A scalable solution with Veeam and Vertias alliance
I am impressed with the tool's technical alliance with Veeam and Veritas.  The product needs to improve performance while scaling out. It also needs to improve stability.  I have been using the product since seven years.  I would rate the product's stability a nine out of ten. I would rate the…

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"The stability of the solution is excellent."
"The valuable feature is the ability to work with the Veeam software to reduce the backup windows."
"The solution is stable."
"Technical support is quite good."
"I think StoreOnce's deduplication technology is crucial for cost efficiency and faster recovery, especially for backup and data protection purposes."
"The important feature is compression and duplication. It has a good compression ratio and is very stable."
"Recovery is important."
"It is a very scalable solution."
"While the challenges posed by the difficulties were significant, they prompted the replacement of problematic components, resulting in the resolution of issues. Importantly, there were no substantial ongoing concerns. Regarding the overall performance, it has been consistently excellent."
"I am impressed with the tool's technical alliance with Veeam and Veritas."
 

Cons

"HPE StoreOnce should come with a detailed installation guide."
"We archive our backups on tape, so I feel like if we could somehow plug our tape drive directly into the StoreOnce device and set it up to where it would archive based on, if some kind of rules based engine or what have you, that would really be an improvement for us."
"The solution's technical support should be faster."
"The platform's price could be lower."
"We have lost some market due to the minimum capacity now being 80 terabytes."
"The user interface of HPE StoreOnce should be more user-friendly. Additionally, the configuration and troubleshooting could be better."
"Cloud integration needs to be simplified."
"The product could be improved with better support for data protection."
"The product needs to improve performance while scaling out. It also needs to improve stability."
"Perhaps the most notable area for enhancement lies in the web interface for management. The current limitations in LDAP editing capabilities are not addressed in the UI, and I haven't observed any recent updates. It's possible that the new version of the DXI service incorporates improvements in the GUI, but I cannot confirm. While there is room for improvement in the current GUI, it remains a relatively minor issue. Overall, the system is comprehensive, covering aspects such as reports on latency and networking, leaving little room for additional enhancements in those areas."
 

Pricing and Cost Advice

"The product's pricing is medium."
"I would rate it around two or three because, compared to others, it tends to be higher priced."
"The cost of HPE StoreOnce is very expensive."
"With the same capacity of Data Domain and ExaGrid, which is 80 terabytes, HPE is the cheapest one."
"The solution is pretty expensive."
"The price puts me off. It's definitely on the high side."
"The solution's cost is above average."
"The licensing schemes could improve in HPE StoreOnce and the price is high. They should reduce the price."
"I do not oversee this aspect, as pricing is contingent on factors such as volume, technical specifications, and the desired features. Consequently, I lack information on the pricing details and structure."
