sFlow: ECMP visibility with Cumulus Linux
http://blog.sflow.com/2015/03/ecmp-visibility-with-cumulus-linux.html
SDN analytics and control using sFlow standard. Friday, March 13, 2015. ECMP visibility with Cumulus Linux. Demo: Implementing the Big Data Design Guide in the Cumulus Workbench. Is a great demonstration of the power of zero touch provisioning and automation. When the switches and servers boot they automatically pick up their operating systems and configurations for the complex Equal Cost Multi-Path (ECMP) routed network shown in the diagram. Topology discovery with Cumulus Linux. The first iperf test ac...

Diggin' technology every day. NetApp Flash ray ships… with one controller. Well I suppose it is finally out, or at least in a "limited" way. NetApp apparently is releasing. Their ground-up rewrite all Flash product Flash Ray, based on a new "MARS" operating system (not related to Ontap). When I first heard about MARS I heard some promising things, I suppose all of those things were just part of the vision, obviously not where the product is today on launch day. NetApp has been carefully walking. In the m...

sFlow: Sampling rates
http://blog.sflow.com/2009/06/sampling-rates.html
SDN analytics and control using sFlow standard. Friday, June 26, 2009. A previous posting discussed the scalability and accuracy of packet sampling. And the advantages of packet sampling for. Configure sFlow monitoring on all interfaces on the switch for full visibility. Packet sampling is implemented in hardware so all the interfaces can be monitored with very little overhead. Finally, select a suitable counter polling interval so that link utilizations. For an explanation). For example, to trend ut...

SDN analytics and control using sFlow standard. Tuesday, February 5, 2013. Measurement delay, counters vs. packet samples. This chart compares the frame rate reported for a switch port based on sFlow interface counter. Measurements (shown in blue. Respectively). The chart was created using sFlow-RT. Which asynchronously updates metrics as soon as new data arrives, demonstrating the fastest possible response to both counter and packet sample measurements. Line, trending the ifinucastpkts.
