RAID 10 Setup Using HP P4000 & P4500 SANs

At Nottingham Data Recovery our engineers are well versed in dealing with the recovery of data from drives that have failed within RAID 0, RAID 1, RAID 1+0 and RAID 5. These setups are universally accepted by a great number of institutions as the way in which to save their data and to make it accessible to their staff and for the most part they work fine.

We also deal with clients who use RAID 10 setup, a more intricate and detailed system by which the data is mirrored and striped across more than one storage system. This is common with users of the HP P4000 and P4500 Left-Hand SANs (Storage Area Networks) which allow for the coming together of two or more storage ‘nodes’ in a cluster.

It all sounds very complicated by the reality is that using RAID 10 is no more difficult that using smaller RAID setups over a larger area; for example having two setups on site in different locations.

When it comes to accessing high volumes of data on a frequent basis across a network used by a large number of users it is generally accepted that RAID 10 is the best way to go and this is no more apparent than when using setups such as the HP P4000 or P4500 SANs (Storage Area Networks). Allowing for the use of RAID 10 allows for more than one of these devices to work in conjunction with each other and allows for a greater level of flexibility when it comes to accessing and writing to data already stored across them.

Multiple users can access data in a matter of seconds across an IP and Ethernet network that allows for high levels of data transfer anything from 1GbE to 10GbE whilst making full use of the iSCSI setup and generally the HP StoreVirtual Centralized Control Management Console.

RAID 10 or Network RAID also allows for use across multiple sites where other RAID setups such as RAID 0, 1 and 1+0 do not. In the event of any kind of hardware failure a RAID 10 setup will continue to function even if one site is unable to although our engineers at Nottingham Data Recovery know that in the event of such a failure occurring the remaining volumes are not protected from the possibility of a reboot or system crash.

At Nottingham Data Recovery our engineers have developed a method by which it is possible to reconstitute the data from a HP P4000 or P4500 series StoreVirtual setup even though HP the manufacturer say that this is impossible and the system is unrecoverable. Using a series of techniques specific to us we can reverse engineer using forensic methods and recover the data from the hard drives only (there is no need to send or work with the entire storage ‘node’) and save it to a new media.

In developing these methods our engineers at Nottingham Data Recovery are not only helping companies such as yours return to operational capacity in a shorter space of time but are also helping them to save important data that would otherwise be considered lost forever by many other data recovery companies and indeed Hewlett Packard themselves.

For more information on how we can help you recover the data you need from a malfunctioning HP P4000 or P4500 SAN call our engineers today on 0115 8220606. Our lines are open Monday to Friday 9am to 6pm as is our data recovery centre and our engineers are on hand to help you through the minefield of recovering your data from a storage cluster when generally it is considered impossible to do.

Can Data Recovery Software Help You During an Emergency?

Data recovery software is a very popular alternative to data recovery companies. Many feel that if they back their files up, or have this software on their computer, then they have nothing to worry about. Is their faith misplaced?

Not necessarily. Data recovery software can help you, but the type of help it can provide is limited at best. In most emergency situations, it may not provide the solution you are looking for.

How Data Recovery Software Works

Data recovery software only works on deleted files. When a file is deleted, that space is marked as available. This tells the computer that it has permission to overwrite the space with new data. It can do this at any given time.

The longer you wait to recover a file, the more of a chance this file will be overwritten. Once the space is overwritten, the deleted file is gone.
You cannot recover it, even with software.

The software scans your hard drive for files that have been deleted and can be recovered. You have to run it as soon as you figured out the file you needed was deleted. If you don’t, you run the risk of losing the deleted file forever.

Sometimes, even if you run the software immediately, your data simply cannot be recovered. If your computer won’t turn on, or won’t boot up properly, then you won’t be able to run any type of software. In these cases, your software is useless.

Your Complete Backup Plan

If you prepare for an emergency beforehand, you will be less likely to panic. Preparing for a computer emergency is just like preparing for a real life emergency: you need to have your plan in place and know how to execute it when disaster strikes.

This isn’t to say you shouldn’t have data recovery software on your computer. You should always have a backup plan. Data recovery software and an external hard drive may be part of your back up plan. A data recovery company should be part of it too. The company can help you to recover anything in case of an emergency.

Try to find a local data recovery Nottingham company. They should have a great success rate and plenty of customer testimonials on their website.
Make sure you know if the company will work on your computer. Some companies specialize only in PCs. If you need Mac recovery in Nottingham, you need to find a company that can help you.

Find and write down the company’s contact information in advance. You need to have it on hand when disaster strikes. When it happens, remain calm. Call the company and explain the situation. Follow their directions precisely. Working with them can help to relieve the stress that deleted files can give you.
