Good point about Arista - Doug Gourlay, of [ex-]Cisco fame, is probably the person to ask all possible questions about those solutions. Cisco UCS is missing, also - looking at the Nexus deployment as ToR solution (2K + 5K, even 1KV, considering the needs for virtualization, also) with all benefits of both traditional ToR and E/MoR will definitely shed some light in the debate on whether L3 in ToR makes any sense at all (e..g how would you VMotion across racks?!? - how you you sync SANs across L3 in the DC (tunnel?!?), etc.). Here are some interesting articles associated with technologies in new DC designs, for example, allowing some rethinking of the L3 question: http://www.internetworkexpert.org/ - search for ToR and VMotion articles (actually poke arond the whole blog - it is very good) http://blogstu.wordpress.com/2009/10/05/fcoe-ecosystem/ (start from 1, of course) ...etc. ***Stefan On Fri, Nov 13, 2009 at 7:33 AM, Randy Bush <randy () psg com> wrote:
