Figure 7 shows an example of a DB2 Extended Enterprise Edition hardware configuration.
Figure 7. DB2 Extended Enterprise Edition Hardware Configuration
DB2 Extended Enterprise Edition can run on a cluster of individual CPUs interconnected by shared memory (symmetric multiprocessors (SMP)), a dedicated high-speed communications switch (for example, HPS), or a LAN. The number of database partition servers in a configuration varies by platform. You should limit the number of database partition servers that communicate over a LAN to 16.
In practice, the number of database partition servers in a configuration is limited by the platform and the management tools available on each platform. For more information about configuration, refer to the Administration Guide.
For example, in an IBM RISC/6000 Scalable POWERparallel Systems (RISC/6000 SP) environment that is running AIX, the number of database partition servers is only limited by the possible size of an AIX RISC/6000 SP system.
In a Solaris environment, the number of database partition servers is limited by the size of the machines and the number of those machines that are clustered together. Forty database partition servers could be run on a clustered system of four Ultra Enterprise 6000s with ten CPUs each.
The following sections provide information that you should be familiar with before you configure your partitioned database system. Specifically, they describe:
