552 Implementing the IBM Storwize V5000 Gen2 with IBM Spectrum Virtualize V8.1
In your IBM Storwize system, use the lssystem command to check the current system layer,
as shown in Example 10-2.

10.6.3 IP partnership limitations
The following prerequisites and assumptions must be considered before IP partnership
between two IBM Spectrum Virtualize systems can be established:
The IBM SAN Volume Controller or IBM Storwize systems are successfully installed with
V7.2 or later code levels.
The systems must have the necessary licenses that enable remote copy partnerships to
be configured between two systems. No separate license is required to enable IP
partnership.
The storage SANs are configured correctly and the correct infrastructure to support the
Spectrum Virtualize systems in remote copy partnerships over IP links is in place.
The two systems must be able to ping each other and perform the discovery.
The maximum number of partnerships between the local and remote systems, including
both IP and Fibre Channel (FC) partnerships, is limited to the current maximum that is
supported, which is three partnerships (four systems total).
Only a single partnership over IP is supported.
A system can have simultaneous partnerships over FC and IP, but with separate systems.
The FC zones between two systems must be removed before an IP partnership is
configured.
IP partnerships are supported on both 10 gigabits per second (Gbps) links and 1 Gbps
links. However, the intermix of both on a single link is not supported.
The maximum supported round-trip time is 80 milliseconds (ms) for 1 Gbps links.
The maximum supported round-trip time is 10 ms for 10 Gbps links.
Note: Consider the following rules for creating remote partnerships between the IBM SAN
Volume Controller and Storwize Family systems:
An IBM SAN Volume Controller is always in the replication layer.
By default, the IBM Storwize systems are in the storage layer but can be changed to the
replication layer.
A system can form partnerships only with systems in the same layer.
Starting in software V6.4, an IBM SAN Volume Controller or Storwize system in the
replication layer can virtualize an IBM Storwize in the storage layer.
