Abstract
Techniques are provided for performing multi-pass erase. An erase command is received at a storage area network (SAN) switch in a storage area network. The erase command is associated with a block of data on a target device. A virtual initiator is determined for performing the erase command on the block of data. Multiple bit patterns are generated using a multi-pass erase algorithm. The multiple bit patterns are generated for writing over the block of data on the target device. Repeated writes are performed over the block of data using the bit patterns. The block of data is repeatedly overwritten to remove remanence of the block of data on the target device.
