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 deduplication feature in this product is amazing."
"The initial setup process is simple."
"I think the most valuable feature is the catalyst technology, which is in the StoreOnce appliance."
"Recovery is important."
"The implementation is not that complex for someone who has experience."
"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."
"HPE StoreOnce is an easy-to-use tool."
"The solution's most valuable feature is its catalyst mode, along with better performance, backup, and recovery."
"I am impressed with the tool's technical alliance with Veeam and Veritas."
"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."
 

Cons

"HPE StoreOnce could improve the capacity support."
"The dashboard needs more improvement."
"We would like to see some improvements in the Veeam Backup & Replication integration. It's good, but it has a lot of room to improve. In particular around the inability to easily move data between StoreOnce appliances."
"I would like to see an emphasis placed on making data deduplication and compression more powerful."
"It is difficult to solve issues with this solution remotely. I prefer to use the knowledge base platforms. The response time could improve."
"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."
"We stopped investigating because we were not really happy with the application."
"The latency is a bit high."
"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 licensing costs is capacity-based and come bundled with support."
"I think the product is competitive in terms of pricing. Other products like the one from Dell are costlier compared to the tool."
"Price-wise, it comes with a high price tag when compared to other products."
"The solution's cost is above average."
"I rate the platform's pricing a seven out of ten."
"There are costs for additional storage and space."
"The price of the product is reasonable."
"The price puts me off. It's definitely on the high side."
"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."
