Room For Improvement

Pure FlashArray X requires cost-effective improvements in UI, integration, cloud features, multitenancy, analytics, backup, AI, and scalability.
Dell PowerMax needs improvements in deduplication, UI, cloud integration, cost efficiency, AI, security, and system setup.
Dell Unity XT needs improved deduplication, compression, integration features, support, affordability, and simplified management for enhanced user satisfaction.
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.
Compared to competitors such as NetApp, which integrates with public cloud hyperscalers (GCP, Azure, AWS), Dell PowerMax lacks in this aspect.
Dell can assist by providing plug-and-play integrated templates that allow customers to drag, drop, modify, and connect with any target system for generating snapshots without logging into the storage directly.
Dell PowerMax NVMe is very reliable storage and cannot experience downtime.
In the future, if Dell storages include this option, especially for Unity, it would help us target SME or medium enterprises for quicker closures and support the sales team.
I believe if Dell can integrate AI to predict potential failures, especially in hardware like hard disks, that would be very useful for proper maintenance.
The pricing is a bit higher than expected.
 

Setup Cost

Enterprise buyers see Pure FlashArray X NVMe as a justified premium investment due to performance and comprehensive licensing.
Dell PowerMax is costly yet competitive, appreciated for total ownership value, offering various pricing models and potential savings.
Dell Unity XT is competitively priced, offering robust features and support, suitable for mid-range budgets despite transparency concerns.
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.
The higher cost compared to other vendors is justified by additional features, vendor-managed upgrades, and superior support services.
It is the best choice for large projects in terms of price and features compared to midrange solutions.
The price is starting from $500,000.
It is priced at around or under $50,000.
The cost is not cheap nor expensive.
Commercially, Dell Unity XT is viable and competitively priced.

Jaehoon Oh - PeerSpot reviewer
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.
MayankChauhan - PeerSpot reviewer
Delivers essential support and performance for intensive operations in real-time environments
Our infrastructure is spread across the private as well as a public cloud. Our requirement was that the IOPS latency should not be more than one millisecond. If anything goes beyond one millisecond, it's a problem for us. We wanted a system that could handle the transactions and meet our latency requirements. There are performance benefits for sure. The amount of deduplication and compression offered by Dell PowerMax is quite good, especially with databases. Dell PowerMax delivers optimum performance and reliable support, integral for handling failures and ensuring operational continuity. The performance capacity optimization and support we receive from Dell are also valuable.
Syed Habib - PeerSpot reviewer
Efficient data replication and fast IOPS have improved operational performance
Dell and a partner jointly implemented this solution in Auvink. We installed the Flash, which makes our IO operations fast and efficient. Replication is available, allowing us to replicate data simultaneously from one site to another. All-flash technology and vTXT enhance speed, and the IOPS are faster. The cache's IOPS are much better. Snapshots provide a unique feature for testing and make management more comfortable and easy. The platform is multi-supported and certification is more convenient and easy to manage.

The PowerMax NVMe is the high-end storage fromDellEMC it can provide up to 10M IOPS, however, if you need less, you can go with the new Unity XT which is going to have NVMe as well. The new Unity XT is going to be ready for order in June 2019.

I have used all, EMC, and HPE 3Par, VNX, Unity, etc. All are OK. But for long term Flash Storage, I would take a look at Hitachi F Series. Best reliability hands down and they provide non-disruptive migrations, no server downtime, no scheduling with users, etc. NDM makes Hitachi a no brainer.
