Memory and Performance
This section describes the type of memory that the extended memory blade server requires and its effect
on performance. The following topics are covered:
•
•
•
•
•
Modern processors are designed to support several generations of memory technology. Cisco's Extended
Memory Technology allows us to replace high-density DIMMs with multiple lower-density DIMMs in
a way that is transparent to the processor and to applications. In some configurations, we are emulating
DIMMs that are not available, such as making four 8-GB DIMMs appear to be a single 32-GB DIMM.
In other cases we can emulate high cost-per-bit DIMMs with multiple low cost-per-bit DIMMs; for
example, making four 4 GB DIMMs emulate a 16 GB DIMM.
