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."
"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."
"Its catalyst store and deduplication are valuable as it saves disc space."
"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 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."
"The most valuable feature of the solution is its UI. The product's UI makes it easy for users to configure the tool."
"As far as once we've implemented the StoreOnce, it's achieved what we thought it would do and then some."
"The new solution is safe, efficient and cost effective."
"The initial setup is one of the most user-friendly B2B user solutions. It's good, it's easy. Deployment usually takes less than one day. You only need one person for deployment and maintenance."
"It is at the top of its class, in my experience."
 

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."
"HPE StoreOnce needs to provide a SaaS solution by offering high-density disks."
"Reporting needs to be worked on."
"The initial setup is quite complex and difficult."
"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."
"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."
"If you don't know all the parts and pieces, then you've got a failed implementation."
"Segmentation was one of the requirements. The HP team promised us that it is possible, but it wasn't available."
"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."
 

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."
"I rate the product's pricing a seven out of ten."
"The solution is pretty expensive."
"The solution's cost is above average."
"The licensing schemes could improve in HPE StoreOnce and the price is high. They should reduce the price."
"The licensing costs is capacity-based and come bundled with support."
"The product is not expensive. It is available at a good price."
"With the same capacity of Data Domain and ExaGrid, which is 80 terabytes, HPE is the cheapest one."
"I rate the platform's pricing a seven out of ten."
