To ensure that any virtual machines that are created are placed in the appropriate site in a vSAN Stretched Cluster, it is necessary to create VM/Host groups for the two sites. This allows for the definition of where VMs can be placed within the stretched cluster. Additionally, once the groups are created, the virtual machines need to be placed in the correct VM group. This ensures that VMs are correctly assigned to the site-specific groups, fulfilling the requirement to manage VM placement accurately.
To create a Kerberos-secured NFS v4.1 file share, the minimally required information during the configuration of the File Service includes the Active Directory Domain, User Account, and Password. The Active Directory Domain integrates the NFS file share with the Windows Active Directory environment for authentication services, while the User Account and Password establish the necessary credentials and permissions.
In a vSAN ESA cluster with four nodes, the storage policies that can be satisfied are FTT=1 (RAID-5 Erasure Coding) and FTT=1 (RAID-1 Mirroring). This is because FTT=1 (RAID-5 Erasure Coding) requires a minimum of four nodes to distribute data and parity information, providing tolerance for one node failure. Similarly, FTT=1 (RAID-1 Mirroring) requires at least three nodes, where data is mirrored to one other node to offer redundancy. Policies like FTT=2 or FTT=3 would require more than four nodes to achieve the necessary replication and redundancy.
The absence of vSAN performance statistics on the cluster summary page is due to the vSAN performance service not being enabled. The vSAN performance service is responsible for collecting and displaying performance metrics. Without enabling this service, performance statistics cannot be viewed in the graphical format on the cluster summary page.
The maximum number of capacity disks that an administrator can have in disk groups on a single vSAN OSA host is 35. This is calculated based on having a maximum of 5 disk groups per host, with each disk group containing up to 7 capacity devices, resulting in a total of 35 capacity devices.
