On todays episode of Priority Queue, sponsor Sonus Networks joins us to explore microservice orchestration for networking, particularly in the context of OpenStack. The post PQ Show 83: Sonus Networks & Microservice Orchestration (Sponsored) appeared first on Packet Pushers.
Find out how SSDs stack up to hard disk drives and how they can benefit your data center.
Remember our journey toward two-switch data center? So far we:
Time for the next step: read a recent design guide from your favorite hypervisor vendor and reduce the number of server uplinks to two.
Not good enough? Building a bigger data center? There’s exactly one seat left in the Building Next Generation Data Center online course.
We’ve all been there. That “non-disruptive” maintenance window that should “only be a blip”. You sit down at the terminal at 10pm expecting that adding a new server to the MLAG domain or upgrading a single switch will be a simple process, only to lose the rack of dual-attached servers and spend the rest of your Thursday night frantically trying to bring the cluster back online.
If I never spend another evening troubleshooting an outage caused by MLAG, I’ll die happy!
While MLAG provides higher availability than single attaching or a creating multi-port bond to a single switch, it comes with the cost of a delicate balancing act. What if there was a way to provide redundancy without MLAG’s fragility and its risk to maintenance windows?
We at Cumulus Networks have seen many of our customers solve these problems by leveraging Cumulus Quagga, our enhanced version of the routing suite, on their server hosts, so we’ve decided to call it Routing on the Host and make it broadly available for download.
By leveraging the routing protocols OSPF or BGP all the way to the server, we can resolve that MLAG problem once and for all.
Over the last five years, Continue reading
