<div dir="ltr"><div>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.

As long as you need layer 2 only, they're alright -- granted, they
aren't optimized for storage networks, or anything.<br>

Can be sourced pretty cheap in Ebay [0], I know of people using
them without any issues for 10g layer 2 switching.<br>

<div>Unless you have Enterprise Plus (which is the
wallet-emptying version of vSphere), then there's no support
for aggregation/bonding, particularly for iSCSI.</div>
<div><br>
</div>
<div>The best thing to do is set up a number virtual port groups
with one active physical NIC each (the other pNICs on the
vSwitch must be disabled entirely in the port group), assign
an IP to each of them (you create them as a vKernel port
group, not a Virtual machine port group, and then bind each of
them to the software iSCSI adapter. This gives you good
multipathing - most storage vendors then support round-robin
as the method of load-balancing across the ports.</div>
