Has handled backup storage needs reliably and supports seamless upgrades

IT Manager at Regin Dalarna

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.

Object storage has reduced costs and improves data protection for web application workloads

Cloudian HyperStore can be improved by making upgrades easier. Currently, I see that upgrades are very complicated, and most of the time I require Cloudian support whenever I want to upgrade. I think Cloudian has the opportunity to improve in self-service capabilities. If they make upgrades less vendor-dependent, that would be beneficial. I would also like to add that more automation APIs would be valuable. If more APIs were available for S3 compatible tasks, that would be great. I rate the product eight because if they make updates easier, make firmware upgrades easier, make compaction available on CMC instead of requiring scripts, make node cleanup straightforward, make forecasting simple, make capacity planning easy, and provide self-healing opportunities, I believe the rating would be a ten.

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.
