Sales 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.

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.

Pros

"The most valuable features of ExaGrid EX are the Veeam features and Landing Zone."
"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."
"Backup and restore processes are much shorter now, and we don't need forklift upgrades every three to four years."
"HPE StoreOnce has high performance."
"The stability has been rock solid."
"The solution's licensing policy is more practical and not confusing."
"Due to high speed and multiple simultaneous backup sessions our backup window is reduced remarkably, data throughputs are mentioned as follows: Up to 100 TB/hr of backup performance with StoreOnce Catalyst, up to 40 TB/hr of native backup performance, up to 40 TB/hr of restore performance."
"The initial setup is simple."
"If you want a reliable and reasonably-priced product, I would recommend it."
"Support is the main thing; if we have any issue, it’s easy for us to track or investigate it, because we don’t have different solutions from different vendors."
"I recommend this product because of the easy integration with Veeam and other backup products."
 

Cons

"The solution’s web access should be improved."
"I would like to see free disk space."
"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."
"StoreOnce doesn’t work for our class of data, which is small, and needs to include more genomic and medical research as test cases."
"A feature that is missing, compared to the competition, is the ability to globally duplicate all systems."

"That can be difficult and frustrating at times, but over ten years working with them, I would say today it's probably a little better than when I first started."
"StoreOnce software is sometimes unstable."
"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."
"This product would be improved with the inclusion of more features to security or WORM."
"If you don't know all the parts and pieces, then you've got a failed implementation."
