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. SAS Compliance Test Presentation

Market Trends Tek Compliance Test Tek’s solution is based on a 2003 version of the standard and offers no method of connectivity to the DUT! SAS Compliance Test Presentation

Market Trends Agilent Compliance Test Tek Compliance Test 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

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

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.

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

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 SAS Compliance Test Presentation

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) SAS Compliance Test Presentation
