How to Upgrade an OpenMetal Medium v4 to Enable TDX

Q: How do I upgrade an existing OpenMetal Medium v4 server to enable TDX?

Upgrading an existing OpenMetal Medium v4 to enable TDX requires scheduling a physical RAM replacement through OpenMetal Support — the server’s 8 DIMMs are replaced with 16 x 64 GB DIMMs, followed by BIOS configuration to activate TDX.

The process involves scheduled downtime. OpenMetal Support coordinates the maintenance window, performs the physical swap from the existing 4 x 32 GB DIMMs per socket to 8 x 64 GB DIMMs per socket, and handles the BIOS configuration to enable TDX after the hardware change. Customers do not need to configure BIOS settings independently. Intel SGX also activates as part of the same process — both technologies share the channel-population prerequisite and are enabled together.

Once complete, the server operates as a Medium v4 TDX Edition with 1 TB DDR5-4400, all 16 DIMM slots populated, and hardware-isolated Trust Domain support active. The upgrade also raises aggregate memory bandwidth from approximately 282 GB/s to approximately 563 GB/s as a result of all 8 DDR5 channels per socket becoming active.

If minimizing downtime on an existing deployment is a priority, an alternative is to order a new Medium v4 with 1 TB RAM pre-installed and TDX pre-configured, then migrate workloads to the new server. Contact OpenMetal Support or Sales to discuss the upgrade path, current lead times, and whether ramp pricing applies to your situation.
