Improvements in data storage efficiency and customer support experience

ExaGrid EX Series and Veeam was easy to set up, and it worked seamlessly. It was very simple to use. We rarely needed to touch the ExaGrid boxes, except for upgrades. With the systems engineer from ExaGrid, and with our common knowledge of backup software, it was very easy to use. The performance was good, the interface was good, and the GUI was good. When ExaGrid introduced the air gapped feature, it was almost complete. Almost every hardware vendor has an air gapped feature, but they were significantly ahead of other vendors. The air gapped and immutable storage are very nice features. The price compared to other competitors was good with better features. It is not a cheap product, but compared to the features, it is a good competitor.

Expert Backup at a tech services company with 201-500 employees

A virtual deduplication backup appliance that protects physical and virtual data across remote sites, the datacenter and cloud deployments

Given its ease of use and management, I believe there are no specific caveats that users need to be aware of during the setup of DXRIS for backups. The process was straightforward, and I did not encounter any challenges or issues. As for a rating on a scale of one to ten, with one being the worst and ten being the best, I would rate the Quantum DXI Series a nine. My deduction is primarily influenced by personal preferences, particularly regarding the user interface and it is a highly commendable system, I would rate it a solid nine out of ten.

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."

"One of the main features is the landing zone, it is a particular space where the information is not duplicated."

"ExaGrid EX Series and Veeam was easy to set up, and it worked seamlessly."

"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 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 features of the solution are deduplication and landing zone."

"I am impressed with the tool's technical alliance with Veeam and Veritas."

"While the challenges posed by the difficulties were significant, they prompted the replacement of problematic components, resulting in the resolution of issues. Importantly, there were no substantial ongoing concerns. Regarding the overall performance, it has been consistently excellent."

Cons

"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 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 product's documentation can be made more precise."

"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."

"The product needs to improve performance while scaling out. It also needs to improve stability."

"Perhaps the most notable area for enhancement lies in the web interface for management. The current limitations in LDAP editing capabilities are not addressed in the UI, and I haven't observed any recent updates. It's possible that the new version of the DXI service incorporates improvements in the GUI, but I cannot confirm. While there is room for improvement in the current GUI, it remains a relatively minor issue. Overall, the system is comprehensive, covering aspects such as reports on latency and networking, leaving little room for additional enhancements in those areas."

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."

"In comparison to other solutions, it's affordable. They're all too expensive."

"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."

"The current agreement has 21 terabytes of free space and it cost approximately $35,000."

"I do not oversee this aspect, as pricing is contingent on factors such as volume, technical specifications, and the desired features. Consequently, I lack information on the pricing details and structure."
