Features:
MiniSAS 36P-26P PCI adapter board (dual port) SFF8087-8088.
Convert the built-in dual Mini SAS SFF-8087 interface to the external SFF-8088 interface.
The SFF-8087 to SFF-8088 internal transfer external card can convert the built-in Mini SAS (SFF-8087) to an external Mini SAS (SFF-8088) interface. For some server users, it can be connected to an external enclosure.
SAS (Serial Attached SCSI) is a new generation of SCSI technology. It is the same as the popular Serial ATA (SATA) hard disk. It uses serial technology to obtain better transmission speed and shorten the connection cable. Improve internal space, etc. SAS is a new interface developed after the parallel SCSI interface. This interface is designed to improve the performance, availability, and expandability of the storage system, and to provide compatibility with SATA hard drives.
SAS interface technology can be 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 and the SATA interface are fully compatible. SATA hard disks can be used directly in the SAS environment. From the interface standard, SATA is a sub-standard of SAS. Therefore, the SAS controller can directly control SATA hard disks. 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 is composed of three types of protocols, and the corresponding protocol is used for data transmission according to different connected devices. Among them, the serial SCSI protocol (SSP) is used to transmit SCSI commands; the SCSI management protocol (SMP) is used to maintain and manage connected devices; and the SATA channel protocol (STP) is used to transfer data between SAS and SATA. Therefore, under the cooperation of these three protocols, SAS can seamlessly integrate with SATA and some SCSI devices.
