Shared Virtual Disk of External Storage

{{ $t('productDocDetail.updateTime') }}: 2026-01-05

Description

In the storage-compute separation scenario, if an Oracle RAC database cluster service runs on the external storage, multiple VMs will share one data disk. HCI supports creating shared virtual disks using external storage resources and mounting them to multiple VMs for running cluster services such as Oracle RAC/MQ.

Precautions

Shared virtual disks will be excluded during export, backup, CDP backup, snapshot, and disaster recovery for VMs.

Shared virtual disks only support cold capacity expansion.

Shared virtual disks do not support hot cloning.

Shared virtual disks do not support Windows server failover clustering.

Shared virtual disks do not support cross-datastore live migration.

VMs using shared virtual disks do not support cross-cluster live migration.

VMs using shared virtual disks can only be converted to VM templates after the shared virtual disks are deleted.

Shared virtual disks of VMs created through the Oracle RAC Wizard must be on the same LUN.

Prerequisites

None.
