ESX does not support LACP, only static trunking with a host-configured path selection algorithm.
Look at Infiniband. Even QDR (32 Gbit) is cheaper per port than most 10GbE solutions I've seen, and SDR/DDR certainly is. If you want to connect ESX to storage directly via IB you will find some limitations, but between head and backend storage you shouldn't have as many. -Will ________________________________ From: zfs-discuss-boun...@opensolaris.org [zfs-discuss-boun...@opensolaris.org] on behalf of Kyle McDonald [kmcdon...@egenera.com] Sent: Friday, November 12, 2010 10:26 AM To: Edward Ned Harvey Cc: zfs-discuss@opensolaris.org Subject: Re: [zfs-discuss] Faster than 1G Ether...

I'm not sure it will help though, given the algorithms that LACP can use to distribute the traffic. -Kyle > Is there a better option?
