vSAN 2-Node Configuration Basics

• vSAN 2-node basics– Both nodes must be in a single physical location

– Only supports PFTT=1, mirroring (VM objects are mirrored across two nodes, FTT=1)

– Witness host required as the tiebreaker

– 3 fault domains (Witness host included)

– Uses per-socket vSAN licenses

• Witness host – Virtual appliance running ESXi (multiple sizes depending on VM count)

– Receives Witness traffic from the two nodes

– Must run outside of cluster and requires Witness traffic separation

▪ https://blogs.vmware.com/virtualblocks/2018/05/16/witness-host-traffic-tagging/

– Can run on a host within the same rack, but not in the 2-node cluster

– More detail in the vSAN 2-node sizing section of the 2-node guide:

https://storagehub.vmware.com/t/vmware-vsan/vsan-2-node-guide/vsan-witness-appliance-sizing/


What Else Should You Consider?

• For non-deployed appliances running VxRail OS older than 4.7.100:– Must re-image VxRail OS to 4.7.100+ (part of standard ProDeploy service offering)

• Net new clusters only – cannot use node removal from an existing VxRail cluster to form the 2-node configuration

• vCenter– Must use customer-supplied vCenter to manage

• Size of workloads– Best practice to run less than 50% of a nodes resource load, so a single node can bear full cluster load in case

of a node failure

• WAN requirements– RTT between Witness and data nodes up to 200ms

– Bandwidth of at least 2Mbps

• ESXi 6.7 or 6.5 U2 installed on BOSS with back-up (RASR) installed on SD cards.

• Identity Module – The identity module self-identifies the chassis as a vSAN Ready Node which streamlines deployment, updates, etc.

• OMIVV is now vSAN aware due to the identity module.

• Chassis with NO OS option is available. This will allow a GPU to be installed from the factory for VDI workloads.

• OS install options • BOSS with no SD cards• BOSS with SD cards• SD cards with no BOSS

• vSAN Ready Node unique chassis can still be repurposed at a later date if desired.
