What is leaf -Spine Architecture and How to Build it?

图片
The traditional data center computing network consists of an access layer, an aggregation layer, and a core layer, with north-south traffic as the mainstay.Traditional network structures have supported various types of data centers for a long time. However, with the rapid growth of new applications and data volume, the scale of data centers keeps expanding, and the requirements for network architecture are also increasing. East-west traffic has gradually become the mainstream mode in data centers. Therefore, a new network topology architecture —  Leaf-spine structure  is born in data center.  So what is a leaf-spine network architecture? What are its advantages? How to build hyper-scale leaf-spine architecture? This article will focus on everything you need to know about leaf-spine network architecture. What is Traditional Three-Tier Network Architecture The figure shows the typical topology of the traditional three-layer network architecture: Access Layer : Access switch...

Asterfusion Ultra -low latency switch- Ceph cluster deployment and OpenStack integration

图片
  Ceph is a very popular and widely used SDS ( Software Defined Storage ) solution, which can provide object, block and file-level storage at the same time. This article will show you how to use Asterfusion CX-N series ultra-low-latency switches to form a network to carry Ceph storage clusters and use Ceph as the storage backend to integrate with Openstack. Before the popularization of cloud technology, common storage solutions in the IT industry were DAS, SAN, and NAS.  Currently, the three traditional storage solutions have some problems in terms of price, performance, scalability, deployment, operation and maintenance in their respective application scenarios.  So, there is no one-size-fits-all solution on storage. In actual production environments, we often need to make trade-offs based on data size, performance requirements, budget, and application scenarios. The emergence of Ceph is a compromise solution to the above problems. What is Ceph ? Ceph is a very popular o...
