Sentiment score
5.1
Dell PowerVault drastically cuts storage costs for disaster recovery, enhancing financial benefits and competitive pricing, earning high user ratings.
If you purchase storage with 300 terabytes, you can easily achieve one petabyte of effective capacity.
It's been trouble-free the entire time, with very high performance, as it has been designed and built properly.
We have seen a return on our investment in Dell PowerStore; definitely our cost per terabyte has been very good compared to some of the other vendors that we would have been using previously, and our performance benchmarks have exceeded what we were expecting.

Dell PowerVault's customer service is highly rated for responsiveness, knowledge, and effective problem-solving, despite some logistical issues.
If necessary, they will search for a specialist within their Dell network who we can approach with our questions.
I would rate the technical support of Dell PowerStore between nine and ten out of ten.
They're responsive, knowledgeable, and have a quick turnaround.
Supporting Dell PowerVault is very easy.
The technical support for Dell PowerVault is pretty good and they usually get back to us in a couple of hours with a technical engineer.
 

Scalability Issues

7.1
Dell PowerStore offers scalable, flexible architecture, supporting diverse business needs through easy expansion and integration of multiple appliances.
Sentiment score

The solution's scalability is a ten out of ten.
The customer likely exceeds 20,000 users globally.
You can create as many tools as needed, providing scalability based on the use case.
I don't face any issues with security with Dell PowerVault.
The scalability is present but it is a bit complex to scale to the desired level.
 

Stability Issues

Sentiment score
7.6
Dell PowerStore is generally reliable, though update-related bugs can cause minor concerns among users despite consistent stability.
Sentiment score
7.0
Dell PowerVault is praised for stability and ease, though larger setups may need dual units for active-active configurations.
When I removed all the cables, it failed over within five minutes.
There are no bugs or glitches and it doesn't crash or freeze.
I would rate the stability of Dell PowerStore as ten out of ten.
Dell PowerVault has been stable.
 

Room For Improvement

Dell PowerStore needs improved integration, features, and support, focusing on UI, stability, pricing, and cybersecurity enhancements.
Dell PowerVault requires UI improvements, broader integration, better pricing, enhanced features, and greater customer outreach to remain competitive.
If you want to delve into where your I/Os are going, the reporting might need more in-depth information to make informed decisions.
In my organization, we have had to go through two weeks with no replication, which is not very handy for our production environment.
Something needs to be done with the caching to ensure that if some issue occurs, there needs to be an ability to disable caching during maintenance to make it static, safe, and good.
It would be beneficial for Dell to enhance outreach to new customers directly to prevent resellers from scaring them away with higher pricing.
There is room for improvement with Dell PowerVault as we did have some promises about dedupe and compression that did not turn out as promised.
I think expandability could be improved for Dell PowerVault.
 

Setup Cost

Dell PowerStore offers strong value with competitive pricing, straightforward licensing, and favorable price-to-performance compared to other NVMe options.
Dell PowerVault pricing is viewed as competitive by some, but higher costs and licensing fees concern other users.
Likely the cost is $400,000 whereas IBM may be $250,000.
Based on my experience, the cost of Dell PowerStore for around 500 GB of capacity is very competitive compared to any other platform in the market.
There's no need to pay for a license; it's all-inclusive.
I don't think it's terribly priced, but Pure Storage is cheaper.
 

Valuable Features

Dell PowerStore provides seamless management, impressive performance, intelligent optimization, and strong cybersecurity with ease of deployment and scalability.
Dell PowerVault is praised for reliability, scalability, ease of use, cost-effective storage, and exceptional customer support.
The solution promotes data reduction, often meeting the compression ratio.
The PowerStore's compression ratio is even higher than the Unity system.
The deduplication part of the solution is valuable since, as a user, you get more space for less money.
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.
It has been pretty stable.

Eoin O’Brien - PeerSpot reviewer
Improves cost efficiency and significantly while boosting workload performance
We have realized several benefits from using Dell PowerStore; we migrated to the current Dell PowerStore models from tiered storage, and now we're using all flash. The dedupe and compression has been a big benefit for us versus the old storage that it was running, and we've seen the performance of all flash for our storage services. My company finds particular features within Dell PowerStore valuable, primarily the cost benefits for the performance that we get out of the platform. We've definitely seen the benefit on that side of it, including the cost per terabyte, and the support from Dell has been excellent as well. We haven't had any issues with it, so it's been very reliable as a platform for us. The performance metrics I use to measure success with Dell PowerStore are all IOPS and throughput. We are not using it with AI workloads on Dell PowerStore, so it's primarily just customers running IaaS, however, it is important that it's reliable and performs well, and we get that from Dell PowerStore. Dell PowerStore has supported growth and operational success for my business; a key driver at the moment is consolidation, and the dedupe and compression ratios allow us to standardize on a single platform. This has helped improve our operational metrics and overall operations, as we now have only one vendor to support and one set of storage arrays to manage. We have a very clear path into support and escalation if there is an issue, and we are not dealing with multiple vendors.
RichardLynch - PeerSpot reviewer
Administrative ease and dependable support consistently enhance our operations
I would say my favorite features of Dell PowerVault are that it's pretty easy to use. It has been pretty stable. Firmware updates have been pretty easy to install and updates are pretty easy to do. Replacing a bad drive is fairly simple. It is just fairly easy to administer it.
