SAS Introduction

SAS (Serial Attached SCSI)

A serial communication standard for direct attached

storage (DAS) devices

Fault tolerant technique utilizing one more physical

path (extra small 7pin). Hence its utilized in critical server applications

SAS vs parallel SCSI

Successor to Parallel SCSI, with higher data transfer speed

Point-to-Point SAS bus vs Multi-drop of SCSI bus

SAS still uses SCSI communication protocol

SAS vs SATA

SAS supports HDD, ODD & other peripherals eg. printers & scanners. SATA follows

ATA command set and supports HDD & ODD only

SAS supports multi-path I/O

SAS is backward compatible with SATA

SAS cable up to 8m vs SATA cable limited to 1m

SCSI

SCSI (Small Computer System Interface)

Another device connection standard which can connect to HDD, ODD and other peripheral

devices

Has been popular on high performance workstations and servers

Many versions with different clock speed and throughput

Unlike PATA, SCSI is multi-drop & can handle multiple transactions at a time

SCA-2

SCA (Single Connector Attachment)

A type of connection for internal cabling of SCSI systems

Hot-Swapping allows seamless replacement of failed drives in RAID system

One plug configuration carrying Signal, Power & Jumper together

Ensures electrical / power integrity
