The IBM iSeries is IBM's mid-range server line, which used to be known as the AS/400 series. It is IBM's best-selling hardware range and is used by more medium and large enterprises than any other server line.
The latest IBM iSeries servers incorporate a host of technologies specifically designed to increase productivity by lowering total cost of ownership while increasing processing power and efficiency. iSeries systems are built around Power architecture processors. Power7 processors, the most recent revision, are a revolutionary advance on previous generations. They are available with 4, 6 or 8 cores each capable of four-way simultaneous multi-threading and with features such as the TurboCore mode and virtualization enhancements which make them particularly appropriate for businesses wishing to consolidate their legacy systems.
IBM iSeries servers, because of their increase in processing power relative to their initial cost and lifetime cost, allow for savings to be made in infrastructure deployment, maintenance, and growth. Their power means that fewer server units are needed to meet the current and ongoing requirements of a business, often reducing the amount of space needed for a company's IT infrastructure by half or more. Fewer servers means lower overheads in staffing requirements and frees up space for other projects.
iSeries systems incorporate IBM's Energy Scale adaptive energy management systems, which include dynamic voltage and frequency slewing and real-time adjustment of power use, reducing energy costs while being able to quickly scale up performance during periods of peak demand. TurboCore mode allows the processors to selectively shut down underutilized cores while increasing the clock speed and cache available to the remaining cores, decreasing energy use and increasing efficiency. Lower energy usage leads to less spending on power for the servers and also lowered requirements for cooling systems and their maintenance.
A major benefit of iSeries systems is their focus on leveraging virtualization technologies. Virtualization of systems running a company's databases, SAP software, CRM packages and other enterprise applications means that the hosting servers can be utilized to their full potential. Rather than having idle capacity on servers running one application, multiple guest virtual machines can be efficiently run on the same hardware. The productivity advantages here are obvious. Guest virtual machines require no hardware maintenance or space, they are able to be created, moved between physical hardware, and backed-up with ease.
When Staples, the American office equipment retailer, was looking for IT solutions to replace their legacy online retail infrastructure, they decided on iSeries Power7 systems. The switch replaced 35 older servers with 7 iSeries systems making space saving of 56 percent, reducing energy consumption by up to 65 percent, and maintenance requirements by 80 percent. Staples is now able to expand its online retail growth in the knowledge that their infrastructure will scale with their business. Staples reported that the reduced TCO of their systems was accompanied by the ability to implement improved e-commerce systems that increased page load times by 55 percent among other benefits, resulting in anticipated increases in their conversion rates and revenue
The IBM iSeries with Power architecture processors has enabled medium and large enterprises to significantly reduce their costs while increasing the power and efficiency of their operations, leading to across the board productivity increases.
