ABSTRACT:
In a storage area network (SAN) including a storage device accessible by a remote client, a method is provided. The SAN is configured to allow input/output (I/O) data transport over the SAN between the remote client and the storage device. The method includes establishing a write once read many (WORM) server in the SAN between the storage device and the remote client. Data is received at the WORM server from the remote client. The method further includes appending a digitally signed timestamp to the data, specifying a plurality of locations, and sending the data and the timestamp to the storage device. The data is sent as a series of data over the SAN such that the series of data is written to the storage device at the specified plurality of locations. Future writing of data to the specified plurality of locations is prevented.
