Methods for service cluster support in virtualization


A service cluster consists of several servers and provides the same applications externally, such as Window Exchange, Active Directory, and SQL Server.
Users can simultaneously mount a shared disk to a maximum of four VMs (generally two) to form a cluster for virtualization. The cluster software controls service access to the disks.
In this case, the VM snapshot function is unavailable.
Virtualization is not recommended for service clusters based on shared disks.

Whether pVLAN is supported in virtualization
pVLAN is supported in virtualization, but the constraints are as follows: Using pVLAN can reduce VLAN usage. The master VLAN can be configured during system installation and the slave VLANs can be added gradually in subsequent phases. pVLAN and VRRP are mutually exclusive. If pVLAN is used, VRRP cannot be configured on aggregation switches, and the switches must be stacked.
