This IBM® RedpaperTM publication illustrates how the IBM WebSphere DataPower Integration Appliance XI50 for zEnterprise provides a secure, fast, cost-effective, easy-to-manage, all-in-one enterprise application integration solution. On top of all the benefits that the DataPower XI50 and XI52 already provide, incorporating the DataPower XI50z into zEnterprise also provides a number of additional benefits: - Exploitation of the high-speed intraensemble data network (IEDN) connecting the zEnterprise Blade Extension (zBX) with the zEnterprise central processor complex (CPC), either a zEnterprise 196 (z196) or zEnterprise 114 (z114) - Secure incorporation of the DataPower XI50z appliance into a virtual local area network (VLAN) on the zBX - Unified management of the DataPower XI50z, along with other blades and optimizers using a common management tool - A centralized computing model, resulting in more efficient use of floor space, lower energy costs, and a lower total cost of ownership (TCO) The DataPower XI50z provides a variety of powerful integration scenarios specifically for older mainframe applications, making it a natural choice to include the appliance in your centralized zEnterprise server. This publication is intended for potential and actual users of the DataPower XI50z.
