Composable Infrastructure for Private Cloud, AI and HPC

The Role of Composable Infrastructure in Modern IT Environments

Composable infrastructure pools compute, storage, networking, and accelerator resources so they can be assigned dynamically to private cloud, AI, HPC, and virtualised workloads through software.

The platform you choose determines how quickly you can provision bare-metal capacity, how consistently you can apply templates and firmware baselines, and whether changing workload demand means manual rebuilds or API-led automation.

As a partner to vendors including HPE, Dell, and Cisco UCS, we specify composable infrastructure against your requirements, so you're not paying for architectural complexity you won't operationalise or short on fabric, management, or resource flexibility for the workloads you need to support.

Meeting the Demands of Modern Data Centres

Modern composable infrastructure is built to handle the demands placed on dynamic workloads, from flexible provisioning to automation and utilisation.

Delivering Infrastructure Flexibility

HPE OneView, Cisco Intersight, and SuperCloud Composer help turn infrastructure resources into pools that can be assigned by policy.

Accelerating Resource Provisioning

Template-based provisioning reduces the time needed to prepare infrastructure for new applications, test environments, and changing workload demand.

Supporting Dynamic Workloads

Software-defined profiles help match resources to workloads without locking capacity into one static design for its full lifecycle.

Automating Infrastructure

APIs and orchestration tools make infrastructure changes repeatable, auditable, and less dependent on manual console work.

Improving Resource Utilisation

Utilisation visibility helps teams reclaim stranded capacity and assign resources where current workloads need them most.

Preparing for Hybrid Cloud

Composable management prepares infrastructure for hybrid cloud by making resource allocation, lifecycle control, and automation more consistent.

Typical Enterprise Environments

Composable infrastructure adapts to different environments, each with distinct workload patterns, automation goals, and resource allocation requirements.


Data Centres

Dynamic resource pools support virtualisation, private cloud, analytics, and high-performance workloads with standardised builds and efficient utilisation.

Software Development

Programmable infrastructure accelerates dev/test, containers, databases, and AI projects where teams need fast provisioning and repeatable environments.

Finance

Flexible infrastructure supports analytics, risk modelling, and private cloud services with automation, governance, and capacity for fluctuating demand.

Healthcare

Resource pools support research, imaging analytics, virtualisation, and clinical platforms while maintaining controlled builds and changing workload priorities.

Media & Entertainment

Composable resources handle rendering, transcoding, asset processing, and production workloads where compute and accelerator demand shifts by project.

AI / HPC Environments

Pooled GPUs, high-memory nodes, storage, and fabric capacity support AI training, simulation, and analytics without permanent infrastructure silos.

Key Considerations When Deploying Composable Infrastructure

Getting these areas right will help your business avoid costly rework and gaps in performance, resilience, security or lifecycle support.


01

Composable Resource Pools

Plan NVMe & NVMe-oF, compute and fabric resources around how pools will be allocated, reassigned and governed.

02

High-Performance Storage Architecture

Confirm High-Performance Compute (HPC) and storage requirements before designing shared resource pools for demanding workloads.

03

Virtualisation

Validate Virtualisation & Private Cloud Platforms for orchestration, workload placement and operational fit before adopting composable infrastructure.

04

Container Platforms & Kubernetes

For Kubernetes Platforms, confirm persistent storage, networking and scaling requirements before placing container workloads on shared resource pools.

05

Infrastructure Automation

Decide how Infrastructure Management & Monitoring will handle templates, provisioning, firmware, alerts and reporting across resource pools.

06

Lifecycle & Vendor Support

Factor Vendor Support & Lifecycle Services into warranty terms, firmware support windows, expansion options and roadmap fit before committing.

Technology Comparison: Composable vs Hyperconverged Infrastructure

Composable and hyperconverged infrastructure give IT teams different ways to allocate resources. Knowing the difference helps you choose the right model for flexibility, scale and management control.

Composable Infrastructure Hyperconverged Infrastructure
Resource model Pools compute, storage and fabric resources so they can be assigned to workloads as needed Packages compute and storage together in cluster nodes managed as an integrated platform
Most suitable workloads Mixed workloads needing flexible bare-metal, virtualised or cloud-like resource allocation Virtualisation and private cloud estates that benefit from standardised nodes and simpler lifecycle management
Scaling behaviour Can allocate resources more flexibly when workload, capacity or performance needs change Scales by adding nodes, which may add compute and storage together even when only one is constrained
Operational priority Infrastructure flexibility, automation, policy control and faster reconfiguration for varied workloads Simpler operations, repeatable deployment, integrated monitoring and reduced management complexity
What it is not built for Smaller or highly standardised estates where added orchestration is not justified Highly varied environments needing independent resource pooling and frequent reconfiguration

composable infrastructure FAQ

How do I choose the right composable infrastructure platform for our data centre?

Choose composable infrastructure by matching workload variability, resource pooling needs, fabric requirements, automation maturity, and data centre operational model at scale.

Composable infrastructure suits organisations that want to separate compute, storage, and networking into shared pools assigned through software rather than fixed server designs. This is most useful where workload demand changes frequently and operational simplicity matters. Use the platform comparison above to narrow the most suitable option for your workload, scale, and support model.

How does composable infrastructure compare with hyperconverged and traditional architectures?

Composable infrastructure pools resources for flexible allocation, while hyperconverged infrastructure tightly combines compute and storage within simpler building blocks at scale.

Composable platforms disaggregate compute, storage, and networking for software-led assignment, while hyperconverged systems scale in node-based increments and traditional three-tier estates remain more manually managed. A clear comparison helps reduce unnecessary complexity and align platform choice to workload and management needs. The platform comparison above shows how the main options differ across performance, scalability, management, and workload fit.

What impact does composable infrastructure have on resource utilisation and workload agility?

Composable infrastructure can improve utilisation and workload agility by allowing compute, storage, and networking resources to be allocated more dynamically.

This is most valuable where workloads change regularly and teams can operate infrastructure through software and APIs rather than physical reconfiguration. In more static estates, the additional flexibility may offer less practical benefit than simpler architecture models.

How do I know if our infrastructure is a good candidate for composable disaggregation?

Composable disaggregation suits environments with variable resource demand, automation maturity, high utilisation targets, and a need to reduce stranded capacity.

A sound assessment should test real workload variability and the team's readiness to manage infrastructure through software-defined orchestration, rather than selecting the model for architectural novelty. Where the fit is right, teams can scale more predictably and reduce management overhead.

Can you support mixed-vendor composable infrastructure deployments?

Yes, mixed-vendor composable infrastructure can be supported when fabric compatibility, orchestration boundaries, hardware pools, and operational ownership are clearly defined.

These environments are typically more complex because composability relies on close integration between hardware, fabric, and orchestration tooling, so cross-vendor flexibility is usually more limited than in other infrastructure categories. Many organisations run composable platforms for suitable new workloads alongside existing infrastructure during phased adoption. For composable infrastructure decisions, speak to our compute experts to assess workload demand, management tooling, and resource pooling suitability.

What fabric, pooling, and orchestration specifications should composable infrastructure meet?

Specify composable infrastructure around fabric bandwidth, resource pooling, orchestration integration, management APIs, firmware control, and workload placement requirements across enterprise estates.

Specifications should confirm interconnect performance for pooled resources and the orchestration capabilities needed to automate allocation through existing management tooling. This matters because the operational value of composable infrastructure depends on both fabric performance and strong software control.
