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 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."
"It results in more efficient storage utilization, cutting capital expenditure in half."
"The solution saves a lot of storage capacity."
"It is very easy to implement."
"The solution is stable."
"The most effective features for data deduplication are maximizing storage capacity and minimizing expenditure."
"If you have a large enough storage capacity then you can take an ample amount of data."
"HPE StoreOnce has high performance."
 

Cons

"I would like to see free disk space."
"The solution’s web access should be improved."
"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."
"This product would be improved with the inclusion of more features to security or WORM."
"Hardware maintenance involves some downtime for backup destination storage which can be a problem for some."
"Cloud integration needs to be simplified."
"The user interface of HPE StoreOnce is an area of concern where improvements are required."
"The cost is at the forefront of everyone's mind."
"I would like to see better integration with Veeam software."
"The product's price could be better."
 

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."
"HPE StoreOnce is cheaper compared to other solutions in the market."
"The solution's cost is above average."
"Price-wise, it comes with a high price tag when compared to other products."
"The solution is pretty expensive."
"With the same capacity of Data Domain and ExaGrid, which is 80 terabytes, HPE is the cheapest one."
"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."
"I think the product is competitive in terms of pricing. Other products like the one from Dell are costlier compared to the tool."
"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."
