[AusNOG] Cheapest half decent 10Gbps switch (for iSCSI only)

Mon Apr 20 19:10:51 EST 2015

Just be sure as you don't invest too much in a switch that's going to be
replaced in short order. While you're at < 1k IOPs, most anything will
work, to a point. Jumbo frames is the main thing. When the time comes you
want to run SSD or multiple arrays, you'll need a DCB switch, with the
price tag that entails. So create the expectation with the client now that
this is an interim solution, until you have the necessary budget.
