A scalable solution with Veeam and Vertias alliance

Quotes from Members

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

Pros

"The important feature is compression and duplication. It has a good compression ratio and is very stable."
"The interface is very user-friendly."
"Catalyst backup is used to back up Oracle databases, and provides very good throughput during backups."
"The most effective features for data deduplication are maximizing storage capacity and minimizing expenditure."
"Currently, VTLs can only be created on individual service sets and cannot be used to share the resources of other nodes."
"Quick recovery."
"The product’s data retention is very good."
"The most valuable features are the deduplication and compression capabilities."
"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 should have more options so customers can choose from a wide range of products with small to big capacities."
"The solution's pricing could be improved."
"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 repository should have an extension to connect to the cloud and deposit the backups."
"The solution's technical support should be faster."
"While the solution does everything expected, it would be beneficial if AI could be integrated for optimization and monitoring."
"The solution could always be less expensive."
"The solution would be improved if it could also be used as a data store for VMware."
"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."
"The product needs to improve performance while scaling out. It also needs to improve stability."
 

Pricing and Cost Advice

"Price-wise, it comes with a high price tag when compared to other products."
"The price puts me off. It's definitely on the high side."
"I rate the product's pricing a seven out of ten."
"The product is not expensive. It is available at a good price."
"I rate the platform's pricing a seven out of ten."
"The cost of HPE StoreOnce is very expensive."
"I would rate it around two or three because, compared to others, it tends to be higher priced."
"The product's pricing is medium."
"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."
