摘要:
A system provides communication between components of a computer data storage system using out-of-band (OOB) signaling. The system includes a plurality of data storage devices having a local controller for directing data flow to each of the plurality of data storage devices. A switch is coupled to the local controller to direct data to the set of the plurality of data storage devices. First and second initiators are coupled to the switch. The first initiator communicates the OOB signals through the switch alternatively to the local controller or to the second initiator.

A user 100 makes an inquiry through a billing institution 103 to a gene analyzing institution 104 retaining gene analysis information, and the billing institution 103 transfers the gene analysis information received from the gene analyzing institution 104 to the user 100 using a routing address that was dynamically set. The gene analysis information is encrypted at the gene analyzing institution 104 in such a way that decryption at the billing institution 103 is infeasible. Since the gene analyzing institution 104 cannot identify the user 100, and the billing institution 103 cannot know the content of the gene analysis information, privacy of the user 100 can thus be protected.
摘要:
Provided are an apparatus, system composed of apparatuses in a chassis, and a method for managing access among a plurality of devices accommodated in a chassis. Setting information by the user on access between a first management unit including at least one device of said plurality of devices and a second management unit including at least one device of said plurality of devices is accepted. The first attribute information is acquired designating at least any one of an instruction issuing function and an instruction receiving function among the functions of said first management unit and the second attribute information designating at least any one of the instruction issuing function and the instruction receiving function among the functions of said second management unit. A determination is made as to whether or not said setting information is consistent with a combination of said first attribute information and said second attribute information. Information is outputted based on a determination result of the determination.
摘要:
A serial SCSI (SAS) storage drive system includes a drive enclosure having a first interface card coupled to one storage controller over a single SAS path and a second interface card coupled to another storage controller over a different single SAS path. At least one disk drive within the enclosure is assigned to the first storage controller and interconnected to the storage controller through the first interface card. At least a second disk drive within the enclosure is assigned to the second storage controller and interconnected to the storage controller through the second interface card. The interface cards are selectively interconnected with each other through a crossover port. In the event of a failure in a storage controller or an interface card, the crossover port may be activated, thereby maintaining access to both sets of disk drives.

摘要:
An apparatus, system, and method are disclosed for updating firmware to a plurality of memory devices residing on disparate controllers wherein each controller includes an identical communication path address. A management module writes a firmware image to a memory device residing on a primary controller. The primary controller, in turn, copies the firmware image to another memory device residing on a secondary controller. In this manner, the apparatus, system, and method may update firmware on a plurality of memory devices. Because the primary controller is tasked with updating the secondary controller, the management module is only aware that the firmware of the primary controller has been updated. In this manner, updating of the firmware on the secondary controller is transparent to the management module.
摘要:
An apparatus, system, and method are disclosed for receiving digital instructions at devices or controllers sharing an identity. A first controller receives a digital instruction instance over a communications medium. The digital instruction instance maybe a firmware instance. The first controller has ownership of the communications medium and shares the communications medium and a common identity with a second controller. An ownership module transfers ownership of the communications medium from the first controller to the second controller. The ownership module may transfer ownership in response to the first controller successfully receiving the digital instruction instance. A request module requests a retransmission of the digital instruction instance, and may request the retransmission in response to the transfer of ownership of the communications medium. The second controller receives the retransmitted digital instruction instance in response to the retransmission request.
