Installing Additional Memory

6-2

The Prioris ZX 6000MP Series server provides a four-way interleaved

memory system, with a minimum supported memory of 64 MB. Memory is

configured in banks, with each bank containing four interleaves (thus the

term four-way interleaving). The MLB contains Bank 0, with four

interleaves (Interleave 0-3) for a total of eight SIMMs (two SIMMs per

interleave). Memory module 1 contains banks 1, 2, and 3 with interleaves

0 and 1; memory module 2 contains banks 1, 2, and 3 with interleaves 2

and 3.

Refer to the “Memory Interleave Upgrade Path” section listed later in this

chapter.
