VMware vCenter Update Manager (also known as VUM) provides a patch management framework for VMware vSphere. IT administrators can use it to patch and upgrade ESX/ESXi hosts, upgrade VMware Tools and virtual hardware for virtual machines, as well as upgrade virtual appliances.
A white paper that examines the performance of VUM is available. This paper includes some interesting information, including:
- VUM deployment recommendations that maximize performance
- A look at the latencies of common VUM operations
- The resource consumption profile of VUM operations for CPU, network, disk, and database
- How much time it takes to remediate a cluster sequentially vs. in parallel
- VUM performance in a low bandwidth, high latency, or lossy network
- How the use of bandwidth throttling affects host staging and remediation over LAN and WAN
- Performance tips and best practices
