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

"The most valuable features of ExaGrid EX are the Veeam features and Landing Zone."
"Both the pricing and the performance are excellent."
"The initial setup is one of the most user-friendly B2B user solutions. It's good, it's easy. Deployment usually takes less than one day. You only need one person for deployment and maintenance."
"The deduplication feature in this product is amazing."
"If you have a large enough storage capacity then you can take an ample amount of data."
"Recovery is important."
"Based on customer feedback, I rate it highly as one of the most stable products in the backup and archiving line compared to offerings like Data Domain or from Huawei and Lenovo."
"The most valuable feature of the solution is its UI. The product's UI makes it easy for users to configure the tool."
"It is very easy to implement."
"Catalyst backup is used to back up Oracle databases, and provides very good throughput during backups."
 

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."
"The platform's price could be lower."
"Cloud integration needs to be simplified."
"They could provide more options for storage capacity."
"HPE StoreOnce needs to be made cheaper than products from Dell and Veeam."
"Its customer service could be faster."
"The solution would be improved if it could also be used as a data store for VMware."
"The cost is at the forefront of everyone's mind."
 

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."
"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."
"The price puts me off. It's definitely on the high side."
"I rate the platform's pricing a seven out of ten."
"There are costs for additional storage and space."
"HPE StoreOnce is cheaper compared to other solutions in the market."
"The price of the product is reasonable."
"Price-wise, it comes with a high price tag when compared to other products."
