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."
"Technical support is quite good."
"The implementation is straightforward."
"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 solution's most valuable feature is its catalyst mode, along with better performance, backup, and recovery."
"HPE StoreOnce is particularly useful in situations where organizations require a backup solution to store their data. Its deduplication feature is quite impressive, providing a deduplication ratio of around 25 to 26."
"The most valuable feature of the solution is its UI. The product's UI makes it easy for users to configure the tool."
"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."
"HPE StoreOnce works well, it is stable."
 

Cons

"The solution’s web access should be improved."
"I would like to see free disk space."
"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."
"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."
"HPE should have more options so customers can choose from a wide range of products with small to big capacities."
"improvement? HPE StoreOnce has a limitation with respect to controllers. Other tools offer more than one controller. I feel that the high availability of the view controller should be redundant. The tool’s control and UI part should be improved and made more advanced. The feature that helps with the manual movement of tapes should also be improved."
"The user interface of HPE StoreOnce is an area of concern where improvements are required."
"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."
"The product could be improved with better support for data protection."
 

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 schemes could improve in HPE StoreOnce and the price is high. They should reduce the price."
"I think the product is competitive in terms of pricing. Other products like the one from Dell are costlier compared to the tool."
"There are costs for additional storage and space."
"The price of the product is reasonable."
"The licensing costs is capacity-based and come bundled with support."
"Price-wise, it comes with a high price tag when compared to other products."
"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 cost of HPE StoreOnce is very expensive."
