Diagnostics and <strong>Troubleshooting</strong> <strong>Reference</strong> <strong>Manual</strong> – Virtual SAN<br />

Understanding components and component count<br />

Note: The component limit per host was 3,000 for Virtual SAN version 5.5. Virtual SAN<br />

Version 6.0 increased this limit count to 9,000.<br />

The disk limits are worth noting regularly via the vsan.check_limits RVC<br />

command to ensure that the limits are not being reached.<br />

In this example, a test VM using the following VM Storage Policy settings has been<br />

deployed:<br />

Number of Failures to Tolerate (FTT) = 1<br />

Number of Disk Objects to Stripe (SW) = 2<br />

The way this virtual machine’s object are deployed and distributed across the<br />

Virtual SAN cluster is looked at next, as well as verifying that the policy has indeed<br />

taken effect.<br />

Examining components via the vSphere web client<br />

One can examine some of the components via the vSphere web client, and in this<br />

example (using vSphere 5.5), they show the following layout for the VM Home<br />

Namespace and the VMDK. Here is the VM Home Namespace object and its<br />

components:<br />
