You can select a group of cache and capacity devices, and vSAN organizes them into default disk groups.
In this method, you select devices to create a disk groups for the vSAN cluster. You need one cache device and at least one capacity device for each disk group.
Note: Only the vSAN Data Persistence platform can consume vSAN Direct storage. The vSAN Data Persistence platform provides a framework for software technology partners to integrate with VMware infrastructure. Each partner must develop their own plug-in for VMware customers to receive the benefits of the vSAN Data Persistence platform. The platform is not operational until the partner solution running on top is operational. For more information, see
vSphere with Tanzu Configuration and Management.
Procedure
- Navigate to the vSAN cluster.
- Click the Configure tab.
- Under vSAN, click Disk Management.
- Click Claim Unused Disks.
- Select devices to add to disk groups.
- For hybrid disk groups, each host that contributes storage must contribute one flash cache device and one or more HDD capacity devices. You can add only one cache device per disk group.
- Select a flash device to be used as cache and click Claim for cache tier.
- Select an HDD device to be used as capacity and click Claim for capacity tier.
- Click Create or OK.
- For all-flash disk groups, each host that contributes storage must contribute one flash cache device and one or more flash capacity devices. You can add only one cache device per disk group.
- Select a flash device to be used as cache and click Claim for cache tier.
- Select a flash device to be used for capacity and click Claim for capacity tier.
- Click Create or OK.
To verify the role of each device added to the all-flash disk group, navigate to the Disk Role column at the bottom of the Disk Management page. The column shows the list of devices and their purpose in a disk group.
vSAN claims the devices that you selected and organizes them into default disk groups that support the
vSAN datastore.
