◎ Brocade’s Data Centre Ethernet Strategy

I attended the Brocade Analyst and Tech Day last week as a guest of Brocade where I got to learn more about product, technology and strategy. In particular, the event was led by the launch of the Brocade VDX 8770.

TL:DR version: I have a better understanding of Brocade’s market strategy, insight into the technology and believe that Brocade has a a good product here. The proof will be in the delivery, and whether Brocade can let go of it’s storage legacy (FibreChannel) and properly commit to Ethernet. They will need to convince networking professionals that their product managers understand the market and requirements to get them to switch to Brocade. At this time, I think Brocade has a chance of making that happen based on the emphasis of VCS Fabric and Automation.

Where I’m less comfortable is that Brocade will rely on external parties to deliver the software automation – that’s a strategy that has NOT worked in the last 20 years. There is no reason to believe this anything has changed.

How TRILL (and SPB) can reduce STP risk and mitigate impact

In this post, I’m looking at network designs with ECMP cores using TRILL or SPB, I’m realising that STP is equally improved in terms of risk and performance by reducing the STP domain size which leads to better stability, reduced risk and impact mitigation
