A certain amount of memory must be reserved for system resources. To view the total amount of installed memory and the amount of configured memory, run the Configuration/Setup Utility program and select System Summary from the menu. For additional information, see Chapter 3, "Configuring the server," on page 49. v The following tables show examples of maximum memory capacity when the server operates in mirroring and non-mirroring modes, using identical single-rank, x8 technology or double-rank, x4 technology DIMMs. The memory capacity is dependent on the size and technology of the DIMMs that you install.
