Blade server
Blade servers can contain components such as microprocessors, memory, Ethernet
controllers, and hard disk drives. They receive power, network connection, and
I/O devices (such as DVD drive, keyboard, mouse, video port, USB ports, and a
remote monitoring port) from the BladeCenter S chassis.
A SAS expansion card must be installed in each blade server that will access the
integrated shared storage.
