AhmedEl-Tayeb

Product Manager at MCS

Has offered a cost-effective option with solid results but requires automation features for better efficiency

For ExaGrid EX, I would appreciate additional features such as backup and restore, automation processes, and automation software for backup and restore processes. I mention that some additional features may be provided by VMware or Dell as support for the hardware they are selling, but ExaGrid EX is more of a budget-friendly solution for customers who are in charge on a daily basis of the solution itself, dealing with manual tasks rather than automated tasks. I am not in a situation to provide an exact answer for what I would specifically improve in this regard.

Naguib Wasef

HPE Product Manager at a tech services company with 51-200 employees

Collaborate effectively with partners and benefit from robust data management capabilities

The functions of HPE StoreOnce that I find most valuable are its deduplication and replication options. These features save data and reduce the size of data significantly. If the actual size for backup data is 100 terabytes, using StoreOnce, it will be around less than 10% of the original size due to the 1 to 10 deduplication ratio. So, compression and replication are critical features I appreciate. Additionally, adaptive backup and restore capabilities of HPE StoreOnce are indeed very helpful functions. As I know from my technical team, the process is very easy for end users because the GUI and user experience with StoreOnce are straightforward. They can restore their backups at any time. An important feature of StoreOnce is that they can reserve an amount of storage capacity as protected capacity for a limited time, safeguarding their data against intrusion and other interactions. Based on feedback from customers, StoreOnce is regarded as a highly useful solution for backup. I am satisfied with the security aspects of HPE StoreOnce, but it's crucial for any company to maintain a multi-layer security approach. Starting with a firewall is essential for maintaining their environment. Additionally, security features on StoreOnce are useful. I believe that no company should rely solely on one layer of security; they should adopt a multi-layer security strategy that begins at the network level and extends to their internal solutions.

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

"I find ExaGrid EX to be a useful solution for customers looking for a budget-friendly product."

"Both the pricing and the performance are excellent."

"I find ExaGrid EX to be a useful solution for customers looking for a budget-friendly product."

"I think StoreOnce's deduplication technology is crucial for cost efficiency and faster recovery, especially for backup and data protection purposes."

"HPE StoreOnce has high performance."

"VTL with deduplication because with deduplication, you can have spare storage space."

"I'm impressed with their support structure, call availability, understanding, flexibility in scheduling remote sessions, and accommodating customer timeframes."

"Because we're sensitive to the amount of storage our backups take, datafication is the most valuable feature for us."

"For anyone who is looking for a long-term archive, as well as a backup solution, this is the ideal product."

"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."

More HPE StoreOnce pros

"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."

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

Cons

"I would like to see free disk space."

"The solution’s web access should be improved."

"ExaGrid EX is more of a budget-friendly solution for customers who are in charge on a daily basis of the solution itself, dealing with manual tasks rather than automated tasks."

"I would like to see free disk space."

"One of the drawbacks of this product is that you cannot add another disk array when you reach capacity."

"I'd like to see the following features added in: More detailed reporting, more granular reporting, and more features in the CLI."

"The dashboard needs more improvement."

"An improvement would be an improved deduplication algorithm."

"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."

"The initial setup is quite complex and difficult."

"The auto load balancing between VTL Libraries has been not as efficient as it should have been."

"The CIFS share service performance is really poor; it is a nightmare."

More HPE StoreOnce cons

"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."

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

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."

"The solution's cost is above average."

"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."

"I rate the product's pricing a seven out of ten."

"Price-wise, it comes with a high price tag when compared to other products."

"The product's pricing is medium."

"The price puts me off. It's definitely on the high side."

"I would rate it around two or three because, compared to others, it tends to be higher priced."

More HPE StoreOnce pricing and cost advice

"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."
