DETAILED DESCRIPTION
Computing devices, such as workstations and servers, need to record and retrieve information and data. The quantity of such data and information can often be quite large. Therefore, the ability to enable higher storage device density for such computing devices is desirable. Providing configuration flexibility to achieve such higher storage device density is also desirable.
Redundancy may be important in some computing device applications where high reliability transfers with low data loss is needed. For example, the ability to provide redundant SAS capability for single storage device configurations in certain server-based environments may be desirable.
An example of an interconnect assembly 10 directed to addressing these challenges is illustrated in FIG. 1. As used herein, the terms “Serial ATA”, “Serial AT Attachment”, and “SATA” are defined as including a computer bus interface and associated hardware and software for connecting host bus adapters to storage devices. The Serial ATA compatibility specification originates from The Serial ATA International Organization (“SATA-IO). As used herein, the terms “Serial Attached SCSI” and “SAS” are defined as including a point-to-point serial protocol, as well as associated hardware and software, that is used to move data to and from storage devices. The T10 technical committee of the International Committee for Information Technology Standards (“INCITS”) currently develops and maintains the SAS protocol.
As used herein, the term “combination connector” is defined as including, but not necessarily being limited to, a connector that provides multiple sets of signals and power. An example includes an SFF-8482 style connector that includes fifteen (15) power pins and two sets of SAS signals (seven (7) pins each) for connection to SAS devices, such as storage devices. Additional examples include an SFF-8639 style connector, an SFF-8680 style connector and/or other custom connector. In at least some other examples, the combination connector may also be compatible with SATA and/or other types of devices.
As used herein, “backplane” is defined as including, but not necessarily being limited to, a printed circuit board (PCB) assembly that splits or routes signals and power from a combination connector to a plurality of individual storage device connectors. As used herein, “storage device” is defined as including, but not necessarily being limited to a device for recording data and information for subsequent retrieval. Examples of storage devices include, but are not limited to, hard disks, optical drives, tape drives, rotating platters, non-volatile semiconductor memories, solid state memories, magnetic bubble memories, floating-gate transistor memories, memristor assemblies, etc. These storage devices may use a variety of types of storage protocols including, without limitation, SAS, SATA, Peripheral Component Interconnect express (“PCIe”), etc.
As used herein, “host controller” is defined as including, but not necessarily being limited to, a device used to transceive (i.e., transmit and receive) data and information signals to and from storage devices. As used herein, “cable assembly” is defined as including, but not necessarily being limited to, a plurality of wires or cables that: (i) transceive signals, (ii) are bound together by sleeves, insulation, conduit, tape, straps, ties, etc., and (iii) terminate on one or both ends by plugs, connectors, sockets, terminals, and/or pins. As used herein, “power bus” and “power cables” are defined as including, but not necessarily being limited to, an assembly or arrangement that supplies power to one or more combination connectors either through a backplane or by direct connection to such combination connector.
