Teledyne LeCroy Extends Lead in 24G SAS with Industry-First Dynamic Channel Multiplexing (DCM) Analysis Capability

New DCM Testing Capability Enables the Verification Process for Sierra T244 Protocol Analyzer Users Implementing DCM.

Santa Clara, CA – WEBWIRE

Flash Memory Summit 2018 - Teledyne LeCroy, Inc., the worldwide leader in protocol test solutions and a business unit of Teledyne Technologies Incorporated (NYSE:TDY), has advanced its leadership in the 24G SAS market with the addition of an industry-first analysis capability for Dynamic Channel Multiplexing (DCM) from Microsemi Corporation.  This new cost-effective testing feature simplifies the DCM verification process for users of Teledyne LeCroy’s Sierra T244 protocol analyzer.  Following several major milestones by Teledyne LeCroy in the 24G SAS arena, including the introduction of the first 24G SAS analyzer, jammer and exerciser system, Teledyne LeCroy has now assembled the most complete line of protocol layer test tools for storage vendors targeting 24G SAS development. 

 “Today’s announcement demonstrates Teledyne LeCroy’s commitment to providing our customers with a full-suite of cost-effective solutions in support of their 24G SAS development,” said Kevin Prusso, vice president of sales and marketing for Teledyne LeCroy’s Protocol Solutions Group.

In collaboration with Microsemi, a wholly owned subsidiary of Microchip Technology Inc., Teledyne LeCroy developed the new DCM testing capabilities to support the efficient deployment of Microsemi DCM technology, which increases storage performance and improves 24G link utilization.  Microsemi DCM technology is built upon 24G SAS and enables storage subsystems to harness the full performance capabilities of PCIe Gen 4 enabled systems by enabling extremely efficient aggregation of transactions to lower speed drives (6G and 12G).  Fully interoperable with existing SAS and SATA infrastructure, DCM can extend the lifecycle of legacy rackmount storage by aggregating throughput within the SAS fabric.

“Storage and server OEMs using Microsemi DCM technology to aggregate throughput within the SAS fabric will require an effective platform to test all the new features DCM provides,” said Joe Mendolia, vice president of marketing at Teledyne LeCroy’s Protocol Solutions Group.  “This verification effort will be greatly simplified for users of Teledyne LeCroy’s Sierra T244 protocol analyzer who can now take advantage of the new DCM test capabilities to automatically detect, capture, and analyze both DCM and standard SAS-4 protocol traffic.”

“Microsemi has collaborated with Teledyne LeCroy to develop test tools for DCM, ensuring our partners can efficiently deploy this innovative technology,” said Pete Hazen, vice president of Microsemi’s Data Center Solutions business unit.  ”24G SAS with DCM removes bottlenecks in storage infrastructure even when utilizing SATA and SAS-3 drives, enabling greater performance and ultimately better storage utilization in the data center.”


The Sierra T244 platform began shipping in January 2017 and the DCM option is available now for immediate shipment.  Engineers and technicians who would like to learn more can contact their regional Sales Engineer at 1-800-909-7211 or 408-653-1262, or  For more information, visit the Teledyne LeCroy protocol analyzer web page ( and select Serial Attached SCSI.
