The HP 6600-48G-4XG Switch (manufacturer part number J9452A) is a 1U rack-mount switch from the HP 6600 series, specifically designed for deployment in the server edge environment of data centres. It serves as a network connection between servers and the core network, offering a combination of high performance, scalability, and flexible configuration. The switch series is designed for integration into existing infrastructures and supports a wide range of network functions required for demanding environments.

Applications

The switch is intended for use in data centres and server edge environments where reliable, highly available, and scalable network connectivity is required. It is particularly suitable for environments requiring high port density, redundant power supply, and hot-swap capability for fans and power supplies. The reversible cooling from front to rear allows for flexible installation in racks with different airflow directions.

Features and Equipment in Detail

The HP 6600-48G-4XG Switch features 48 ports with 10/100/1000BASE-T connections, as well as four 10-Gigabit-Ethernet SFP+ ports for high-speed connections. The SFP+ ports support the use of transceivers for various transmission media, including single-mode and multi-mode fibre, as well as direct-attach cables (DAC). The switch series is based on a specially developed, programmable ProVision ASIC, which enables the implementation of complex network functions such as Quality of Service (QoS) and security functions in an extensible and granular manner. This architecture ensures high flexibility in network configuration and control.

Technology Explained Simply

The ProVision ASIC is the central processor of the switch, responsible for processing and controlling network traffic. It enables precise control of data flow, especially in prioritising data streams (QoS), which is important for critical applications such as VoIP or video transmission. The enhanced buffering ensures better packet processing under high loads and reduces the likelihood of packet loss. The hot-swap capability for fans and power supplies means these components can be replaced during operation without shutting down the switch, thereby increasing availability.

Compatibility and Accessories

The switch is compatible with various accessories that support installation and operation. These include rack-mounting kits, Air Plenum Kits, and various patch cables in CAT5e and CAT6 categories. The SFP+ ports can be connected with transceivers for 10-Gigabit-Ethernet, for example, with SFP+ transceivers for long-haul transmission (LR, up to 10 km) or with direct-attach cables (DAC) for short connections within the rack.

Mounting and Installation

The switch is designed for mounting in standard 19-inch racks and occupies 1U height. The reversible cooling allows for flexible placement in the rack, regardless of airflow direction. The hot-swap capability for fans and power supplies simplifies maintenance, as replacement operations can be performed without interrupting operation.

Operational Advantages

The HP 6600-48G-4XG Switch offers high availability through redundant components and hot-swap capability. The programmable ASIC technology enables flexible and extensible network configuration that can adapt to changing requirements. The enhanced buffering and QoS support ensure stable network performance, even under high loads. The combination of high port density and high-speed connections makes the switch a scalable solution for growing networks. Easy implementation and reduced operating costs are further advantages achieved through the architecture of the switch series.
