<div dir="ltr">My question would be regarding buffer sizes. Looking at the Dell S3048-ON BaseT switch, it has only 4MB buffers, the SFP+ S4048-ON has 12MB buffers, but this is about 1/10th to 1/3 (respectively) of what a Nexus 9300 series has (~37-52MB). <div><br></div><div>Is this really enough to run a converged network environment in a datacentre, especially with iSCSI being one of those protocols?</div><div><br></div><div>(Appreciate any advice either on or off list)</div><div><br></div><div>Thanks,<br>Greg.</div><div><br><div><div class="gmail_quote"><div dir="ltr">On Mon, 4 Jul 2016 at 14:46 Matt Smee <<a href="mailto:m.smee@unsw.edu.au" target="_blank">m.smee@unsw.edu.au</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">

<p class="MsoNormal" style="background:white">I’ve been impressed with the zero touch deployment part of it but still learning/playing with it at the moment. Though it doesn’t seem quite yet ideal in the enterprise access space, there’s some missing features
that I do like such as the various L2 security options but then again it’s definitely more Data Centre focused than enterprise access, though that may change in the future…<u></u><u></u></p>
<p class="MsoNormal" style="background:white">
<u></u><u></u></p>
<p class="MsoNormal" style="background:white">I’d also give a +1 to Ben, why pay so much for simple routing/L3 switching? In 3-5 years with some maturity I can’t see how you could ever justify the $bigvendor prices for some deployments or at least some devices
within the network. Looking at doing 40/100G and we can see its definitely looking like a good option even now.<u></u><u></u></p>

end device connectivity and it's more about moving the packets around.<u></u><u></u></span></p>
