Featured Reviews

Rastislav Maniak - PeerSpot reviewer
Improves backup and recovery time and integration with other products is good
The tool reduces storage footprint. However, clients are now storing data for longer durations with increasing requirements to retain backups for longer periods, particularly as a defense against ransomware attacks. As a result, the retention zone with duplicated data is experiencing more demand, leading to space constraints. This necessitates using higher-end, more expensive models to address the issue. I was asking about the mutual appliance, which would provide the same features as the integrated client without the hardware. This would allow it to be used in the public cloud, which I heard might be available soon. However, the private cloud is not reliable.

Maximized storage capacity and minimized costs and an easy setup
Most of our client base is between fifty to five hundred end users. We occasionally recommend high-end HPE products for larger clients needing performance and reliability. Our clients predominantly use HPE StoreOnce for small business purposes in industries like dairy and finance Our clients have…

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 feature is the ease of use and data deduplication. It's extremely easy to use and does a very good job of data deduplication and compression."
"It is a solid and a quite simple solution, which is a good combination. The customers like the simplicity and its scale-out capacity. They like the support pricing, and even the extension capacity pricing, a fixed price, which the executive is offering in Czech market."
"The most valuable features of the solution are deduplication and landing zone."
"One of the main features is the landing zone, it is a particular space where the information is not duplicated."
"The tool has improved backup and recovery times. One of the key features contributing to this improvement is the landing zone and deduplication retention zone. When data is in the landing zone, the process is fast, ensuring smooth backup and recovery operations at high speeds. However, the process becomes slower for long-term backups moved to the retention zone due to fragmentation. So, if the data is older than a few days, the speed may be limited, especially for non-deduplicated data in the landing zone."
"The solution easily integrates with the backup targets, such as Veeam."
"The most valuable features are the deduplication and compression capabilities."
"The deduplication feature in this product is amazing."
"The initial setup process is simple."
"The hardware is strong and all the equipment has a good infrastructure. Personally, I think it's the best storage product in HPE for small to medium-sized businesses."
"The initial setup is simple."
"The product's most valuable feature is stability."
"The solution's most valuable feature is its catalyst mode, along with better performance, backup, and recovery."
"It is very easy to implement."

Cons

"I would like for them to develop direct cloud integration with a third-party cloud. Direct integration with AWS and other cloud providers."
"The product's documentation can be made more precise."
"When speaking about a scale-out, you want to have better equipment. You cannot just add a disc to the foreign equipment. You have to buy another one and put it together, like parallel."
"The tool reduces storage footprint. However, clients are now storing data for longer durations with increasing requirements to retain backups for longer periods, particularly as a defense against ransomware attacks. As a result, the retention zone with duplicated data is experiencing more demand, leading to space constraints. This necessitates using higher-end, more expensive models to address the issue."
"The solution could improve by switching to a flash-type solution rather than the spinning drives that they currently use. However, we have not had any failure with the spinning drives. The flash-type drives are more up-to-date and are something that is in their roadmap."
"The one place where we are sometimes losing the opportunity with ExaGrid is that a few customers still require a fiber channel connectivity, which is not always possible."
"One item I wanted to see is SSD drives as a cache, and that was, for a time, still lacking in StoreOnce, however, they have done it now. It's not available yet, however, it will be shortly."
"Agnostic backups."
"I would like to see better integration with Veeam software."
"Cloud integration needs to be simplified."
"The product could be improved with better support for data protection."
"The user interface of HPE StoreOnce is an area of concern where improvements are required."
"They could provide more options for storage capacity."
"We archive our backups on tape, so I feel like if we could somehow plug our tape drive directly into the StoreOnce device and set it up to where it would archive based on, if some kind of rules based engine or what have you, that would really be an improvement for us."

Pricing and Cost Advice

"My company had to pay 1,60,000 EUR for the system we use, and the payment was made just once for the system and five years of full support."
"I rate ExaGrid EX Series' pricing eight to nine out of ten."
"The current agreement has 21 terabytes of free space and it cost approximately $35,000."
"The previous solutions I have used both included the Backup Software and the Appliance making it hard to compare to this solution. However, overall the solution is reasonably priced for the features you receive. ExaGrid EX Series is priced better than HP, Dell, and possibly Commvault which I have compared in the past."
"In comparison to other solutions, it's affordable. They're all too expensive."
"The product's pricing is medium."
"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."
"The solution is pretty expensive."
"The product is not expensive. It is available at a good price."
"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."
"With the same capacity of Data Domain and ExaGrid, which is 80 terabytes, HPE is the cheapest one."
"There are costs for additional storage and space."
