SFF-8087 to 4 SATA 7PIN, MINI SAS cable 4i to SATA,

Supports 24Gbps bandwidth.

The SFF-8087 interface is mainly used on the MINI SAS 4i array card as an internal SAS cable.

This adapter supports data transmission of four channels of 6Gbps*4Lane, and the transmission rate reaches 24Gbps.

SAS (Serial Attached SCSI) is Serial Attached SCSI. It is a new generation of SCSI technology. It is the same as the popular Serial ATA (SATA) hard disk. Both use serial technology to achieve higher transmission speed, and shorten the connection line. Improve interior space, etc. SAS is a new interface developed after the parallel SCSI interface. This interface is designed to improve the performance, availability and scalability of storage systems, and to provide compatibility with SATA hard drives.

The interface technology of SAS is backward compatible with SATA. Specifically, the compatibility of the two is mainly reflected in the compatibility of the physical layer and the protocol layer. At the physical layer, the SAS interface is fully compatible with the SATA interface, and SATA hard drives can be directly used in the SAS environment. In terms of interface standards, SATA is a sub-standard of SAS, so the SAS controller can directly control SATA hard drives, but SAS However, it cannot be used directly in the SATA environment, because the SATA controller cannot control the SAS hard disk; at the protocol layer, SAS consists of three types of protocols, and the corresponding protocols are used for data transmission according to different connected devices. The Serial SCSI Protocol (SSP) is used to transmit SCSI commands; the SCSI Management Protocol (SMP) is used to maintain and manage the connected devices; the SATA Channel Protocol (STP) is used to transmit data between SAS and SATA. Therefore, under the cooperation of these three protocols, SAS can be seamlessly combined with SATA and some SCSI devices.
