Chapter 5 Installing Additional Memory Memory Configuration Guidelines The HP NetServer is equipped with two memory boards. You remove and insert the board through the front of the server. The boards sit horizontally in two side-by-side bays, and plug into connectors on the server's midplane board. Each memory board supports four-way interleaving between its own DIMMs. There can also be board-to-board interleaving if both boards are populated identically. For four-way or board-to-board interleaving to take place, you must follow the DIMM population guidelines set forth later in this section. Both boards are physically identical, but the board in the right-hand bay acts as the primary memory board. This board must always be populated with at least four DIMMs. The board in the left-hand bay acts as the secondary memory board, and need not be populated for the system to run. See Figure 5-2.

Memory Configuration Guidelines
The HP NetServer is equipped with two memory boards. You remove and insert
the board through the front of the server. The boards sit horizontally in two
side-by-side bays, and plug into connectors on the server’s midplane board.
Each memory board supports four-way interleaving between its own DIMMs.
There can also be board-to-board interleaving if both boards are populated
identically. For four-way or board-to-board interleaving to take place, you must
follow the DIMM population guidelines set forth later in this section.
Both boards are physically identical, but the board in the right-hand bay acts as
the primary memory board. This board must always be populated with at least
four DIMMs. The board in the left-hand bay acts as the secondary memory board,
and need not be populated for the system to run. See Figure 5-2.
