HPE VME iSCSI Dual-Fabric Topology
Tip:
Each host has 4 iSCSI paths to storage (2 controllers 2 fabrics). Multipath (MPIO) is required for GFS2 datastores.
Key Design Principles
-
Dual fabric design with separate switches, VLANs, and subnets per fabric
-
Minimum 2 storage NICs per host for multipath I/O
-
MTU 9000 (jumbo frames) end-to-end - host, switch, and array
-
GFS2 clustered filesystem with minimum 3 nodes for quorum
