Abstract: In one aspect, a method of confirming identity of an entity is disclosed. The method comprises receiving a plurality of items for delivery to an address, obtaining, from the items, information regarding an entity associated with the items and the address, and delivering the items to the address. The method may also comprise identifying an expected identity of the entity, receiving a request to confirm an identity of the entity using third-party identity verification via a user interface, and determining, based on the information regarding the entity, a confidence score for the expected identity. The method may further comprise determining whether the confidence score is greater than or equal to the threshold value and generating a response to the request. The method may additionally comprises displaying the response via the user interface.

Abstract: A system including a memory with arrays, a register, and a port. The memory stores an interrupt service routine (ISR). The arrays store respective fields. The port is connected to initiators of a host device and includes a physical layer (PHY) device and a control module. The PHY device: transfers a first frame between the port and a first initiator; and transfers a second frame between the port and the first or a second initiator. The frames include first and second information including respective world wide name addresses and connection rates. The PHY device: compares the first and second information; if there is not a match, interrupts servicing the first frame; and stores an index value for one of the arrays in the register. The control module, based on the index value, executes the ISR to service the second frame based on the fields in the one of the arrays.

Abstract: A method and system for transferring frames from a storage device to a host system via a controller is provided. The method includes transferring frames from a transport module to a link module; and sending an acknowledgment to the transport module, wherein the link module sends the acknowledgement to the transport module and it appears to the transport module as if the host system sent the acknowledgement. The frames in the controller are tracked by creating a status entry indicating that a new frame is being created; accumulating data flow information, while a connection to transfer the frame is being established by a link module; and updating frame status as frame build is completed, transferred, and acknowledged. The controller includes, a header array in a transport module of the controller, wherein the header array includes plural layers and one of the layers is selected to process a frame.

Abstract: A serial attached small computer systems interface (SAS) module includes a first port with (i) a first physical layer device and (ii) a first port control module. The first physical layer device communicates with a plurality of initiators. The first port control module comprises a first world wide number (WWN) table. The first WWN table comprises connection rates of the plurality of initiators during communication with the first physical layer device. Each of the connection rates is a last connection rate of a respective one of the plurality of initiators.

Abstract: A controller including an interface module and an index module. The interface module is configured to connect devices. The index module is configured to include, in a table stored in memory, an entry for each of the devices. Each entry includes an address field. The index module is configured to: receive a frame of data including an address of one of the devices; compare the address to the address fields associated with the entries in the table; in response to the address matching one of the address fields, access an index value identifying an entry of the table when the address matches one of the address fields; and in response to the address not matching one of the address fields, generate the index value. The index value is used to connect the device associated with the matching one of the address fields with the one of the devices.

Abstract: A method and system for transferring data between a host and a Serial Attached Small Computer Interface (“SAS”) device using a storage controller is provided. The storage controller includes, a World Wide Name (“WWN”) module that includes a table having plural entries, wherein each row includes a WWN address, an initiator tag value field, an input/output counter value that tracks plural commands for a connection. A WWN index value represents the address of a row having plural entries. The method includes, comparing frame elements of incoming frames, including a unique WWN address with the WWN module entries; and if there is a match, updating a counter value for a connection between the storage controller and a device sending frames. The counter value is increased when a command frame is received and decreased when a command is executed and a response is sent to the device.

Abstract: A data storage controller includes a link module that selectively sets an interrupt. A control module is external to the link module that includes N buffers where N is an integer greater than 0. The controller allocates at least one of the N buffers to store world wide name (“WWN”) table data in response to the interrupt. The controller also internally manages the WWN table data.

Abstract: A method and a storage controller for transferring data between a host and a storage device is provided. The storage controller includes, a transport module having a first in first out (“FIFO”) for receiving frames from a link module, wherein the FIFO uses two pointers; the first pointer points to a location of a frame that is received with cyclic redundancy code (“CRC”) and the second pointer points to the frame after the CRC is verified and the frame is acceptable. The method includes, using a first pointer to point to a location when a frame arrives without the CRC; and verifying the CRC and if a frame is acceptable using a second pointer to point to the first pointer location. If a frame is corrupt the first pointer and the second pointer point to a location of a receive pointer.

Abstract: A method and system for arbitrating access to a shared disk controller resource, including a buffer memory of a hard disk controller (HDC). An access cycle with a first cycle duration are disclosed and a first amount of time is allocated to a first accessing unit including an error correction code (ECC) engine, a microprocessor first-in-first-out (FIFO) unit, or a memory refresh/data format data fetch unit. The shared controller resource is accessed using the first accessing unit for a first duration, where the first duration is no greater than the first amount of time. A second amount of time and an unused portion of the first amount of time is allocated to a second accessing unit such as a disk formatter. Arbitration limit registers may be used to specify the number of HDC clock cycles per access cycle available to an accessing unit during which it can access the buffer memory. A global arbitration limit counter may be used to keep track of the duration of the accessing units.
