Teledyne LeCroy Extends Lead in 24G SAS with Support for Microsemi Dynamic Channel Multiplexing Storage Aggregation

SANTA CLARA, Calif., Aug. 8, 2018 /PRNewswire/ -- Flash Memory Summit 2018 -- Teledyne LeCroy, the worldwide leader in protocol test solutions, has added support for Dynamic Channel Multiplexing (DCM) from Microsemi Corporation, a wholly owned subsidiary of Microchip Technology Inc., to the Sierra T244 Serial Attached SCSI 4.0 (SAS) analyzer product line. This announcement follows several major milestones by Teledyne LeCroy in the 24G SAS arena including the introduction of the first 24G SAS analyzer, jammer and exerciser system. Now, with the industry's first DCM analysis capability, Teledyne LeCroy has assembled the most complete line of protocol layer test tools for storage vendors targeting 24G SAS development.

Designed to increase storage performance by improving 24G link utilization, Microsemi DCM technology 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.

"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."

"DCM is a unique approach to boosting throughput and will require careful testing," said Joe Mendolia, vice president of marketing at Teledyne LeCroy's Protocol Solutions Group. "Storage and server OEMs who design DCM into their product offerings will immediately benefit from this new analysis capability, which works off-the-shelf with our existing T244 analyzer platform and gives users complete visibility into DCM storage transfers."

Microsemi DCM technology is built upon 24G SAS and takes full advantage of the improvements in the 24G SAS architecture including persistent connections, forward error correction (FEC) and dynamic transmitter training. Storage OEMs using DCM components to aggregate throughput within the SAS fabric will also find it necessary to test all the new features of 24G SAS. This verification effort will be simplified for users of Teledyne LeCroy's Sierra T244 protocol analyzer, which can automatically detect, capture, and analyze both DCM or standard SAS-4 protocol traffic with a single, cost-effective test platform.


The Sierra T244 platform began shipping in January 2017 and the DCM option is available now for immediate shipment.
