Multipathing configuration maximums for IBMSystem p hosts

When you configure, keep in mind the maximum configuration for IBM^®System p AIX hosts.

Table 1 provides the maximum volumes and paths per volume for the subsystem device driver (SDD) and the subsystem device driver path control module (SDDPCM).

Table 1. Configuration maximums for SDD and SDDPCM on IBMSystem p AIX hosts
Object	SDD maximum	SDDPCM maximum	Description
Volume (HDisk)	512	N/A	The maximum number of volumes that can be supported by the SDD (per host object). The maximum number of volumes is enforced by the Lenovo Storage V7000 system. Note: The Lenovo Storage V7000 system supports 2048 volumes with Aix PCM using FC, FCoE or SAS.
Paths per volume	8	N/A	The maximum number of paths to each volume. The number of paths directly corresponds with the resulting path-failover time. Although the maximum number of supported paths is eight, do not use more than two paths per adapter port.
