SAS Compliance Test Presentation Page 2
Serial Attached SCSISmall Computer Serial Interconnect (SCSI) just got a whole lot smaller, faster & more versatile.
•Performance – Gen 1 at 300MBytes/sec per lane
•Scalability – Multi-port, long cables, up to 1.2GBytes/sec
•Reliability and Availability – Secondary failover, P2P
•Flexibility – Supports SAS & SATA drives and SCSI SW

Agilent’s solution is based on the 2005 version of the standard and directly leverages the UNH-IOL SAS
test suite!!!
SAS Compliance Test Presentation Page 9
N5412A is modeled after the industry standard
•UNH-IOL SAS Test Suite is the industry standard.
•Interoperability testing starts at the PHY layer.
•Our solution is complete:
• Minimum of a 10GHz real-time scope
• Reference test loads and connectivity as per the specification
• Provide common tests and algorithms to the UNH-IOL solution
SAS Compliance Test Presentation Page 10
Product DefinitionThe N5412A SAS Electrical Compliance Test application:
•Supports Gen 1(1.5Gbps) and Gen 2(3Gbps) data rates
•Supports the IT, CT Transmit (TX) interfaces and the IR, CR Far-end Transmit (TX) interfaces
•Provides automated 81134A stimulus for OOB signal tests
•REQUIRES that the PHY (DUT) be able to generate CJTPAT, the Compliance Jitter Test Pattern, for testing
•Additionally, Agilent will provide the most common x2 internal drive/host test fixture (Zero-Length Test Load), Transient Test Fixture and Transmitter Compliance Transfer Function (TCTF) for the IT compliance point testing.

Simplistic Single-Port Server ConfigurationA SATA host is analogous to a SAS initiator device; a SATA
device is analogous to a SAS target device. Compliance is defined at the connectors for both buses.
Connector Topology
SATA x1 connector receptacle
SAS Host: SFF-8482 receptacle
SAS Device: SFF-8482 receptacle
SAS Compliance Test Presentation Page 18
Simplistic 4-Port Server ConfigurationA 4-port SAS controller (host bus adapter, usually PCI-X or
PCIe to SAS) will have an internal x4 connector, and will fan out to four individual x1 connectors on SATA or SAS drives. In this case, only the primary port will be used and the secondary port remains unused.
Connector Topology
SAS Host: SFF-8484 receptacle
SAS Device: SFF-8482 receptacle

SAS Test Fixture Requirements
In general, SAS compliance testing will require:
•An adapter from the SAS connector to SMA
•A TCTF (omitted for ZLTL tests)
•A termination network (provided by scope 50-ohm terminations OR Transient Test Circuit)
