HP StorageWorks Fabric Interoperability: Merging Fabrics Based on M-series and B-series Fibre Channel Switches Application Notes (AA-RUQQL-TE, November 2009)

M-series-aware features
Table 1 describes the features that are available fabric-wide in an M-series environment.

CommentsFeature
FC frame header uses the SID and DID according to the domain offset
setting.
Switch ASIC
Allows you to perform standalone and fabric-wide tasks such as basic
switch and port configuration

Note:
nl
DCFM earlier than V10.3.0 requires at least one B-series switch in the
fabric.
B-series management interface
(such as EFCM, DCFM, and
WebTools)
Supported with McDATA Open Fabric mode and McDATA Fabric modeCoordinated HCL
Displays the firmware version; for example:
• M-series format: 9.7.2
• B-series format: 6.1
ESS
In a mixed configuration, the fabric issues the ESC command to determine
the domain ID offset setting of adjacent switches. An incompatible domain
ID offset causes ISLs to segment. Fabric also autonegotiates the credit
model usage:
• R-RDY for connection to an M-series switch
• VC-RDY for connection to a B-series switch
Fabric
Converts the header of FC frames to use the correct SID and DID according
to the domain offset setting
FC
Supported with McDATA Open Fabric mode and Homogeneous/McDATA
Fabric mode
1
FCR E_Port SANtegrity
Supported with:
• Homogeneous/McDATA Fabric mode only with FOS earlier than 6.3.0
• Homogeneous/McDATA Fabric and McDATA Open Fabric mode with
FOS 6.3.0 or later
FCR fabric OS L2 SANtegrity
The configure command displays the number of buffer credits allocated
to a port
Long distance
Displays the device PID with M-series domain offset
Name server
(nsShow, nsCamShow,
nsAllShow)
In Homogeneous/McDATA Fabric mode, zone activations can be
performed from any switch.
In McDATA Open Fabric mode, zone activations can be performed from
an M-series management tool only.
Zone activation

Homogeneous Fabric mode applies to M-series switches only.
