Abstract

See full text

Local drive presence is provided for local and remote drives by maintaining a plurality of uninterrupted protocol connections between a plurality of I/O controllers and a plurality of device interfaces through which peripheral bus commands are transmitted. Preferably, the I/O controllers are each housed in a separate server blade and provide each blade with access to the local and remote drives. At each of the device interfaces, rather than attaching an actual storage device, peripheral bus commands received at the device interfaces are serialized and conditionally passed or suppressed to and from the shared drive which is shared amongst the plurality of uninterrupted protocol connections. Preferably, the plurality of uninterrupted protocol connections is maintained such that the shared drives can be simultaneously shared. In one embodiment, the local drives are provided in a media tray which is shared amongst a plurality blades.
