10Gtek# 12G Internal Mini SAS HD SFF-8643 to SFF-8643 Cable, with Sideband, 100-Ohm, 0.8-m(2.6ft), 2 Pack
The cable is used for connecting devices with Mini SAS HD (High Density) interfaces, which are commonly found in servers, storage arrays, and other data center equipment.
10Gtek's High Density (HD) MiniSAS SFF-8643 Internal cable assemblies are available for SAS 2.1, 6Gb/s and SAS 3.0, 12Gb/s specification. Both ends of the cable feature Small Form Factor connectors, specifically the SFF-8643 type. These connectors support up to four lanes of SAS (Serial Attached SCSI) or SATA (Serial ATA) traffic, allowing for high-bandwidth connectivity between compatible devices.
Like the external HD MiniSAS, this new connector uses less PCB real estate and allows higher port density for internal hosts and devices. Hybrid versions of these new cables will allow for a smooth transition from 6Gb to 12Gb.
The impedance of 100 Ohms ensures proper signal integrity and minimizes signal degradation over the length of the cable. The specified length of 0.8 meters is relatively short, making it suitable for close-proximity connections within a rack or chassis where space may be limited. Shorter cables also help maintain higher signal quality and reduce potential interference.
This high speed is suitable for demanding applications requiring fast access to large amounts of data, such as in high-performance storage arrays, RAID controllers, or server backplanes.
