Blade Servers
- is similar to a rack server, but it’s smaller and sometimes only contains a CPU, memory, and network controllers
- some blade servers contain storage drives, but they can be configured to use network storage such as a storage area network (SAN) or a network-attached storage (NAS) device
Introduction
Instead of being installed in a rack, blade servers are installed in server bays. This structure allows for more servers to be installed in a smaller area. For example, you might only be able to install 10 rack servers in a rack, but 20 blade servers could fit into blade bays. The blade encasing can still be mounted into a rack, but you can fit more blade servers into the same space compared to rack servers.
Blade servers are often used for large processing clusters, but they also generate a lot of heat. They’re usually more expensive than a rack or tower server, and they require good humidity and cooling infrastructure so that they can run efficiently without causing hardware damage
