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.

A virtual deduplication backup appliance that protects physical and virtual data across remote sites, the datacenter and cloud deployments
Given its ease of use and management, I believe there are no specific caveats that users need to be aware of during the setup of DXRIS for backups. The process was straightforward, and I did not encounter any challenges or issues. As for a rating on a scale of one to ten, with one being the worst and ten being the best, I would rate the Quantum DXI Series a nine. My deduction is primarily influenced by personal preferences, particularly regarding the user interface and it is a highly commendable system, I would rate it a solid nine out of ten.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"It has very simple architecture compared to the old HP VLS and also provides ease of management and is easy to configure."
"The new solution is safe, efficient and cost effective."
"Backups are much quicker now; previously, it took 15-16 hours every day, and now it takes 3-4 hours maximum."
"The initial setup is simple."
"From a centralized system, I can manage the interface, the backup policies, and the status of the database."
"I like the tool’s deduplication feature. We get a ratio of 9:1 for deduplication. The product is also Linux based. Last year, our organization faced some virus attacks. However, the backup was safe because of the product being a Linux version. HPE StoreOnce is a secure product."
"We have saved time as less is spent on tape handling, and there are fewer hardware issues than with a tape."
"It's cost effective, technologically advanced, and very scalable."
"While the challenges posed by the difficulties were significant, they prompted the replacement of problematic components, resulting in the resolution of issues. Importantly, there were no substantial ongoing concerns. Regarding the overall performance, it has been consistently excellent."
"I am impressed with the tool's technical alliance with Veeam and Veritas."
 

Cons

"Segmentation was one of the requirements. The HP team promised us that it is possible, but it wasn't available."
"In the beginning, we had a lot of problems with bad firmware."
"HPE StoreOnce could improve the capacity support."
"With the older firmware we did have problems with the B6200 crashing with kernel problems, though this has now been addressed with the firmware updates."
"Pricing could be reduced"
"We had some growing pains, which was due to our internal issues."
"We selected this as a method to improve and better scale our backup deduplication, but it turned out StoreOnce introduced enough inconsistencies and incompatibilities, we actually went back to Commvault’s native deduplication."
"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."
"Perhaps the most notable area for enhancement lies in the web interface for management. The current limitations in LDAP editing capabilities are not addressed in the UI, and I haven't observed any recent updates. It's possible that the new version of the DXI service incorporates improvements in the GUI, but I cannot confirm. While there is room for improvement in the current GUI, it remains a relatively minor issue. Overall, the system is comprehensive, covering aspects such as reports on latency and networking, leaving little room for additional enhancements in those areas."
"The product needs to improve performance while scaling out. It also needs to improve stability."
 

Pricing and Cost Advice

"The product's pricing is medium."
"The cost of HPE StoreOnce is very expensive."
"The solution's cost is above average."
"The price of the product is reasonable."
"The product is not expensive. It is available at a good price."
"We have got a perpetual license, and we have access to all the features. If you are using cloud banks, you can store the internal data in HPE Cloud if needed. You can offload the data to the HPE Cloud. It is a licensed product. We have got around 10 TB of cloud bank storage with a one-time payment. We specifically took 10 TB for very critical offsite backups. We can also increase it in blocks if needed."
"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."
"I do not oversee this aspect, as pricing is contingent on factors such as volume, technical specifications, and the desired features. Consequently, I lack information on the pricing details and structure."
