More enterprises are deploying SDS, but they sometimes run into problems related to support and scalability.
For those following the VRF Series, we currently have a topology built that consists of a segmented Layer 3 first hop network and remotely networked by carrying the isolation from the BrWan router to Main. This article covers, shared services, the next step in our journey to understanding VRFs for Segmented Layer 3 Networks.
The configuration focus is solely on the router Main. The shared services VRF that will be created could serve as a place to connect something that all other VRFs must have access to. Organizations should evaluate their requirements closely before deploying this configuration.
An organization that requires stateful inspection between two areas may choose to connect two or more VRFs together using an L4 or Next Generation Firewall (we will cover this in Article 5). The security ramification of having a shared services VRF, as described in this article, is that devices connected in this area could be used as a proxy into other areas. Therefore, careful planning and proper device level security is important prior to deploying this type of architecture.
The technologies covered here include:
The logic of Continue reading
High performance computing in its various guises is not just determined by the kind and amount of computing that is made available at scale to applications. More and more, the choice of network adapters and switches as well as the software stack that links the network to applications plays an increasingly important role. And moreover, networks are comprising a larger and larger portion of the cluster budget, too.
So picking the network that lashes servers to each other and to their shared storage is important. And equally important is having a roadmap for the technology that is going to provide …
