Users seek improved interface, expandability, affordability, and integration for Dell PowerVault, highlighting scalability and feature deficiencies like deduplication.
Users seek improved deduplication, integration, interface, setup, support, storage, performance, pricing, and cloud features in HPE StoreOnce.
It would be beneficial for Dell to enhance outreach to new customers directly to prevent resellers from scaring them away with higher pricing.

Only when environments become more complex, especially in the enterprise area, does Dell PowerVault struggle in the software area, including centralized management.

Setup Cost

Featured Reviews

Erhan Parlaz - PeerSpot reviewer
Sr. Sales Consultant at Teccle Group
Reliable midmarket backups have supported disaster recovery while centralized management needs work
Areas where I feel Dell PowerVault could be improved include especially the enterprise area and multiple interfaces in other areas, for example, backup software solutions and their integration. Handling extensive storage management functions such as snapshots, replication, and provisioning with Dell PowerVault is very well suited for the midmarket or even smaller midmarket environments. Only when environments become more complex, especially in the enterprise area, does Dell PowerVault struggle in the software area, including centralized management. I would welcome it if Dell PowerVault were a bit easier to manage in centralized management via the GUI, as it was in the past, because at the moment mid-sized companies find it not so straightforward to clearly calculate things such as how and where to use something, especially in the snapshot area. There is still room for improvement due to the missing interfaces and also the flexibility.

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.
