Room For Improvement

Pure FlashArray X requires cost-effective improvements in UI, integration, cloud features, multitenancy, analytics, backup, AI, and scalability.
Dell SC Series needs improved user-friendliness, technical support, integration, scalability, and features like compression, automation, and cloud compatibility.
Users seek improved deduplication, integration, interface, setup, support, storage, performance, pricing, and cloud features in HPE StoreOnce.
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.

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.
For more quotes and insights, download the Dell SC Series report
It is well-positioned on the radar, with a mature and stable solution.
The benefits of StoreOnce, which we discussed, include its compression capabilities with a ratio of 1 to 10.
While the solution does everything expected, it would be beneficial if AI could be integrated for optimization and monitoring.

Featured Reviews

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.

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.
