Sun Microsystems, Inc. Introduction P1 Chapter 1 Introduction Over the past few years, deregulation and privatization have created intense competition in the worldwide telecommunications market. The marketplace has continued to evolve as voice and data solutions become more integrated and next-generation wireless, video, and messaging technologies emerge.
P2 Introduction Sun Microsystems, Inc. Figure 1-1: The Netra 240 server is ideal for a wide range of applications and users. versions) offer features that make them ideal for use in rack-intensive deployments in less-than-ideal environments. With consistent, small-footprints, Netra servers allow for easy deployment in industry-standard racks.
Sun Microsystems, Inc. Introduction P3 Cable/Broadband Government agencies are deregulating bandwidth, making hundreds of megahertz of bandwidth available for the emerging technologies and systems providing broadband wireless access. A wide variety of technologies and system implementations are being put into place to provide many different service offerings—cable, satellite, and DSL, for instance.
P4 Introduction Sun Microsystems, Inc. The Netra 240 server includes integrated high-bandwidth networking, supported by the Solaris Operating System. A wide range of middleware applications is also available to reduce implementation and deployment time. Standard advanced manageability features allow for efficient, remote system administration, and high reliability to enable ease of integration with centralized management services.
Sun Microsystems, Inc. Introduction P5 • Serial Management: An RJ-45 serial port provides a console port as well as an out-of-band serial management interface. • USB: Two USB ports support ZIP drives and other peripherals. • SCSI: An external Ultra160 SCSI port enables connection of disk arrays and other high-speed storage devices. • PCI: One full-length PCI slot and two half-length PCI slots are available for individual PCI cards.
P6 Netra 240 Server Architecture Sun Microsystems, Inc. Chapter 2 Netra 240 Server Architecture Sun designed the Netra 240 servers to deliver multiprocessor performance, scalability, and flexibility in convenient 2 RU enclosures. To this end, high-volume components and application specific integrated circuits (ASICs) have enabled a greatly reduced part count while providing high reliability and low cost without compromising access to expansion options through high-performance, standardized interfaces.
Sun Microsystems, Inc. Netra 240 Server Architecture P7 Front Access Normal operations in a deployed environment typically involve, at some point, tasks such as putting a server in standby mode, swapping a hard disk drive, or re-configuring the system. With the Netra 240 server, administrators can accomplish such tasks through a push button switch, a rotary switch, and a System Configuration card— all accessible behind the front bezel.

The following sections discuss these key components.
Sun Microsystems, Inc. Netra 240 Server Architecture P9 • Dual DTLBs with programmable page size support offer performance improvements for floating point-intensive applications. • A 128-bit DDR1 SDRAM memory interface operating at 133 MHz/266 MHz leverages commodity memory to provide exceptional price/performance and high main memory throughput. • ECC (memory) or parity (J-Bus) protection on all interconnects helps ensure highly-reliable and available systems.

This approach minimizes J-Bus transactions for I/O and enhances performance for I/O access to main memory. In addition, the JIO Hostbridge ASICs support PCI DMA write and read bursts of 1 KB (32-bit PCI) and 2 KB (64-bit PCI) with no disconnect. 64-bit PCI DMA writes execute at peak PCI bus throughput.

P12 Netra 240 Server Architecture Sun Microsystems, Inc. Based on the Broadcom BCM5822 co-processor, the SCA 500 board accelerates a variety of computation-intensive cryptographic algorithms for security protocols in e-commerce applications. The SCA 500 daughter board offloads SSL functionality normally performed by system CPUs. Using 3DES, it accelerates various operations such as authentication and bulk encryption.
Sun Microsystems, Inc. Netra 240 Server Architecture P13 System Configuration Card System administrators often need to replace or upgrade a server with minimal downtime. To facilitate faster upgrades and repairs, the System Configuration Card (SCC) stores the Netra 240 server’s system configuration, including the host ID, MAC address, and NVRAM settings. With the SCC, administrators can easily replace a Netra 240 server with minimal reconfiguration by transferring the identity from one system to another.

Sun Microsystems, Inc. Software for Deploying Highly-Available Services P15 Chapter 3 Software for Deploying Highly-Available Services The need for continuous operation in mission- and business-critical environments demands not only welldesigned hardware but sophisticated software capabilities as well. The Netra 240 server comes pre-installed with the Solaris Operating System (Solaris 8 HW 7/03) and integrated support for remote management software.
P16 Software for Deploying Highly-Available Services Sun Microsystems, Inc. many of the key elements that enable efficient, centralized administration and automation. For example, administrators can boot Sun systems remotely over the network and can install operating systems from remote system administration servers. Solaris JumpStart software, a standard component of the Solaris Operating System, enables fully automatic and remote operating system installation based on custom profiles and scripts.
Sun Microsystems, Inc. Software for Deploying Highly-Available Services P17 ALOM supports the following remote system management capabilities: • Host status monitoring and automatic server restart: ALOM monitors environmental conditions, as well as the status of the power supply and fans in the Netra 240 server. It provides a service indicator and event or failure notice to administrators. The service processor also provides an automatic server restart (ASR) function triggered by a system alarm.

Sun Microsystems, Inc. Service Solutions P19 Chapter 4 Service Solutions Qualified system administrative talent is increasingly expensive and hard to find in the Telecom industry. As an organization continues to grow, it must extend the expertise of its valuable system administrative staff—asking it to manage larger and larger numbers of systems. In addition, maintaining high availability means relying on people and processes even more than products.
P20 Service Solutions Sun Microsystems, Inc. Workforce Development Solutions A properly trained staff can help ensure high levels of availability, fast and accurate deployment of new products and services, quick identification of problems, and rapid response to system failures and interruptions.
Sun Microsystems, Inc. Conclusion P21 Chapter 5 Conclusion Today’s organizations are facing many challenges. Telecommunications operators must be on-line 24 hours a day and systems must be managed to handle peak loads without disruption or service degradation. Computing infrastructures must scale both horizontally and vertically—without downtime or unnecessary system complexity.
