CloudLinux Achieves Low-Latency Connectivity with a Spine-Leaf Architecture
Located in the United States, CloudLinux has spent more than 500 combined years working on Linux, an operating system designed to give shared hosting providers a more stable and secure OS. Recently, its growing business leads to various problems. Thus, CloudLinux decides to expand its IT infrastructure. FS helps CloudLinux build a spine-leaf architecture to address its current problems.
With its rapid business growth, the requirements for CloudLinux data centers grow more complex. Its current architecture can no longer support the increasing traffic load. CloudLinux is now faced with the following challenges:
Insufficient speed of equipment
Single point of switch failure when equipment interfaces fail
Insufficient equipment performance caused by the large increase of east-west traffic in the new generation data center
More transmission hops and higher delays when exchanging traffic in its traditional three-tier architecture.
FS chooses to deploy a spine-leaf solution to optimize CloudLinux's current data center network. N8560-32C switches are used in the spine layer and N5860-48SC in the leaf layer. Both switches use MLAG stacking technology to ensure network stability, avoid single point of failure and increase switch performance.
This spine-leaf architecture enables load sharing, and the uplink of each leaf switch works in a load-balanced manner, making full use of the bandwidth. Moreover, the solution supports RoCE which can achieve lower latency than its predecessor, iWARP protocol. The RoCE HCAs (Host Channel Adapter) of FS can now achieve a minimum latency of 1.3 microseconds.
The Spine-leaf solution provided by FS helps CloudLinux solve many data center problems it faces at present. CloudLinux can now enjoy a stable and reliable data center network which adapts to the growth of its business, enables flexible deployment, and reduces the cost of overall deployment and maintenance. The Spine-leaf solution also provides an effective development strategy for CloudLinux to tackle future problems.
