The Medium v4 is OpenMetal’s entry-level bare metal server, built on dual 5th Gen Intel Xeon Silver 4510 processors (Sapphire Rapids). It is the first server in the Medium tier, positioned below the Large v4 for workloads that need dedicated hardware without the compute density or storage capacity of the higher tiers. Available as a standalone dedicated server with full root access and IPMI, or as part of a three-node Hosted Private Cloud cluster running OpenStack and Ceph, both on fixed monthly pricing with no shared tenancy.
Key Takeaways
- Cost-effective dedicated entry point: Dual Xeon Silver 4510 processors deliver 24 cores / 48 threads at 2.4 GHz base / 4.1 GHz turbo with enough compute for production databases, container orchestration, and multi-tenant hosting at a lower price point than the Large v4, while maintaining the same no-shared-tenancy guarantee and full IPMI access.
- Boot and data drive isolation: Two dedicated 960 GB SSDs in RAID 1 keep OS I/O completely separate from the 6.4 TB Micron 7500 MAX data drive, eliminating I/O contention that degrades database WAL writes and container overlay performance on commodity providers with shared boot/data volumes.
- 256 GB DDR5-4400 with upgrade headroom: 16 DIMM slots and a 4 TB max capacity provide a path to 512 GB, 1 TB, or beyond without replacing the server. The base 256 GB handles PostgreSQL shared buffers, Redis datasets, and moderate-density VM hosting out of the box.
- 20 Gbps LACP private mesh: Dual 10 Gbps NICs bonded via LACP deliver the same private bandwidth as larger tiers, with all east-west traffic included at no cost for database replication, Ceph OSD synchronization, and Kubernetes pod-to-pod communication.
- 95th-percentile egress billing: Public bandwidth is billed on 95th-percentile burst, not per-GB transfer. Predictable monthly costs without AWS-style egress surprises.
- HIPAA-eligible infrastructure: OpenMetal is HIPAA compliant at the organizational level and offers BAAs. Medium v4 servers deployed in Ashburn and Los Angeles are hosted in HIPAA-compliant facilities operated by the facility provider.

Tell us about your workload and we’ll help you configure the right deployment.
Processor: Intel Xeon Silver 4510 (Sapphire Rapids)
OpenMetal selected the Xeon Silver 4510 for the Medium v4 as the entry point for dual-socket bare metal. At 2.4 GHz base / 4.1 GHz turbo across 12 cores per socket (24 total, 48 threads), the 4510 provides enough per-core performance for latency-sensitive workloads like web serving and moderate database queries, while keeping the TDP at 150W per socket — roughly two-thirds of the Large v4’s Gold 6526Y. Each processor provides 30 MB of L3 cache, 60 MB total across both sockets.
The 4510 belongs to Intel’s 5th Gen Intel Xeon Scalable family (Sapphire Rapids), fabricated on Intel 7. PCIe 5.0 provides high-bandwidth connections to the Micron 7500 MAX NVMe drive and LACP-bonded network adapters 80 PCIe 5.0 lanes per processor. Inter-socket UPI links run at 16 GT/s , supporting NUMA-aware workload placement for database hosting and VM scheduling.
For workload-specific acceleration, the 4510 includes AVX-512 for vectorized floating-point compute. AVX-512 accelerates vectorized database query execution (ClickHouse, PostgreSQL) and scientific workloads. For GPU-class training and inference workloads, OpenMetal offers dedicated A100 and H100 servers in the same facilities.
Memory: 256 GB DDR5-4400
OpenMetal configures the Medium v4 with 256 GB of DDR5-4400 ECC registered memory across the 16 available DIMM slots . DDR5-4400 operates at 4,400 MT/s, delivering 35.2 GB/s per channel. With 8 memory channels per processor and two processors, aggregate memory bandwidth reaches approximately 563 GB/s .
That bandwidth supports memory-throughput-bound workloads at moderate scale: PostgreSQL shared buffers up to 64 GB, Redis datasets, Proxmox or KVM virtual machines at moderate density, and container orchestration with multiple pods competing for memory. The 256 GB base configuration handles most single-application deployments and moderate multi-tenant hosting scenarios without upgrade.
The 16 DIMM slots provide an upgrade path to 512 GB, 1 TB, or beyond without server replacement. Contact OpenMetal to discuss RAM upgrades on deployed servers. ECC is standard across all OpenMetal configurations, catching and correcting single-bit memory errors before they affect running workloads — a requirement for production databases, financial systems, and compliance-sensitive deployments.
Storage: Micron 7500 MAX NVMe
Boot and data isolation
The Medium v4 separates boot and data storage into dedicated drive pools. Two 960 GB SSDs serve as dedicated OS drives in RAID 1, keeping system-level I/O (logging, package management, system monitoring) completely off the data NVMe drive. This is an OpenMetal design decision applied across current-generation servers: boot drive failures do not take down data workloads, and data I/O does not compete with OS operations. For details on boot drive configuration, see the Dual Boot Drives with RAID 1 feature page.
Data drives: Micron 7500 MAX
The Medium v4 ships with 1x 6.4 TB Micron 7500 MAX NVMe SSD (6.4 TB raw capacity). The 7500 MAX uses Micron’s 232-layer 3D TLC NAND with 6-plane architecture and independent wordline read (iWL), connected via PCIe Gen4 x4 (NVMe v2.0b).
| Metric | Micron 7500 MAX (6400 GB) |
|---|---|
| Sequential Read | 7,000 MB/s |
| Sequential Write | 5,900 MB/s |
| Random Read IOPS | 1,100,000 |
| Random Write IOPS | 400,000 |
| Mixed 70/30 IOPS | 650,000 |
| Read Latency (typical) | 70 us |
| Write Latency (typical) | 15 us |
| Read Latency (99th pct) | 80 us |
| Write Latency (99th pct) | 65 us |
| Endurance (TBW) | 35,040 TB |
| DWPD | 3 |
| MTTF | 2,000,000 hours (0-55C) / 2,500,000 hours (0-50C) |
| QoS | Sub-1ms at 99.9999% (6-nines) for 4KB random read up to QD128 |
| Warranty | 5 years |
The chassis supports up to 6 total drives. With 2 boot drives and 1 data drive currently installed, 3 open bays are available for additional NVMe capacity — scaling the Medium v4 to approximately 25.6 TB of NVMe data storage with all bays populated.
Networking
Each Medium v4 ships with dual 10 Gbps NICs, LACP bonded for 20 Gbps aggregate private bandwidth. Hardware lives on customer-specific VLANs, and all private network traffic is included at no additional cost. This is where east-west traffic between servers in the same deployment moves: database replication, Ceph OSD heartbeats, Proxmox corosync and live migration, Kubernetes pod-to-pod communication. For LACP bonding details, see the Dual Uplinks with LACP feature page.
The Medium v4 includes 2 Gbps of public bandwidth with burst capacity up to 40 Gbps. OpenMetal’s base network SLA is 99.96%, with actual performance exceeding 99.99% since 2022 (2026 is also tracking above 99.99%). DDoS protection is included for up to 10 Gbps per IP. Use OpenMetal IPs or bring your own /24 or larger block for direct public internet connectivity.
Egress pricing: 95th-percentile billing, not per-GB transfer
Public egress is billed on 95th-percentile measurement, not per-GB transfer. This is a structural cost advantage over AWS, Azure, and GCP, where egress charges scale linearly with traffic volume. On OpenMetal, a server that bursts to 5 Gbps during a deployment window but averages 1 Gbps pays for the 95th-percentile rate, not for every byte transferred. Additional 1 Gbps public egress is available at $375/month in advance, or billed at 95th percentile for overages in arrears.
Security, Compliance, and Confidential Computing
The Medium v4’s Xeon Silver 4510 supports Intel SGX for application-level memory encryption. SGX creates encrypted enclaves that protect specific application code and data from the host OS, hypervisor, and other processes — useful for key management, certificate signing, and secure computation on sensitive data. The Silver 4510 supports Intel TDX at the hardware level. OpenMetal enables TDX when the server is configured with all DIMM slots fully populated to 1 TB of RAM (16 DIMM slots × 64 GB = 1 TB). Contact OpenMetal to configure a TDX-enabled Medium v4. In the base 256 GB configuration, TDX is not active. For servers with TDX enabled by default, see the XL v4, XXL v4, and XL v4 High Frequency tiers. TME-MK (Total Memory Encryption — Multi-Key) encrypts all DRAM with per-tenant keys.
- AES-NI: Hardware-accelerated AES encryption for TLS termination, disk encryption, and VPN throughput without CPU overhead.
- Boot Guard: Verifies firmware integrity during boot, preventing rootkit injection before the OS loads.
- Control-Flow Enforcement Technology (CET): Hardware-level protection against ROP/JOP attacks.
For a step-by-step guide to enabling SGX on OpenMetal servers, see the Enabling Intel SGX and TDX guide page.

Recommended Workloads
Web hosting and application serving
The Medium v4’s 24 cores at 4.1 GHz turbo, 256 GB DDR5, and boot/data isolation make it a strong fit for hosting multiple web applications, API servers, and application backends. The dedicated boot drives handle OS-level logging and package management while application data and databases use the 6.4 TB Micron 7500 MAX NVMe. IPMI access allows remote OS installs and BIOS configuration without a support ticket. Deploy multiple Medium v4 servers behind a load balancer with the 20 Gbps LACP mesh carrying inter-service traffic at zero cost.
Databases and transaction processing
PostgreSQL, MySQL, and MariaDB workloads benefit from the 4510’s 4.1 GHz turbo for single-threaded query performance and the Micron 7500 MAX’s 70 us read latency for index lookups. The 256 GB RAM supports PostgreSQL shared buffers up to 64 GB with room for OS cache and connection pooling. Boot/data isolation keeps WAL writes on dedicated NVMe, free from OS contention. For larger datasets or higher concurrency, the Large v4 doubles both RAM and storage capacity in the same chassis.
Kubernetes and container orchestration
Run Talos, K3s, or full Kubernetes on bare metal with direct hardware access and no hypervisor overhead. The Medium v4’s 48 threads handle pod scheduling at moderate density, while 256 GB RAM supports etcd datasets and in-memory caching layers. Boot/data isolation means container runtime I/O (image pulls, overlay writes) stays on the boot drives while application data uses the NVMe pool. Three Medium v4 servers connected over the 20 Gbps LACP mesh form a cost-effective production cluster for development environments, staging, and moderate-scale production workloads.
Virtualization and multi-tenant hosting (Proxmox, KVM)
OpenMetal publishes a Proxmox reference architecture for bare metal servers demonstrated by Level1Techs, applicable to Medium v4 deployments for smaller-scale multi-tenant hosting. With 48 threads and 256 GB RAM, the Medium v4 supports 8-16 VMs at moderate density (16-32 GB per VM), with VLAN segmentation between tenants and ZFS or local NVMe for VM storage. IPMI provides full console and BIOS access for Proxmox installation and hardware-level troubleshooting. For higher VM density and double the storage, the Large v4 offers 512 GB RAM and 12.8 TB NVMe.
CI/CD infrastructure
Jenkins, GitLab Runner, Drone, or GitHub Actions self-hosted runners benefit from the Medium v4’s balanced compute and storage for build, test, and artifact stages. The 6.4 TB NVMe handles large repository clones and build artifact caching with 7,000 MB/s sequential read, while 24 cores support parallel build pipelines. Boot/data isolation prevents build I/O from affecting the runner management layer. Fixed monthly pricing makes cost predictable regardless of pipeline volume, unlike per-minute cloud CI pricing.
Blockchain infrastructure
Validator nodes and RPC endpoints that do not require the full storage capacity of the Large v4 fit the Medium v4’s 6.4 TB NVMe (expandable to ~25.6 TB) and 24 cores. The Micron 7500 MAX’s 1.1M random read IOPS handles state lookups and block validation. Fixed monthly pricing avoids cost unpredictability of running blockchain nodes on per-hour cloud instances. Boot/data isolation protects chain state writes from OS activity. For archive nodes requiring larger storage, consider the Large v4 (12.8 TB base) or Storage Large v4 (240 TB HDD + 25.6 TB NVMe cache).

Cloud Comparison: OpenMetal Medium v4 vs AWS m7i
The closest AWS instance family by spec profile is the m7i (general-purpose, Intel Xeon Sapphire Rapids). The m7i.4xlarge (16 vCPUs, 64 GB RAM) is a starting tier comparison, while the m7i.16xlarge (64 vCPUs, 256 GB RAM) matches closer on memory. The Medium v4 provides dedicated hardware with persistent local NVMe and IPMI access that no m7i variant offers.
| Dimension | OpenMetal Medium v4 | AWS m7i.4xlarge |
|---|---|---|
| CPU | 24 physical cores / 48 threads (dedicated) | 16 vCPUs (shared physical host) |
| RAM | 256 GB DDR5-4400 | 64 GB |
| Storage | 6.4 TB NVMe (Micron 7500 MAX, persistent) | EBS only (no instance storage) |
| Tenancy | Single-tenant dedicated hardware | Shared host (dedicated host extra) |
| Egress | 95th-percentile billing, burst to 40 Gbps | Per-GB ($0.09/GB first 10 TB) |
| Pricing Model | Fixed monthly, lock up to 5 years | On-demand hourly, or 1/3-year reserved |
| IPMI | Full IPMI (power, console, BIOS) | Not available |
| Network | 20 Gbps private (LACP), 2 Gbps public | Up to 12.5 Gbps |
| Management | Self-managed or Assisted Management | Self-managed |
Note: A closer RAM match would be the m7i.16xlarge (64 vCPUs, 256 GB RAM) , but that instance over-provisions vCPUs relative to the Medium v4’s 24 physical cores. The structural difference is the billing model: OpenMetal’s fixed monthly rate includes predictable egress, persistent NVMe storage, and IPMI, while AWS costs scale with usage, transfer volume, and commitment term. EBS storage on the m7i adds both cost and latency compared to local NVMe.
When public cloud is the better fit
Public cloud remains a strong choice for event-driven architectures that need scale-to-zero, workloads with deep integration into AWS-native services (Lambda, DynamoDB, SageMaker), and organizations spending under $10,000/month on cloud infrastructure where the operational overhead of managing dedicated hardware may outweigh the cost savings. For organizations spending above $20,000/month on public cloud, OpenMetal’s fixed pricing model typically delivers close to 50% cost reduction.
