Ajai Jayakumar

Has supported secure file sharing and data automation with minimal setup effort

The encryption feature in Microsoft Azure Block Storage is very good, and the security is excellent. It is easy to map the storage to the virtual servers and user desktops, which is also very beneficial. I can perform automations on the data, such as moving hot data and cold data, and I can select storage based on performance. The security provided by Microsoft around Microsoft Azure Block Storage is a very good function. The replication feature in Microsoft Azure Block Storage is a very good function. The analytic capabilities of Microsoft Azure Block Storage can help optimize resources. I usually work with a third-party tool; our data analytics team uses some custom-made tools for analytics data and dashboards, so we do not use the Microsoft dashboard; we are using a third-party dashboard. It is very easy to manage Microsoft Azure Block Storage. If you have good knowledge of it, it is very easy to manage. Microsoft Azure Block Storage service is a very good, 100% reliable service. It is highly scalable, and performance-wise and reliability-wise, it does not go down. It provides 99.9% uptime without downtime, so it is a very good feature. The backup and restoration efficiency of Microsoft Azure Block Storage is good.

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.
