Featured Reviews

Jaehoon Oh - PeerSpot reviewer
Chief Technology Officer at Lambda256
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
Lead Consultant - Cloud & Infrastructure Services at Infosys
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.
Amarnath Charugundla - PeerSpot reviewer
System Engineer at Tata Consultancy
Unified management and cost-effectiveness lead to positive experiences and future savings
Improvement is necessary wherein the memory or storage should not breach 90%, because if breached, it becomes unmanageable. We have to set alerts or CPU triggering for 95% for the first warning. Other activities on nodes or file systems should be properly maintained. We must monitor the dashboard for P1, P2 alerts in the Nutanix Unified Storage (NUS) file share system including SMB, NFS, objects, and blocks. Attention should be maintained for any alerts such as CPU, memory, and RAM alerts, as exceeding these creates issues within teams. If triggered to 95% and forgotten, it crosses the SLA breach, causing disturbances to application, web, and platform teams. Continuous monitoring on the Nutanix dashboard is essential. Even a highly experienced person in Nutanix Unified Storage (NUS) cannot provide a 10 rating out of 10 because it is a vast system. I would rate it eight from my perspective.
