ABSTRACT:
A blade enclosure is provided which may accommodate a first configuration which includes integrated drive enclosure blades (I-DEBs) or a second configuration which includes I-DEBs and non-integrated or switched DEBs (S-DEBs). Each I-DEB includes a pair of redundant RAID controllers, each having two configurable ports. In the first configuration, all four ports are configured as host adapter (HA) ports through which data is exchanged with server blades. In the second configuration, one port of each RAID controller is configured as an HA port, through which data is exchanged with server blades, and the other port of each RAID controller is configured as a device adapter (DA) port, through which data may be exchanged with the S-DEB. Zones may also be established to separate traffic between the servers and the I-DEB from traffic between the I-DES and the S-DEB.
