Abstract
In an embodiment, a method can include sending an I/O request from a mainframe to a virtual tape server. The method can further include reading a non-virtual tape file from the virtual tape server to the mainframe over a virtual tape protocol if the I/O request is a read request. The method can further include writing a non-virtual tape file from the mainframe to the virtual tape server over the virtual tape protocol if the I/O request is a write request.
Claims24
A method comprising:
- sending an I/O request from a mainframe to a virtual tape server;
- and
- reading data content, stored as a file on the virtual tape server that is not configured in a tape format, from the virtual tape server to the mainframe over a virtual tape protocol if the I/O request is a read request, and writing data content, to be stored as a file on the virtual tape server that is configured in a tape format, from the mainframe to the virtual tape server over the virtual tape protocol if the I/O request is a write request.
A system comprising:
- a request module configured to send an I/O request from a mainframe to a virtual tape server;
- and
- a read module configured to read data content, stored as a file on the virtual tape server that is not configured in a tape format, from the virtual tape server to the mainframe over a virtual tape protocol if the I/O request is a read request;
- and
- a write module configured to write data content, to be stored as a file on the virtual tape server that is not configured in a tape format, from the mainframe to the virtual tape server over the virtual tape protocol if the I/O request is a write request.
2 more elements
A method comprising:
- responsive to an input/output (I/O) request from a mainframe, sending data content, stored as a file on the virtual tape server that is not configured in a tape format, from a virtual tape server to the mainframe over a virtual tape protocol if the I/O request is a read request, and receiving data content, to be stored as a file on the virtual tape server that is not configured in a tape format, from the mainframe to the virtual tape server over the virtual tape protocol if the I/O request is a write request.
A system comprising:
- a reception module to receive an input/output request from a mainframe;
- and
- a transfer module configured to, responsive to the I/O request from the mainframe, send data content, stored as a file on the virtual tape server that is not configured in a tape format, from a virtual tape server to the mainframe over a virtual tape protocol if the I/O request is a read request, and receive data content, to be stored as a file on the virtual tape server that is not configured in a tape format, from the mainframe to the virtual tape server over the virtual tape protocol if the I/O request is a write request.
