6600 series comparison

Table 6 provides a comparison of several categories of capacity and performance levels for the ProCurve

6600 Switch Series. These include the routing and switching capacity (Gbps), switch fabric speed (Gbps),

maximum number of 1 Gbps that can operate concurrently at wire speed, the maximum number of 10-Gbps

ports that can operate concurrently at wire speed, and the size of the routing table (entries).

Routing and forwarding tables

The ProCurve 6600 Switch Series has several routing and forwarding table features that enhance routing and

switching performance. Every NG/NGX interface has its own “best-match prefix” routing table that contains

IP routes and is used for determining how to route the vast majority of incoming packets. Using the best-match

prefix routing table is extremely fast and enables wire-speed routing to be achieved. If the best-match prefix

routing table does not contain an entry that can be used to determine the route of a received packet, then

the main routing table is used. The main routing table can contain up to 10,000 routing table entries.

For Layer 2 forwarding, each switch has a forwarding or MAC table that can contain up to 65,536

entries (64K).

Optimizing the 10-GbE port configuration for wire speed

For the 6600-24XG and the 6600-24G-4XG switch, where the 10-GbE interfaces are oversubscribed

40G:28.8G, these switches are designed to deliver full 10-Gbps wire speed to either one or two ports that are

in a linked state with another device. When three or four ports per block of four 10-GbE ports are in a linked

state, the group of 4 x 10-GbE ports support an aggregate bandwidth of 28.8 Gbps across the linked ports.

Note: The 6600-48G-4XG switch supports full line rate 10-Gb performance, so this section does not apply to

that particular switch.
