IBM Flex System V7000 Storage Node Introduction and Implementation Guide

Here are guidelines for planning for a SAN for Remote Copy.

Node canister ports on each IBM Storwize V7000 must be able to communicate with each 
other in order for the partnership creation to be performed. These ports must be visible to 
each other on your SAN. Proper switch zoning is critical to facilitating inter-cluster 
communication. 

The SAN zoning recommendation is as follows:

��

For each node canister, exactly two Fibre Channel ports should be zoned to exactly two 
Fibre Channel ports from each node canister in the partner cluster.

��

If dual-redundant inter-switch links (ISLs) are available, then the two ports from each node 
should be split evenly between the two ISLs, that is, exactly one port from each node 
canister should be zoned across each ISL. More details are available at the 
following address:

��

Additionally, all local zoning rules should be followed. A properly configured SAN fabric is 
key to not only local SAN performance, but Remote Copy. You can learn more about these 
rules at the following address:

Total Remote Copy volume 
capacity per I/O Group

1024 TB (This limit is the total capacity for all master and auxiliary 
volumes in the I/O group.) 

Fabrics: When a local fabric and a remote fabric are connected together for Remote 
Copy purposes, the ISL hop count between a local node and a remote node cannot 
exceed seven.
