Configure Virtual iSCSI Disks

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

Description

iSCSI virtual disks are used by users who have iSCSI storage requirements. Part of the virtual storage can be divided to provide services in iSCSI storage.

Precautions

The configured virtual iSCSI disk size can be pre-allocated or not. If it is pre-allocated, a 100G disk will occupy 100G of space on HCI. Storage space is allocated on demand if Pre-allocate is not selected.

HCI platforms must have virtual storage before configuring virtual iSCSI disks because iSCSI Virtual Disks are based on virtual storage.

In 6.9.0 and later versions, the 2+1 scenario supports configuring access IP and virtual IP pools. The client accesses through the virtual IP. When one of the nodes fails, the virtual IP will drift to another node, realizing iSCSI high availability.

Prerequisites

None.

Steps

  1. Go to Storage > Virtual Storage and select iSCSI Virtual Disks.

  1. Select the virtual datastore that will provide service to iSCSI and click Settings.

  1. Configure the iSCSI authentication username and password.

  1. Configure the Target Portal.

  1. On the iSCSI Virtual Disks tab click New to create new iSCSI Virtual Disk.

  1. Select the storage volume, configure the name, disk size, and accessible clients. Enabling Pre-allocation will give priority to occupying the SSD cache disk space. At the same time, you can limit the connected clients and whether to allow multiple clients to access them at the same time.
