February 3, 2003 EMC CLARiiON Open Systems Configuration Guide CAUTION: Be careful when attempting to connect two previously isolated fabrics with a new ISL. If a parameter conflict exist (identical domain IDs, for example), the resulting fabric might be segmented, and not joined to form a single fabric. Number of Fabrics If any server on a SAN with departmental switches (DS-8B, DS-16B, DS-16B2, DS-32B2, DS-16M, DS-16M2, DS-24M2, DS-32M, DS-32M2) has multiple HBA ports, the SAN must have either 2 separate fabrics with 1 to 16 switches or 1 fabric with 2 switches maximum. Multiple HBA-port servers are supported in a SAN with 1 fabric consisting of only Director class Fibre Channel switches up to the maximum number of Director class Fibre Channel switches supported in such a fabric. CX200, CX400, CX600, FC4500, FC4700, or FC53001 Single SP Port Connection to Fabric In a SAN with 1 multi-switch fabric, connect one SP A port to one switch and one SP B port to another switch. In a SAN with 2 fabrics, connect one SP A port to one fabric and one SP B port to the other fabric. CX600 Multiple SP Port Connections to One Multi-Switch Fabric Either Connect SP A ports 0 and 1 and SP B ports 2 and 3 to one switch and SP A ports 2 and 3 and SP B ports 0 and 1 to another switch Or Connect SP A ports 0 and 2 and SP B ports 1 and 3 to one switch and SP A ports 1 and 3 and SP B ports 0 and 2 to another switch. Note: Connecting port 3 of each SP to different switches, makes these connections ready for remote mirroring through switches and allows access to both SPs. CX600 Multiple SP Port Connections to Two Fabrics Either Connect SP A ports 0 and 1 and SP B ports 2 and 3 to one fabric and SP A ports 2 and 3 and SP B ports 0 and 1 to the other fabric Or Connect SP A ports 0 and 2 and SP B ports 1 and 3 to one fabric and SP A ports 1 and 3 and SP B ports 0 and 2 to the other fabric.

CAUTION:
Be careful when attempting to connect two previously isolated fabrics with a new ISL. If a parameter
conflict exist (identical domain IDs, for example), the resulting fabric might be segmented, and not joined to form a
single fabric.
Number of Fabrics
If any server on a SAN with departmental switches (DS-8B, DS-16B, DS-16B2, DS-32B2, DS-16M, DS-16M2,
DS-24M2, DS-32M, DS-32M2) has multiple HBA ports, the SAN must have either 2 separate fabrics with 1 to 16
switches or 1 fabric with 2 switches maximum. Multiple HBA-port servers are supported in a SAN with 1 fabric
consisting of only Director class Fibre Channel switches up to the maximum number of Director class Fibre
Channel switches supported in such a fabric.

Single SP Port Connection to Fabric
In a SAN with 1 multi-switch fabric, connect one SP A port to one switch and one SP B port to another switch.
In a SAN with 2 fabrics, connect one SP A port to one fabric and one SP B port to the other fabric.
CX600 Multiple SP Port Connections to One Multi-Switch Fabric
Either
Connect SP A ports 0 and 1 and SP B ports 2 and 3 to one switch and SP A ports 2 and 3 and SP B ports 0 and 1 to
another switch
Or
Connect SP A ports 0 and 2 and SP B ports 1 and 3 to one switch and SP A ports 1 and 3 and SP B ports 0 and 2 to
another switch.
Note: Connecting port 3 of each SP to different switches, makes these connections ready for remote mirroring
through switches and allows access to both SPs.
CX600 Multiple SP Port Connections to Two Fabric
s
Either
Connect SP A ports 0 and 1 and SP B ports 2 and 3 to one fabric and SP A ports 2 and 3 and SP B ports 0 and 1 to
the other fabric
Or
C
onnect SP A ports 0 and 2 and SP B ports 1 and 3 to one fabric and SP A ports 1 and 3 and SP B ports 0 and 2 to the
other fabric.
Note: Connecting port 3 of each SP to different fabrics, makes these connections ready for remote mirroring
through switches and allows access to both SPs.
CX400, FC4700
Multiple SP Port Connections to One Multi-Switch Fabric
Connect SP A port 0 and SP B port 1 to one switch and SP A port 1 and SP B port 0 to another switch. Connecting
port 1 of each SP to different fabrics, makes these connections ready for remote mirroring through switches and
allows access to both SPs.
CX400, FC4700 Multiple SP Port Connections to Two Fabrics
Connect SP A port 0 and SPB port 1 to one fabric and SP A port 1 and SP B port 0 to the other fabric. Connecting
port 1 of each SP to different fabrics, makes these connections ready for remote mirroring through switches and
allows access to both SPs.
