Overall Satisfaction with VMware ESXi
We use ESXi 5.5 primarily for server virtualization. We also host a XenApp 7.8 farm in our production cluster. We have a production datacenter cluster, a cluster for our Dev/DR site and a single host site at a remote facility used to host a domain controller, ras server and print server. It addresses th problem of server sprawl and consolidates about 120 virtual machines (at our production datacenter) into a single Lenovo Flex chassis, saving at least 3 42U racks of floorspace and the power and environmentals to support them.
- It efficiently manages cpu and memory resources on a host among dozens of virtual machines. It also provide very efficient and reliable disk I/O
- It automates the build out of servers, saving hours over racking and building a physical server, and enabling consistent images on every server..
- It facilitates quick and easy snapshots of servers runtime state in order to test patches or application updates and quickly roll back in the event of failures.
- vCenter Virtual appliance is klunky and doesn't respond quickly.
- It's database can fill up its partition and crash the server unexpectedly, resulting in an unstable and unmanageable ESXi environment
- The vCenter web interface is not very useful and is missing several critical features, making the vim client essential for day to day use.
- This is hard to compute since we have been using it for my entire tenure here.
I have not used any other hypervisors.
