Comparison Buyer's Guide

Executive Summary

Review summaries and opinions

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

ROI

Sentiment score
4.9
Dell PowerVault provides cost-effective storage, offering stability and reliability, especially beneficial for entry-level and budget-conscious users.
Sentiment score
7.2
HPE StoreOnce enhances cost efficiency, speeds restores, and offers scalability, leading to generally high user satisfaction despite varied ROI.
This represents money saved and time saved, because one person has been able to store, view, modify, analyze, stop, and work properly on the administration of their own equipment and the entire storage farm that is under a single console.
Since we already have a very simple environment and a quite resource-optimized environment, I think the major return on investment with Dell PowerVault was above all being on a super stable, reliable platform that gives us the confidence to continue growing using the same platform.
IT Team Leader Latam at MC Bauchemie
I believe Dell PowerVault is the best option on the market at the moment, especially for entry-level and budget solutions.
System Engineer at a outsourcing company with 11-50 employees
If we request the price for StoreOnce as a standalone product, it tends to be higher than when it is included in a larger solution where we can receive better discounts.

Sr. Sales Consultant at Teccle Group
It is a system that was chosen specifically for this capability, allowing extension as needed and providing scalability on demand.

This was especially important given the choice to store video that is extremely critical both from a general point of view and from a legal point of view, where data must be kept and secured.

It is stable, performance is acceptable, and has good integration with backup, with interfaces like Fibre Channel and SMB to expose to the client.

Room For Improvement

Dell PowerVault needs improvements in responsiveness, integration, deduplication, pricing, support, cache capacity, and management for complex environments.
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.
Associate Vice President - Technical Services Group (TSG) at HGS
Only when environments become more complex, especially in the enterprise area, does Dell PowerVault struggle in the software area, including centralized management.
Sr. Sales Consultant at Teccle Group
There are two aspects to consider: replication, meaning replicating data from one site to another concerning Dell PowerVault, and another very important area where significant improvement is needed—everything related to expansion rules.
Moe Infrastructure Data Center at a transportation company with 10,001+ employees
It is well-positioned on the radar, with a mature and stable solution.
Infrastructure Manager at a paper AND forest products with 10,001+ employees
The benefits of StoreOnce, which we discussed, include its compression capabilities with a ratio of 1 to 10.
HPE Product Manager at a tech services company with 51-200 employees
While the solution does everything expected, it would be beneficial if AI could be integrated for optimization and monitoring.
Technical Director of Managed IT Division at base2
 

Setup Cost

Dell PowerVault is an affordable, competitive storage solution, though some users find it costly compared to alternatives.
HPE StoreOnce setup is costly initially, but offers competitive, feature-rich pricing with capacity-based licensing and bundled support.
I don't think it's terribly priced, but Pure Storage is cheaper.
Architect at a energy/utilities company with 10,001+ employees
Dell PowerVault is fairly within the budget for our operations and for our client's operations.
Senior Enterprise Systems Engineer at Fonicom
If you use a PowerVault with SSD hard disk, it begins to be rather expensive.
System Technician at Lidingö stad
The solution is quite expensive, possibly rated around seven and a half on a scale of one to ten.
Technical Director of Managed IT Division at base2
 

Valuable Features

Dell PowerVault offers budget-friendly, scalable, and reliable storage with seamless integration, ideal for video surveillance and enterprise virtualization.
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.
Associate Vice President - Technical Services Group (TSG) at HGS
What differentiates Dell PowerVault from other storage solutions is the performance combined with the ability to meet significant bandwidth consumption needs.
Moe Infrastructure Data Center at a transportation company with 10,001+ employees
This mainly gives us time to react and provides us with peace of mind that if something happens, we can be up and running within a span of approximately 30 minutes.
Senior Enterprise Systems Engineer at Fonicom
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.
HPE Product Manager at a tech services company with 51-200 employees
The most effective features for data deduplication are maximizing storage capacity and minimizing expenditure.
Technical Director of Managed IT Division at base2
The recovery is important.

Featured Reviews

Storage has supported long-term CCTV archiving and improves on-premises application performance
I think it would be good regarding how Dell PowerVault could improve to have, in addition to the excellent support service that exists, some training courses, forums, and a training school for using these tools. Many people specialize only in this kind of equipment, and others have no idea how to configure them or how they work and always end up depending on people who have spent a long time working with these systems and know how to handle them more because of experience than because of information that can be easily obtained about using this equipment. Everything regarding additional aspects that could be improved in Dell PowerVault has already been mentioned.

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.
