Software Defined Photonic Infrastructure for the Accelerator Era
Signed in as:
Users can start the journey to a modern data center using Drut’s Software Platform (DSP) for new and existing data center equipment. We used our knowledge gained from building the Drut platform and applied some of the same concepts to our software practices. The key concept carried through all our product offerings, is to always maintain fluid resources at multiple layers, not just at the hardware layer, all the way up the software stack creating a closed looped system.
Users need to have a system that they can redeploy with confidence. What customers tell us is that once they get their systems deployed with traditional static box designs, they tend to avoid touching it again, meaning that when the next app needs new infrastructure or the resources need to change, it requires new racks of gear. We want to make repurposing and rebuilding infrastructure easy. We want to make the system architecture dynamic and responsive to applications.
At Drut we believe that the next wave of modern data centers requires real hardware innovation which is our PCIe over Photonics (PoP) disaggregated architecture, but this is only made possible with an innovative approach to cloud software services. Rather than trying to abstract the hardware layer away with some virtualization software layer, we want to disaggregate both hardware and software in order to close the loop between hardware composition and the software application layer provisioning. Our platform strategy provides:
What We Are
Drut is a system company, building a platform for efficient, high-performance AI, HPC, Cloud scale out built around software and photonics integration
What Challenges is Drut Focused on Solving?
1.Memory scale out mismatch
2.Interconnect bandwidth mismatch
3.Infrastructure scale requires sprawl and high cost
4.Resource utilization inefficiency that underpins energy waste
Our Architecture Approach
By crossing the final barrier from electrons to photons – architecture matters!
Latency: Direct connect, all photonic fabric provides the lowest possible latency allowing valuable machine resources to be directly connected into a composable node
Distance: Photonics eliminates the distance and physical locality challenges in the data center
Complexity: Removing stacked hierarchies of switches, protocols and overlays is the most direct method to remove complexity
Efficiency: Grouping resources via direct connect around workload requirements resolves the stranded resource challenge
Security: Like a SAN, workloads do not transgress over racks, spines and cores, they are isolated
OPEX: Using data center resources more efficiently, means getting more from less, such as less power, less cooling, less space
CAPEX: Reducing data center waste and decoupling resource upgrade cycles from the server upgrade cycle means capital can be spent with greater fidelity on what matters most
Software Defined Infrastructure Enabled by PCIe/CXL over Photonics
This approach addresses four challenges: (i) stranded resources, (ii) latency, (iii) power/cooling and (iv) static topologies. The DynamicXcelerator addresses these challenges with an all photonic, direct connect fabric that is reconfigurable on demand.
The DX Fabric uses a building block approach for system design. In the most basic form, it can be deployed in a software only version as an on-prem cloud software suite. We can help you turn up services for bare metal machines, compute, storage and application deployment. The software only deployment model requires the Compute and Software Blocks.
In the full DX Fabric experience, the Resource, Photonic and System Blocks are also deployed. This brings together a complete infrastructure experience wherein hardware resources can be composed and driven by software. It is a full closed loop system that is responsive to the needs of the users.
The DynamicXcelerator has many tangential benefits on OPEX, CAPEX, power efficiencies, security, but the adoption will occur because a photonic fabric at scale is the next evolution of the modern data center and for the first time in thirty years the technologies required to make the transition from electrons to photons are available.
