Best Workloads for the OpenMetal XXL v4 Server

Q: What workloads is the OpenMetal XXL v4 best suited for?

The OpenMetal XXL v4 is best suited for workloads that require sustained access to a large memory pool on dedicated hardware: high-memory databases, large Kubernetes clusters, in-memory analytics, blockchain archive nodes, and CPU-based ML inference.

High-concurrency OLTP databases (PostgreSQL, MySQL, SQL Server, Oracle) running large datasets fully in-memory eliminate disk I/O as a bottleneck. The 64C/128T core count handles concurrent query execution, and ECC memory ensures data integrity for financial and regulated data. For multi-tenant virtualization on Proxmox or KVM, the 2TB pool supports 50–100+ VMs without memory overcommit pressure.

Blockchain infrastructure benefits from the NVMe capacity and TDX: full Ethereum archive nodes and high-volume RPC endpoints use the 38.4TB array (expandable to 24 bays), while validator nodes running in TDX trust domains keep signing keys isolated from co-located software.

CPU-based ML inference using Intel AMX and AVX-512 handles medium-scale transformer inference and embedding generation without GPU costs. The 2TB memory pool keeps large model weights loaded in RAM. For training or large-scale inference, OpenMetal’s GPU servers are the recommended platform.
