HPE StoreOnce Review
With deduplication on the virtual tape library were achieving a compression ratio of 16:1 which means we can keep the backups for six months.


Valuable Features

Daily onsite backup, rapid data restore and reliable off site disaster recovery. HP deduplication technology can reduce the amount of backup data you need to store by up to 95 per cent and can deliver backup speeds of up to 100TB/hr.

Improvements to My Organization

  • It’s less mechanical so it’s writing to hard drives and we’ve had no problems with it whatsoever during the year we’ve been using it. It’s saved us so much time as well because we don’t have to troubleshoot the migrations every day. We know that those migrations are going to happen and that’s taken a weight off a lot of peoples’ minds, particularly those running our out of hours services.
  • We were creating so much data that even with two huge libraries and over 100 tapes, it only had the capacity to keep backups for three weeks. With deduplication on the virtual tape library it’s now achieving a compression ratio of 16:1 which means it can keep the backups for six months.
  • Deduplication also reduces the number of disks required which reduces space, energy and cooling costs.
  • Since the staged back-up happens in the background there is no impact on the network so back-up times are not an issue. However, even with the added work of deduplication, StoreOnce is delivering a transfer rate of up to 7GB/min.

Stability Issues

Since the staged back-up happens in the background there is no impact on the network.

Scalability Issues

Came with two additional enclosures to put the drives in and you can add another one. We ordered the additional enclosure, it arrived, we racked it up, connected it into the VTL and ran a command to say ‘recognise this enclosure - expand to this enclosure’ and it just did it. You don’t lose anything because the data that is on the existing enclosures just spreads out across the new enclosure.

Customer Service and Technical Support

Customer Service:

HP offered as much or as little support as we required so we did the implementation ourselves. It was checked over by an HP engineer and signed off in two weeks. HP provides support with a nine to five next business day callout. HP comes to visit us and we have conference calls, presentations and demonstrations. That is the kind of interaction we’re getting.

Technical Support:

HP provided a Webinar overview of the virtual tape library, gave us access to HP Labs and also sent in two technical specialists to talk through the product, demonstrate it and answer all our questions. However, what swung the deal for us was that we were able to have the kit on loan for up to three months. If you don’t like it HP come and remove the kit. If you do like it you just pay for it and keep it. That was brilliant because I didn’t want to go through the process of buying something and then find it didn’t operate in the way we wanted or was incompatible with certain backup software.

Previous Solutions

Our storage infrastructure was founded on an HP StorageWorks EVA 4400 disk array and when demand increased, a further EVA 6550 array was added.

Initial Setup

It integrates very well with our backup software. Creating a new VTL is very easy. You just go into the system and create the new library saying what kind of emulation you want, how many drives and how many tape cartridges and it creates it. It has a whole range of emulation types and most backup software will support one of the emulations that StoreOnce will use.

Implementation Team

We did the implementation ourselves.

ROI

We have not so far computed the amount of money saved but efficiency and service standards have certainly increased. Previously, if someone lost a file it could take 10 minutes to locate and load the appropriate tape. Now, the restore time is around five seconds.
