Physical Interconnection
InfiniBand uses copper CX4 cable for SDR and DDR rates — also commonly used to connect SAS (Serial Attached SCSI) HBAs to external (SAS) disk arrays. With SAS, this is known as an SFF-8470 connector, and is referred to as an "InfiniBand-style" Connector. The latest connectors used with QDR and FDR are QSFP (Quad SFP) and can be copper or fiber, depending on the length required.

Famous quotes containing the word physical:
“[In early adolescence] she becomes acutely aware of herself as a being perceived by others, judged by others, though she herself is the harshest judge, quick to list her physical flaws, quick to undervalue and under-rate herself not only in terms of physical appearance but across a wide range of talents, capacities and even social status, whereas boys of the same age will cite their abilities, their talents and their social status pretty accurately.”
—Terri Apter (20th century)
