VMware has updated its VMFS Technical Overview paper for vSphere 5.1. The Paper titled VMware vSphere VMFS Technical Overview and Best Practices contains 17 pages and details how the VMware File System (VMFS) works. VMFS increases resource utilization by providing multiple virtual machines with shared access to a consolidated pool of clustered storage.
VMFS provides the basis for other VMware services like virtual machine snapshots, VMware vSphere Thin Provisioning, VMware vSphere vMotion, VMware vSphere Distributed Resource Scheduler (vSphere DRS), VMware vSphere High Availability (vSphere HA), VMware vSphere Storage DRS and VMware vSphere Storage vMotion.
The paper contains the following sections:
- Introduction, background and VMFS Technical Overview
- Features and Benefits of VMFS
- Best Practices for Deployment and Use of VMFS
