Abstract: Embodiments of systems and methods for a storage system are disclosed. More particularly, in certain embodiments desired locations of storage devices may be zeroed out during operation of the storage system and areas that have been zeroed out allocated to store data when commands pertaining to that data are received. Specifically, in one embodiment a distributed RAID system comprising a set of data banks may be provided where each data bank in the set of data banks may execute a background process which zeroes areas of the storage devices of the data bank. When a command pertaining to a logical location is received a zeroed area of the physical storage devices on the data bank may be allocated to store data associated with that logical location.

Abstract: SAS devices provide an OPEN frame when requesting a connection or path to a device. An initiator connection tag value, preferably a 16-bit value, is included in this OPEN frame by the initiator. The initiator connection tag value is included by the target device when the target device reconnects to the initiator. The initiator can use this smaller value in a table lookup to rapidly and easily identify the target device, without requiring decoding of the 64-bit WWN and without waiting to receive a frame containing a tag from the target and decoding that tag.
