For the stability of HPE StoreOnce, based on customer feedback, I rate it highly as one of the most stable products in the backup and archiving line.
 

Room For Improvement

Dell PowerVault needs better features, integration, scalability, and pricing, addressing user concerns about costs and outdated technology.
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.
If they reintroduce models with 48 terabytes, it would serve small and medium customers better since not everyone requires to back up large data sizes.
It is well-positioned on the radar, with a mature and stable solution.
While the solution does everything expected, it would be beneficial if AI could be integrated for optimization and monitoring.
 

Setup Cost

Dell PowerVault setup costs around £30k, with competitive pricing, though some users find it expensive compared to alternatives.
HPE StoreOnce setup is costly initially, but offers competitive, feature-rich pricing with capacity-based licensing and bundled support.
The solution is quite expensive, possibly rated around seven and a half on a scale of one to ten.
 

Valuable Features

Dell PowerVault offers scalable, reliable, and cost-effective SAN storage with user-friendly management and diverse features for various enterprise needs.
HPE StoreOnce provides efficient data management through high-performance deduplication, scalability, and seamless integration for optimal backup and storage solutions.
We've even used PowerVault series that we intended to use for five years for almost eight years, and it was still working fine, providing good ROI compared to any other brand.
The stability of Dell PowerVault is good; I would rate it a nine.
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.
The most effective features for data deduplication are maximizing storage capacity and minimizing expenditure.
The recovery is important.

Consistent cost reduction and ease of deployment with storage solution
Dell PowerVault acts as an entry storage for a small organization; I've been using it in my organization. Dell PowerVault functions as SAN storage and iSCSI storage. Per workload capacity, the deployment and migration time is dependent on various factors. Dell PowerVault has strong features; we can work on it as a SAN storage, and if we are connecting with fiber, 16 gig or 22 gig, and as the iSCSI also. Dell PowerVault is a small SAN storage, and I recommend it for small organizations. If the customer does not have enough budget, and already has small capacity with not difficult workload, this is an entry-level storage solution, and for Dell PowerVault, I'm satisfied. I rate Dell PowerVault a nine out of ten.
