Network enabled SCSI interface
First Claim
1. A method of communicating with an SCSI device over a network, the method comprising:
- setting an address at a first computer relating to a file on the SCSI device at a second computer;
receiving a command at the first computer;
reading an address associated with the command;
converting the command to an SCSI command;
determining whether the command relates to the address;
packetizing the SCSI command and transferring the SCSI command over the network to the second computer if the command relates to the address;
unpacketizing the SCSI command at the second computer; and
transferring the SCSI command at the second computer to the SCSI device.

Abstract
A method of communication between a local computer and an SCSI device attached to a remote computer includes receiving a command relating to a file at the remote SCSI device. The local computer creates an SCSI command which is packetized at the local computer and transferred over a network to the remote computer. The remote computer unpacks the command and sends it to the host bus adaptor driver and host bus adaptor controller for the remote device. The remote device then executes the command. Remote SCSI communication is particularly useful in mirroring applications where a complete copy of data is stored at the local location and at the remote location.

10. A method of communicating with a first SCSI device at a first computer and a second SCSI device at a second computer over a network, the method comprising:
-
receiving a mirroring command at the first computer relating to a file on the first SCSI device and the second SCSI device; converting the mirroring command to a first SCSI command and a second SCSI command at the first computer; packetizing the second SCSI command at the first computer; transferring the second SCSI command over the network from the first computer to the second computer; unpacketizing the second SCSI command at the second computer; transferring the first SCSI command at the first computer to the first SCSI device; and transferring the second SCSI command at the second computer to the second SCSI device.
