Before we start, here’s a brief thought-association game: When you hear the word sustainability, what comes to mind?

You might think green or carbon reduction or zero waste. You might even think cost savings or higher efficiency.

But what about performance? Or optimization? Chances are that those terms won’t be in your initial word cloud. In fact, they’re typically considered to be the things you sacrifice when sustainability is your focus.

The circular data center model is turning those assumed trade-offs into distinct advantages. Just like electric cars have instantaneous, Formula 1-grade torque that’s beyond the capabilities of gas-guzzling combustion engines, circular data centers are better suited for power and speed than their classic “sustainable” hallmarks would lead you to believe. 

Consequently, these new models are challenging all of the crusty, outdated preconceptions we have about what it means to be committed to minimizing your environmental footprint while remaining on the competitive cutting edge.

Accessible hyperscale technology to power today’s workloads

As technological advancements like artificial intelligence (AI) and machine learning (ML) raise the performance bar for server hardware, data center facilities have to work harder to keep up. And as new models like distributed edge computing and cloud-native workloads gain traction, they need to be more responsive and dynamic. They need to upgrade their infrastructure or roll out new equipment at a faster pace than conventional planning and deployment schedules will allow. That process is even more difficult when their options are restricted to off-the-shelf OEM solutions and vendor lock-in.

The circular data center model instead takes a holistic view of hardware—one that favors accessibility, responsive scalability and flexibility. Unlike the wasteful take–use–dispose model that has become the industry default, circularity is all about right-sizing your solution for a specific use case, space, time and budget.

That’s how the circular approach enables data center operators, service providers and enterprises to scale and adapt at the pace of business. Done right, it shrinks TTV, slashes TCO, maximizes ROI and eliminates CO2.

Sesame completes the circle

Sesame by ITRenew is rooted in this next-gen philosophy. Sesame’s rack-scale solutions start with premium decommissioned gear from global hyperscalers. They’re then redesigned for specific applications, re-architected and recertified in line with Open Compute Project principles, and finally delivered onsite for seamless plug-and-play installation.

These are some of the cutting-edge workloads for which Sesame’s rack-scale solutions can be optimized:

  • Kubernetes: The Kubernetes ecosystem is a popular choice for organizations that want resilient operation of their distributed systems. Thanks to its flexible software infrastructure and open architecture, Sesame delivers the high scalability and clustering needed for Kubernetes orchestrations. Each system is production-ready and capable of being tuned for a variety of container or virtual machine solutions. Cross-rack switching interconnects up to 20 racks and 750+ nodes in a single cluster or network domain.
  • AI/ML: For demanding, resource-hungry applications like AI/ML, Sesame can provide high-bandwidth (up to 100Gbe), low-latency performance as well as iterative processing along with the ability to respond to algorithms and adjust data at scale. Because Sesame packs 50% more compute and storage density into a standard footprint and can be code-trained for AI/ML, it’s a cost-effective, high-performance option for accelerated computing and applications. It puts the power of large-scale infrastructure into the hands of even the smallest teams.
  • Hyper-converged infrastructure (HCI): Marking a huge leap in future-proof flexibility, HCI virtualizes and consolidates what were once fixed functional elements of discrete, hardware-defined systems. Sesame optimizes standardized nodes to provide an HCI layer that makes scaling compute, storage and networking in lockstep—and deploying apps—easier than ever. Configurable clusters that move and scale as needs change make it easy to update code, applications and data structures for new or legacy applications.
  • Edge applications: Rethinking and re-envisioning traditional hardware paradigms is what gave rise to Sesame, so it’s no surprise that Sesame should be ideal for use cases outside the traditional data center. The versatility of Sesame’s rack-scale systems is perfect for deployment in distributed environments. Sesame solutions also come in compact, mobile mini-racks so developers can build a localized cluster (or test and validate pre-deployment software) on mobile production nodes with standard 110V/220V plugs.

Ultramodern modularity

Sesame’s modular building blocks provide the foundation for a circular data center model that delivers consistently outstanding performance across multiple modern workloads. We call this infrastructure without compromise because it extends and enhances the full lifecycle of hyperscale hardware. That very same process doesn’t just eliminate the environmental and logistical costs of new manufacturing. It also produces better optimized, more efficient equipment that reduces ongoing operational costs.
