versions) off er features that mak e them ideal for use in rack - intensive deployments in less-than-ideal environ- ments. With consistent, small-footprints, Netr a servers allow for easy deployment in industry-standard rac ks.
Cable/Broadband Government agencies are der egulating bandwidth, making hundreds of megahertz of bandwidth available f or the emerging technologies and s ystems providing broadband wireless access.
The Netra 240 server inc ludes integrated high-bandwidth networking, supported by the Solaris Operating System. A wide r ange of middlewar e applications is also available to r educe implementation and deployment time.
• Serial Management: An RJ-45 serial por t provides a console port as well as an out - of-band serial management interface. • USB: T wo USB por ts support ZIP drives and other peripherals. • SCSI: An external Ultr a160 SCSI por t enables connection of disk arra ys and other high- speed storage de vices.
Chapter 2 Netr a 240 Server Architectur e Sun designed the Netra 240 server s to deliver multiprocessor performance, scalability , and flexibility in con ven- ient 2 RU enclosur es.
Sun Microsystems, Inc. Front Access Normal operations in a deployed environment typicall y involve , at some point, tasks such as putting a server in standby mode, s wapping a hard disk drive, or r e - configuring the system.
• T wo USB por ts • One full- length PCI slots and two half - length PCI slots • Daughter - board connector for the optional Sun Crypt o Accelerator 500 boar d • System management controll er .
• Dual DTLBs with progr ammable page size support offer performance impro v ements for floating point - intensive applications. • A 128 -bit DDR1 SDRAM memory inter face oper ating at 133 MHz/266 MHz lever ages commodity memory to provide e xceptional price/ per formance and high main memory throughput.
with main memory , improving sequential PCI DMA performance. This approac h minimizes J-Bus tr ansactions for I/ O and enhances performance for I/ O access to main memory . In addition, the JIO Hostbridge ASICs suppor t PCI DMA write and read bursts of 1 KB (32-bit PCI) and 2 KB (64-bit PCI) with no disconnect.
Serial Ports Serial ports provide a convenient wa y to connect Netra 240 servers to terminal and other serial de vices using two asynchr onous serial por ts. The serial A por t (RJ-45 connector) is used as a console and serial interface to the System Management C ontroller ASIC and ALOM.
Based on the Broadcom BCM5822 co-processor , the SCA 500 board accelerates a variety of computa tion- inten- sive cryptographic algorithms f or security protocols in e- commerce applications. The SC A 500 daughter board off - loads SSL functionality normally performed by system CPUs.
S ystem Configur ation Card System administr ators often need to r eplace or upgrade a server with minimal downtime. T o facilitate faster upgrades and r epairs, the System C onfiguration Card (SC C) stores the Netra 240 server’s s ystem configuration, including the host ID, MA C address, and NVRAM settings.
The following table summariz es the Netra 240 server’s enclosur e and power specifications. T able 2-2: Enclosur e and power specifications of the Netra 240 server . Configur ation Netra 240 Server Dimensions Height: 87.4 mm (3.44 in.) – 2 RU Width: 425 mm (16.
Chapter 3 Softw are f or Deploying Highly-A vailable Services The need for continuous opera tion in mission- and business- critical environments demands not onl y well- designed hardwar e but sophisticated softwar e capabilities as well.
many of the k ey elements that enable ef ficient, centralized administr ation and automation. For e xample, admin- istrators can boot Sun systems r emotely over the network and can install operating systems from r emote system administration server s.
ALOM supports the following remote s ystem management capabilities: • Host status monitoring and automatic server r estar t: ALOM monitors en vironmental conditions, as well as the status of the power suppl y and fans in the Netra 240 server . It provides a service indica tor and event or failur e notice to administr ators.
• Reduce tr affic congestion and increase network ef ficiency • Control user and application access to netw ork resources • Gather detailed network use statistics and accounting data f or usage .
Chapter 4 Service Solutions Qualified system administra tive talent is increasingly e xpensive and hard to find in the T elecom industry . As an organization continues to grow , it must extend the e xper tise of its valuable s ystem administrative staff—asking it to manage larger and larger numbers of s ystems.
W orkforce Development Solutions A properly tr ained staff can help ensure high l evels of availability , fast and accur ate deployment of new pr oducts and services, quic k identification of problems, and r apid response to system fail ures and interruptions.
Chapter 5 C oncl usion T oday’s organiz ations are facing many c hallenges. T elecommunications opera tors must be on- line 24 hours a day and systems must be managed to handle peak loads without disruption or service degr adation.
