Its a long time since I did not even talk about the converged infrastructure and what is happening around us in this technology space. Yes, I have moved to #SDDC and thus those did not matter much to me off late. However yesterday when I saw this note from my old friend Rotem, I was surprised that how the converged infrastructure is moving into scalability and proving me wrong that they are not resilient to the need of Multi-Hop FCoE.
HP releases Virtual Connect Firmware v4.00 and that’s a major firmware release. The major features of 4.00 address networking aspects in the data center.
For instance, Dual-hop FCoE now allows Virtual Connect to aggregate FCoE traffic in a converged fabric in addition to the one-hop of FlexFabric. So with this release HP proves that Virtual Connect is no longer a “black box” for networking admins.
With Dual-Hop, HP extends convergence to Flex-10 family with ‘D’ postfix only without native FC support on those platforms.
The Dual-hop feature works by FIP snooping to next upstream switch. FIP snooping is the BB-5 defined protocol which leverages DCBX, PFC, ETS to set up a Dynamic ACL path to the next upstream switch. The advantages of FIP snooping in FCoE context is that by virtue of FIP snooping, a device without a native Fibre channel interface can filter FCoE traffic to the upstream switch and thereby provide an FCoE path. This allows a networking configuration of less expensive FIP snooping edge devices to aggregate FCoE traffic combined with more expensive FCF at aggregation/core level.
It was good to know that they are also working on Multi-Hop FCoE which will break the barrier of Two Hops in future.
My dear @Cisco, are you still listening ?
Correction: #SDDC took a toll on me and I did not realize until my UCS Architect friend Anuj Modi told me that Multi-Hop is a reality and it was out since November last year. Here is the article.
