Active-Active Datacentre Design

The active-active DC design comprises of many modular components when in unison provide an active/active network architecture to support the existing active/active compute and storage architectures encompassing all datacentres. This allows non-disruptive access to services in the datacentre by automated redundancy in the edge and DCI network infrastructure during a disaster event, without human intervention.    The solution also provides automated failback from a failure event, again with no human intervention. The architecture is also to support Disaster Avoidance, to pre-emptively facilitate traffic changes to facilitate maintenance outages. The design provides the automated failure mechanisms for the public and private WAN and the DCI component of the datacentre bus, which are transparent to all the compute and storage infrastructure.

High availability and active-active ISP module

The new WAN module solution is based on an N+1 highly available architecture, where N is the networking device or POP and +1 is its duplicate. The WAN module is designed to provide CWR redundancy against any component failure and misconfiguration, providing business continuity to and from CWR’s data centres. The design philosophy of the WAN module solution is based on a disaster avoidance model. The concept is to design and implement a robust network solution, providing redundancy at all levels including POPs, inter POP links, WAN links (data centres to upstream POPs), N+1 hardware all complemented with 24×7 monitoring. The solution also provides a roadmap to migrate to future cloud based services.
