Upcoming Webinar: CXL 1.1 vs. CXL 2.0 – What’s the difference?

1 min read

Join the upcoming webinar: “CXL 1.1 vs. CXL 2.0 – What’s the difference?” airing live on Wednesday, June 15 from 9:00 – 10:00 am PT.

Compute Express Link® (CXL®) is a high-speed interconnect offering coherency and memory semantics using high-bandwidth, low-latency connectivity between host processor and devices such as accelerators, memory buffers, and smart I/O devices. The CXL 1.1 specification introduced and defined the CXL I/O protocol, memory protocol, and coherency interface. The CXL 2.0 specification added support for switching for fan-out to connect to more devices; memory pooling for increased memory utilization efficiency and providing memory capacity on demand; and support for persistent memory.

In this webinar, attendees will:

  • Gain a high-level overview of the CXL 1.1 specification.

  • Learn about the enhancements made in CXL 2.0 focusing on switching, memory pooling, Single Logical Devices (SLD) vs. Multiple Logical Devices (MLD), and fabric management.

  • Explore managed hot-plug, memory QoS telemetry, speculative reads, and security enhancements.

We will be hosting a live Q&A discussion immediately after the webinar to address attendee questions from the presentation.
