CLARiiON SAN fan-in and fan-out configuration rules

Fan-In Rule:

A server can be zoned to a maximum of four storage systems.

Fan-Out Rule:

· For FC5300 with Access Logix software - 1 - 4 servers (eight initiators) to 1 storage system.
 
· For FC4500 with Access Logix - 15 servers to 1 storage system; each server with a maximum of one (single) path to an SP.


·    For FC4700 with Base or Access Logix software 8.42.xx or higher - 32 initiators per SP port for a maximum of 128 initiators per FC4700. Each port on each SP supports 32 initiators. Ports 0 and 1 on each SP in a FC4700 handles server connections. Port 1 on each SP in a FC4700 with MirrorView also handles remote mirror connections. In a remote mirror configuration, each path between SP A port 1 on one storage system and SP A port 1 on another storage system counts as one initiator for each port 1. Likewise, each path between SP B port 1 on one storage system and SP B port 1 on another storage system counts as one initiator for each port 1.


·    For FC4700 with Base or Access Logix software 8.41.xx or lower - 15 servers to 1 storage system; each
server with a maximum of one (single) path to an SP.

·     For CX200 - 15 initiators per SP, each with a maximum of one (single) path to an SP; maximum of 15
servers.

·       Fan-Out for CX300 - 64 initiators per SP for a maximum of 128 initiators per storage system.

·    For CX400 - 32 initiators per SP port for a maximum of 128 initiators per CX400. Each port on each SP
supports 32 initiators. Ports 0 and 1 on each SP in a CX400 handles server connections. Port 1 on each
SP in a CX400 with MirrorView also handles remote mirror connections. In a remote mirror
configuration, each path between SP A port 1 on one storage system and SP A port 1 on another storage
system counts as one initiator for each port 1. Likewise, each path between SP B port 1 on one storage
system and SP B port 1 on another storage system counts as one initiator for each port 1.

·     Fan-Out CX500 - 128 initiators per SP and maximum of 256 initiators per CX500 available for server
connections. Ports 0 and 1 on each SP handle server connections. Port 1 on each SP in a CX500 with
MirrorView/A or MirrorView/S enabled also handles remote mirror connections. Each path used in a
MirrorView or SAN Copy relationship between two storage system counts as an initiator for both
storage systems.

·       For CX600 - 32 initiators per SP port and maximum of 256 initiators per CX600 available for server
connections. Ports 0, 1, 2, and 3 on each SP in any CX600 handle server connections. Port 3 on each SP
in a CX600 with MirrorView also handles remote mirror connections. In a remote mirror configuration,
each path between SP-A port 3 on one storage system and SP-A port 3 on another storage system counts
as one initiator for each port 3. Likewise, each path between SP-B port 3 on one storage system and SPB
port 3 on another storage system counts as one initiator for each port 3.

·         Fan-Out CX700 - 256 initiators per SP and maximum of 512 initiators per CX700 available for server
connections. Ports 0, 1, 2, and 3 on each SP in any CX700 handle server connections. Port 3 on each SP
in a CX700 with MirrorView/A or MirrorView/S enabled also handles remote mirror connections. Each
path used in a MirrorView or SAN Copy relationship between two storage system counts as an initiator
for both storage systems

·        An initiator is any device with access to an SP port. Each port on each SP supports 32 initiators. Check
with your support provider to confirm that the above rules are still in effect.
