The administrator should configure HCI Mesh on vSAN in order to share storage from one vSAN cluster to another vSAN cluster while preserving SPBM management end-to-end and applying the policy by the source vSAN cluster. According to the VMware documentation, "HCI Mesh enables vSAN clusters to share storage capacity with each other. You can create a stretched cluster with a maximum of four sites, or you can create a stretched cluster with multiple sites, with a maximum of 32 sites in a single vSAN domain. HCI Mesh supports the vSAN Stretched Cluster features, including Distributed RAID, Erasure Coding, and SPBM policy enforcement."

Setting proper VM/Host Group Rules and VM Storage Policy Affinity Rules are beneficial for several reasons Bandwidth is not unnecessarily sent across the inter-site link Lower inter-site bandwidth utilization In the situation where the alternate site is disconnected, the VM will continue to have access to its vmdk. from https://core.vmware.com/resource/vsan-stretched-cluster-guide#sec7341-sub5

Because Before you can create encrypted virtual machines, you must create an encryption storage policy. You create the storage policy once, and assign it each time you encrypt a virtual machine or virtual disk. https://docs.vmware.com/en/VMware-vSphere/7.0/com.vmware.vsphere.security.doc/GUID-7DE1ED8F-880B-421E-B27B-5AAA58454AFA.html

Some tools allow for measuring latency peaks. This unfortunately isn't ideal, as it can unfairly represent statistical outliers, which may very well occur when there is little to no I/O activity. The best way to understand the actual behavior of VM and application latencies is to observe in time based performance graphs. Depending on the level of detail, you may need to measure at the individual VMDK level. Become familiar with these graphs to determine what is normal, and what is not for that given application. This is where you can use built-in functionality of vCenter and the vSAN performance service metrics to gather this information.
