* vLockstep - Keeps Primary and Secondary VM's in sync | |||
* On-Demand Fault Tolerance - Temporary FT, configured for a VM during a critical time | |||
'''Prerequisites''' | |||
* Cluster | |||
** HA and host monitoring must be enabled | |||
** Host certificate checking must be enabled | |||
* ESX's | |||
** Separate VMotion and FT Logging NIC(s) configured (should be different subnets for each) | |||
** Same ESX software version and patch level (FT must be temporarily disabled during ESX software upgrades) | |||
** FT-compatible processor | |||
** Host certified by OEM as FT-capable | |||
** Host BIOS must have Hardware Virtualisation (eg Intel VT) enabled | |||
* VM's | |||
** VMDK files must be thick provisioned with Cluster Features enabled | |||
** Run supported OS (generally all, may require reboot to enable FT) | |||
'''Unsupported''' | |||
* Snapshots (must be removed/committed before FT enabled) | |||
* Storage VMotion | |||
* DRS | |||
* SMP - Only single vCPU supported | |||
* Physical RDM | |||
* CD-ROM or Floppy media/ISO not on shared storage | |||
* Paravirtualised guests | |||
* NPIV | |||
* NIC Passthrough | |||
'''Setup''' | |||
# Enable host certificate checking | |||
# Configure VMkernel networking | |||
# Create HA Cluster and perform Profile Compliance | |||
# Turn on FT for appropriate VM's | |||
