Featured Reviews

MikaelHellström - PeerSpot reviewer
IT Manager at Regin Dalarna
Has handled backup storage needs reliably and supports seamless upgrades
In environments requiring high throughput and low latency, Pure Storage FlashBlade provides high throughput and normal latency, but we do not have any application that requires low latency right now, so the latency of three to five milliseconds is considered kind of high. Pure Storage FlashBlade's ability to integrate with enterprise applications is not important for us, as we only want to present an S3 bucket for our backup, which we have done, and it works very fast. We use the Purity software's data reduction techniques; we have a backup software that compresses everything before sending it to the S3 bucket, achieving a data reduction of 1.1 to one. I would recommend Pure Storage FlashBlade to other companies because it's a very fast and scalable solution for anyone who needs it. On a scale of 1-10, I rate this solution an 8.
MA
Manager, Technical Services at AXS
Offers seamless protocol integration for diverse solutions with flexible API communication
We recommend Dell ECS to customers looking for GeoDrive, archiving, long-term retention solutions, or S3 protocol. It is proposed to sectors like government, education, and banking. Overall, I would rate Dell ECS eight out of ten, as it has shown a lot of enhancement compared to previous solutions like Centera and Atmos.
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.
