Here we will examine the various features and best practices that encompass Virtual SAN. We will examine multiple failure scenarios and ways to plan around them.
When provisioning Virtual SAN hosts, it is important to consider the various failure scenarios that can happen. The most common failure, being hard drive failure, requires the data on the drive to be moved to another device. This happens automatically in the case of a hardware fault. Or can be manually triggered by deleting the disk from the vCenter GUI. Virtual SAN clusters should always have enough resources to tolerate a single host failure. Close monitoring will be required to ensure the resources don't expand past the single host failure scenario. If the hosts are not identical, then we must have enough free resources to match the largest host or host with the largest capacity of each resource.
Given that multiple host failures are problematic for Virtual...
