摘要： A data storage system includes a storage processor that is configured to perform load and store operations on a storage array on behalf of external devices. The data storage system also includes a controller that isolates communication between the external devices when coupled to the storage array via the storage processor. The controller further maintains a set of registers that store information associated with the data storage system and allows the storage processor to access the register via an I2C bus. The system utilizes an error detection procedure to allow detection of errors in the data transmitted between the controller and the storage processor. During operation, a checksum value is transmitted between the controller and the storage processor using the I2C bus during a register write or read procedure. The controller and the storage processor utilize the checksum value in an error detection procedure to detect the data errors resulting in transmission of the data by the I2C bus.

摘要： A technique controls a network switch having a set of ports. The technique involves configuring the network switch to provide an initial set of communications paths between the ports. The initial set of communications paths defines an initial communications path topology within the network switch. The technique further involves receiving a configuration command which identifies a particular operating mode of the data storage system after configuring the network switch to provide the initial set of communications paths within the network switch. The technique further involves reconfiguring the network switch to provide a new set of communications paths between the ports in response to the configuration command. The new set of communications paths (i) defines a new communications path topology within the network switch, the new communications path topology being different than the initial communications path topology, and (ii) supports the particular operating mode of the data storage system.

摘要： A computerized system includes two storage processors having respective local write caches configured to mirror each other. When a first storage processor becomes unavailable and mirroring of the local write caches is prevented, the computerized system continues to attend to write operations from an external host in a write-back manner by caching write data from the write operations in the local write cache of the second storage processor. In response to a failure of the second storage processor, the computerized system preserves the write data within the local write cache of the second storage processor. Then, upon recovery of the second storage processor from the failure, the computerized system continues to attend to further write operations from the external host in the write-back manner by caching additional write data in the local write cache of the second storage processor while the first storage processor remains unavailable.

摘要： A data storage system includes storage array and a switch that is configurable to create numerous network topologies within the system and to maintain separate communications paths between different computerized devices or networks and the storage array. For example, a user device and a service device, such as a system diagnosis device, can connect to the storage array through the switch. In order to isolate interaction or communication between the user and service devices, the switch can be logically partitioned into two distinct switches to form two distinct, isolated communications paths between the devices and the storage array. With isolated communications pathways established in the switch, in use, the service device is unable to access the user device coupled to the storage array.

摘要： A hot-pluggable I/O annex module of a storage processor assembly includes interface circuitry providing connections to an optional I/O interface module. The I/O annex module includes redundant cooling fans providing cooling airflow to an I/O annex mounting area, main power conversion circuitry for generating main operating power for the interface circuitry, auxiliary power conversion circuitry for generating auxiliary power, a controller for monitoring and controlling the operation of cooling fans; and monitoring circuitry powered by the auxiliary power for monitoring correct operation of the controller and, upon detecting incorrect operation, disabling the main power conversion circuitry. The monitoring circuitry includes a watchdog timer and a latch collectively operative to (i) determine if a controller status signal indicating correct operation of the controller does not toggle for a watch interval, and if so then (ii) enter an operating state in which the main power conversion circuitry is disabled and cannot be re-enabled except by cycling the primary power or removing and reinserting the I/O annex module to/from the storage processor assembly.

摘要： This coke process is a continuous, non-fluidized, operation. This coke process is environmentally friendly due to its closed circuit operation, eliminating coke particulate emissions, hydrocarbon release and water pollution release into the atmosphere. This process utilizes a flash vessel and reactor agitation system in combination to prevent the buildup of coke and eliminate traditional decoking operations. Within the reactor vessel, the mixing and kneading of the hydrocarbons is critical and occurs to promote devolatilization, carbonization and forming of coke. In addition, a significant reduction in steam usage is achieved. Cokes containing low volatile combustible materials are produced. The coke is then cooled and can be safely and easily transported to storage as solid granules or as a slurry.

摘要： A method and apparatus are provided for assigning/obtaining enclosure identification numbers in a distributed switch storage system. The method takes advantage a network topology wherein one port on the switch is always used as a downstream connection (towards a control station) and one always used as an upstream connection (away from the control station). Using single-hop type packets an assignment arbitration protocol ensures that each enclosure is assigned a unique and predictable Enclosure ID.
