There are four main groups in the storage ecosystem – component manufacturers, subsystem manufacturers, storage interconnect manufacturers and system integrators. The component manufacturers are the people that develop the SATA/SAS controllers – these are companies like Marvell, Vitesse, etc. The subsystem manufacturers are the people that make disk drives – companies like Maxtor, Seagate, etc. The storage interconnect companies can be very broad – they develop HBAs, or Host Bus Adapters. Some of the larger companies in this area are Promise, and even Intel. The final piece of the ecosystem involves the system integrators – the people that are developing chipsets or integrating entire systems. These are companies like Intel, IBM, HP, etc.

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

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

10. Product Definition
The 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.

17. Simplistic Single-Port Server Configuration
A 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

18. Simplistic 4-Port Server Configuration
A 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

19. 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)
