Abstract
Drive information related to data storage drives may be exchanged or communicated among switches and hosts to allow the switches and hosts access to the data storage drives. For example, each of the hosts may provide and maintain a storage stack to access data storage on storage drives operably coupled thereto and data storage drives operably coupled to other hosts.
Claims20
A system comprising:
- a plurality of switches, each operably couplable to one or more data storage drives;
- and
- a plurality of hosts, each host operably coupled to one or more data storage drives via a switch and comprising a processor configured to:
- maintain a storage stack to access data storage on the one or more storage drives operably coupled to the host,
- in response to operably coupling a new data storage drive to the switch, add new drive information into the storage stack, and
- communicate the new drive information to the other hosts to allow the other hosts to access the new data storage drive.

A network comprising:
- a plurality of switches, each operably couplable to one or more data storage drives;
- and
- a plurality of hosts, each host operably coupled to one or more data storage drives via a switch and comprising a processor configured to:
- maintain a storage stack to access data storage on the one or more storage drives operably coupled to the host and the one or more data storage drives operably coupled to the other hosts,
- receive new drive information from another host representative of a new data storage drive being operably to the another host, and
- add the new drive information into the storage stack.

Apparatus comprising:
- a plurality of switches, each operably couplable to one or more data storage drives;
- and
- a plurality of hosts, each host operably coupled to one or more data storage drives via a corresponding switch and comprising a processor configured to:
- provide a storage stack to access data storage on the one or more storage drives operably coupled to the host and the one or more data storage drives operably coupled to the other hosts, and
- pre-allocate resources in the storage stack for each of the one or more data storage drives operably coupled to the other hosts.
