The Mini-SAS HD product portfolio is the next generation SAS based storage I/O System that allows for the signal transmission of both SAS 2.1 ( 6 Gb/s per channel) and the proposed SAS 3.0 (12Gb/s per channel) industry standard protocols. The Mini-SAS HD standards Increases linear board density while doubling the maximum per port aggregate bandwidth.
The portfolio offering consists of both internal and External I/O systems (cables and connectors) that meet the product definitions as defined in the SFF-8643 and SFF-8644 standards. External board connectors deliver full 360 degree shielding in single port (1x1) , dual port (1x2) and quad port (1x4) designs. The Internal board connectors are offered in the same sizes with the rugged mounting brackets.
All board connector systems are fully compliant to SAS 2.1 and proposed SAS 3.0 thus allowing customers to seamlessly move from SAS 2.1 to SAS 3.0 without any part number or design changes. Both systems are terminated to the PCB via eye-of-the–needle terminations in a single step process.
The external & internal cables are offered in both 4x (4 channels) and 8x (8 channel) styles for both the SAS 2.1 and the proposed SAS 3.0 signal speeds. External cables feature rugged die cast covers, a metal latch with low actuation force, a durable pull tab and superior cable strain relief.
The internal cables utilize high speed planar raw cable that allows the user to bend the cable at 90 degree transitions will little to no signal degradation. All internal cables also support side band signaling.
FCI’s also offers cables with Mini-SAS connectors on one end and Mini-SAS HD connectors on the other cable end. Further product and technical information, along with 3-D files and Signal integrity models, can be downloaded from the useful links In the sections below.
