摘要:
A multi-chip module (MCM) designed using standard die SAS expander components for rapidly designing a customized SAS expander having a predetermined number of ports. A number of standard expander die circuit components are selected and disposed on a MCM design. Each expander die circuit has a predetermined number of internal ports within the MCM and a predetermined number of ports for coupling to SAS devices external to the MCM. An internal fabric is disposed on the MCM and selectively coupled to internal ports of the SAS expanders to provide the desired number of external ports with desired routing therebetween. The internal fabric may be statically configured or dynamically programmed. The internal fabric routing may provide wide port routes as well as standard port connections.

Methods and associated structure for utilizing multiple ports or PHYs comprising a SAS wide port to improve transmission bandwidth utilization for a single large I/O request. In one aspect hereof, a large I/O request is broken into a plurality of smaller I/O requests to be distributed over multiple PHYs or ports of a configured wide SAS port. The number of smaller I/O requests may be any number up to the maximum number of PHYs or ports comprising the SAS wide port. In another aspect hereof, the size of a large I/O request may be compared against a threshold value to determine whether the large request should be broken into smaller requests. The threshold value may be determined in accordance with features and aspects hereof either statically or dynamically based on workloads assigned to, and utilization of, the configured SAS wide port.

Improved methods and structures for testing of SAS components, in situ, in a SAS domain. A first SAS component is adapted to generate stimuli such as error conditions to elicit a response to the error condition from a second SAS component coupled to the first in the intended SAS domain configuration. In one aspect, a SAS device controller generates stimuli applied to a SAS expander coupled thereto and verifies proper response from the SAS expander. In another aspect, a SAS expander generates stimuli applied to a SAS device controller coupled thereto and verifies proper response from the SAS device controller. Stimuli may be generated by custom circuits or firmware/software within the first component. Vendor specific SAS SMP transactions may be used to cause the first component to enter the special verification mode.

Endovascular filter (10) including a plurality of struts (14) with distal ends (18) adapted to anchor the filter to the vessel wall after deployment, such as by having barbs (20), the filter being adapted to be retrieved if desired. Strut distal ends (18) are coated with an antiproliferative agent (40) that inhibits the ingrowth of tissue around the filter, thereby permitting the filter to be retrieved and removed atraumatically after a prolonged period of time, thus extending the useful life of the retrievable filter. Optionally, the proximal end (22) of the filter may also be so coated, or the entire filter.

Systems and methods are provided for automatically configuring ports of devices within an SAS network domain. A domain control element, such as an SAS initiator, is coupled to a plurality of expander devices. The domain control element configures ports of the expander devices by traversing port connections between the expander devices to determine routing attributes of the ports. The domain control element automatically configures the ports to operate according to the routing attributes. In one aspect hereof, an initiator device of the SAS network domain serves as a control element to perform the automated configuration of routing attributes. In another aspect hereof, an expander device serves as a control element to configure routing attributes of the ports.

An apparatus and method comprising at least one intragastric member made of a digestive-resistant or substantially indigestible material that is introduced into a bag located in the gastric lumen of a mammal for the treatment of obesity. One or more intragastric members are loaded into a delivery tube in a partially compacted first configuration and delivered to an overtube. The overtube includes a proximal end, a distal end and a lumen configured to receive the intragastric members in the first configuration for delivery to the bag located in the gastric lumen wherein the intragastric member is expanded to a second configuration. The apparatus further comprises a constraining element engaged with the bag to secure the intragastric member upon delivery into the gastric lumen.
摘要:
The present invention provides a device and method for mitigating performance degradation caused by SATA drives attached to a SAS domain. In one of the embodiments of the present invention, a SATA degradation mitigation device (“SDMD”) is installed between a SAS domain and one or more SATA drives. The SDMD effectively reduces congestion on intermediate links by buffering SATA data and transmitting the data at a rate which is higher than the rate at which the SATA data is received from a drive. Conversely, write data from the SAS domain may be buffered at the SDMD at a higher rate and subsequently sent to the SATA drive at a lower rate. This SATA data buffering and subsequent increase in data rate improves the overall efficiency of a SAS domain storage system by reducing data congestion arising out of low-performance SATA drives clogging the intermediate links.

Systems and methods for analyzing data passing between an SAS/SATA device and a plurality of other devices are presented. A system includes a plurality of physical interfaces configured for passing data between the SAS/SATA device and the other devices. The system also includes a test interface, or test PHY, configured for coupling to the physical interfaces for analysis of the data passing through those physical interfaces. The test PHY may be integrally configured with the SAS/SATA device and may substantially minimize alteration of characteristic impedance caused by external analysis of the data. The system may also include a multiplexer for selectively coupling the PHYs to the test PHY.
