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.
By opting for the gold subscription every three years, you get a free upgrade to the latest controller release.
If you wait more than seven years to buy another one, you get a return on your investment.

Room For Improvement

Dell PowerStore needs improved integration, features, and support, focusing on UI, stability, pricing, and cybersecurity enhancements.
Pure FlashArray X requires cost-effective improvements in UI, integration, cloud features, multitenancy, analytics, backup, AI, and scalability.
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.
We would appreciate a built-in transparent failover in the next release to eliminate the need for a separate metro cluster.
I'm eagerly anticipating the roadmap's promise of introducing multiple controllers, which could significantly boost scalability and resilience.
We mostly rely on long-term releases. We don't need the most up-to-date features, but we need a reliable environment.
 

Setup Cost

Dell PowerStore offers strong value with competitive pricing, straightforward licensing, and favorable price-to-performance compared to other NVMe options.
Enterprise buyers see Pure FlashArray X NVMe as a justified premium investment due to performance and comprehensive licensing.
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.
While the prices may be higher than those of other vendors, we see it as a market leader with benefits.
The support can be a bit pricey, but the solution is more cost-effective than anything else out there.
I would give it a nine out of ten in terms of costliness.
 

Valuable Features

Dell PowerStore provides seamless management, impressive performance, intelligent optimization, and strong cybersecurity with ease of deployment and scalability.
Pure FlashArray X NVMe offers exceptional performance, reliability, scalability, and seamless VMware integration, enhancing workload efficiency and user experience.
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.
Pure Storage has signature security technology, which cannot be deleted, even if you are an administrator.
The platform's robust features include excellent sustainability tracking, and a comprehensive dashboard offering insights into IOPS, bandwidth, performance, and virtual activities.
Its data compression feature is the best that we have ever seen.

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.

Supports efficient storage management through volume snapshots and offers reliable non-disruptive upgrades
I have no specific improvements to suggest for Pure FlashArray X NVMe at this time. The performance statistics could be enhanced. I can see the performance statistics in the Pure Storage console, but it does not show the performance by 4K byte unit. It displays IOPS and bandwidth, but IOPS is about real use, and I want to know how many IOPS are currently running in 4K byte units. I cannot see that IOPS because most storage systems report their performance by 4K byte unit. I want to see Pure Storage performance by 4K byte unit to compare with other storage or other internal NVMe SSD.
