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 recommendations might help improve this performance.
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 Lenovo Storage V7000 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 iSCSI
host I/O and IP partnership traffic. Also, use a different VLAN ID
for iSCSI host I/O and IP partnership traffic.
