Multipathing configuration maximums for IBM System p hosts

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

Table 1 provides the maximum virtual disks (VDisks) and paths per VDisk for the subsystem device driver (SDD) and the subsystem device driver path control module (SDDPCM).

Table 1. Configuration maximums for SDD and SDDPCM on IBM System p AIX hosts
Object	SDD maximum	SDDPCM maximum	Description
VDisk (HDisk)	512	N/A	The maximum number of VDisks that can be supported by the SDD (per host object). The maximum number of VDisks is enforced by the SAN Volume Controller.
Paths per VDisk	8	N/A	The maximum number of paths to each VDisk. 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.
