Maximized storage capacity and minimized costs and an easy setup
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
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 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."
"It's easy to backup data, manage. A"
"The initial setup process is simple."
"From a centralized system, I can manage the interface, the backup policies, and the status of the database."
"The solution's licensing policy is more practical and not confusing."
"Catalyst backup is used to back up Oracle databases, and provides very good throughput during backups."
"The solution is stable."
"Quick 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

"We have lost some market due to the minimum capacity now being 80 terabytes."
"HPE StoreOnce could improve the capacity support."
"We're outsourced with a partner who recalls a larger amount of problems with the stability of the product."
"The setup phase is not so simple that an end user can plug and play to make it operational."
"We do not foresee the need to have an artificial intelligence app. It is not mature enough."
"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."
"While the solution does everything expected, it would be beneficial if AI could be integrated for optimization and monitoring."
"The product's price could be better."
"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

"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."
"Price-wise, it comes with a high price tag when compared to other products."
"I would rate it around two or three because, compared to others, it tends to be higher priced."
"The price of the product is reasonable."
"I think the product is competitive in terms of pricing. Other products like the one from Dell are costlier compared to the tool."
"We have got a perpetual license, and we have access to all the features. If you are using cloud banks, you can store the internal data in HPE Cloud if needed. 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."
"With the same capacity of Data Domain and ExaGrid, which is 80 terabytes, HPE is the cheapest one."
"I rate the platform's pricing a seven out of ten."
"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."
