Scaling up vs. Scaling out:  for years, IT architects have been debating the respective merits of big box vs. multi-box solutions to achieve scalability.

 

Big box solutions can be simpler to deploy and manage but they are typically more expensive to acquire and offer limited upgradability and future proofing.

 

With the recent success of cloud computing, the question has been settled for compute and storage: only distributed multi-box architectures can achieve the level of scalability and availability required for cloud based applications.

 

As network architect are redesigning enterprise networks to meet the demand of next generation applications including a massive increase in traffic generated by the broad adoption of video, peer-to-peer communications, BYOD and personal cloud storage, they are evaluating options for migrating the aggregation and core layers to 10/40 Gigabit Ethernet to eliminate bottlenecks.

 

Traditional three-tier network design with “big-box” chassis at the aggregation and core require a significant up-front investment and offer limited scalability and future proofing.

 

On the other hand, adopting a distributed “multi-box” architecture at the aggregation/core can deliver much greater scalability and future proofing with an easier “upgrade as you go” model. It enables network architects to add capacity exactly where it is needed in the network unlike a “big-box” chassis approach with all ports located in the same closet.

 

This week, Brocade is introducing a new family of high-density fixed-port 10/40 GbE switches purposely designed for “scale-out” networking at the aggregation/core. Be sure to check out the Brocade ICX 7750 press release for more details.
