Chapter 1. General description
21
On both systems, each processor core has access to 256 KB of L2 cache and 10 MB of L3
cache. Each processor on a single-chip module (SCM) connects to eight DDR3 memory
DIMM slots; a total of 16 DIMM slots per SCM. Each memory module is a 1066 MHz DIMM,
and is delivered in pairs. Memory features contain two memory DIMMs per feature code;
features range from 4 GB to 32 GB per feature code. See Table 1-17.
Table 1-17 Summary of processor core counts, core frequencies, and L3 cache sizes
1.8 Build to order
You can perform a build-to-order or
a la carte
configuration by using the IBM configurator
for e-business (e-config), where you specify each configuration feature that you want on
the system.
Preferably, begin with one of the available starting configurations, such as the IBM Edition.
These configurations are available at initial system-order time with a starting configuration
that is ready to run as is.
1.9 IBM Edition
IBM Edition is available only as an initial order. If you order an IBM Edition as defined here,
you can qualify for half the initial configuration’s processor core activations at no additional
charge.
The total memory (based on the number of cores) and the quantity and size of disk, SSD
drives, Fibre Channel adapters, or Fibre Channel over Ethernet (FCoE) adapters shipped
with the server are the only features that determine if you are entitled to a processor
activation at no additional charge.
With an IBM Edition for a Power 720, processor activations for the processor card options are
as follows:
3.6 GHz 4-core processor module (FC EPCK) with 2 x FC EPDK (chargeable) and
2 x FC EPEK (no-charge)
3.6 GHz 6-core processor module (FC EPCL) with 3 x FC EPDL (chargeable) and
3 x FC EPEL (no-charge)
3.6 GHz 8-core processor module (FC EPCM) with 4 x FC EPDM (chargeable) and
4 x FC EPEM (no-charge)
