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.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"Both the pricing and the performance are excellent."
"The most valuable features of ExaGrid EX are the Veeam features and Landing Zone."
"Backup and restore processes are much shorter now, and we don't need forklift upgrades every three to four years."
"I find ExaGrid EX to be a useful solution for customers looking for a budget-friendly product."
"I would highly recommend this product."
"Deduplication and compression are in a good ratio. It supports the HPE Catalyst protocol, which is much faster than NFS and other protocols. We use CommVault and Veeam, and these two solutions support the Catalyst protocol very well and are integrated at high speed. It is faster than normal access."
"The size of the backup data is very small, which is one of the features that we really like."
"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."
"With 3PAR and with StoreOnce, we kind of have an end to end solution for the customer."
"For anyone who is looking for a long-term archive, as well as a backup solution, this is the ideal product."
"The solution saves a lot of storage capacity."
"VTL with deduplication because with deduplication, you can have spare storage space."
 

Cons

"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."
"The solution’s web access should be improved."
"I would like to see free disk space."
"We are looking for Federated VTLs just like Federated Catalyst Store. Currently, VTLs can only be created on individual service sets and cannot be used to share the resources of other nodes."
"We selected this as a method to improve and better scale our backup deduplication, but it turned out StoreOnce introduced enough inconsistencies and incompatibilities, we actually went back to Commvault’s native deduplication."
"The solution's pricing could be improved."
"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."
"We wanted to restore the files we backed up, and on three occasions we were not able to, and this got us in a lot of trouble, so I don't think I will take this risk again. Use something else."
"It's not big, but it could be smaller and take up less space in the data center."
"We have lost some market due to the minimum capacity now being 80 terabytes."
"The product could be improved with better support for data protection."
 

Pricing and Cost Advice

"I rate ExaGrid EX ten out of ten for pricing."
"The renewal fee is approximately $3,500 to $3.750 for a 60 terabyte device."
"The solution's cost is above average."
"The price puts me off. It's definitely on the high side."
"I rate the platform's pricing a seven out of ten."
"With the same capacity of Data Domain and ExaGrid, which is 80 terabytes, HPE is the cheapest one."
"The licensing schemes could improve in HPE StoreOnce and the price is high. They should reduce the price."
"I rate the product's pricing a seven out of ten."
"The price of the product is reasonable."
"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."
