Description
The HP ProCurve 6600-48G-4XG Switch is a data center optimized, advanced Layer 3 1U stackable switch
with 48 10/100/1000Base-T 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.
To achieve wire-speed forwarding on all ports, the 6600-48G-4XG model is configured with two NGX
10-Gb ASICs. Each NGX connects to two downstream 10-Gb SFP+ ports, and therefore provides full line-rate
capacity across all four 10-Gb ports. Because each NGX is only connected to two 10-Gb ports, the maximum
throughput of each NGX ASIC is only counted as 20-Gb full-duplex (or 40-Gb switching). Thus, unlike the
3500yl-48G architecture, where the 4 x 10-Gb module connects to a single NGX ASIC, thereby achieving a
maximum throughput of 28.8 Gb across all four 10-Gb ports, the 6600-48G-4XG switch can achieve 40 Gb of
throughput.
