Teledyne LeCroy: Next-Gen CXL 2.0 Device Validation Solution
OakGate CD280-G5 tests high-performance, data-intensive CXL memory devices at scale.
This is a Press Release edited by StorageNewsletter.com on October 7, 2024 at 2:00 pmTeledyne LeCroy, Inc. announces the OakGate CD280-G5 CXL validation test solution for PCIe 5.0-based Compute Express Link (CXL) memory expansion devices.
This next-gen test solution verifies performance and functionality of CXL 2.0 memory devices, accelerating their time-to-market while ensuring high reliability.
Meeting demands of AI and big data
The rise of AI and big data is driving the shift towards heterogeneous computing, where multiple processors work in parallel to process vast amounts of data. CXL, an open standard interconnect supported by PCIe 5.0, enables high-speed, low-latency communication between the host processor and devices such as accelerators, memory buffers, and smart I/O devices, expanding memory capacity and bandwidth to new levels of performance.
Ensuring reliable performance
Functional and performance validation testing is crucial to ensure CXL memory expansion devices meet the CXL standard prior to their release. The OakGate CD280-G5, designed in collaboration with data center architects as well as memory and chipset manufacturers can reliably ensure the intended performance is met.
“Micron’s collaboration with Teledyne LeCroy has helped mature the CXL compliance test ecosystem, in addition to strengthening our own CXL innovation and efforts to deliver the Micron CZ120 memory expansion module, the industry’s first CXL-compliant device in production,” said Siva Makineni, VP of advanced memory solutions at Micron. “Teledyne LeCroy’s CXL validation capabilities are playing an important role in ensuring the quality and compliance of our developing CXL 2.0 solutions. The new CD280-G5 CXL Validation Platform is enabling test and validation of advanced features to ensure broader industry adoption of CXL memory solutions.“
Advanced Features for Comprehensive Testing
The OakGate CD280-G5, equipped with the robust Endeavor validation software, offers a rich collection of validation and visualization capabilities, including:
