這個SAS就是垂直寫入的SATA?
請各位大大解惑 感恩
Serial Attached SCSI
Serial technology - SAS (Serial Attached SCSI) and SATA (Serial ATA) - was introduced to overcome these barriers, delivering greater speed, reliability and scalability. While SATA is designed for desktops, making it a good choice in storage environments requiring configuration simplicity or optimal cost/capacity,
SAS delivers the high performance, scalability and reliability required for bandwidth-hungry mainstream servers and enterprise storage. SAS lends itself to the high-frequency, immediate random data access required for transactional data applications such as online purchases and bank transactions.
Only SAS combines the proven reliability and functionality of SCSI with the performance and design power of serial technology by delivering the following features and capabilities:
Performance - First-generation performance of up to 3Gb/s (300 megabytes/second), wide ports for aggregated bandwidth, full duplex, port aggregation, advanced command queuing and the rich command feature set of SCSI
Scalability - Broad address range to physical devices, long cables with small connectors, and connectivity to external storage systems
Reliability and Availability - Point-to-point connections, multi-initiator capability through expanders for simultaneous access, dual active port support, and redundant paths to targets
Flexibility - Physical and software compatibility with SAS and SATA drives, and backward compatibility with SCSI software and middleware
