Determine memory requirements for network objects

To determine the memory requirements for your network objects, use Memory requirements by IP Availability Managercomponent with the number of ports and interfaces that you either obtained or estimated.

Memory requirements by IP Availability Managercomponent presents the memory requirements per network object for the IP Availability Manager.

Table on page presents the memory requirements per network object for the combined deployment of the IP Availability Managerand IP Performance Manager(AM-PM).

The values in the tables were obtained by observing memory requirements of customer topologies and applying linear regression to the results. The values represent VMware’s best compromise between accuracy and simplicity.

Memory is based on UNIX ps RSS working set size. These values measure the amount of physical memory consumed rather than the amount of address space consumed. The memory observations were arrived at using the following commands on the various platforms:

Unix:

"ps -opid,ppid,rss,comm,args [PID]"

RSS is reported in kiloBytes.

PerfMon is reported in bytes.

Table 1. Memory requirements by IP Availability Managercomponent
Operating system	Memory required for network object support by IP Availability Manager
Operating system	Fixed	Per interface	Per unmanaged port	Per managed port
Linux	130M	40K	15K	140K
Solaris	255M	45K	15K	140K

Table 2. Memory requirements for combined deployment of AM-PM
Operating System	Memory required for network object support by IP Availability Manager& IP Performance Manager(AM-PM)
Operating System	Fixed	Per interface	Per unmanaged port	Per managed port
Linux	170M	60K	20K	350K
Solaris	310M	60K	15K	350K

Note:

The per managed port measures vary in the regression results as managed ports tended to be a relatively smaller percentages of the topologies.
