串行连接 SCSI(SAS)

串行连接 SCSI(SAS)数据传输技术可在存储器之间传输数据。 SAS 取决于点对点串行协议,替代了数据中心、工作站和服务器中常用的并行 SCSI 总线技术。 该技术以串行传输方案为基础,并使用嵌入式时钟技术和 8b/10b 数据编码方案。

SAS 技术目前已经进入第二代, 称为 SAS-2。它的数据传输速率高达 6Gb/s,优于上一代技术。 上一代技术 SAS-1 仅能提供 3Gb/s 的速率。SAS 的独特之处是,它可以向后兼容串行 ATA(SATA)存储器。 SATA 器件可连接至 SAS 背板,但 SAS 驱动器可能无法与 SATA 背板连接。

国际信息技术标准委员会(INCITS)的技术委员会 T10 负责制定和维护 SAS 协议和物理层,而 SCSI 商会(SCSITA)推动了技术发展。 是德是 T10 和 SCSITA 的活跃成员和贡献者,一直以来都在积极参与研讨会和规范制定。 您在此找到的这些资源将使您概括地认识 SAS 设计,帮助您了解最新的测量技术及讲解设计和调试方法。
