February 3, 2003 EMC CLARiiON Open Systems Configuration Guide Switch Zoning Zoning spans the entire fabric. EMC requires single-initiator zoning using the World Wide Port Name (WWPN) of the HBA port and the WWPNs of the SP ports. One server can have only one path to each SP, unless the server is running software that supports multi-path or alternate path access to the storage-system SP (see Paths from a Server to an SP (page 10). For information on configuring zones, refer to the switch manuals and release notes. IMPORTANT: Be sure to document all zoning parameters, including the WWPNs of HBA port and SP ports, for future reference. Remote Mirror Zoning See Fan-In Rule and Fan-Out Rule, "Storage Area Network (SAN) Configuration Rules" on page 9. If an HB A is using one or more SP ports for normal I/O and SP port 3 (CX600) or SP port 1 (CX400, FC4700) for normal I/O and remote mirror data, have one switch zone for the HBA port and the normal I/O ports and one zone for the HBA port and the remote mirror data ports. QuickLoops QuickLoop emulates Arbitrated Loop in a Fabric. • QuickLoop is supported only on DS-8B, DS-16B, and DS-16B2 switches. • One QuickLoop can be present on each switch or can span two switches. • Servers and storage systems within a QuickLoop must be configured for arbitrated loop.

Switch Zoning
Zoning spans the entire fabric. EMC requires single-initiator zoning using the World Wide Port Name (WWPN) of the
HBA port and the WWPNs of the SP ports.
One server can have only one path to each SP, unless the server is running software
that supports multi-path or alternate path access to the storage-system SP (see
Paths from a Server to an SP
(
page 10
).
For information on configuring zones, refer to the switch manuals and release notes.
IMPORTANT: Be sure to document all zoning parameters, including the WWPNs of HBA port and SP ports, for future
reference.
Remote Mirror Zoning
See Fan-In Rule and Fan-Out Rule,
“
Storage Area Network (SAN) Configuration Rules
”
on page 9. If an HB A is using
one or more SP ports for normal I/O and SP port 3 (CX600) or SP port 1 (
CX400,
FC4700) for normal I/O and remote
mirror data, have one switch zone for the HBA port and the normal I/O ports and one zone for the HBA port and the
remote mirror data ports.
QuickLoops
QuickLoop emulates Arbitrated Loop in a Fabric.
•
QuickLoop is supported only on DS-8B, DS-16B, and DS-16B2 switches.
•
One QuickLoop can be present on each switch or can span two switches.
•
Servers and storage systems within a QuickLoop must be configured for arbitrated loop.
