This IBM Redbook introduces you to this new technology and other significant functions like high speed loop (HSL) and hot plug capability. HSL is the new bus architecture that connects systems and expansion units. Learn how this technology is implemented, and see how it differs from the existing SPD optical bus system. Hot plug capabilities increase the availability of systems. See how you can swap (exchange) components while the system is still up and running.

Planning your upgrade from an existing iSeries server to a new model is always a significant task. This redbook also provides example upgrade scenarios to assist with your planning. It examines and explains new upgrade functions, such as load source migration. And, to leverage your investment in iSeries hardware, V4R5 provides a migration tower solution, which is discussed in detail.
