Earlier this September, I attended the Tech Field Day Networking Field Day 8 event. Over the course of three days, we saw presentations from many very interesting vendors including a mix of startups and established market leaders. One trend that really stuck out to me more this time around than at any previous NFD event was a nearly ubiquitous emphasis on data center network fabric management. In other words, truly managing an entire data center network (or at least a sub-block of it) as a single unit.
Last week I attended Networking Field Day 7, and was introduced to Pluribus Networks. Pluribus is taking an interesting approach to building the data center fabric, by combining high-performance data center top-of-rack (ToR) switching with powerful server internals in a platform they’ve dubbed the Freedom Server-Switch.
I came across a good tip the other day that was very helpful during a small site firewall migration. Here’s the back story:
I was migrating a small single-site customer that had, up to this point, been using a FIOS-provided consumer-type router/firewall/access point to some Cisco gear including an ASA firewall for better firewall/VPN capabilities. This is fairly common with small businesses that start out with essentially consumer-style connectivity and finally begin to grow to a point of needing business-grade capabilities. My preparation went fine, and when the time came I swapped the ASA firewall in place of the FIOS-provided one. Then everything broke.
The better part of a year ago when the Cisco CSR1000V was publicly released, I quickly tested the notion of running the Cloud Services Router in VMWare Fusion on the Mac, rather than on a full vSphere server. Since then, I occasionally see that some readers land on my blog after searching for the terms “CSR1000V GNS3” looking for assistance in integrating the CSR with the popular networking simulation platform. The CSR1000V is attractive as it provides a means to run IOS-XE, the same variant as on the ASR-series routers, and unlike Dynamips, Cisco has blessed use of the CSR with the 2.5 Mb/s throughput-limited trial license as a legitimate labbing platform. Last night I decided to see if it could be done. Turns out, it’s easy.
