Figure 8: HP ProCurve 6600-24G-4XG Switch—ProVision ASIC architecture overview
Description
The HP ProCurve 6600-24G-4XG Switch is a data center-optimized, advanced Layer 3 1U stackable switch
with 20 10/100/1000Base-T ports, 4 dual-personality ports, and 4 SFP+ 10-GbE integrated ports. The 6600
series 1U form factor switches are enhanced for server edge connectivity with front-to-back cooling, redundant
hot-swappable power, and redundant hot-swappable fans. The foundation for all these switches is a purpose-
built, programmable ProVision ASIC that allows the most demanding networking features, such as QoS and
security, to be implemented in a scalable yet granular fashion. With a variety of connectivity interfaces and
expanded buffering, the 6600 switches offer excellent investment protection, flexibility, and scalability, as well
as ease of deployment and reduced operational expense.
The ASIC layout shown in Figure 8 for the data center-focused 6600-24G-4XG switch adds an NGX ASIC to
provide a 10-Gb uplink capability to this switch model. Unlike the 3500yl-24G switch, where the yl 10-Gb
module is rear mounted, the 6600-24G-4XG switch moves the 10-Gb ports to the front of the switch for
simplified cabling.
Examining the Gigabit ports, the last four ports are dual personality, meaning they can be used as RJ-45
copper ports or mGBIC (or SFP) fiber ports. The 6600-24G-4XG switch offers four ports of 10-Gb using SFP+
port slots—instead of X2 slots used on earlier 10-Gb ProCurve products. There is no CX4 option for these
SFP+ products, but ProCurve offers a low-cost copper direct attach cable (or DAC) option that is based on the
Small Form Factor Committee (SFF-8431) standard. The DACs are essentially a preterminated cable with SFP+
compatible transceivers. DAC products are available in 1-, 3-, and 7-m lengths, primarily for close proximity
connections to 10-Gb servers or other SFP+ switches, such as in the same server cabinet. The 6600 accessories
portion of this guide provides further details about the direct attach options.
The fabric-switching capacity is listed the same as the 3500yl-24G switch, where we account for the added
NGX ASIC and its maximum capacity of 28.8 Gbps of throughput. Table 2 compares the 6600-24G
architectures to that of the 3500yl-24G switch.
