2 LeCroy, a worldwide leader in serial data test solutions, creates advanced instruments that drive product innovation by quickly measuring, analyzing and verifying complex electronic signals. With systems available for both physical and protocol layer testing, LeCroy offers a complete solution to meet the high demands of Serial Attached SCSI (SAS) and Serial ATA (SATA) technologies. Each SAS and SATA system is built with the CATC TM Protocol Analyzer System as its foundation for stable and reliable measurements. With interchangeable plug-ins, field upgradeable firmware, and the ability to link multiple analyzers together for higher bandwidth applications, the CATC platform can evolve, as your protocol analysis needs change. The SAS and SATA Solution The LeCroy SAS solutions, built on the CATC 10K platform, include both Tracer analyzers and Trainer exercisers, and can support both SAS and SATA traffic for either 3.0 or 1.5 Gbps speed. The SASTracer analyzer can have up to 4 sets of connectors, for capturing and displaying traffic from either 2- or 4-wide port configurations, or from up to 8 points along a complex topology. You can also cascade multiple systems to provide a synchronized display of SAS traffic across 8 or 16 links. Available as an additional plug-in module, the SASTrainer TM exerciser is capable of transmitting a single link of 3.0 or 1.5 Gbps traffic (either SAS or SATA), while providing one or two recording channels. As a complete solution, the SASTracer/Trainer system gives you the unique ability to record live traffic and then playback the exact data stream using the Trainer. This saves time in setting up the Trainer operations and provides an easy way to recreate problems reported in the field. The SATA Only Solution LeCroy also offers solutions for SATA only. Available with 1, 2, or 4 recording channels, the SATracer 3G analyzer can tap between two 3.0 or 1.5 Gbps SATA links, and supports the SATA-II specification including SATA GEN2X for external connections. Capable of a single lane of 3.0 or 1.5 Gbps traffic, the SATrainer exerciser provides both host and target side emulation. Integrated with the SATracer analyzer, you can convert trace files into a script for the Trainer in order to recreate bus traffic. 2

3 Powerful Display Views Allow for Easy Analysis of Protocol Traffic LeCroy's Tracer analysis software gives you a variety of powerful tools for analyzing and displaying bus traffic. The Tracer software makes it easy for you to view all elements of a command, even if they are spread over several different physical links, helping you understand traffic flow and ensure devices are behaving correctly at the protocol level. The SASTracer analyzer records all the data on the link. Unfiltered SAS traffic contains tens of thousands of frames and primitives, which can make it extremely difficult for you to analyze and discover errors within the data. Within the CATC Trace TM software display, you can preserve the detail, but also have an easy way to view the traffic hierarchically. For instance, you can: Isolate the view to just the transport layer by clicking on the TRANS icon. This narrows down the display to the transport layer of the protocol, where each bi-directional exchange of infomation is represented as a discrete transaction making it easier for you to see the exchange of information between the initiator and target. Decode up to the application layer by selecting the SCSI icon. This decodes the SCSI command layer, and shows the addresses of the devices involved, the tag, the LUN, the type of command plus performance metrics that the software calculates. Although the CATC Trace display is ideal for showing traffic at the logical level, it is often necessary to drill down to the byte level and see traffic across multiple lanes on a common timescale. The Link Tracker TM software display provides this view, and allows you to see the low level primitives and 32-bit data structures in hex, scrambled hex, or decoded with the field names displayed. For more advanced analysis, another view available to you is the Frame Tracker TM software display. This view shows each exchange of information in a separate cell while preserving the spatial relationship of traffic that is moving across multiple links. Within each of these displays, Tooltips pop up to provide you with detailed descriptions of the field, including information about the SAS or SATA specification. At the higher layers, valuable performance metrics are calculated for each operation such as the number of frames in a sequence or the throughput and latency of a command. This helps you identify possible problems at the lower levels. 3

4 The CATC Trace display logically groups all transactions that are part of a SCSI operation. Colors and graphics are used to represent SCSI operations, transactions and frames. The Frame Tracker display gives a high-level view of primitives and frames across multiple links. May be scrolled independently or synchronized with other displays. Displays an absolute time stamp for each event. Where appropriate, a relative time delta is calculated and shown. May be scrolled independently or synchronized with other displays. The Link Tracker display shows all DWORDs on all channels synchronized to a common clock. Tooltips decode SCSI-specific payload information. Simplify analysis of state transitions by viewing traffic across multiple links. 4

5 Powerful Triggering and Filtering As the protocol evolves and moves from prototypes to system level testing, triggering becomes more important since problems from linking devices is more intermittent. The Tracer software provides the ability to select simple triggers on typical events, like out of band signals, SCSI operations, primitives, hashed addresses or SCSI status. Triggers can be set up on almost any sequence of events possible; it supports up to 256 levels or sequential states, with six events per level. It also allows you to isolate the important part of the traffic stream, and when you open the trace, it jumps right to that portion of the trace. LeCroy s Drag and Drop graphical interface makes sophisticated triggering easy. In this example, SASTracer filters out all ALIGN and NOTIFY primitives; If OPEN_ADDRESS is transmitted and OPEN ACCEPT or OPEN REJECT is not received within 1.00ms, then the analyzer (Open Time-out violation) triggers. Comprehensive Traffic Reports and Summaries Our SAS and SATA solutions are more than just data recorders. The real value is in the analysis of the data. The Tracer software generates detailed reports that provide statistics on the occurrence of errors, primitives, frames, commands and other protocol events within the trace. You can evaluate these metrics at a glance or use them to navigate through the recording. The traffic summary can be printed or saved to text with a single keystroke. Click on Register Host-to-Device FIS to automatically jump through each occurrence within the trace. 5

6 Search Results Quickly The advanced search features in the Tracer software helps you quickly find what you want. By using the Quick Search, you can select fields right from the drop down menu, such as Go To Trigger or Event, or directly to a specific marker or time stamp in the trace. The Go To feature provides a simple way to search for SAS or SATA specific items within the trace, such as SSP frames or specific primitives. The advanced Find lets you search on specific SCSI parameters like the Initiator Address or Tag Value of a SCSI operation. Using the Find dialog, you can chose your selection criteria and create a new trace file that represents only the data you seek. OOB (Out of Band) Decoding Level An OOB icon allows the CATC Trace View to show combined OOB scenarios (establishing link, speed negotiation, etc.) in one simplified and integrated view. These scenarios typically occur at power on and after hardware resets as devices initialize and initiate communications. Intelligent search saves you time by only presenting selections that actually occur in the trace. SAS Compliance Verification and Testing Available as part of the SASTrainer exerciser for no additional cost, the Compliance Test Suite (CTS) provides you with a library of scripts for testing initiator, target and expander device compliance. CTS addresses portions of the protocol that establish connections, perform discovery, manage arbitration, as well as perform error recovery at the SSP transport level. In addition, source code is included that allows you to adapt this substantial test bed to create custom scripts for your own specific applications. CTS can help you uncover latent SAS compliance problems before a device or system enters production. Precise control over Out of Band (OOB) burst and interval timing. Connect command: Automatically responds to OOB and speed negotiation to bring up link. Include files: Define primitives and frames once and re-use as you create alternate versions of scripts. Byte-level control over frame header and payload. 6

7 Tracker Command Analyzer Option The SAS/SATATracker Command Analyzer option for the protocol analyzer comprehensively monitors command execution and completion in SAS and SATA storage subsystems. Tracker can monitor up to 10,000 queued operations simultaneously and triggers a recording if any of the commands remain pending for more than the user-defined timeout limit. Timeout problems can cause degradation and can be very difficult to isolate without Tracker. A Comprehensive Solution LeCroy s SAS and SATA solutions provide you with advanced features necessary to ease the development and deployment of SAS and SATA devices.
