Mini SAS HD SFF-8644 to SFF-8643 Server Data Cable | 12Gbps SAS 3.0
I. Introduction
The maxmoge MC4443 is a high-performance external-to-internal server data cable designed to connect external SAS devices (e.g., JBOD, disk expansion enclosures) with SFF-8644 Interface to internal RAID/HBA cards with SFF-8643 Interface. It supports the SAS 3.0 (12Gbps) protocol. Featuring an SFF-8644 metal-shielded external connector, an SFF-8643 high-density Mini SAS internal connector, and 30AWG twinaxial shielded cable, it ensures signal integrity and noise immunity for through‑chassis connections.
⚠️ Note: This cable connects external equipment to internal controllers. The SFF-8644 end is for external use (metal housing), and the SFF-8643 end is for internal use (plastic latch). Do not mix them.
