The maxmoge MC8743RA is a high-performance internal server data cable designed to connect SFF-8087 RAID/HBA cards (legacy Mini SAS 4i) to SFF-8643 server backplanes (high-density Mini SAS HD). Supporting the SAS 3.0 (12Gbps) storage standard, this cable allows IT managers to run stable 24/7 configurations across multiple deployment generations while saving framework migration costs. Featuring a space-efficient 90-degree inward right-angle SFF-8643 connector on one end and a straight SFF-8087 connector on the other, it allows clean and unobstructed cable management flush against side walls or backplane boards. Wrapped in premium 30AWG twinaxial shielding material with precise 100-ohm impedance matching, it ensures excellent noise isolation and low insertion loss inside space-constrained 1U/2U server enclosures.
⚠️ Note: This is an internal storage interconnect cable. Prior to installation, always verify that your host controller (HBA/RAID card) uses an SFF-8087 interface and the target disk drive backplane uses an SFF-8643 interface. Do not force orientation as both ends are keyed.
