Processor

The CPU processor is a Freescale PowerPC 8540 operating at 667 MHz .

Memory

SDRAM
Synchronous Dynamic RAM (SDRAM) is used for the storage of uncompressed executable code and data
structures . The SDRAM consists of a 256 MB DDR-1 DIMM in the base module, expandable up to 1 GB . The
DDR-1 interface is 64 bits running at 166-MHz bus speed (333-MHz data rate) .
Buffer memory
Table 1 highlights the amount of QDR SDRAM allocated for buffer memory for all 1-Gb and all 10-Gb data
ports for each of the 6600 series products .

Flash memory
Both 24-port Gigabit products include 256 MB of Compact Flash and 4 MB of MirrorBit Flash . All other 6600
series products include 1 GB of Compact Flash memory as well as 4 MB of MirrorBit Flash . The MirrorBit Flash
is used for initial boot code . The Compact Flash is used for nonvolatile configuration storage ("NVRAM") .
Compressed image storage and the relatively large storage capacity allow multiple configurations and images
to be stored locally to facilitate upgrades and rollbacks during maintenance periods . The Compact Flash card
is removable for future upgrade capability if needed .
Because all application code is executed out of SDRAM, the Compact Flash may be programmed while the
switch is operational; that is, you can download new code onto the Compact Flash during system operation .
The Compact Flash is sized so that a backup copy of an older revision of application code also may be stored .
The system also allows you to hold up to three copies of configuration files, associating them to a particular
Flash image (primary => Config1, secondary => Config2, Active Running session => Config3) .
