For some customers, the Layer 3 features and redundant power supply features of the HP ProCurve Switch
5400zl series also make it well-suited as a distribution switch . New to the 5400zl and 3500 series is the
optional deployment of a Premium License feature group as opposed to the standard offerings of the Intelligent
Edge feature group . The Premium License contains all of the Intelligent Edge features plus additional features
oriented towards routing that are useful when deploying the switch at the distribution level of the network . The
Premium License feature group includes protocols such as PIM-SM, PIM-DM, OSPF-ECMP, and VRRP .
HP ProCurve Switch 6200yl-24G-mGBIC
The HP ProCurve Switch 6200yl-24G-mGBIC is an advanced Layer 3 stackable at 1U height . It has 24 mini-
GBIC slots and an expansion slot for an optional 4-port 10-GbE module . Designed to be deployed as an
aggregator of traffic from the edge to the core of the network, this switch supports a variety of Gigabit mini-
GBICs, such as SX, LX, LH, and 1000Base-T . The Premium License feature group is standard on the
HP ProCurve Switch 6200yl-24G-mGBIC .
Like the 5400zl and 3500 series switches, the foundation for this switch is a purpose-built ProVision ASIC that
allows the most demanding networking features, such as QoS and security, to be implemented in a scalable
yet granular fashion . With its high-performance architecture, 10-GbE capability, and programmable ASIC, this
switch offers excellent investment protection, flexibility, and scalability .
ProVision ASIC architecture
The ProVision application-specific integrated circuit (ASIC) architecture is the latest-generation HP ProCurve
ASIC technology and is used in the HP ProCurve Switch 8200zl, 5400zl, 3500, and 6200yl series . The
ProVision ASIC architecture consists of multiple network chips interconnected by an active crossbar consisting
of the fabric chip . A network chip is implemented on each of the various line interface modules (also known
as line cards) . The fabric chip is integrated on the switch backplane, which helps reduce the overall size of the
Each network chip represents a node in the system with "links" connecting to the interconnect fabric . Each link
provides approximately 28 .8 Gbps of data bandwidth . In addition, a management module with a dedicated
CPU provides communications control between the network chips and fabric chips .
