A highly scalable and easy-to-install solution that can be used for DLP
I used ExaGrid EX as a strategy for DLP for an Oracle database ExaGrid EX was very helpful because I had a lot of issues with the original storage, which was HPE StoreOnce. The most valuable features of ExaGrid EX are the Veeam features and Landing Zone. The solution’s web access should be…

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 initial setup is simple."
"Recovery is important."
"The initial setup process is simple."
"The solution is stable."
"The solution's most valuable feature is its catalyst mode, along with better performance, backup, and recovery."
"The most valuable features are the deduplication and compression capabilities."
"I like the tool’s deduplication feature. We get a ratio of 9:1 for deduplication. The product is also Linux based. Last year, our organization faced some virus attacks. However, the backup was safe because of the product being a Linux version. HPE StoreOnce is a secure product."
"The most valuable feature of the solution is its UI. The product's UI makes it easy for users to configure the tool."
 

Cons

"I would like to see free disk space."
"The solution’s web access should be improved."
"Hardware maintenance involves some downtime for backup destination storage which can be a problem for some."
"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 better integration with Veeam software."
"The product could be improved with better support for data protection."
"The solution could always be less expensive."
"The user interface of HPE StoreOnce should be more user-friendly. Additionally, the configuration and troubleshooting could be better."
"When it comes to upgrading, it always goes block-wise. One block is 48 TB raw capacity. It would be good if they can include a smaller capacity for SMB customers. Currently, it is not possible to increase in a smaller capacity. You have to buy the exact same unit. It would be great if they can provide a smaller next block. There are around 20 hard disks, and it would be really helpful if we can add 10 hard disks initially and 10 hard disks later."
"The GUI and its user-friendliness have some room for improvement."
 

Pricing and Cost Advice

"The renewal fee is approximately $3,500 to $3.750 for a 60 terabyte device."
"I rate ExaGrid EX ten out of ten for pricing."
"Price-wise, it comes with a high price tag when compared to other products."
"The solution's cost is above average."
"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."
"The price puts me off. It's definitely on the high side."
"With the same capacity of Data Domain and ExaGrid, which is 80 terabytes, HPE is the cheapest one."
"The product's pricing is medium."
"I rate the product's pricing a seven out of ten."
"The cost of HPE StoreOnce is very expensive."
