I have fairly extensive experience with the Quanta LY2 10GE switches, and they
work very well for some environments. Here are some basic impressions:
- Broadcom Trident chipset
- Similar performance to other Trident switches (ideally line rate, but small
buffers)
- Cisco-like configuration int

Anyone have worked with the switching vendor Quanta for their 10ge switching as
TOR? [1] Their spec looked interesting and they are quiet cheap.

That's pretty standard for a cut-thru ToR switch of this style. Cut-thru
switches generally need a lot less packet buffer spa

Arista 7050S-64 48 x 10GE + 4 x 40 GE, price around 25k$ in gpl.
Large buffers, supports MLAG, DCB, wire-speed L2/L3 (OSPF,BGP), but doesn't

Well, talking about HP´s A5920/A5900 series. Last time I was looking,
their virtual routing instances haven´t supported IPv4 multicast, nor
IPv6 multicast/unicast, nor any policy based routing.

this is incorrect: the ex4550 will do l2vpn/l3vpn but not vpls. The X480
does vpls, but not the X670.

Cisco also now has the Nexus 6001 but I don't know of its ability to do
BGP or support things like Netflow. 48x10GE+4x40GE in 1RU. Also likely
doesn't have huge packet buffers. From: Piotr

Network visibility wasn't mentioned as a requirement, but it is worth
considering since the ToR switches are the best place monitor server
network I/O, tunneled traffic (VxLAN, GRE etc), storage (iSCSI, FCoE,
HDFS etc).
The Nexus 5548 switch does not include monitoring (i.e. no

Hi,
I do suggest you go over EN offering with a fine tooth comb.
We experienced a whole lot of issues with 6 x650:
. from hardware licensing (start at shipping from the fab and
not when the customers get them);
. software licensing (have to license every box even the
although everyone here seems to hold Cisco in contempt, the Nexux 5548 is a
rock-solid switch - at least that has been my experience with it.

We use IBM networking (used to be BLADE networks) Rackswitch 8264. They will do
TRILL, and have multi-chassis link aggregation, they call vLAG. We use this for
cross datacenter aggregation. They do have the L3 features you are looking for
and BGP as a possibility, but no full tables. It is a c
