International Classification:

G06F 1200

US Classification:

711162, 711112, 711114, 707204

Abstract:

A computer system and storage management method for routing data between peer-level storage units. The computer system includes a first storage unit (e. g. , disk drive) and an intelligent controller connected to a storage area network. The intelligent controller is also connected to a second storage unit (e. g. , tape drive). The computer system further includes a host (server and/or workstation) having an application module for generating and transmitting a command to the intelligent controller by way of the storage area network or a system network. In response to the transmitted command, the intelligent controller routes data between the first storage unit and the second storage unit using the storage area network while bypassing the host.

International Classification:

US Classification:

709211

Abstract:

A network provides a method of virtualizing SCSI semantics onto a non-SCSI transport medium. The network includes a plurality of hosts or initiators, a SCSI bus coupled to a plurality of SCSI devices, and a bridge having a non-SCSI front end coupled to the non-SCSI transport medium and a SCSI back end coupled to the SCSI bus. The bridge provides firmware for performing various techniques for virtualizing certain SCSI semantics to ensure support (proper operation) of the plurality of SCSI devices. Examples of SCSI semantics for virtualizing SCSI-2 semantics onto a Fibre Channel interconnect medium (a non-SCSI-2 transport medium) include reserve/release support, unit attention support, the non-tagged command processing support for the initiators. Reserve/release support is virtualized by implementing virtual command responses to the RESERVE and RELEASE SCSI-2 command using a table for storing Fibre Channel world wide names (WWN) and the arbitrated loop address (ALPA) for the plurality of initiators. Virtual unit attention support is achieved by maintaining alist of initiators and status flags to determine when a unit attention condition needs to be sent to a particular initiator.

International Classification:

H03K 190175

US Classification:

326 83

Abstract:

An improved CMOS driver circuit for driving a fast, single-ended, wired-or bus architecture. The driver circuit provides a user-selectable active deassertion assist feature which assists a passive terminator circuit in quickly pulling-up a data or control bus line. The resulting driver circuit provides greater noise immunity to negative voltage transients that result from impedance mismatches caused by poor cable design configurations.

H05K 7/14

Abstract:

A module connectivity device includes a stationary pivot plenum, a number of rocker-arm assemblies movably coupled to the stationary pivot plenum in which the rocker-arm assemblies move between an open position and a closed position, and a number of module connectors movably coupled to the rocker-arm assemblies, in which the module connectors move between a disengaged position and an engaged position with respect to the connectors on system modules. A module connectivity system includes a number of rocker-arm assemblies and a number of module connectors movably coupled to the number of rocker-arm assemblies. The system also includes a module connectivity manager to manage the connectivity of the module connectors.
