Managing Host Logins To Storage Systems
US Patent:
2008004, Feb 21, 2008
Filed:
Aug 19, 2006
Appl. No.:
11/506313
Inventors:

International Classification:
G06F 15/16
US Classification:
726 11
Abstract:
Embodiments include methods, apparatus, and systems for managing host logins to storage systems. One method of software execution includes applying different management rules to authorized hosts and non-authorized hosts that are accessing a storage device in a storage area network (SAN) in order to prevent one of the non-authorized hosts from prematurely causing one of the authorized hosts to logout from the storage device

International Classification:
G06F 12/00, G06F 13/00
US Classification:
711004000, 711111000
Abstract:
In a tape drive apparatus commonly shared by a plurality of host devices coupled to the tape drive apparatus over a host port, access control is provided. Each host device is identified by a host address. The tape drive apparatus comprises a data transfer unit for transferring data between a loaded tape medium and the tape drive apparatus. A command for registering a host address of one of the plurality of host devices in the tape drive apparatus for the purpose of authorising access is received over a management port. A command comprising data to be stored on the tape medium is received from a requesting host device over the host port. The host address of the requesting host device is derived from the command received over the host port. The host address of the requesting host device is verified against the host address registered in the tape drive apparatus to determine whether or not the requesting host device has access authorisation. The requesting host device is denied access to the data transfer unit when the requesting host device does not have access authorisation.
Tape Mirror Interface
US Patent:
7237056, Jun 26, 2007
Filed:

International Classification:
G06F 12/00
US Classification:
711 4, 711112, 711150, 711162, 711168
Abstract:
A tape mirror interface comprises an input terminal coupled to at least one input node and capable of receiving data transfer requests, a plurality of output terminals coupled to a plurality of tape storage devices, and a control element coupled to the input terminal and plurality of output terminals. The control element presents the plurality of tape storage devices as separate media devices and selectively controls data transfer in a synchronous mode and a split mode. In the synchronous mode, writes to a target tape storage media are mirrored to a mirrored tape storage media. In the split mode, writes are written to tape storage devices independently.

International Classification:
G06F 12/00
US Classification:
711163
Abstract:
Embodiments include methods, apparatus, and systems for managing a storage library with removable media. One method includes providing to an administrative console identification of host computers attempting to access a tape drive in a tape library; determining, from input at the administrative console, access rights for each of the host computers attempting to access the tape drive; and transmitting the access rights to the tape drive in order to configure the tape drive to determine which of the host computers are authorized to access the tape drive.
