Planning the VMware Application
This section describes the principles for planning virtualization services.
HyperMetro Consistency Group
If the space for a VM is allocated across datastores, all HyperMetro LUNs mapped to the host cluster must be added to the same HyperMetro consistency group. If cross-datastore space allocation is not involved, you do not need to create a consistency group.
vMotion Network
The vMotion network is a migration network defined by a virtual cluster. When VMs are migrated in online mode between hosts, fast memory synchronization is required between hosts to achieve fast online migration. The latency must be less than 5 ms (the latency varies with versions and 5 ms is the recommended value). The 10GE network is recommended.
Host Layer Configuration
When the VMware ESXi cluster works with HyperMetro, host layer parameters must be configured for the Permanent Device Loss (PDL) and All Paths Down (APD) scenarios.
When the Hyper-V cluster works with HyperMetro, you must configure a proper cluster timeout period.
