Introduction

Open WebUI and Ollama are powerful tools that allow you to create a local chat experience using GPT models. Whether you’re experimenting with natural language understanding or building your own conversational AI, these tools provide a user-friendly interface for interacting with language models. In this guide, we’ll walk you through the installation process step by step.

Ollama is a cutting-edge platform designed to run open-source large language models locally on your machine. It simplifies the complexities involved in deploying and managing these models, making it an attractive choice for researchers, developers, and anyone who wants to experiment with language models1. Ollama provides a user-friendly interface for running large language models (LLMs) locally, specifically on MacOS and Linux (with Windows support on the horizon).

This quick-reference guide provides a definitive, up-to-date list of generally available (GA) Compute Express Link (CXL) servers from major OEMs including Dell, HPE, Lenovo, and Supermicro. It is designed for data center architects, engineers, and IT decision-makers who need to identify and compare server platforms that support CXL 1.1 and CXL 2.0 for memory expansion and pooling.

Compute Express Link (CXL) is an open-standard interconnect that enables high-speed, low-latency communication between processors and attached devices such as accelerators and memory expanders. CXL 2.0 adoption has accelerated significantly since 2025, with all major CPU platforms now supporting it natively and the first hyperscale cloud deployments validated in production.

In this post, I’ll discuss what memory tiering is, why we need it, and how to use the memory tiering feature available in the mainline v5.15 Kernel.

What is Memory Tiering?

With the advent of various new memory types, some systems will have multiple types of memory, e.g. High Bandwidth Memory (HBM), DRAM, Persistent Memory (PMem), CXL and others. The Memory Storage hierarchy should be familiar to you.
