Fabric management system and method

A PCIe fabric is configured to couple a plurality of elements. The PCIe fabric includes a plurality of PCIe subfabrics. A primary master central processing system is configured to couple the plurality of PCIe subfabrics and includes a primary master central processing unit.

A PCIe fabric is configured to couple a plurality of elements. The PCIe fabric includes a plurality of PCIe subfabrics. Each of the plurality of PCIe subfabrics includes a managing central processing unit and a PCIe fabric switch. One or more communication paths is configured to allow communication between the PCIe fabric switch included within each of the plurality of PCIe subfabrics.

A PCIe fabric is configured to couple a plurality of elements. The PCIe fabric includes a plurality of PCIe subfabrics including at least a first PCIe subfabric and a second PCIe subfabric. A primary master central processing system is configured to couple the plurality of PCIe subfabrics and includes a primary master central processing unit. The first PCIe subfabric is configured to enable multipath communication between a first element coupled to the first PCIe subfabric and a second element coupled to the second PCIe subfabric.

A cabling module is cable management system is configured for use within an IT component and includes an internal cable bundle configured for use within the IT component. An external cable termination module is configured to terminate a first end of the internal cable bundle. A cabling module is configured to terminate a second end of the internal cable bundle. A cable management arm is positioned between the external cable termination module and the cabling module and is configured to absorb any slack in the internal cable bundle.

Cable management

An electronic assembly perform data storage operations on behalf of a set of storage processors (SPs). The electronic assembly includes an enclosure, and a set of peripheral component interconnect express (PCIe) switches which installs within the enclosure. The set of PCIe switches is constructed and arranged to connect to the set of SPs while the set of SPs is external to the enclosure. The electronic assembly further includes a set of data storage devices which installs within the enclosure. The set of data storage devices is constructed and arranged to persistently store data on behalf of the set of SPs via PCIe-based communications through the set of PCIe switches.

Provisioning an enclosure with PCIe connectivity and storage devices

A data storage system having a plurality of disk drive sections, each one of the disk drive sections having a plurality of disk drives. Each one of a plurality of secondary SAS expanders is coupled to a corresponding one of the disk drive sections. Each one of the secondary SAS expanders has: (1) a plurality of first ports each one being connected to a corresponding one of the disk drives in the corresponding one of the plurality of disk drive sections coupled thereto; and (2) a second port. A main SAS expander has: (1) a first port; and (2) N second ports, each one of the N second ports of the main expander being connected to the second port of a corresponding one of the plurality of N secondary expanders. A storage processor is coupled to the second port of the main SAS expander.

Expandable data storage system

A chassis having a cover moveable between open and closed positions and circuitry for detecting whether the cover is in the open or the closed position. The circuitry includes a transmitter of optical energy disposed at a fixed position within the chassis for transmitting pulses of optical energy at a predetermined frequency and a receiver for optical energy disposed at a fixed position within the chassis. A reflector is mounted to an inner surface of the cover and is disposed in a path to intercept and then reflect the intercepted transmitted energy to the receiver when the cover is moved to the closed position and being disposed away from the path to prevent the transmitted energy to be intercepted and then reflected to the receiver when the cover is moved to the open position. The detection circuitry indicates whether the cover is in either the open or the closed position selectively in accordance with whether the transmitted energy is reflected to the receiver is above or below a predetermined threshold level and whether at said predetermined frequency.
