NIM case study
In the first section of this chapter we go through the performance tuning process for an AIX system that is using the Network Installation Management (NIM) software. Network Install Manager is a complex application which relies on several subsystems to provide software installation and maintenance in an AIX, or a mixed AIX/Linux environment (from AIX 5L V5.3).
NIM uses a client server model which provides clients with all the necessary resources for booting, installing, maintaining or diagnosing (AIX only) client machines. In a NIM environment, the following subsystems should be considered as candidates for performance tuning: network (TCP/IP), NFS, Virtual Memory Manager, Disk I/O and Logical Volume Manager.
