Sentiment score
6.9
Nutanix Unified Storage boosts ROI by reducing costs, enhancing uptime, scalability, and efficiency, while improving data management and productivity.
If AWS improves support and cost management, there would be fewer reasons for users to consider other cloud platforms.
As it is Amazon S3 Glacier, it is used only for archival purposes, so it is comparatively okay to use it, and we can save money compared to the standard which is high.

Featured Reviews

ArunDhwaj - PeerSpot reviewer
Versatile data storage improves security and supports increasing data volumes
Amazon S3 Glacier offers robust security features and practically infinite storage, where we can store all kinds of media swiftly. It supports various data types, including semi-structured and raw formats. These features facilitate log management and data dumping since the service is versatile enough to handle large volumes of data and provide necessary security.
Amarnath Charugundla - PeerSpot reviewer
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.
