Gourab Das - PeerSpot reviewer
Senior Manager at a financial services firm with 1,001-5,000 employees
Virtualization has transformed our data center and delivers consistent uptime with seamless maintenance
The most valuable feature VMware ESXi offers me is the user interface and the ease of handling operations without downtime, which is the biggest advantage, particularly with capabilities for live patching, and VCF 9 in patching areas; the bundled licensing provided simplifies management as I can utilize resources based on my needs without worrying too much about individual licenses. The zero-downtime patching is the feature that makes the biggest difference in my day-to-day operations, as well as managing hosts with an n+1 configuration, using a buffer host to streamline maintenance within a cluster of hosts. The vMotion feature is another important aspect, as we opt for auto vMotion to optimize resources within the cluster, enabling the underlying VMs to be moved seamlessly from one host to another based on utilization without impacting applications. VMware ESXi has positively impacted our organization significantly in terms of operations and cost optimization, as we optimized our environment under a per-core license agreement, achieving around 30 to 40% cost-effectiveness and maintaining almost 99.99% uptime across our environment, where VMware ESXi is run on about 85% of our setup. Improvements in operations were made possible through visibility provided by VMware ESXi into hardware enhancements, such as virtual storage platforms with vSAN, which we incorporated into our environment supported by VMware ESXi 9 to enable effective live patching without impacting operations, and we regularly utilize RV tool reports to track actual utilization and optimize resources, reducing our footprint from 100 VMs on 100 hosts to 47 hosts, yielding substantial financial benefits thanks to the support from our VMware ESXi TAM.
