A plurality of SMP modules and an IOP module communicate storage traffic via respective corresponding I/O controllers coupled to respective physical ports of a switch fabric by addressing cells to physical port addresses corresponding to the physical ports. One of the SMPs executes initiator software to partially manage the storage traffic and the IOP executes target software to partially manage the storage traffic. Storage controllers are coupled to the IOP, enabling communication with storage devices, such as disk drives, tape drives, and/or networks of same. Respective network identification registers are included in each of the I/O controller corresponding to the SMP executing the initiator software and the I/O controller corresponding to the IOP. Transport of the storage traffic in accordance with a particular VLAN is enabled by writing a same particular value into each of the network identification registers.

Described herein is a device for glaucoma treatment and monitoring that comprises a combination of an intraocular pressure (IOP) sensor and a glaucoma drainage device. The device comprises an IOP sensor and an inductive antenna mounted within a porous biocompatible material that forms the drainage path. The IOP sensor is mounted in a footplate portion of the device and is mountable in the anterior chamber of an eye. The footplate portion is connected to a body portion that houses the spiral antenna by a neck portion which retains the footplate portion in a suitable position within the anterior chamber. Due to its size, the footplate portion housing the IOP sensor can readily be inserted into the anterior chamber with the body portion housing the spiral antenna located outside of the anterior chamber in a sub-scleral space to disperse the aqueous humour.

An apparatus and method for treating glaucoma and lowering IOP is herein disclosed. A method for draining aqueous includes creating an incision in the sclera, opening a scleral flap, and inserting a drainage tube between an associated anterior chamber and at least one aqueous vein.

An SAS RAID adapter comprises an input-output processor (IOP) and at least two SAS input-output controllers (IOCs). Wherein SAS links coupled to each of the IOCs form “virtual ports” in order to increase performance and maintain availability. The virtual ports across the at least two IOCs have wide port SAS link capability so as to provide performance enhancements similar to a standard SAS wide port. Even if a single IOC failure occurs, downshifting to N/2 links is provided with degraded aggregated bandwidth (data throughput) instead of a failover and/or system shutdown.

A data storage system includes a controller, a hot spare storage device and a plurality of primary storage devices. The controller utilizes the hot spare storage device to mirror only a subset of each stripe of logical pages written across the data storage array, where the subset includes a logical page determined by a write input/output operation (IOP) policy. In response to receipt of a write IOP, the controller writes a stripe including a plurality of logical data pages and a logical data protection page across the plurality of primary storage devices and mirrors the logical page determined by the write IOP policy on the hot spare storage device. In response to a failure of a storage device among the plurality of primary storage devices, contents of the failed storage device not already mirrored on the hot spare storage device are rebuilt on the hot spare storage device.

An apparatus and method for dynamically enabling and disabling interrupt coalescing in a data processing system. The present invention involves consistently monitoring IO load on an IOP of an IO adapter. The firmware on the IO adapter may have a global variable that stores counters for PCI function registers. Each counter tracks the number of outstanding IOs of a corresponding PCI function register. The counter is incremented whenever a new IO is received and is decremented upon posting the completed message back to the OS. A timer interrupt is generated periodically so that an ISR may be periodically performed. In the ISR, the maximum value stored of each counter seen since last timer interrupt is analyzed. When the maximum value stored is greater than a predetermined threshold value, the interrupt coalescing is enabled.

A method, apparatus and system for restarting an emulated mainframe IOP, such as a failed or hung emulated mainframe IOP within an emulated mainframe commodity computer. The method includes a rescue process that polls a home location for Restart Request information. In response to receiving Restart Request information, the rescue process is configured to shut down the existing emulated mainframe IOP, start a new emulated mainframe IOP, and reset the home location. The Restart Request information can be provided to the home location by the mainframe computer being emulated. Alternatively, the rescue mechanism can use an interface management card instructed to restart the commodity computer hosting the failed or hung IOP, e.g., from a maintenance service and/or a maintenance program residing in an active commodity computer coupled to the commodity computers hosting one of several emulated mainframe IOPs.

A controller monitors access frequencies of address ranges mapped to a data storage array. Based on the monitoring, the controller identifies frequently accessed ones of the address ranges that have lower associated wear, for example, those that are read more often than written. In response to the identifying, the controller initiates copying of a dataset associated with the identified address ranges from the data storage array to a spare storage device while refraining from copying other data from the data storage array onto the spare storage device. The controller directs read input/output operations (IOPs) targeting the identified address ranges to be serviced by access to the spare storage device. In response to a failure of a failed storage device among the plurality of primary storage devices, the controller rebuilds contents of the failed storage device on the spare storage device in place of the dataset associated with the identified address ranges.

One embodiment facilitates a write operation in a shingled magnetic recording device. During operation, the system receives, by the storage device, data to be written to the storage device and access-frequency information associated with the data, wherein the storage device includes a plurality of concentric tracks. The system distributes a plurality of spare sector pools among the plurality of concentric tracks. The system selects a track onto which to write the data based on the access-frequency information, wherein data with a highest access-frequency is written to an outer track. The system appends the data at a current write pointer location of the selected track, thereby facilitating an enhanced data placement for subsequent access in the storage device.

A computing system having host computer and an I/O processor (IOP) provides firewall services to the host computer. When the host computer and the IOP are initialized, all of the communication ports are reset to a closed state. Application programs are loaded into memory of the host computer for execution and provide the identity of communication ports to be used by the application. The identity of the requested communication ports are used to instruct the IOP to open the communication port to accept network data packets that use the particular port. When the application terminates operation, the communication ports used by the application are closed to provide dynamic control over communication ports. This process ensures that only ports currently used by applications currently executing within the host computer are open without administrator action.
