Marvel chipset

Marvel is a core logic chipset for EV7 based systems. A systems is build from so called system building blocks (SBBs). It is one of the last Alpha chipsets and the only chipset that supports EV7. EV7 can connect directly to other EV7 chips. Therefore, no central switch is needed (unlike in Wildfire).

The system can consist of up to eigtht 2P or 8P drawers. 2P drawer contains a single dual-processor module. 8P drawer contains up to 4 dual-processor modules.

Four 2P drawers can be connected to create an 8-processor system. Eight 8P drawers can be connected to create a 64-processor system.
