Product Overview

The CIARA TITAN GLS645R-G6 combines high-density CPU power with smart design for modern workloads. Supporting dual AMD EPYC processors with up to 500W TDP each and up to 3TB of DDR5 memory across 24 DIMM slots, it’s built to handle complex, multithreaded applications with ease.

A direct liquid cooling (DLC) design helps manage high thermal loads without compromising performance, making it ideal for sustained compute-intensive tasks. With 12 hot-swap NVMe bays, 9 PCIe Gen5 x16 slots, and support for multiple M.2 storage devices, the CIARA TITAN GLS645R-G6 is also ready for rapid data ingest, high-speed networking, and custom accelerator integration.

Whether you’re scaling AI clusters, running real-time simulations, or building out flexible edge-to-core infrastructure, this system gives you the performance headroom, I/O flexibility, and thermal efficiency to move faster and operate smarter.
