PCI Accelerator Cards (PACs) provide additional processing features or performance, but do not add extra physical interfaces to the switch. PACs provide Rapier switches with high-performance hardware-based encryption and/or compression services. PACs have a DMA slave processor, which operates independently of the base system. This processor is responsible for the transfer of data between the base system and the PAC, and the control of local high-speed encryption and compression data processing devices. This architecture allows data encoding to be performed off-line without involving the base switch processor, thereby maximizing PAC performance while at the same time minimizing impact on the switch.
