Design Guide

The data center core is a mechanism to replicate and horizontally scale the data center environment. In the recommended design the aggregation and access layers are regarded as a module that can be duplicated to extend the enterprise. Each data center module provides its own network services locally in the aggregation switches. This approach allows the network administrator to determine the limits of each data center module and replicate as necessary.

Figure 9 depicts the design of the data center core. The aggregation switches for each data center module are attached at Layer 3 to the core. In addition, the aggregation switches house the service modules required to support the server farms.

Management

The Cisco Catalyst Blade Switch 3020 is accessible for management and configuration by any of the following traffic paths:

●Out-of-band (OOB) management

●In-band management

●Serial console port

These traffic paths provide three different management options for network administration and support different user and application interfaces to the Cisco Catalyst Blade Switch 3020. The remote management of the blade servers within the HP c-Class BladeSystem is critical to an efficient and scalable data center. This section discusses these topics, as well as the iLO connectivity options provided using the enclosure to the blade servers.

Out-of-Band Management

OOB management is the practice of dedicating an interface on the managed device for carrying management traffic. It is also the recommended management method for blade systems. OOB management isolates the management and data traffic and provides a more secure environment.

3020 specifications

The NAD 3020 is a classic integrated amplifier that has gained a legendary status among audiophiles since its launch in 1978. Known for its incredible sound quality and value for money, the NAD 3020 has become a reference point in the realm of affordable audio equipment.

One of the main features of the NAD 3020 is its high current design, allowing it to drive a wide range of speaker impedances. This capability ensures that the amplifier can deliver a dynamic sound, characterized by a robust bass response and clear treble. With a power output of 20 watts per channel into 8 ohms, the NAD 3020 is often underestimated due to its modest specifications. However, it can produce remarkable sound pressure levels and handle transient peaks with ease.

The amplifier utilizes a simplified circuit design, which is one of its defining characteristics. This minimalist approach reduces potential signal distortion, enabling the amplifier to maintain sonic integrity. The use of discrete components rather than integrated circuits contributes to its rich, detailed audio reproduction, making it a favorite among purists.

Another key technology featured in the NAD 3020 is its unique power supply design. NAD engineers incorporated a toroidal transformer, which is known for its compact size and low electromagnetic interference. This results in cleaner power delivery, which is essential for maintaining audio clarity and depth.

The NAD 3020 is also equipped with multiple inputs, including phono, line-level, and tape inputs, making it versatile for various audio sources. The built-in phono stage supports moving magnet cartridges, allowing vinyl enthusiasts to connect their turntables directly to the amplifier without needing a separate phono preamplifier.

In terms of build quality, the NAD 3020 features a sturdy chassis that minimizes vibrations, ensuring that audio performance remains stable. The user-friendly design includes a straightforward control layout, allowing users to adjust volume and tone settings with ease.

Throughout its decades-long legacy, the NAD 3020 has influenced countless audio products and remains a benchmark for entry-level amplification. Its combination of power, clarity, and affordability makes it a beloved choice for both new listeners and seasoned audiophiles seeking a dependable amplifier that doesn't compromise on sound quality. The NAD 3020 exemplifies how great engineering can lead to remarkable audio experiences, solidifying its place in the history of hi-fi audio.
