Medium v4 vs Large v4 Hosted Private Cloud

Q: How does the Medium v4 Hosted Private Cloud compare to the Large v4 cluster?

The Medium v4 cluster provides 72 cores, 768 GB RAM, and 19.2 TB raw NVMe across three nodes, while the Large v4 cluster provides 96 cores, 1.5 TB RAM, and 38.4 TB raw NVMe, both running OpenStack and Ceph with Day 2 operations included.

The per-node difference drives the cluster gap. Each Medium v4 node contributes 24 cores (Silver 4510 at 2.4/4.1 GHz), 256 GB DDR5-4400, and 1x 6.4 TB NVMe. Each Large v4 node contributes 32 cores (Gold 6526Y at 2.8/3.9 GHz), 512 GB DDR5-5200, and 2x 6.4 TB NVMe. The Large v4 provides 33% more cores per node with a 17% higher base clock, double the memory, and double the Ceph storage pool.

With 3x Ceph replication, the Medium v4 cluster delivers approximately 6.4 TB usable storage vs 12.8 TB on the Large v4. Both clusters deploy in under 45 seconds, include the same Day 2 operations (monitoring, patching, incident response), and run identical OpenStack and Ceph software stacks with full API and Horizon access.

The Medium v4 cluster fits SMB infrastructure, development and staging environments, and organizations with fewer than 30-40 VMs at moderate sizing. The Large v4 cluster suits production SaaS platforms, higher VM density, and workloads that need more per-core performance or confirmed TDX upgrade eligibility.
