SAS Sierra T244

SAS Sierra T244

The Sierra T244 is a SAS 4.0 protocol analyzer designed to non-intrusively capture up to four 24 Gb/s SAS logical links providing unmatched analysis and debug capabilities for developers working on next generation storage systems, devices and software.

Designed for the SAS 4.0 (24 Gb/s) standard, the Sierra T244 provides the most accurate capture, display and analysis of the next generation SAS protocol. Featuring the industry's highest-fidelity probe design, the Sierra T244 seamlessly locks on 24G signaling without distorting the dynamic link training sequence. For comprehensive testing and verification of components, backplanes and subsystems, the Sierra platform delivers true end-to-end visibility to help ensure SAS 4.0 performance and reliability.

The Sierra T244 features custom probe technology known as T.A.P.4™ (Transparent Acquisition Probing) which has been field-proven in Teledyne LeCroy's 32Gb/s Fibre Channel and PCIe 4.0 analyzer platforms. Leveraging this cutting-edge analog front-end, the T244 provides a robust analysis platform well suited for both silicon bring-up, as well as multi-vendor interoperability testing. The T.A.P.4 probe design sets the standard for accuracy by seamlessly capturing and analyzing the critical link initialization and speed negotiation sequence. Designed to operate transparently, the Sierra passes signals that are nearly identical to the original DUT signaling. This ensures the system-under-test behaves consistently while the Sierra records the 24 Gb/s link training coefficients without distorting the dynamic equalization process.
