Handling of data transfer in a LAN-free environment
First Claim
1. A method of handling data transfer, the method comprising:
- sending data from at least one client partition of a first server to at least one partition of a LAN-free server through a Local Area Network (LAN) on a TCP/IP protocol, wherein the sending comprises;
transmitting the data from a first virtual adapter through a virtual LAN to a second virtual adapter; and
transmitting, by the second virtual adapter, the data to a LAN-free storage agent comprising a LAN-SAN Application Programming Interface (API);
converting, by using the LAN-SAN API, the sent data from the TCP/IP protocol into Fibre Channel protocol, wherein the API acts as a gateway; and
sending the converted data to a tape library of a Storage Area Network (SAN) through at least one Fibre Channel card, wherein SAN tape sharing is performed between client partitions via virtualization by sharing Fibre Channel cards coupled to the SAN which is coupled to the tape library, wherein Fibre Channel signaling is configurable to communicate via at least fibre-optic cables, and wherein the Fibre Channel protocol is a transport protocol that predominantly transports small computer system interface (SCSI) commands over Fibre Channel networks,wherein the data transfer is performed in a LAN-free environment, wherein the LAN-free environment comprises;
the SAN having at least one tape library;
the LAN-free server having the at least one partition; and
the first server having the at least one client partition, wherein the LAN-free server further has the at least one Fibre Channel card shared with the at least one client partition.

Abstract
There is disclosed a method, system and computer readable medium for transferring data in a LAN-free environment, in particular for a tape backup or restore operation. Data of a client partition of a first server is sent to a partition of a LAN-free server through the Local Area Network (LAN). The data sent is then converted from TCP/IP protocol to Fiber Channel protocol. The converted data is sent to a Storage Area Network (SAN) through a Fiber Channel card and finally to a tape library. An advantage is thus to mutualize and virtualize resources, in particular Fiber Channel cards. Storage Area Network tape drives are shared using such host bus adapter cards. Certain embodiments avoid the reconfiguration of Storage Area Network tape drives when the client partition moves to a new hardware.

1. A method of handling data transfer, the method comprising:
-
sending data from at least one client partition of a first server to at least one partition of a LAN-free server through a Local Area Network (LAN) on a TCP/IP protocol, wherein the sending comprises;
transmitting the data from a first virtual adapter through a virtual LAN to a second virtual adapter; and
transmitting, by the second virtual adapter, the data to a LAN-free storage agent comprising a LAN-SAN Application Programming Interface (API);converting, by using the LAN-SAN API, the sent data from the TCP/IP protocol into Fibre Channel protocol, wherein the API acts as a gateway; and sending the converted data to a tape library of a Storage Area Network (SAN) through at least one Fibre Channel card, wherein SAN tape sharing is performed between client partitions via virtualization by sharing Fibre Channel cards coupled to the SAN which is coupled to the tape library, wherein Fibre Channel signaling is configurable to communicate via at least fibre-optic cables, and wherein the Fibre Channel protocol is a transport protocol that predominantly transports small computer system interface (SCSI) commands over Fibre Channel networks, wherein the data transfer is performed in a LAN-free environment, wherein the LAN-free environment comprises;
the SAN having at least one tape library;
the LAN-free server having the at least one partition; and
the first server having the at least one client partition, wherein the LAN-free server further has the at least one Fibre Channel card shared with the at least one client partition.- View Dependent Claims (2, 3)
