Quotes from Members

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

Pros

"Both the pricing and the performance are excellent."
"The most valuable features of ExaGrid EX are the Veeam features and Landing Zone."
"The implementation is not that complex for someone who has experience."
"The important feature is compression and duplication. It has a good compression ratio and is very stable."
"It is very easy to implement."
"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."
"The product’s data retention is very good."
"Deduplication and compression are in a good ratio. It supports the HPE Catalyst protocol, which is much faster than NFS and other protocols. We use CommVault and Veeam, and these two solutions support the Catalyst protocol very well and are integrated at high speed. It is faster than normal access."
"The implementation is straightforward."
"I think the most valuable feature is the catalyst technology, which is in the StoreOnce appliance."
 

Cons

"The solution’s web access should be improved."
"I would like to see free disk space."
"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."
"HPE should have more options so customers can choose from a wide range of products with small to big capacities."
"In terms of areas for improvement, I believe HPE StoreOnce could learn from competitors like Dell's Data Domain and ExtraHop in refining its architecture."
"HPE StoreOnce needs to be made cheaper than products from Dell and Veeam."
"The product's support is an area with certain shortcomings requiring improvements. Support needs to be faster."
"I would like to see better integration with Veeam software."
"The web interface, ease of use, and GUI all need to be improved."
 

Pricing and Cost Advice

"I rate ExaGrid EX ten out of ten for pricing."
"The renewal fee is approximately $3,500 to $3.750 for a 60 terabyte device."
"The licensing costs is capacity-based and come bundled with support."
"The solution is pretty expensive."
"The licensing schemes could improve in HPE StoreOnce and the price is high. They should reduce the price."
"The solution's cost is above average."
"The product is not expensive. It is available at a good price."
"I rate the platform's pricing a seven out of ten."
"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 would rate it around two or three because, compared to others, it tends to be higher priced."
