Model numbering
The M-series switches typically use the numbering scheme x/y:
x—The highest speed at which the switch ports can operate, measured in Gb/s
y—The number of switch ports
For example, the HP StorageWorks Edge Switch 2/32 is a 2 Gb/s switch with 32 ports.
The 4 Gb/s and 2 Gb/s switch ports autonegotiate the signaling speed. For example, when you
connect a 4 Gb/s or 2 Gb/s port directly to a 1 Gb/s port, both ports run at 1 Gb/s in each direction.
If the ports are not directly connected, the fabric switch that connects the ports determines the signaling
speed.
Model naming
The M-series switches are typically called HP StorageWorks Edge Switches or Directors. Directors are
core (enterprise-class) switches. The Edge Switch 2/32 is a mid-range edge switch. The Edge Switch
2/12 and 2/24 are entry-level edge switches. The M-series embedded switch for HP p-Class
BladeSystem servers is called the McDATA 4 Gb SAN Switch.
Switch models
Table 60
describes the M-series switches supported by HP (1 Gb/s, 2 Gb/s, and 4 Gb/s M-series
Fibre Channel switch).
HP supports all M-series switches in a fabric if you:
Use the firmware versions listed in
same version when configured in a single-fabric or multi-fabric SAN (see
Table
61, and
BladeSystem must be compatible with the firmware used on HP StorageWorks Edge Switches and
Directors. When updating switch firmware, you can use two successive switch firmware versions
temporarily in a single-fabric or multi-fabric SAN.
Follow the fabric rules. (See
For the latest information on supported M-series switches and firmware versions, see the HP SAN
Infrastructure website: http://h18006.www1.hp.com/storage/saninfrastructure.html.
