Room For Improvement

Dell SC Series needs improved user-friendliness, technical support, integration, scalability, and features like compression, automation, and cloud compatibility.
Pure FlashArray X requires cost-effective improvements in UI, integration, cloud features, multitenancy, analytics, backup, AI, and scalability.
Dell PowerStore, which supports NVMe over TCP, is different and not very affordable.
In the future, I want any box that comes on-premises to have the provision to integrate with cloud storage.
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

Enterprise buyers see Pure FlashArray X NVMe as a justified premium investment due to performance and comprehensive licensing.
Sometimes Dell offers better performance for less money.
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 SC Series provides performance, auto-tiering, and replication with ease of management, scalability, high availability, and strong support.
Pure FlashArray X NVMe offers exceptional performance, reliability, scalability, and seamless VMware integration, enhancing workload efficiency and user experience.
The storage also lowered the response time of disks across the entire farm, making it a great product for operational efficiency.
I can mix and match the drives, using older mechanical devices and the latest SFP drives in a single solution with different enclosures.
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.

Featured Reviews

RafaelGamaluis - PeerSpot reviewer
User interface offers clarity and detailed information while technical support consistently delivers
The best features of Dell SC Series are stability and replication. The replication solution is excellent, and they have a solution named Live Migration. It is a robust platform. The interface and the GUI (graphical user interface) for administrating the Compellent are exceptional, with abundant information that is very clear. The management capabilities are excellent, and the stability of our storage hardware is remarkable.
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.
