CFMS have adopted Mellanox Spectrum Open Ethernet switches running Cumulus Linux to deploy an agile, high performance and highly- automated network infrastructure, to underpin its digital test bed, delivering design, manufacture and services for new innovative products.
Advanced modelling, simulation and high performance computing
Create an open, agile and automated Infrastructure
The Centre for Modelling & Simulation (CFMS) is a not-for-profit specialist in high-value design based out of Bristol in the U.K. As a trusted and neutral provider, CFMS’s vision is to be the recognised, independent, digital test bed for the design of high value engineering products and processes.
As with many companies, CFMS infrastructure team was challenged to update its high performance and agile data center network used by customers and members. They faced several issues with the solutions offered by legacy vendors.
Traditional network vendors lead with vertically integrated product offerings in order to reap higher profits and to maintain customer account control. As a side effect, it is difficult to automate and integrate equipment from legacy vendors to build an efficient solution that optimizes operational expense and total cost of ownership.
Since the traditional vendors’ systems are based on the same chipsets, they share similar performance issues. For example, 25/100GbE Ethernet switch chipsets used by most legacy vendors have performance and traffic fairness issues. As a result, it is hard for customers to adopt newer 25/100GbE speeds despite it having a potential to reduce capital expenditure significantly.
CFMS chose Mellanox SpectrumTM Open Ethernet switches running Cumulus Linux to build their infrastructure. Open and disaggregated systems offer customers a choice to build their infrastructure with best of breed, modern and high-performance components.
Mellanox Spectrum switches support a robust and high-performance 25/100GbE data path with high bandwidth, zero packet loss, and consistent low latency. Cumulus Linux is a powerful open network operating system that allows operators to automate, customize and scale using the same DevOps principles as those used by the mega- scale data centers. With Cumulus Linux, all standard Linux server automation tools are readily available for network infrastructure automation as well. CFMS uses Ansible® toseamlessly automate their server as well as network infrastructure. With Ansible based automation, CFMS can accomplish network changes that traditionally took days, in amatter of few minutes.
Key benefits of the solution
Open, agile and automated infrastructure
Infrastructure and operations teams are under constant pressure to deliver higher performance with tighter budgets. Agile and automated infrastructure not only reduces operational costs but also brings intremendous agility.
CFMS was using Ansible playbooks to automate the server infrastructure. With Cumulus Linux supporting Ansible, CFMS used Ansible to support the network infrastructure as well. Using Ansible dramatically simplified the network operations. With standardized Ansible playbooks, the possibility of human-induced network error was also greatly reduced.
The Mellanox SN2100 switches pack 16x100GbE ports in a half-width compact form factor. Two such switches can be installed side-by-side to provide active-active redundancy in 1U rack space. Mellanox Spectrum switches provide the best forwarding scale for layer-2, layer-3 as well as network virtualization applications.
Reduced total cost of ownership
Mellanox Spectrum Open Ethernet switches support ONIE as a bootloader and provide customers with a widest choice of open network operating systems. This frees customers from vendor lock-in and gives them the ability to pick the best-of-breed and “fit for purpose” software. Open Ethernet brings transparency to solution pricing and reduced capital expenditure. Also, 25/100GbE speeds improve cable utilization and effectively bring down cabling cost. With sub-100W power consumption, SN2100 Ethernet switches have the lowest power footprint in the industry. This power efficiency further reduces the operating costs associated with the solution.
CFMS infrastructure and automation team were tasked to update its high performance and agile data center. Traditional vertically integrated solutions lacked performance and were difficult to automate. CFMS adopted Mellanox Spectrum Open Ethernet switches running Cumulus Linux to build their network. CFMS employs Ansible with the open Linux-based environment to build an agile, high performance and highly- automated infrastructure.
