February 3, 2003 EMC CLARiiON Open Systems Configuration Guide MirrorView Configuration Rules Supported Storage Systems CX400, CX600, and FC4700, mirrored to themselves or each other. (See the EMC Support Matrix for the required revisions of FC4700 Access Logix and MirrorView). Port 3 on each CX600 SP and port 1 on each CX400 or FC4700 SP is used for remote mirror connections. SP mirror ports and SP non-mirror ports (host I/O ports) must not be in the same switch zone. If an HBA port is using CX600 SP ports 0, 1, 2, and/or port 3 for normal I/O and is also using port 3 for remote mirror data, you should have one switch zone for the HBA port and the normal I/O ports and one zone for the HBA port and the ports for remote mirror data. Similarly, if an HBA port is using CX400 or FC4700 SP port 0 and/or port 1 for normal I/O and is also using port 1 for remote mirror data, you should have one switch zone for the HBA port and the normal I/O ports and one zone for the HBA port and the ports for remote mirror data. Note: In a MirrorView-over-IP configuration, the mirror ports are dedicated to mirroring and cannot be used for host I/O. Models MV-Tx where x is the storage tier. Software Requirements Access Logix. Mirror Images 1 primary image per mirror. Mirroring a system disk is not supported for MirrorView-over-IP. 0 to 2 secondary images per mirror. For MirrorView-over-IP, only 0 to 1 secondary images. For a CX400 storage system, 50 images maximum (total of primary and secondary images) per storage system with 25 primary images maximum configured to use the write intent log. For a CX600 or FC4700 storage system, 100 images maximum (total of primary and secondary images) per storage system with 50 primary images maximum configured to use the write intent log. Note: A storage system can have only one image of a mirror. Supported Servers All. SP Port Connections SP A port 3 (CX600) or port 1 (CX400, FC4700) and SP B port 3 (CX600) or port 1 (CX400, FC4700) on both the primary and secondary storage systems must run at the same Fibre Channel link speed. SP Port Direct Connections - Direct connection between: - SP A port 3 (CX600) or port 1 (CX400, FC4700) on primary and secondary storage systems - SP B port 3 (CX600) or port 1 (CX400, FC4700) on primary and secondary storage systems SP Port Switch Connections - 2 switch zones: - SP A port 3 (CX600) or port 1 (CX400, FC4700) on primary storage system and SP A port 3 (CX600) or port 1 (CX400, FC4700) on secondary storage system - SP B port 3 (CX600) or port 1 (CX400, FC4700) on primary storage system and SP B port 3 (CX600) or port 1 (CX400, FC4700) on secondary storage system If a host HBA port uses port 3 (CX600) or port 1 (CX400, FC4700) on SP A and SP B of the primary or secondary storage system for host I/O it should be included in separate zones. NOTE: A storage system can have mirroring connections to a maximum of four other storage systems concurrently. Management of Primary and Secondary Storage Systems A single Navisphere management station must manage both storage systems. Note: Both the primary and secondary storage systems can each contain secondary mirror images as well as the primary mirror image (cross mirroring). Document Rev 19 Page 19 EMC Confidential

MirrorView Configuration Rules
Supported Storage Systems
CX400, CX600, and FC4700, mirrored to themselves or each other. (See the
EMC Support Matrix
for the required
revisions of FC4700 Access Logix and MirrorView). Port 3 on each CX600 SP and port 1 on each CX400 or FC4700
SP is used for remote mirror connections. SP mirror ports and SP non-mirror ports (host I/O ports) must
not
be in
the same switch zone. If an HBA port is using CX600 SP ports 0, 1, 2, and/or port 3 for normal I/O and is also
using port 3 for remote mirror data, you should have one switch zone for the HBA port and the normal I/O ports
and one zone for the HBA port and the ports for remote mirror data. Similarly, if an HBA port is using CX400 or
FC4700 SP port 0 and/or port 1 for normal I/O and is also using port 1 for remote mirror data, you should have
one switch zone for the HBA port and the normal I/O ports and one zone for the HBA port and the ports for
remote mirror data.
Note:
In a MirrorView-over-IP configuration, the mirror ports are dedicated to mirroring and cannot be used for
host I/O.
Models
MV-Tx where x is the storage tier.
Software Requirements
Access Logix.
Mirror Images
1 primary image per mirror. Mirroring a system disk is not supported for MirrorView-over-IP.
0 to 2 secondary images per mirror. For MirrorView-over-IP, only 0 to 1 secondary images. For a CX400 storage
system, 50 images maximum (total of primary and secondary images) per storage system with 25 primary images
maximum configured to use the write intent log. For a CX600 or FC4700 storage system, 100 images maximum
(total of primary and secondary images) per storage system with 50 primary images maximum configured to use
the write intent log.
Note: A storage system can have only one image of a mirror.
Supported Servers
All.
SP Port Connections
SP A port 3 (CX600) or port 1 (CX400, FC4700) and SP B port 3 (CX600) or port 1 (CX400, FC4700) on both the
primary and secondary storage systems must run at the same Fibre Channel link speed.
SP Port Direct Connections
- Direct connection between:
- SP A port 3 (CX600) or port 1 (CX400, FC4700) on primary and secondary storage systems
- SP B port 3 (CX600) or port 1 (CX400, FC4700) on primary and secondary storage systems
SP Port Switch Connections
- 2 switch zones:
- SP A port 3 (CX600) or port 1 (CX400, FC4700) on primary storage system and SP A port 3 (CX600) or
port 1 (CX400, FC4700) on secondary storage system
- SP B port 3 (CX600) or port 1 (CX400, FC4700) on primary storage system and SP B port 3 (CX600) or
port 1 (CX400, FC4700) on secondary storage system
If a host HBA port uses port 3 (CX600) or port 1 (CX400, FC4700) on SP A and SP B of the primary or secondary
storage system for host I/O it should be included in separate zones.
N
OTE
:
A storage system can have mirroring connections to a maximum of four other storage systems concurrently.
Management of Primary and Secondary Storage Systems
A single Navisphere management station must manage both storage systems.
Note:
Both the primary and secondary storage systems can each contain secondary mirror images as well as the
primary mirror image (cross mirroring).
