How are FAS nodes, mounts, and aggregates segregated in HA pairs?

Last Updated:

Applies to

All versions of ONTAP or Data ONTAP


  • HA Pairs have two separate nodes, on two separate motherboards, that only share same disks
  • Each node creates groups of disks called Aggregates, which contain FlexVols that are mounted over CIFS, FCP, iSCSI, or NFS
  • One node does not access the other's Aggregates, except in takeover
  • To utilize the resources of both nodes, talk to your account team about setting up a FlexGroup or using multiple LUNs striped as a volume group on the host side.
