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.
Pros and Cons
  • "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."

    What is most valuable?

    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.

    How has it helped 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.

    What do I think about the stability of the solution?

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

    What do I think about the scalability of the solution?

    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.

    885,264 professionals have used our research since 2012.

    How are customer service and 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.

    Which solution did I use previously and why did I switch?

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

    How was the 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.

    What about the implementation team?

    We did the implementation ourselves.

    What was our 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.

    We were previously using a different solution but our storage needs grew.
    Pros and Cons
    • "If you want a reliable and reasonably-priced product, I would recommend it."
    • "The one issue I have is the maintenance package – it's very expensive."

    What is most valuable?

    It performs pretty well with minimal to no issues.

    How has it helped my organization?

    It has allowed us greater storage with a reduced footprint. It also works well with our servers – including our Dell servers. It was important that we have an integrated environment.

    What needs improvement?

    We had some initial driver issues, but I think the newer release has changed all that. The one issue I have is the maintenance package – it's very expensive. If I were to renew it, it would remain expensive and not cost effective. The initial proposal was inconsistent with what I found in terms of maintenance and renewal costs. A break/fix-type package would be better.

    For how long have I used the solution?

    I've used it for four years.

    What do I think about the stability of the solution?

    It is pretty stable; excellent, in fact. I had one very minimal hard-drive failure.

    What do I think about the scalability of the solution?

    We recently added more and it went very well. It's easy to add to this product.

    How are customer service and technical support?

    8/10 for both. Issues were dealt with quickly and efficiently.

    Which solution did I use previously and why did I switch?

    We were previously using a different solution but our storage needs grew and we decided we needed a new solution.

    How was the initial setup?

    It was straightforward.

    What about the implementation team?

    We had an HP engineer come in for implementation. He was excellent.

    Which other solutions did I evaluate?

    Dell and IBM. We chose HP because of the price and the vendor support.

    What other advice do I have?

    The two things that we looked at were performance and cost.

    This particular product is stable, and the support has been good. If you want a reliable and reasonably-priced product, I would recommend it.

    The greatest benefit to us has been lower costs than our previous solution.
    Pros and Cons
    • "Most important criteria to look for includes: Price, features, functionality, and ease of use; definitely look at this solution as a viable option as it is cost effective and reliable."
    • "I'd like to see the following features added in: More detailed reporting, more granular reporting, and more features in the CLI."

    What is most valuable?

    • Redundancy
    • Ease of use
    • Scalability
    • Disaster recovery

    How has it helped my organization?

    The greatest benefit to us has been lowering costs.

    What needs improvement?

    I'd like to see the following features added in:

    • More detailed reporting
    • More granular reporting
    • More features in the CLI

    What do I think about the stability of the solution?

    Excellent.

    What do I think about the scalability of the solution?

    Excellent.

    How are customer service and technical support?

    Excellent. There has been an integrated partnership with the ability to answer any and all questions.

    Which solution did I use previously and why did I switch?

    We were using a different solution, but it was too costly so we needed to switch.

    How was the initial setup?

    The initial setup was straightforward. HP took a hands-off approach, which was good, and they let us do a lot of it on our own. We therefore didn’t have to do cross-training and we were able to do a lot of trial and error, which was good for us as well.

    Which other solutions did I evaluate?

    We also looked at EMC.

    What other advice do I have?

    Most important criteria to look for includes:

    • Price
    • Features
    • Functionality
    • Ease of use

    Definitely look at this solution as a viable option as it is cost effective and reliable.

    The most valuable feature is the deduplication ability, but file sharing is also really good.
    Pros and Cons
    • "The most valuable is the deduplication ability, but file sharing is also really good."
    • "StoreOnce doesn’t work for our class of data, which is small, and needs to include more genomic and medical research as test cases."

    What is most valuable?

    The most valuable is the deduplication ability, but file sharing is also really good.

    How has it helped my organization?

    We saw less capital outlay after implementing the solution.

    What needs improvement?

    For subsequent models, I would like HP to improve deduplication rations for tiny files numbering near a trillion, which they do in our business. StoreOnce doesn’t work for our class of data, which is small, and needs to include more genomic and medical research as test cases.

    For how long have I used the solution?

    I have been using StoreOnce D2D for four years.

    What do I think about the stability of the solution?

    Stability was good but undersized for what we needed. We weren't able to de-duplicate what we needed.

    What do I think about the scalability of the solution?

    It was not able to scale for us; we had to buy another solution (X9000) to store copies.

    How are customer service and technical support?

    I found HP to be helpful, but they asked too many questions and were not really able to help our business.

    Which solution did I use previously and why did I switch?

    We were in need of backing up petabytes of data for medical databases.

    How was the initial setup?

    We had experience with the solution, so it was relatively simple.

    Which other solutions did I evaluate?

    • EMC
    • Comvault

    What other advice do I have?

    The most important criteria for us is reliability.

    If you work for a medical research institute or something with very small files, then this solution may not be for you. Your best move is to do a POC.

    We are able to reduce the amount of backup tapes we need.
    Pros and Cons
    • "With D2D2T appliance, and backup jobs reconfiguration we are reducing the backup tapes count, as the appliance offers a fast backup and restore process and a data replication mechanism to a remote site location that ensures data center backups disaster recovery."

      What is most valuable?

      • Faster backup and restore process
      • Data de-duplication mechanism

      How has it helped my organization?

      With D2D2T appliance, and backup jobs reconfiguration we are reducing the backup tapes count. The appliance offers a fast backup and restore process, and a data replication mechanism to a remote site location. This ensure data center backups disaster recovery.

      What needs improvement?

      • Data capacity graphical interface

      For how long have I used the solution?

      I've used it for three years.

      What was my experience with deployment of the solution?

      No issues during the deployment.

      What do I think about the stability of the solution?

      No issues encountered.

      What do I think about the scalability of the solution?

      Which solution did I use previously and why did I switch?

      This is the first solution we have implemented.

      How was the initial setup?

      It was straightforward, because we had chosen the right template for our needs and all the connectivity was prepared before the device was on site.

      What about the implementation team?

      It was implemented through the local HP support team. They provided us with excellent support and knowledge of the product technology.

      What other advice do I have?

      Always follow the vendors best practice and guidance to avoid any problems.

      The cost savings of not having to continually purchase additional shelf space has been the driving force of staying with this product.
      Pros and Cons
      • "The deduplication feature is awesome; the storage space has been cut down by at least 50% and on some instances greater reduction has been achieved."
      • "The auto load balancing between VTL Libraries has been not as efficient as it should have been."

      What is most valuable?

      The deduplication feature is awesome. The storage space has been cut down by at least 50% and on some instance greater reduction has been achieved. Here is a current example showing the space savings: Actual User Data Store 44.9TB, Actual Size on Disk 4.0TB with an 11.3 dedupe ratio. This was only one of my libraries on the StoreOnce 4430 device.

      How has it helped my organization?

      Please refer to the answer above about valuable features. The space saving on storage of actual user data also has a cost savings attached to it. We do not have to extend the actual storage space as quickly now due to the space savings of the deduplication feature.

      What needs improvement?

      The auto load balancing between VTL Libraries has been not as efficient as it should have been. I have manually load balanced between my libraries to maintain a tight control.There have also been bug fixes in the past for their auto load balancing feature. I would like to see this greatly improved so that I feel that it is trustworthy enough to utilize this feature.

      For how long have I used the solution?

      I've used it for one and half years in an enterprise environment with HP DataProtector v7.0

      What was my experience with deployment of the solution?

      No issues during deployment of the 4430 device into the enterprise environment.

      What do I think about the stability of the solution?

      Not with this current model 4430, but with a previous model we did have stability issues and these have been resolve with the 4430 model.

      What do I think about the scalability of the solution?

      No issues with scalability. We purchased an additional 20TB shelf with the 4430 device (which came with a 20TB shelf included in the package we purchased).

      How are customer service and technical support?

      Customer Service:

      HP’s customer service is outstanding. Turnaround time on parts for us is four hours and we also have them in less time than that. The HP service representatives are knowledgeable, friendly and are very easy to speak to. They are people who don't read from a script, but actually have a working knowledge of the equipment.

      Technical Support:

      It's outstanding.

      Which solution did I use previously and why did I switch?

      No, and we chose StoreOnce as we are currently an HP enterprise environment.

      How was the initial setup?

      In most ways it was straightforward, however, you need to be an experienced network administrator to install this device.

      What about the implementation team?

      It was done as an in-house implementation. However, we currently work with an HP partner in all our enterprise purchases. They're called High Performance Technologies, Inc. in Palm City, Florida, and the IT team at this business are outstanding and they all keep up to date with their HP certifications. They work with HP to obtain the best pricing for the equipment we need to ascertain. With this business relationship, comes years of trust and we know that they understand our enterprise network topology and make recommendations based off that long term knowledge.

      What was our ROI?

      The cost savings of not having to continually purchase additional shelf space has been the driving force of staying with this outstanding product.

      What's my experience with pricing, setup cost, and licensing?

      The original cost was approximately $250,000. Included in that was the device itself and 40TB of storage space.

      Which other solutions did I evaluate?

      We did evaluate other options but due to the fact that HP has set the standard, we stayed with them.

      What other advice do I have?

      I've had little to no issues with either the StoreOnce 4430 device or the DataProtector software. I would highly recommend this type of backup system for enterprise environments.

      Read the documentation provided by HP on their website and research the web to avoid any possible issues during implementation.

      When using the dedupe feature, backups take up less space than they previously did.
      Pros and Cons
      • "When using de-duplication, backups take less space than they previously did, and this minimizes the costs to our company."
      • "We're unable to expand our storage capabilities smoothly."

      What is most valuable?

      De-duplication is valuable because it is a technique to take backups of unique data only. We have to do backups on a daily and weekly basis, where the daily one is incremental and the weekly one is a full backup. When we ran this type of backup on a physical cartridge, it would take up a huge amount of space as there is no de-dupe with cartridges. When using de-dupe, backups take less space than they previously did, and this minimizes the costs to our company.

      How has it helped my organization?

      The de-duplication feature saves us storage space.

      What needs improvement?

      The performance could be improved.

      For how long have I used the solution?

      I've been using it for one and a half years.

      What was my experience with deployment of the solution?

      No issues encountered.

      What do I think about the stability of the solution?

      No issues encountered.

      What do I think about the scalability of the solution?

      We're unable to expand our storage capabilities smoothly.

      How are customer service and technical support?

      Customer Service:

      It's good.

      Technical Support:

      We are not getting any direct support from HP, but we are getting support from their partner. The support is relatively good.

      Which solution did I use previously and why did I switch?

      This is the first solution that we have used.

      How was the initial setup?

      It is straightforward.

      What about the implementation team?

      We used a vendor team who were 8/10.

      Which other solutions did I evaluate?

      This was done by the planning team.

      What other advice do I have?

      I recommend using the upgraded version of this product.

      We switched to HP because we needed a VTL solution with deduplication.
      Pros and Cons
      • "VTL with deduplication because with deduplication, you can have spare storage space."
      • "In the beginning, we had a lot of problems with bad firmware."

      What is most valuable?

      VTL with deduplication because with deduplication, you can have spare storage space.

      What needs improvement?

      Interoperability with other vendors backup software.

      For how long have I used the solution?

      I've used it for two and a half years.

      What was my experience with deployment of the solution?

      In the beginning, we had a lot of problems with bad firmware.

      What do I think about the stability of the solution?

      We had problems with the various firmware versions.

      What do I think about the scalability of the solution?

      No issues scaling the product.

      How are customer service and technical support?

      How was the initial setup?

      It was simple, especially to integrate it with our existing EMC network solution.

      What about the implementation team?

      We implemented it in-house.

      Which other solutions did I evaluate?

      We also looked at EMC DataDomain. We chose StoreOnce because it was cheaper by more than 60,000 Euros.
