To ensure that a single rack failure is not going to affect the data availability, while minimizing the number of racks used, the administrator has to do the following:

• Distribute servers across at least three different racks. This is because vSAN supports up to three fault domains per cluster, which can be used to tolerate one or two failures. If only two racks are used, then only one failure can be tolerated4
• Configure three fault domains. A fault domain is a logical grouping of hosts that share a common failure point, such as a rack or a power supply. By configuring fault domains, vSAN can place replicas of an object across different fault domains, so that a failure within one fault domain does not result in data loss orunavailability4 References: 4: VMware vSAN Specialist v2 Exam Preparation Guide, page 13

To configure vSAN Direct, the administrator must meet two requirements: a valid vSAN license for the vSAN cluster and unclaimed disks in the hosts for vSAN Direct. A vSAN license is required to enable vSAN features and services, including vSAN Direct. Unclaimed disks are local storage devices that are not used by vSAN or any other service, and can be claimed by vSAN Direct to create datastores for persistent storage. The other options are not requirements for vSAN Direct. HA is an optional feature that can be enabled on any cluster, but is not specific to vSAN Direct. A dedicated network for vSAN Direct is not necessary, as vSAN Direct uses the same network as vSAN. An integration with vSAN File Services is not required, as vSAN Direct does not provide file shares, but block storage. References: Set Up vSAN Direct for vSphere with Tanzu; vSAN Licensing Guide

To prevent vCenter notifications of vSAN Health status during a scheduled maintenance window, the administrator can disable the alarm from the HTML client. This will suppress the alerts for a specified duration or until the alarm is re-enabled. Disabling the performance service, running performance diagnostics, or disabling SNMP service will not affect the vSAN Health status notifications.
