What is Scalable Bare Metal (SBM) and how does it work?

What is Scalable Bare Metal (SBM)and how does it work?

Since the dawn of ‘the cloud’, hyperscale cloud providers have been the go-to choice for businesses in need of near-instant scalability. But over time, excessive overheads and performance trade-offs have started to take their toll.

Because of this, hyperscale cloud alternatives like bare metal server hosting have surged in popularity. But while these solutions solve cost and performance pains head on, the vast majority still don’t offer the near-instant scalability of hyperscale cloud environments.

We’ve had countless businesses reach out to us with this dilemma. Multi-vendor approaches go some way to solve the problem, but we knew a more effective solution was possible.

That’s why we developed Scalable Bare Metal (SBM) - a first of its kind product offering combining bare metal power and performance with the flexibility to scale on-demand.

“We expect SBM to become an important part of the servers.com portfolio and a go-to solution for a wide range of customers - from DevOps and infrastructure teams to companies building cloud platforms, SaaS services, high-traffic applications, data processing workloads and gaming projects. Our goal is to deliver a product that provides fast deployment, stable performance and predictable infrastructure on a global scale.”

What is SBM?

SBM is a highly scalable bare metal cloud solution developed by servers.com that addresses the limitations of traditional dedicated server models in terms of flexibility and scalability. With SBM, bare metal servers are spun up in minutes and billed by the hour, offering on-demand compute without compromising performance or resource isolation.

How does SBM work?

SBM is designed for use alongside our Enterprise Bare Metal (EBM) servers as a source of burst capacity.

For most businesses, demand oscillates between stable periods and occasional peaks and troughs. During periods of stability, custom solutions like EBM are ideal. EBM can be optimized to your exact performance requirements to become extremely cost and resource efficient.

However, EBM can’t be scaled on-demand. To cover unexpected or temporary demand spikes you’ll still need a separate source of highly scalable compute. That’s where SBM comes into the picture. While, at the hardware level, SBM is pure bare metal hosting (just like EBM), it’s significantly more scalable with 15-minute provisioning and hourly contracts.

compute needs for SBM and EBM mix

In this way, SBM functions as a ‘bolt on’ to EBM, providing a source of highly scalable bare metal compute that you can tap into as and when you need it.

What makes SBM so scalable is its standardized setup. All SBM servers available for order are pre-provisioned and pre-configured in fixed hardware configurations (known as flavors). This significantly expedites spin up times and allows users to easily grow their infrastructure by adding additional identical nodes with predictable specifications.

There are four base configurations available, designed for varying types of workloads from entry level compute to performance-intensive tasks and large-scale application hosting.

Base configuration CPU RAM Storage
Entry line 4564P 192 GB 2 x 960 GB NVMe
Performance line 9474F 384 GB 2 x 3.84 TB NVMe
Business line 9354P 256 GB 2 x 1.92 TB NVMe
9554P 512 GB 2 x 3.84 TB NVMe

Flavors are based on market trends, customer demand, and vendor benchmarks to create optimal CPU and component combinations.

What about GPU workloads?

SBM and EBM are designed to support CPU, not GPU, workloads. If you also have GPU workloads that need hosting, that’s where our AI Compute (AIC) service comes into play.

AIC offers highly optimized GPU dedicated servers on long-term agreements. And, crucially, it works seamlessly alongside SBM and EBM as part of our hybrid bare metal cloud offering.

By combining these solutions, you can host both GPU and CPU workloads on one private network and avoid the operational complexity of juggling multiple vendors.

Scalable bare metal vs virtual machines (VMs)

Historically, scalable infrastructure has been closely associated with hyperscale cloud services. These services rely on hardware abstraction to create a ‘virtualized’ infrastructure.

Each server is equipped with a hypervisor which splits the server’s resources between multiple VMs. Each VM is then assigned to a different user and the operating system and application placed on top.

hyperscale cloud environment

Virtualized environments are highly scalable because VMs can be duplicated near instantly and assigned resources dynamically. However, the sharing of resources can result in performance tradeoffs from resource contention. And in hyperscale cloud environments, the added flexibility comes with a significant cost overhead.

By contrast, SBM provides on-demand scalability and the full tenant isolation of bare metal, so there’s no hypervisor overhead or risk of resource contention impacting server performance. This makes SBM ideal if you need to scale quickly but also have strict requirements around security, latency and workload predictability.
