6 Gb/s SAS/SATA AnAlyzer
Finisar?s leading Xgig® Analyzer is the most powerful monitoring and analysis system available for SAS and SATA applications, offering complete visibility into traffic flows with advanced trace and analysis capabilities. This multi-purpose, multi-protocol tool is designed to help users overcome high-speed serial design challenges and accelerate development of today?s Storage Area Networks (SAN) and storage subsystems. Line rates supported include 1.5, 3.0, and 6.0 Gb/s for both SAS and SATA. Finisar?s Xgig SAS/SATA Analyzer is a versatile, state-of-art solution for monitoring and analyzing live traffic employing a chassis-and-blade hardware architecture. This release of the Analyzer supports Finisar?s 6 Gb/s 4-Wide blade with dual mini-SAS 4x receptacles, allowing bidirectional analysis of single and wide-port (up to 4-wide) SAS links. Double-width blades occupy two slots in a 4-slot Xgig chassis 1 and provide 2 GB RAM per port, with a total of 16 GB for the entire blade (8 ports x 2 GB).
COMPREHENSIVE PROTOCOL SUPPORT
In order to assist users in designing leading edge equipment, the Xgig Analyzer provides full line rate monitoring and analysis for SAS-2 at 6 Gb/s, as well as transparently supports all protocol changes introduced, including new multiplexing and Out-of-Band signaling capabilities. The Xgig Analyzer?s SAS-2 multiplexing features include triggering and filtering on all logical links, viewing of separate Logical Link 0 and Logical Link 1, and Xgig Expert analysis of multiplexed traces. The Analyzer also shows SAS/SATA Out-of-Band (OOB) sequences ? low-speed analog signaling patterns used to both reset and set up link properties ? graphically so users can quickly identify OOB-based errors. By capturing the timing of every Data Burst and D.C. Idle on both sides of OOB negotiations, as well as automatically detecting OOB signaling patterns (COMWAKE, COMRESET, COMINIT, and COMSAS, each denoted using a different color), users are able to verify that both the host and device under test are performing OOB signaling as expected.
NON-INTRUSIVE MONITORING
Different applications have different signaling sensitivities. For minimal signal impact, the Xgig Analyzer offers an Analog Passthrough mode which provides a truly passive, high-impedance, low-latency network connection. The Analyzer passes every monitored bit through exactly as received, enabling users to see the same signal as the device under test sees. While this capability has always been part of Xgig Analyzers, Finisar has refined and improved the Xgig 6 Gb/s SAS/SATA Analyzer to address the specific characteristics of these protocols at high speeds. For extended cable lengths, Xgig provides a Digital Passthrough mode to help maintain signal integrity. By decoding the incoming bits and clock and then actively retiming signals as they are encoded for retransmission, longer cable lengths are possible than with Analog Passthrough.
