The Hosted Private Cloud Medium v4 is a three-node OpenStack and Ceph cluster built on the same Medium v4 hardware available as a standalone bare metal server. Each node contributes dual Xeon Silver 4510 processors, 256 GB DDR5-4400, and 6.4 TB of Micron 7500 MAX NVMe to a shared compute and storage pool. OpenMetal deploys the cluster in under 45 seconds, handles Day 2 operations (monitoring, patching, incident response), and charges a fixed monthly rate with no per-hour billing, no VMware licensing, and no per-GB egress. The Medium v4 cluster is the entry point for organizations that need their own private cloud without the compute density or cost of the Large v4 tier.
Key Takeaways
- Production-ready in under 45 seconds: OpenMetal’s proprietary automation deploys a fully configured three-node OpenStack + Ceph cluster in under 45 seconds. No manual provisioning, no multi-day setup.
- 72 cores / 144 threads across the cluster: Three nodes of dual Xeon Silver 4510 at 2.4 GHz base / 4.1 GHz turbo provide sufficient VM scheduling capacity for small-to-mid-scale SaaS platforms, development environments, and SMB infrastructure.
- 768 GB aggregate DDR5-4400 memory: 256 GB per node supports moderate VM density, application caching, and OpenStack instance flavors that fit most development and production workloads below enterprise scale.
- 19.2 TB pooled Ceph NVMe storage: Micron 7500 MAX drives across three nodes form a distributed Ceph storage pool with built-in replication. With 3x replication, usable capacity is approximately 6.4 TB. No SAN, no external storage appliances.
- No VMware licensing costs: OpenStack and Ceph are open-source with zero licensing fees. Organizations migrating from VMware eliminate vSphere, vSAN, and vCenter licensing entirely.
- Day 2 operations included: OpenMetal monitors cluster health, handles patching, and provides incident response. Two support tiers: Base (included) covers hardware and cloud software delivery; Assisted Management adds named Account Engineer, 24/7 incident response, and proactive health checks.

Medium v4 Hosted Private Cloud cluster architecture
What OpenMetal Manages (Day 2 Operations)
OpenMetal operates the Hosted Private Cloud as a managed infrastructure layer. The customer controls the cloud (OpenStack API, Horizon dashboard, VM lifecycle), while OpenMetal handles the platform underneath:
- Monitoring: Built-in Day 2 monitoring across all three nodes, covering hardware health, Ceph cluster status, and OpenStack service availability.
- Patching and upgrades: OpenMetal coordinates security patches and OpenStack version upgrades with minimal disruption to running workloads.
- Incident response: Base support covers hardware, provisioning, and cloud software delivery. Assisted Management (additional fee) adds a named Account Engineer, joint cloud health monitoring, 24/7 incident response, monthly proactive health checks, and assisted upgrades.
- Onboarding: Dedicated Account Manager, Account Engineer, and Executive Sponsor. Private Slack channel for engineer-to-engineer support. Optional weekly Google Meet check-ins. Migration planning for workloads moving from VMware, public cloud, or legacy infrastructure.
The customer retains full root-level access to the OpenStack control plane. OpenMetal does not restrict API access, instance flavors, network topology, or storage policies.
OpenStack API and Horizon Access
The Medium v4 Hosted Private Cloud runs a full OpenStack deployment with API-first access. Manage compute, networking, and storage programmatically via the OpenStack API or through the Horizon web dashboard. Supported operations include:
- VM lifecycle (create, resize, migrate, snapshot)
- Live VM migration via Horizon for zero-downtime maintenance
- Neutron networking with VLANs and optional VXLAN overlays
- Security groups and floating IPs
- Custom instance flavors sized to your workload
- S3-compatible object storage via Ceph RADOSGW
No VMware licensing, no vSphere fees, no vCenter charges. Organizations migrating from VMware retain equivalent functionality through OpenStack’s compute, network, and storage APIs without per-socket or per-VM licensing costs.
Ceph Storage Architecture
The three-node cluster pools all Micron 7500 MAX NVMe drives into a distributed Ceph storage layer. Ceph provides:
- Block storage (RBD): Persistent volumes for VMs with configurable replication (default 3x across nodes). Each write is replicated across all three nodes for data durability.
- Object storage (RADOSGW): S3-compatible API for application-level object storage without external services.
- Self-healing: If a drive or node fails, Ceph automatically re-replicates data across remaining OSDs. No manual RAID rebuilds.
With 19.2 TB raw NVMe across three nodes and 3x replication, usable capacity is approximately 6.4 TB. The Micron 7500 MAX drives deliver 1.1M random read IOPS and sub-1ms QoS at 99.9999% per drive, providing consistent performance for Ceph OSD operations. Boot/data isolation on each node keeps Ceph OSD I/O off the OS drives.
For workloads requiring additional storage density, add Storage Medium v4 or Storage Large v4 nodes to the cluster. Additional compute capacity is available by adding Medium v4 or Large v4 compute nodes.
Recommended Workloads
SMB and startup infrastructure
The Medium v4 cluster provides a complete private cloud for small and mid-sized businesses that have outgrown shared hosting or single-server setups but do not yet need the Large v4’s compute density. The 72-core / 768 GB cluster supports 20-40 VMs at moderate sizing (8-16 GB per VM), with Ceph providing replicated storage and OpenStack handling network isolation between environments (production, staging, development). Fixed monthly pricing makes budgeting predictable for organizations with limited ops staff.
Development and staging environments
Provision isolated development and staging environments that mirror production topology without the cost of dedicated per-environment hardware. OpenStack’s project-level isolation keeps environments separated, while the 6.4 TB usable Ceph pool handles application data and database snapshots. The OpenStack API supports infrastructure-as-code workflows with Terraform, Pulumi, and Ansible for consistent environment provisioning.
Managed Kubernetes infrastructure
Deploy Kubernetes on top of OpenStack VMs using the Medium v4 cluster as the control plane and worker pool. The 48 threads per node handle pod scheduling at moderate density, while Ceph RBD provides persistent volumes with automatic replication. OpenMetal’s private VLAN mesh delivers 20 Gbps per node for pod-to-pod east-west traffic. Compatible with Talos, Flatcar, K3s, and upstream Kubernetes. For larger Kubernetes deployments, the Large v4 cluster doubles compute and storage per node.
VMware migration (entry-level)
Replace a small VMware vSphere deployment with OpenStack on dedicated hardware. The Medium v4 cluster provides equivalent VM lifecycle management, live migration, and network isolation without vSphere, vSAN, or vCenter licensing. For organizations with fewer than 30-40 VMs, the Medium v4 cluster eliminates VMware licensing costs while maintaining operational parity. OpenMetal’s onboarding team supports migration planning, and ramp pricing lets you run both environments simultaneously during the transition.
Web application hosting
Host multiple web applications, APIs, and microservices across the cluster with OpenStack managing VM and network lifecycle. The 19.2 TB raw NVMe pool (6.4 TB usable with Ceph replication) handles database storage and application assets, while the 60 Gbps aggregate private mesh supports inter-service communication. Use OpenStack security groups and floating IPs to expose services selectively.
