Featured Reviews

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.

Pros

"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."
"Both the pricing and the performance are excellent."
"The most valuable features of ExaGrid EX are the Veeam features and Landing Zone."

"With 3PAR and with StoreOnce, we kind of have an end to end solution for the customer."
"The initial setup of HPE StoreOnce is simple."
"HPE backup systems are very good products, easy to manage, with very good performance, a lot of ongoing new development, and good integration with many backup or storage products."
"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."
