How does Red Hat Hyperconverged Infrastructure (RHHI) support work?

Solution Verified - Updated -

Environment

  • Red Hat Virtualization (RHV) 4.4 with Red Hat Hyperconverged Infrastructure for Virtualization (RHHI-V) 1.8
  • RHV 4.3 with RHHI 1.7

Issue

  • How does Red Hat Hyperconverged Infrastructure work, both in terms of entitlements needed as well as layering of Red Hat Virtualization plus its guests and Red Hat Storage?

Resolution

  • Red Hat Hyperconverged Infrastructure (RHHI) is an offering based on Red Hat Virtualization (RHV) and Red Hat Gluster Storage (RHGS).

  • The only supported way to use RHV hosts as Hyperconverged (i.e. to provide Red Hat Storage and Virtualization capabilities at the same time) is through RHHI deployment following RHHI-V official documentation.

    • The supported hosts are RHVH hosts only (not RHEL hosts).
    • RHGS version should match with the corresponding version shipped with RHVH. No manual updates of glusterfs packages allowed.
    • Max of 12 nodes in the cluster, in increments of three: 3, 6, 9, 12.
    • All hosts should be part of both the virt cluster and gluster trusted storage pool.
    • The nodes in the virt cluster should be the same set of nodes available in gluster cluster as well.
    • SHE deployment mode, no standalone RHV Manager allowed.

  • A RHHI-V entitlement is needed as well. It isn't supported to run a RHHI environment with just RHV + RHGS entitlements; though using Red Hat Gluster Storage for simply hosting RHV guests, i.e. to use RHGS as a RHV Storage Domain, running on a different server, is fine.
