A storage controller has at least one physical data port for a data network including host processors. The storage controller is programmed to provide a plurality of virtual ports for access to storage, and a virtual switch for routing storage access requests from the physical port to the virtual ports. The virtual ports and the virtual switch are defined by software. The virtual ports appear to the hosts as physical ports in the data network. For example, in a Fiber-Channel network, the virtual ports have World Wide Names (WWNs) and are assigned temporary addresses (S_Ds), and the virtual switch provides a name server identifying the WWNs and S_IDs of the virtual ports. For convenient partitioning of storage among host processors, one or more virtual ports are assigned to each host, and a set of storage volumes are made accessible from each virtual port. A host can access storage at a virtual port only if the virtual port has been assigned to the host. Preferably, storage can be accessed through each virtual port by no more than one assigned host, although a shared volume may be accessible from more than one virtual port. The storage controller may provide a service for reporting to a host the virtual ports through which the host can access storage, and the storage volumes that are accessible to the host through each of the virtual ports.

A storage controller for controling access to data storage has a memory and at least one data port for a data network including host processors. The memory is programmed to define a respective specification for each host processor of a respective subset of the data storage to which access by the host processor is restricted, and each specification is associated with a host identifier stored in the memory. When the storage controller receives a data access request from a host processor, it decodes a host identifier from the data access request, and searches the memory for a host identifier matching the host identifier decoded from the request. Upon finding a match, the respective specification of the respective subset for the host processor is accessed to determine whether or not storage specified by the storage access request is contained in the respective subset. If so, then storage access can continue, and otherwise, storage access is denied. Preferably the host identifier decoded from the request is a temporary address assigned by the network, and also stored in the memory in association with each respective specification is a relatively permanent identifier for the host processor.

The contactless front end routes a near field communication not related to a payment transaction, and not requiring a security function, between the NFC system and host processor without going to or from the SE.

In a data storage subsystem providing data storage to host processors, a process of configuration defines a subset of the data storage that each host may access. A vector specification is a convenient mechanism for specifying a set of storage volumes that a host may access. For example, for each host processor, there is stored in memory of the data storage subsystem a list of contiguous ranges or vectors of the storage volumes that the host may access. To determine whether or not a specified logical volume number is included in the vector, a modulus of the stride of the vector is computed from the difference between the address of the specified logical volume and the beginning address of the vector, and the modulus is compared to zero. To provide a mapping between logical unit numbers specified by the host and the logical volumes, a contiguous range of logical unit numbers may also be specified for each contiguous range or vector of storage volumes. The logical volume number is computed from a specified logical unit number by computing a difference between the specified logical unit number and the beginning logical unit number, multiplying the difference by the stride of the vector to produce a product, and adding the product to the beginning address of the vector.

<heading lvl="0">Abstract of Disclosure< / heading> An integrated suite of services for consumers, service providers and manufacturers in the pharmaceutical industry is disclosed. The present invention utilizes one or more of the NCPDP standard formats and adopts the switch for an integrated system of, for example, instant adjudication of prescriptions, consumer data warehousing and / or incentive rewards for the consumer. A participating consumer with one card, can instantly purchase pharmaceuticals and charge the transaction to a credit card and earn and apply savings dollars redeemable for pharmaceutical purchases. For a participating service provider, instant adjudication and instant validation of consumer eligibility can be performed. Moreover, a service provider may receive messages related to the patient's medications. Significantly, data is recorded for consumers even when consumers make the pharmaceutical purchase with cash. The system includes a unique card issued to participating consumers. The card is adapted to encode conventional credit or debit card information specific to the participating consumer so that the consumer can consummate a transaction for the purchase of pharmaceuticals without possession of an additional credit card. The system further includes a host processor coupled to the point of sale at the service provider through a leased line or public switch network or the like. When a customer performs a pharmaceutical transaction at the point of sale of the service provider, the host processor coordinates any benefits and data with other prescription benefit management systems through messages transmitted and received from any primary or secondary carrier systems. The host processor further is adapted to facilitate real-time adjudication of claims and checks for any dangerous drug-to-drug interactions. The host processor additionally facilitates any financial processing including the accumulation and redemption of any bonus dollars earned by the consumer. Furthermore, since the card used by the consumer can be encoded with credit or debit card information, the host processor determines the desired payment method and performs the actual financial transaction. Even if the transaction at the point of sale is a cash purchase, the consumer may desire to use his unique card for the accrual of bonus dollars. Therefore, data concerning the transaction (i.e., pharmacy number, prescription number, etc.) can be recorded even for transactions conducted with cash.

Still other aspects of the media processing system provide for improved media security due to the isolation of decrypted audio data from the host processor.

An apparent network interface permits one processor such as a processor embedded within a larger processing system (an embedded processor) to communicate to a host processor or other processors and devices on the network to which the embedded processor is attached, using standard network communication mechanisms / protocols such as TCP / IP, NFS, FTP, HTTP, etc. The web server protocol HTTP is particularly useful because it permits the embedded computer to publish a user interface for remote monitoring and remote control using a standard web browser application. The invention provides the host computer with an apparent network interface that appears to be a standard network device, such as an Ethernet interface card. This apparent interface communicates directly with the embedded processor, which appears to be a device on this apparent network. Significant cost savings and performance enhancements are realized by implementing the communication directly over the host computer's peripheral bus rather than using standard network hardware such as Ethernet hardware.

A data management technique for managing accesses to data at a shared storage system includes a filter at the storage system. The filter is coupled to a configuration table, which identifies which of a number of coupled host processors have accesses to each of the resources at the device. During operation, requests received from the host devices are filtered by the filter, and only those requests to resources that the individual host devices have privilege to access are serviced. Advantageously, data security is further enhanced by authenticating each of the requests received by the storage system to verify that the host processor that is represented as forwarding the request is the indicated host processor. In addition, transfers of data between the storage system and the host processor may be validated to ensure that data was not corrupted during the data transfer.

A Pseudo-Ethernet switch has a routing table that uses Ethernet media-access controller (MAC) addresses to route Ethernet packets through a switch fabric between an input port and an output port. However, the input port and output port have Peripheral Component Interconnect Express (PCIE) interfaces that read and write PCI-Express packets to and from host-processor memories. When used in a blade system, host processor boards have PCIE physical links that connect to the PCIE ports on the Pseudo-Ethernet switch. The Pseudo-Ethernet switch does not have Ethernet MAC and Ethernet physical layers, saving considerable hardware. The switch fabric can be a cross-bar switch or can be a shared memory that stores Ethernet packet data embedded in the PCIE packets. Write and read pointers for a buffer storing an Ethernet packet in the shared memory can be passed from input to output port to perform packet switching.

An object is authenticated by transmitting a random number to the object. The object has an integrated circuit chip including a memory and encryption circuitry. The memory stores information defining an encryption scheme preassigned to the object. The encryption circuitry reads the memory, and encrypts the random number according to the encryption scheme defined by the information read from the memory to produce encrypted data. The memory cannot be read from any output of the integrated chip, and the chip is constructed so that it is virtually impossible to recover the information contained in the memory by visual inspection, probing, or disassembly of the chip. The object is authenticated by checking whether the encrypted data is a correct result of encrypting the data using the encryption scheme pressigned to the object. The method can be used in a data processing system to authenticate each message transmitted by a host processor to a data processing device. For example, when a host logs into the data processing device, the data processing device transmits a series of random numbers to the host. The host encrypts the random numbers to produce a series of encrypted data, and the data processing device concurrently encrypts the random numbers to produce a series of encrypted values. The host inserts respective encrypted data into each message, and the data processing device authenticates each message by comparing the encrypted data in the message to a corresponding encrypted value.

A network switch having a shared memory architecture for storing data frames includes configuration registers that are programmable by a host processor to adaptively adjust overflow buffer locations and flow control watermark levels based on monitored network traffic. The host processor allocates shared resources by setting memory configuration registers corresponding to an external memory, where the network switch uses the external memory for storing received data frames, Management Information Base (MIB) counter values, and output port overflow data. The host processor periodically reads the MIB counter values from the external memory, and adjusts flow control watermark levels or the memory configuration registers in the network switch based on rate-based network traffic derived from the MIB counter values. PCI burst transfers between the host processor and the external memory via the network switch ensure that stored data is not lost during reconfiguration of the external memory. The disclosed arrangement enables resources used by the network switch to be adjusted to minimize congestion by borrowing resources from network ports serving idle stations.
