Quotes From Members
We asked business professionals to review the solutions they use.
Here are some excerpts of what they said:
"The most valuable feature is the performance because you can back up data really quickly.""The solution is very stable.""The hardware can operate in high temperatures, in case of any disaster.""I like the different features. We work closely with Dell on different products and features, which is why we use them all.""The most valuable feature is the inline data deduplication.""It is very fast as compared to the other competitors. Its simplicity and bit rate are also valuable. It takes less time if we compare it with the old solution that we have.""Dell PowerProtect DD is a stable solution.""The stability is excellent."

More Dell PowerProtect DD (Data Domain) Pros →

"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.""The most valuable features are the deduplication and compression capabilities.""HPE StoreOnce has high performance.""The scalability is very good.""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.""If you have a large enough storage capacity then you can take an ample amount of data.""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 solution is stable."

More HPE StoreOnce Pros →

"They need to make migration easier.""The price of the product is high.""Its management can be improved.""When you use Data Domain, you have to have at least 20% free space so it can work properly. Sometimes we struggle with that, because we wanted to use all the free space, but then Data Domain becomes really slow. I understand that 20% is needed to process all the data, and doing the duplication and compression and all that, but it would be a big improvement if they did not require that 20%, because it is just too much to have available.""I would like to see some kind of integration with the ransomware in the next release.""They still have hardware different from the software.""The price could be improved.""I would like to see better integration and support for backing up to cloud providers such as Alibaba Cloud."

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.""The solution could always be less expensive.""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.""The GUI and its user-friendliness have some room for improvement.""Cloud integration needs to be simplified.""The web interface, ease of use, and GUI all need to be improved."

  • "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."

  • "Price-wise, it comes with a high price tag when compared to other products."
  • "The cost of HPE StoreOnce is very expensive."

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."
