2-2 General Description

OVERVIEW

NEC Express5800/SIGMABLADE is a modular and multiprocessing system that includes processor,
memory, network connections, optional add-in card slot, and associated electronics, all on a single
mother board called a CPU blade.
The CPU blade, hard disk drive, and other CPU blades are typically installed into a rack-mountable
enclosure that houses multiple CPU blades that share common resources such as cabling, power
supplies, and cooling fans.
This high-density technology reduces the installation space, lowers a total cost of ownership, and
offers increased computing density while ensuring both maximum scalability and ease of
management.
