CHAPTER 1 General Description
1.1 Standard Features
1.2 Hardware Structure
1.3 System Configuration
This chapter describes the feature and configuration of the MBA3xxxRC.
The HDDs are high performance large capacity 3.5-inch hard disk drives with an embedded Serial Attached
SCSI (SAS) controller.
The interface used to connect the HDDs to the host system complies with ANSI T10/1601-D Serial Attached
SCSI-1.1 (SAS-1.1), which covers items ranging from SAS physical layers to SCSI command protocols.
The high-speed data transfer and long-distance transmission capabilities of SAS technology and the powerful
command set the HDD facilitate creation of high-performance and highly reliable disk subsystems with large
storage capacities.

electronic equipment (RoHS) directive issued by European Union (EU).
(3) SAS Standard
The HDDs are equipped with a serial attached SCSI (SAS) as a host interface.
• Transfer rate: 1.5Gbps, 3.0Gbps
• Number of SAS ports: Two
• Full-duplex (simultaneous bidirectional data transfer) is supported.
