any help would be great.
We have a file server cluster in one of the sites running on windows 2012 R2. We will be migrating the file server to windows 2016.
We had an incident earlier that the hosting infrastructure that runs all the virtual servers went down. Now the company wants this to be considered and make a solution that in case such incident happens in the future, the users should still be able to access the files from the second site.
We have two sites with good bandwidth. I am thinking of using the new feature in window s 2016 DC i.e the storage replicas. We want an automated switchover if in case infrastructure in any of the sites has an issue, it should be accessible from the other site.
We have file server cluster in both sites. Either one of them goes down it should AUTOMATICALLY fail over to the other site.
So a customer accidentally formatted a 2TB hard drive to NTFS. I used the usual techniques to try a recovery but nothing worked (Testdisk, Ontrack).
After discussing with him it looks like the drive was previously HFS.

I was wondering if this new information can help me? I never tried a recovery from HFS but I don't think it should be very different with Testdisk.
Dear all,

Good evening.

We have received a Dell R330 and a Dell MD1400 and we need to configure the storage system, and create an NFS file system exported through the R330.
Does anyone has performed similar configuration of the storage? Any technical references available?

Any help would be appreciated.


What is the best RAID with 8 hard drives SAS 600GB, 15k tr/min 6GB/s (HP 517354-001) for virtualization server (VMware ESXi 6.5) ?
Basically we have multiple applications (MS Active Directory, Terminal Server, Oracle, basic file server,...) , one with intensive Oracle Database operations
There's two others array RAID5 SSD total 1TB and RAID1 300GB
Thank you.

Best Regards.
We have been getting these errors on Physical Disk 4 on our first virtual host:

There was an unrecoverable disk media error during the rebuild or recovery operation: Physical Disk 1:0:4 Controller 0, Connector 1

I did what it said to in the comments which was to swap it out with a new disk. However, after doing this and letting it rebuild, the same error repeats over and over again.

What can I do to stop this? All the lights show as green on the OpenManage console and in the rack itself.

I need help for merging 2 switches where VF needs to be disabled.

Below is our current Brocade switches configuration;

Model: Brocade 6520



VF > Enabled

1) FID: 128
> cfgzone: Not Defined
> Fabric: n/a

2) FID: 2
> cfgczone: Zoning_A (Defined and Active)
> Fabric: Switch_1
3) FID: 6
> cfgzone: Zoning_B (Defined and Active)
> Fabric: Switch_1 & Switch_2

All FIDs, i.e. 128, 2, 6 have ports connected and zoned.

Scenerio 1: Disable Virtual Fabric

(A) We need to get rid of virtual fabric, i.e. FID 2, 6, and finally 128
(B) I need Default switch into Fabric with no impact to current zones and alias.

> I am ok with Downtime of assets connected
> I am ok with creating a New Defined Zoning Configuration.

Scenerio 2: Keep Virtual Fabric Enabled, but delete FID 2 & FID 6, so using just Default FID 128

> I am ok with Downtime of assets connected
> I am ok with creating a New Defined Zoning Configuration.

> What will happen to zones and alias when ports are move from FID 2 & FID 6 to FID 128
> What will happen to zones and alias when finally all ports are in FID 128 and we disable Virtual fabric

Step by step process to achieve scenerio 1& 2 will be highly appreicated.

How to transfer the Domain Based DFS from one server to another server on the same domain. The share drives are on the NETAPP storage.

Digital transformation is a challenge for data center infrastructure. RCCs need to be able to adapt to massive data growth and handle new workloads. It is a mammoth task for data center managers to meet all these requirements.

In this IT environment, companies need:

- adapt quickly and skillfully to changing requirements.

- simplify the management of complex distributed infrastructures.

- increase the use of infrastructure to reduce Opex and Capex.

- provide more flexibility through interoperability and open standards.

- IT managers need a new data center architecture that enables them to quickly respond to growing and changing workload demands, quickly reusing unused resources, and managing even more IT infrastructure with existing IT staff. This is where Rack Scale Design (RSD) comes into play.

What do rack scale design solutions offer?

Providers of RSD solutions enable a flexible IT architecture with their applications. It helps cloud service providers, enterprises and communications service providers transform their data centers by disaggregating servers into compute, data storage, acceleration and network resource pools, which can then be dynamically aggregated into load-optimized systems. With such RSD applications, users can create nodes in seconds to run bare-metal stacks, virtual machines, or containers-all from a single management console. This simplifies data center management and at the same time increases the sensible use of resources. In addition, open standards ensure interoperability between the various manufacturers.

Interconnecting systems on-the-fly saves data center managers from the time-consuming task of manually reconfiguring hardware. Nodes are optimally configured for every workload. As workloads change and resources are underutilized, they can easily be reassigned. For example, data center managers no longer need to plan for overcapacity for certain workloads because new resources can be added at any time.

Many RSD solutions are based on the state-of-the-art, open REST compliant Redfish API standard, which is becoming increasingly popular in the industry. By applying an open standard, they free end users from a "lock-in" and provide a proprietary solution. For example, OEMs can focus on innovation and differentiation away from general basic capabilities, thanks to the use of their vendors' open source reference software.

 In the future, the system will gradually allow all compute, data storage, and I / O resources to be pooled. It provides an easy path to an open, all-encompassing software-based infrastructure.

Compilation of data center partitions

QCT (Quanta Cloud Technology) has been an important partner of Intel for years and one of the first companies to use its RSD application for its server racks to drive the construction of advanced data centers and cloud environments. Such single-console RSD solutions provide scalability, efficiency, flexibility and optimal management. As a rule, the respective hardware comprises the controls of an entire rack. What's needed is management software that then manages servers, storage, and network hardware in the rack.

There is management software that incorporates the latest RSD software components and enables composite nodes to work seamlessly with each hypervisor. Users can group compute, network, and datastore resources into custom physical nodes called pods. For example, the QCT Rackgo R solution generates a complete, end-to-end view of all users' pods to monitor multiple workloads and multi-tenancy use cases. Pods can be configured to support a wide range of different workloads within the same data center and optimize resource utilization during load changes. With certain hardware, it is possible to disconnect parts from the rack and replace them while keeping the rest of the servers running unchanged.

Illustration of the network topology

Network diagrams are crucial in understanding how the network topology is tied to business. In addition, they provide an overview of what happens in a network. Typically, IT solutions automatically discover devices in a data center, create an accurate network map, and update them as new devices are added or removed. This saves a lot of time compared to manual updates, as organizations can use a simple management graphics interface to pinpoint in time where infrastructure shortcomings exist and which components need to be upgraded or replaced.

Database Migration from HP Storage to DELL EMC:
After renaming of SQL Server 2008 R2 Default instance, We are unable to connect Management Studio from remotely for Windows Authentication users. It is working fine for SQL Server Authentication users.

Error: The target principal name is incorrect. Cannot generate SSPI context.

Meantime for SQL Server 2014 it is working fine.

Scenario 1:
Server : SQLCL (SQL Server 2008 R2) - We have build new server with the name as SQL2 then migrated the databases, added alias name as SQLCL. In this scenario, we faced same mentioned above error.
Server:  DBCL (SQL Server 2014): We have build new server with the name as SQL1 then migrated the databases, added alias name as DBCL. In this scenario, we have no issues.

Scenario 2:
Again We have renamed the server from SQL2 to SQLCL and SQL1 to DBCL but Still we are getting same error for SQL Server 2008 R2 version installed.

But we have no issues jobs and every thing fine. Please help us.

I need to help someone get a laptop. The ones I am looking at have a small SSD and a much larger HDD. How can I configure the system so the user isn’t filling up the SSD with data or programs?  Is there anyway to force everything except the OS to go to the HDD with little or no user interaction?
MSA 2040 SAN + HBA card+Windows 2012 R2 Server. Drives do not appear in Disk Management. The SAN Storage is connected directly to server port A1 and B1 to HBA card, SFP+ all active, I can see initiators but when i create drives they do not appear on the server. Might be missing something here.
I believe I am having some performance issues with SOFS that is running on our domain.

We are using Windows 2016, but we aren't using SOFS Direct.

Our setup has 2 hosts, Storage1 and Storage2. Each machine has 3 networks.  Domain, Cluster and Storage that are used for what they are named after.

Each Host is connected to all 3 JBOD's twice with MPIO installed on both machines.

Virtual machines are running without much of an issue, however I am trying to diagnose another problem with DFSR and I think it is to do with the speed of the storage.

Each JBOD has 16 1GB HDD's and 5 SSDs (one has 6)  The virtual disk has a column count of 8 and a data copy of 2

When I first set this up I was getting great speeds using the command diskspd.exe -b64K -d10 -h -L -o32 -w30 -t2 -c2G io1.dat io2.dat io3.dat io4.dat io5.dat

I have been running a Dell Precision 7600 for about 5 years for a small business. Recently, I had started to have some strange problems with Win7. Thought it might be HD failures (SAS), so did checkdsk and that crashed. Had PERC H710p, removed one of the HDs (storage), not boot, and was able to start up windows fine. Then replaced that HD, removed other storage HD, and all of a sudden PC can't find any of the HDs on startup.
Just bought a new PERC H710p in case that is the issue.
I'm looking for an independent consultant genius (not DELL tech support!) who can advise me/walk me through PERC setup, in particular at least I want to be able to copy data off of my old SAS drives.
Any advice?

Does anyone know If its possible to add disks to a HP D3700 disk enclosure while its online and active?

This article details my method on how to store a virtual drive on cloud storage, such as Dropbox, without having synchronisation and indexing issues.
I am trying to reset the IP address and the superuser password to defaults for a V3700 IBM Storewize using satask commands but to no success. No one knows any of the storage IP addresses at the moment. Hence the need to reset them to default.

 I do not have the initialization tool that is normally shipped with the storage in a USB drive. I cannot download the tool either because it seems it requires the storewise to be associated with some warranty or IBM hardware support contract for the download to continue. Anyone who has the initialization tool, you are welcome to share it with me. Otherwise i would like some advising on the use of the satask commands, especially their syntax.
i had a nas storage unit and the mother board on the unit died.

i wwas wondering if i purchase another nas storage without the drives will the new unit accept the drives and will ii be able to have access to the data on the drives.

in simple will the new box identify the raid5 and allow me to copy the data off
I have an HP Gen 9 server with 8 1.2T 10k sas disk (Local) and VMware installed on internal SD card, all disks are currently in RAID 10.
We're having an issues with our SQL server preformance and from what I've read and understand we need to separate the locations of the DB files from the log files, the problem is that even if I'll create a new drive it will still be on the same disk array so it's the same as putting them on the same drive.
My question is this :
Should I break the RAID and create new RAID 10 based on 4 drive each and then put the DB file with the OS on Data store 1 and create a new drive for logs / tempDB and put it on Data store 2 ?
Or do you have any other suggestions?
I can't replace the drive s to SSD because of the price is too high at the moment.
Any help will be appreciated.

Thanks in advance
