Disk configuration considerations (vSAN OSA)

Each node in a vSAN Original Storage Architecture (OSA) cluster contributes one or more disk groups to the cluster. A disk group contains one cache disk and one or more capacity disks. Best practice is to include a minimum of two capacity disks per disk group for performance and data availability. Review the disk details before configuring the disks using the VX Deployer.

Note
All ThinkAgile VX nodes in the cluster must use the same disk configuration.

Note

  1. If the hosts in the cluster are vSAN ESA ready (Yes is listed in the vSAN ESA Ready column), the VX Deployer automatically deploys VMware ESA if all hosts in the cluster meet the requirements for ESA. For more information, see the following topic:
