Planning the Fabric

Hyper Messaging Protocol (HMP)

Chapter 2

Instead, all of the traffic will be sent over a single connection with no failover

capability and without the performance increase that would come from balancing the

load over multiple connections.

• Maximum Cable Lengths:

HF1 (copper): The maximum distance between two nodes or between a node and a

switch is 60 ft. (2 standard cable lengths are sold and supported: 35 ft. and 60 ft.)

HMP supports up to four HF1 switches connected in series with a maximum cable

length of 60 ft. between the switches and 60 ft. between switches and nodes.

HF2 (fibre): The maximum distance is 200m (4 standard cable lengths are sold and

supported: 2m, 16m, 50m and 200m).

HMP supports up to four HF2 switches connected in series with a maximum cable

length of 200m between the switches and 200m between switches and nodes.

HMP supports up to 4 hybrid HF1/HF2 switches connected in series with a

maximum cable length of 60 ft. between copper ports and 200m between fibre ports.

• HMP is supported on the PCI 4X adapters, A6092A and A6386A.

• HMP is supported on A400, A500, rp2400, rp2450, rp54xx (N-class), rp74xx (L-class),

rp8400, and Superdome servers running 64 bit HP-UX.

• HMP is supported on J-class, B-class and C-class workstations running 64 bit

HP-UX when patch number PHNE_25485 is installed.

• HMP is supported on HyperFabric from HF version B.11.00.11 forward and from HF

version B.11.11.01 forward.

• HMP is not supported on V-class, A180 or A180C servers.

• HMP is not supported on 32 bit versions of HP-UX.
