Most of our client base is between fifty to five hundred end users. We occasionally recommend high-end HPE products for larger clients needing performance and reliability. Our clients predominantly use HPE StoreOnce for small business purposes in industries like dairy and finance Our clients have…

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 most valuable features for us are the ease of use, the reliability, and the exceptional deduplication that we get across that data that we store on those devices."
"It's easy to backup data, manage. A"
"The product's most valuable feature is stability."
"The initial setup process is simple."
"Quick recovery."
"HPE StoreOnce has high performance."
"The most effective features for data deduplication are maximizing storage capacity and minimizing expenditure."
"Technical support is quite good."
"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

"Some high-level cybersecurity features could be achieved with some entities, and their integration could be built into the store."
"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."
"Hardware maintenance involves some downtime for backup destination storage which can be a problem for some."
"HPE StoreOnce Backup to Disk (BTD) is not a good backup solution for NAS devices. It does not have a dual controller, so if one controller fails, the entire system will go down."
"The solution would be improved if it could also be used as a data store for VMware."
"I would like to see better integration with Veeam software."
"The user interface of HPE StoreOnce should be more user-friendly. Additionally, the configuration and troubleshooting could be better."
"This product would be improved with the inclusion of more features to security or WORM."
"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

"I rate the platform's pricing a seven out of ten."
"There are costs for additional storage and space."
"The licensing costs is capacity-based and come bundled with support."
"The product's pricing is medium."
"The solution is pretty expensive."
"The licensing schemes could improve in HPE StoreOnce and the price is high. They should reduce the price."
"Price-wise, it comes with a high price tag when compared to other products."
"To be honest, we were quite happy with the price, but we always want things cheaper than they are. I think for what we got, we felt that the price was quite reasonable comparing it to other products that provide that same level of functionality."
"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."
