A brick server is a compact computer server module without a chassis that can come in various processor, RAM, I/O, and storage configurations and is designed to fit into rack locations similar to those for blade servers.
Like blade servers, brick servers are intended to fit in multiple numbers into a rack that provides a shared backplane. Blade and brick servers allow more servers to be contained in the same floor space than the more conventional pizza box servers with a chassis. The term, used by Dell and others, suggests that a brick server, when available, will be more brick-like in shape than a blade server.
Dell refers to a brick server as a "super-blade server."
