Outstanding 32/64-bit price/performance in a rack-dense 1U, 2-way server for HPC applications

ensuring that customers have all the cables, power distribution units, KVM (keyboard, video and mouse) switch boxes and other components they need, as well as the proper airflow clearances, electrical circuits and other environmental conditions.

IBM ServerGuide (installed from CD) simplifies the process of installing and configuring e325 servers. ServerGuide goes beyond mere hardware configuration by assisting with the automated installation of the Windows 2000 and 32-bit Windows Server 2003 operating systems, device drivers and other system components, with minimal user intervention. (Selected drivers are also included for support of Novell NetWare, Red Hat Linux and SuSE Linux.) This focus on deployment helps customers reduce both their total cost of ownership and the complexity that administrators and technical personnel face.

Additional services include hardware warranty upgrades and factory-installed Product Customization Services (PCS), such as asset tagging, hardware integration, software imaging and operating systems personalization.

IBM offers extensive technical support by phone and via the Web. Support options include links to forums/newsgroups, problem submission, online shopping support, service offerings, device drivers for all IBM product lines, software downloads and even upcoming technical seminar worldwide schedules and registration. Also available are remote installation, configuration and usage support for both xSeries hardware and software, as well as onsite custom services to give customers the level of expertise they require.

IBM options for ^systems let customers take their servers to a higher level

Make sure that customers know they can rely on ^options to supply a comprehensive solution for their business needs. Options help them create an optimized server system to meet their data protection, storage and availability needs. Every IBM option is designed and tested for peak performance and flexibility, helping to maximize the customer’s return on investment. The combination of ^systems and options lets customers keep their fingers on the pulse of their e-business.

Processors — The AMD Opteron processor provides power, speed, a large cache, integrated memory controller and HyperTransport Technology. A 1MB L2 cache running at the full processor clock rate combined with an integrated memory controller results in reduced memory latency and speeds the movement of data through the processor and I/O devices. (Note: System performance depends not only on the number of processors in the server but also on the power and functionality of each processor.) Let customers know that adding a second processor may be a cost-effective way to achieve significant performance improvements. Unlike most processors, adding additional Opteron processors actually increases processor-to-memory bandwidth.

Memory — Memory is a significant factor in application performance. Adding more memory to a server is one of the most effective ways to increase application performance.

Hard Disk Drives — IBM hard disk drives help customers improve the transaction and cost performance of their servers. The choice of drives can be a critical aspect of maximizing the I/O throughput of the system. IBM Ultra320 SCSI hard disk drives are available for the e325 with capacities up to 73.4GB at 15,000 RPMs and up to 146.8GB at 10,000 RPMs. IDE (ATA-100) hard disk drives are available with capacities up to 120GB at 7,200 RPMs.

ServeRAID Controllers — Servers using RAID technology allow companies to build a reliable foundation for business-critical computing. IBM ServeRAID technology allows an array consisting of multiple physical hard disk drives to be treated as one logical drive. ServeRAID technology also allows data to be stored redundantly, across multiple hard disk drives— enhancing both the integrity and the availability of the data. Optional ServeRAID controllers support nine RAID levels: 0 (striping), 00 (spans multiple arrays), 1 (mirroring), 10 (mirroring and striping), 1E (enhanced mirroring, supporting odd numbers of drives), 1E0 (enhanced mirroring with striping), 5 (striping with parity), 50 (striping across multiple RAID 5 arrays) and 5EE (enhanced RAID 5 with hot-spare drive). (Note: RAID 5EE is an improved version of RAID 5E, with up to 500-700%faster array rebuild times.)

And because IBM ServeRAID controllers can help significantly improve data transfer rates, this technology is extremely effective when implementing demanding, transaction-oriented applications. By employing the advanced fault tolerance of IBM ServeRAID technology, companies can effectively implement networked business systems that require large amounts of storage space for data and applications that must be available for their businesses to continue operating.

The family of ServeRAID-4 (Ultra160) and ServeRAID-6 (Ultra320) SCSI controllers offers enhanced performance and the ability to add external storage capacity up to 4.1TB (28 x

325 specifications

The IBM 325, introduced in the early 1970s, was a notable member of IBM's family of computer systems that aimed to improve business efficiency and computational capabilities. It was part of the System/3 series, designed for small to medium-sized businesses that required a robust yet manageable computing environment. The IBM 325 is often recognized for its versatility, user-friendly operation, and advanced technologies for its time.

One of the main features of the IBM 325 was its modular design, which allowed businesses to expand their systems as their needs grew. This flexibility made the IBM 325 appealing for various industries, enabling organizations to tailor their computing resources to fit specific requirements. The system supported a range of input and output devices, enhancing its functionality and making it adaptable for different business processes.

The IBM 325 was equipped with a powerful processor that provided efficient data processing capabilities. It supported batch processing, enabling businesses to handle large volumes of transactions effectively. The system could manage multiple users simultaneously, making it suitable for environments where several operations needed to be performed at once.

One of the standout technologies used in the IBM 325 was its magnetic core memory, which ensured fast access and reliable data storage. This memory type was known for its durability and performance, characteristics crucial for business operations that required constant uptime and quick data retrieval. Additionally, the system utilized advanced disk storage technology, allowing users to maintain significant data sets without the risk of loss or corruption.

Another important aspect of the IBM 325 was its software ecosystem. It supported various programs tailored to accounting, inventory management, and data processing. The software was designed to be intuitive, ensuring that employees could quickly adapt to the system without extensive training. This user-friendly interface contributed to smoother business operations and increased productivity.

In summary, the IBM 325 was a significant asset for companies in the 1970s, combining modular design, advanced processing power, reliable memory technology, and an easy-to-use software environment. Its ability to adapt to the needs of growing businesses while offering efficient solutions made it a cherished tool in the world of computing.
