AhmedEl-Tayeb - PeerSpot reviewer
Sales Manager at a tech consulting company with 201-500 employees
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.

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.

Quotes from Members

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

Pros

"Backup and restore processes are much shorter now, and we don't need forklift upgrades every three to four years."
"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."
"Recovery is important."
"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 interface is very user-friendly."
"It is at the top of its class, in my experience."
"The speed and deduplication ratio are two of the most valuable features of the solution."
"Because we're sensitive to the amount of storage our backups take, datafication is the most valuable feature for us."
"The ease of use is excellent and the price point is very competitive."
"This solution has allowed us to feel confident in that we have a mechanism for the full recovery of service, and not only our data."
 

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."
"HPE StoreOnce should come with a detailed installation guide."
"While the solution does everything expected, it would be beneficial if AI could be integrated for optimization and monitoring."
"The web interface, ease of use, and GUI all need to be improved."
"Maybe when we do restores for Veeam, the way it has to re-hydrate all the deduplicated data, if there's a way to speed that up that would be a good feature, some kind of algorithm or something."
"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."
"From a feature functionality perspective I think overall having some more mobility tied into it, having the ability to have applications that you can use on the go, that can give you kind of an overlay of the overall health and welfare of your data protection and data recovery strategy, being able to do simple things, like having run books."
"The initial setup is difficult for the normal user."
"When it comes to upgrading, it always goes block-wise. One block is 48 TB raw capacity. It would be good if they can include a smaller capacity for SMB customers. Currently, it is not possible to increase in a smaller capacity. You have to buy the exact same unit. It would be great if they can provide a smaller next block. There are around 20 hard disks, and it would be really helpful if we can add 10 hard disks initially and 10 hard disks later."
 

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 is pretty expensive."
"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."
"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."
"The product's pricing is medium."
"The product is not expensive. It is available at a good price."
"There are costs for additional storage and space."
