We are planning on moving a large portion of our data center to a colo facility at an financial exchange. We will be using redundant 10-GE connections from our existing pair of 7604 to a new pair of 7606 with Sup720-3B. We won't be doing MPLS/VPN, etc... Just normal L3 routing including PIM sparse mode multicast. Since a significant amount of the traffic will be market data, the line rate will be very bursty including micro-bursts. We will be setting up a series of LLQ queues with Modular QoS CLI and are interested in H-QOS, so I have some questions regarding which 10GB interface.
The choices are: 1) WS-X6704-10GE. The standard linecard. TX queue of 1p7q8t. 16MB per port buffer 2) 7600-ES20-10G3C. TX queue ??? (configurable ???), buffer size ??? 3) 7600-SIP-600 with SPA-10X1GE. TX queue ???, buffer size ??? The SIP and ES20 may be overkill, maybe not. We aren't doing MPLS or VRF, or QinQ or any other tunneling, but we need the most flexible, best 10GB WAN interface that can help us deal with bursting/QOS.
