IP partnership performance best practices

A number of factors affect the performance of an IP partnership. Some of these factors are latency, link speed, number of intersite links, host I/O, MDisk latency, and hardware.

The following actions might help improve this performance. See IP partnership requirements for additional considerations.

To avoid losing synchronization during node failover, use policy-based replication or Global Mirror with change volumes. These modes of replication provide consistency protection and restarts replication automatically.

If you choose to use compression and IP partnership in the same system, certain hardware updates or configuration choices might help increase IP partnership performance:

If you choose to create an IP partnership on a system that has compressed volumes, and you have multiple I/O groups, configure ports for the IP partnership in I/O groups that do not contain compressed volumes.
Use a different port for IP partnership traffic, which is not used for iSCSI host, iSCSI virtualization, iSCSI backend, iSER host attachment, and RDMA clustering. Also, use a different VLAN ID for iSCSI host I/O and IP partnership traffic.
