Mini SAS HD SFF-8643 to Mini SAS SFF-8087 Left Exit 90°Cable | 12Gbps SAS 3.0
I. Introduction
The maxmoge MC4387L is a high-performance internal server data cable designed to connect RAID/HBA controller cards (SFF-8643) to Mini SAS 4i backplanes or array cards (SFF-8087). It supports the SAS 3.0 (12Gbps) protocol and features SFF-8643 high-density Mini SAS and SFF-8087 Mini SAS connectors with 30AWG twinaxial shielded cable. The left exit 90° connector allows compact routing against the left chassis wall in 1U/2U high-density rackmount servers, ensuring signal integrity and optimal chassis airflow.
⚠️ Note: This is an internal cable. Make sure your controller uses the SFF-8643 interface and your backplane uses the SFF-8087 interface
