Daan Lieshout - PeerSpot reviewer
With great features like deduplication and landing zone, the tool also provides stability and scalability
Speed-wise, ExaGrid is much faster than the other solutions in the market. When you choose between or from several different manufacturers, you need to understand a little bit about how the product exactly works and why its speed can be so high while being able to compare it to other solutions, allowing you to know of the backup window if you ever need it. You have to understand how it works and the product's preferences, even though the price may be slightly higher. Learning about the solution is not at all a problem, but when you open a console, you see so many things, and in the beginning you don't understand it all. Later on, it becomes more usable when you start understanding it. In general, ExaGrid provides you with a lot more information than any other system in the market. It is difficult to say what is additionally required in the solution because, presently, it has a lot of things like immutability, anti-hacking, and retention. The solution does put efforts towards improvement. The product's interface provides you with a proper overview of the deduplication rate and the status of how many storage systems you are left with through a visual screen, which is more than enough. When you go deeper, you can access all the enhanced consoles. The product can easily be integrated with third-party products because ExaGrid has all its best practice documents for integrating it with many other products. I rate the overall product a nine out of ten.

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 solution easily integrates with the backup targets, such as Veeam."
"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 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."
"One of the main features is the landing zone, it is a particular space where the information is not duplicated."
"The most valuable features of the solution are deduplication and landing zone."
"It's easy to backup data, manage. A"
"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."
"We also really benefit from the GUI capabilities."
"The scalability is very good."
"Quick recovery."
"The most valuable feature of the solution is that the tool provides good value for somebody who needs an affordable and reliable storage solution."
"The implementation is not that complex for someone who has experience."
"I think the most valuable feature is the catalyst technology, which is in the StoreOnce appliance."
 

Cons

"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."
"I would like for them to develop direct cloud integration with a third-party cloud. Direct integration with AWS and other cloud providers."
"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 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."
"Hardware maintenance involves some downtime for backup destination storage which can be a problem for some."
"I would like to see better integration with Veeam software."
"While StoreOnce has many features, it needs to focus on integrating with third-party backup software solutions."
"This product would be improved with the inclusion of more features to security or WORM."
"The solution should continue to refine its integration capabilities. I also see they are starting to use cloud integration as well, which is good, but they should do more to integrate with it."
"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."
"In terms of areas for improvement, I believe HPE StoreOnce could learn from competitors like Dell's Data Domain and ExtraHop in refining its architecture."
"The solution's technical support should be faster."
 

Pricing and Cost Advice

"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 current agreement has 21 terabytes of free space and it cost approximately $35,000."
"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 price of the product is reasonable."
"Price-wise, it comes with a high price tag when compared to other products."
"The product's pricing is medium."
"The product is not expensive. It is available at a good price."
"The licensing schemes could improve in HPE StoreOnce and the price is high. They should reduce the price."
"I would rate it around two or three because, compared to others, it tends to be higher priced."
"I think the product is competitive in terms of pricing. Other products like the one from Dell are costlier compared to the tool."
"The licensing costs is capacity-based and come bundled with support."
