Q&A Highlights
Question: Compare EMC Data Domain and HPE StoreOnce. Which is better?
Answer: I have used DataDomains for many years now. Once you get over the initial price tag and look at cost/TB (realised), it really is good value. The features in the newer DDOS versions match or are better than anything else I have ever seen/heard of. I have several sites that have dedup ratios of 60:1 or even 100:1 (ok: 99:1). The Data Domains I have installed and maintain are all very reliable. My experience with HPE StorOnce is the exact opposite: Poor dedup ratio, limited compatibility, and not that reliable. The answer is: You get what you pay for.
Featured Review
Quotes From Members
We asked business professionals to review the solutions they use.
Here are some excerpts of what they said:
"It's very competitive in terms of the price and technology. Also, the development team continuously makes updates. The data reduction feature is very useful.""The feature that I have found most useful is its data duplication.""The most valuable features of Dell EMC PowerProtect DD are the duplication security and uptime.""The solution is very scalable.""It works within backup windows and has got good deduplication.""It is a stable solution.""I find the data to be most valuable.""The most valuable feature is the inline data deduplication."

More Dell PowerProtect DD (Data Domain) Pros →

"Deduplication is the most valuable feature.""HPE StoreOnce has high performance.""The most valuable feature of HPE StoreOnce is the virtual drive.""The solution is stable.""Deduplication and compression are in a good ratio. It supports the HPE Catalyst protocol, which is much faster than NFS and other protocols. We use CommVault and Veeam, and these two solutions support the Catalyst protocol very well and are integrated at high speed. It is faster than normal access.""The initial setup is one of the most user-friendly B2B user solutions. It's good, it's easy. Deployment usually takes less than one day. You only need one person for deployment and maintenance.""The scalability is very good.""The hardware is strong and all the equipment has a good infrastructure. Personally, I think it's the best storage product in HPE for small to medium-sized businesses."

More HPE StoreOnce Pros →

"The price of the product is high.""They still have hardware different from the software.""It can probably have integration with other OEMs. It should also have more features for ransomware protection.""The price could be a little cheaper than it is now.""The software from Dell that can be used to operate Data Domain needs to have enhancements made to the user interface. It is too complex.""The size and scale of the product are limited and could be improved.""Data Domain lacks compatibility with fiber channels and tapes. We can't use it with a tape library. That's an issue in Latin America sometimes because a lot of clients still use tapes for budget reasons. Maybe they have a lot of archives. In North America and Europe, they do a lot of archiving, but they use the cloud more than we do. Sometimes we have to put together a Frankenstein where we connect another server to the tape library and send all the data there.""They need to make migration easier."

More Dell PowerProtect DD (Data Domain) Cons →

"One item I wanted to see is SSD drives as a cache, and that was, for a time, still lacking in StoreOnce, however, they have done it now. It's not available yet, however, it will be shortly.""The user interface of HPE StoreOnce should be more user-friendly. Additionally, the configuration and troubleshooting could be better.""HPE StoreOnce should come with a detailed installation guide.""Cloud integration needs to be simplified.""The solution could always be less expensive.""HPE StoreOnce could improve the capacity support.""When it comes to upgrading, it always goes block-wise. One block is 48 TB raw capacity. It would be good if they can include a smaller capacity for SMB customers. Currently, it is not possible to increase in a smaller capacity. You have to buy the exact same unit. It would be great if they can provide a smaller next block. There are around 20 hard disks, and it would be really helpful if we can add 10 hard disks initially and 10 hard disks later.""The solution should continue to refine its integration capabilities. I also see they are starting to use cloud integration as well, which is good, but they should do more to integrate with it."

Pricing and Cost Advice
  • "Its price is reasonable."
  • "It could be more competitively priced. Its licensing was for five years. Obviously, the support will get renewed at some stage, but that's it."
  • "The price is on the high side."
  • "Becoming more expensive."
  • "The solution is expensive. However, if you pay less you receive less, it is cost-effective."
  • "Pricing for this product could still be improved, though several years ago, its price was very high. When buying an IDPA product such as Dell EMC PowerProtect DD (Data Domain), you don't have to buy anything else, because you'll have an integrated solution: a data domain appliance plus software."
  • "The price of Dell EMC PowerProtect DD could improve, it is expensive."
  • "The price of the backup appliance is slightly expensive. Compared to other vendors, the pricing will be slightly higher."
  • More Dell PowerProtect DD (Data Domain) Pricing and Cost Advice →

  • "We have got a perpetual license, and we have access to all the features. If you are using cloud banks, you can store the internal data in HPE Cloud if needed. You can offload the data to the HPE Cloud. It is a licensed product. We have got around 10 TB of cloud bank storage with a one-time payment. We specifically took 10 TB for very critical offsite backups. We can also increase it in blocks if needed."
  • "The licensing schemes could improve in HPE StoreOnce and the price is high. They should reduce the price."

    DataDomain is a very good product, compressing and deduplicating the data that is backed up. However it is desperately slow when it comes to restoring the data, I have it in use with Veeam Backup and it has caused us many problems due to the slow recovery of virtual machines or the writing to the tapes.

    Because of the good deduplication it has, DataDomain is a good hardware but only to be used as historical backups.

    HPE StoreOnce the short time you used it, it was pretty good in the times of backups and restore. It gives you the option of being able to divide your total storage capacity either by LAN or SAN with deduplication or by a CIF network.

    If you are looking for good speed times in your backups and restore, I would recommend using silly repositories (without deduplication).

    I know most about the StoreOnce.

    I like values for that it is really fast also when rehydrating/undeduping the data and it has extremely good dedupe ratio.
    The catalyst replication of data known to the supported backup ISVs using intelligent WAN accelaeration is also very nice.

    HPE Recovery Manager Central for flat disaster backup/recovery running without Backup ISV is another feature that I like to use. This can be up to 23 times faster backup and 15 times faster restore.

    it_user703191 - PeerSpot reviewerit_user703191 (User)

    I'm working with both.
    Bottom line – both show equivalent deduplication ratio in same backup jobs.
    The difference in software and environment.
    Because my company is using 3PAR storage, I think the right solution to use for integration is VMWare+3par+Storeonce (RMC).
    Also, ZIM using Oracle Exadata, in this case, I prefer Data Domain.
    DELL EMC provides much better support and service.
    HPE StoreOnce cheaper.

    I have had great success with Data Domain, having used them at two Fortune 100 companies. They are extremely reliable, especially when it comes to end-to-end data integrity checking. It provides tremendous flexibility, and when used for backups, It integrates with backup products like Networker, Veeam, Veritas NetBackup, Avamar, vSphere Data Protection Advanced and HP Data Protection, CommVault Simpana and Pivotal Greenplum. There are also boost products for Enterprise applications which provides a very powerful integration, with very high performance for Oracle RMan, SQl-SVR, SAP, SAP HANA< IBM DB2, HortonWorks and Cloudera.

    With a feature called ProtectPoint, I was able to backup an 15TB Oracle DB, using RMAN, in about 1 hour to a VMAX array!! And also the restore was completed in roughly the same time.

    There is also a software defined Data Domain that runs under VMware. They also have software to offload data to a Private, Public or Hybrid Cloud.

    Two other use cases that I used it for were: a tier-3 NFS file share. Data Domain provides a standard NFS interface that can be used to build file shares that are hardware deduped for low cost.

    Finally, I also used it as a 17a4 Compliance Worm device. It is fully compliance with the SEC 17a4 spec, as well as HIPPA and other WORM archival requirements.

    BOTTOM LINE - my experience has been: Very fast, very reliable, extremely flexible with multiple use cases. Not just for backups.

    We have had very good success with the HPE StoreOnce product line. It usually comes in priced lower than the Data Domain solution. Getting up to 20 and 30 to 1 dedupe.

    it_user678954 - PeerSpot reviewerit_user678954 (Systems Integrator with 1,001-5,000 employees)

    It depends on the backup software, data domain and networker achieves very high levels of deduplication which reduces the backup window and makes backup more effective.

    EMC Data Domain.
    This is a proven technology which has addressed most issues and is extremely stable

    Real User

    Not get much experience for the comparison. Since those dedupe software have not certified Huawei OceanStor Storage devices.
    I would like to value more if someone can introduce a channel to get our Storage worked together with EMC DD and HPE StoreOnce.
