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."
"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."
"The solution saves a lot of storage capacity."
"StoreOnce is a backup solution with Data Protector in DDD and streaming through offsite storage, and it works just fine."
"The deduplication feature is awesome; the storage space has been cut down by at least 50% and on some instances greater reduction has been achieved."
"After we implemented Catalyst with Data Protector, the recovery process time of one or two days was reduced to 30 minutes in most cases."
"The product has really improved the backup and restore for our infrastructure."
"The product’s data retention is very good."
"The stability of the solution is excellent."
"Nothing's perfect, but the speed we get from the system, the deduplication we get from the system, the replication, it all works as designed."
 

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."
"Segmentation was one of the requirements. The HP team promised us that it is possible, but it wasn't available."
"The dashboard needs more improvement."
"The initial installation and configuration into the network and the integration into the infrastructure needs some improvement, but it's not too difficult if you plan right."
"improvement? HPE StoreOnce has a limitation with respect to controllers. Other tools offer more than one controller. I feel that the high availability of the view controller should be redundant. The tool’s control and UI part should be improved and made more advanced. The feature that helps with the manual movement of tapes should also be improved."
"We didn't like anything about this product."
"This is an entry level model, even more disk space would be valuable."
"The one issue I have is the maintenance package – it's very expensive."
"Initial setup is done via ssh connection and not web based, and the web based management is a little less appealing visually than the previous incarnation."
 

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."
"I think the product is competitive in terms of pricing. Other products like the one from Dell are costlier compared to the tool."
"The solution is pretty expensive."
"The licensing schemes could improve in HPE StoreOnce and the price is high. They should reduce the price."
"There are costs for additional storage and space."
"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."
"The product is not expensive. It is available at a good price."
"The licensing costs is capacity-based and come bundled with support."
"Price-wise, it comes with a high price tag when compared to other products."
