Bare metal instances with Oracle Acceleron

Complete control over the stack

Complete control over the stack OCI bare metal instances provide full control over infrastructure, from the operating system to the application layer, without Oracle-installed software. Oracle Acceleron–enabled shapes provide this same level of control while benefiting from improved throughput and efficiency at the infrastructure level—without changing how workloads are deployed or managed.

No agents or hypervisors needed

OCI bare metal instances run directly on dedicated hardware with no hypervisor or management agents installed, eliminating overhead and complexity. Oracle Acceleron further enhances this model by offloading infrastructure functions, allowing more system resources to be dedicated to applications without affecting performance.

Secured within the tenancy

Bare metal instances run within an isolated tenancy, providing strong security boundaries and full control over the environment. With Oracle Acceleron, infrastructure services, such as networking and storage, are handled separately from application workloads, helping enhance isolation and enable line-rate encryption while maintaining consistent performance.

Performance by design

OCI bare metal instances deliver high, consistent performance by running directly on dedicated hardware without virtualization overhead. With Oracle Acceleron–enabled shapes, networking and I/O processing are offloaded to improve throughput and reduce system overhead—helping applications achieve more efficient, predictable performance for demanding workloads.

No noisy neighbors

Bare metal instances provide dedicated resources with no oversubscription of compute, network, or storage, helping ensure workloads aren’t affected by other tenants. Oracle Acceleron further enhances this isolation by separating infrastructure services from application traffic, enabling consistent performance and predictable latency even under heavy loads.

Ideal for HPC workloads

OCI bare metal instances are designed for high performance computing, with low-latency networking, high memory bandwidth, and scalable cluster capabilities. Oracle Acceleron enhances these environments by improving data movement efficiency and reducing communication overhead, helping HPC and distributed workloads scale more efficiently with consistent performance.

Choose the best configuration for each workload

OCI bare metal instances offer a range of configurations designed for different workload requirements, including general-purpose compute as well as storage-optimized and high performance environments. With the Oracle Acceleron family of shapes, including E6 Standard, E6 Dense, X12 Standard, and A4 Standard, the appropriate balance of CPU, memory, storage, and networking can be selected.

Choose Intel, AMD, or Arm CPUs to match workload requirements

OCI provides a broad portfolio of bare metal instances across Intel, AMD, and Ampere Arm-based processors, offering the flexibility to select the architecture that best fits workload requirements. The latest Oracle Acceleron-enhanced shapes span these platforms:

• AMD-based E6 Standard and E6 Dense
• Intel-based X12 Standard
• Ampere-based A4 Standard

Confidential bare metal instances

Users have the option to enable confidential computing on select bare metal instances in select regions. Once enabled, these bare metal instances use AMD's Secure Memory Encryption technology to encrypt data being processed, preventing unauthorized access or modification of the data.

Isolated network virtualization

Help prevent attacks on customer tenancies with isolated network virtualization. A foundational element of Oracle Cloud Infrastructure’s security-first architecture, the design helps stop malware with a custom-designed SmartNIC to isolate and virtualize the network.

Hardware root of trust

Reduce the risk of firmware-based attacks against Oracle Cloud Infrastructure customer tenants with custom-built, hardware-based, root-of-trust-technology designed to wipe and reinstall the firmware every time a new server is provisioned or a new customer tenancy is established.

Oracle Cloud Infrastructure Vault

Centrally manage and maintain control of the encryption keys and secret credentials used to protect enterprise data and access resources. The security for both are stored in Federal Information Processing Standards (FIPS) 140-2, Level 3-certified, hardware security module (HSM).

Choose from popular operating systems

Oracle supports an extensive list of Microsoft Windows Server and enterprise Linux operating systems, including Oracle Linux, CentOS, Ubuntu, and many others. Oracle Autonomous Linux is a free, autonomous operating environment that reduces complexity and human error to deliver increased cost savings, security and availability.
