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.

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

"One of the main features is the landing zone, it is a particular space where the information is not duplicated."
"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."
"The most valuable features of the solution are deduplication and landing zone."
"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."
"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 solution easily integrates with the backup targets, such as Veeam."
"The interface is very user-friendly."
"I'm impressed with their support structure, call availability, understanding, flexibility in scheduling remote sessions, and accommodating customer timeframes."
"We also really benefit from the GUI capabilities."
"I think the most valuable feature is the catalyst technology, which is in the StoreOnce appliance."
"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."
"Recovery is important."
"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."
"The important feature is compression and duplication. It has a good compression ratio and is very stable."
 

Cons

"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."
"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."
"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."
"I would like for them to develop direct cloud integration with a third-party cloud. Direct integration with AWS and other cloud providers."
"The appliance doesn't have the global deduplication, it has StoreOnce deduplication. It does not deduplicate across the appliance, it will deduplicate in one particular store. With the global deduplication, I could store more data."
"Some high-level cybersecurity features could be achieved with some entities, and their integration could be built into the store."
"The setup phase is not so simple that an end user can plug and play to make it operational."
"The product could be improved with better support for data protection."
"Hardware maintenance involves some downtime for backup destination storage which can be a problem for some."
"It is difficult to solve issues with this solution remotely. I prefer to use the knowledge base platforms. The response time could improve."
"The solution's technical support should be faster."
"Its customer service could be faster."
 

Pricing and Cost Advice

"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 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."
"With the same capacity of Data Domain and ExaGrid, which is 80 terabytes, HPE is the cheapest one."
"The product's pricing is medium."
"The licensing schemes could improve in HPE StoreOnce and the price is high. They should reduce the price."
"The price puts me off. It's definitely on the high side."
"I rate the platform's pricing a seven out of ten."
"The licensing costs is capacity-based and come bundled with support."
"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 product is not expensive. It is available at a good price."
