This powerful, highly integrated systems-management software solution is built on industry standards and designed for ease of use. Exploit your existing enterprise or workgroup management environments and use rich security features to access and manage physically dispersed IT assets more efficiently over the Internet. It can potentially help reduce costs through: Reduced downtime Increased productivity of IT personnel and end users Reduced service and support costs IT administrators can view the hardware configuration of remote systems in detail and monitor the usage and performance of critical components such as processors, HDDs, and memory. IBM Director can be extended with optional add-ons for advanced server management, deployment, and software distribution. All of these tools smoothly integrate into IBM Director for consistent look-and-feel and single point of management while taking advantage of the IBM Director monitoring, scheduling, alerting, event management, and group management capabilities. Optional add-ons The IBM Director Server Plus Pack is a collection of five tools with predictive and autonomic capabilities that help deliver optimal server performance and high availability. The five tools include capacity manager, software rejuvenation, active PCI manager, system availability, and rack manager. Application Workload Manager extends IBM Director to enable the control of how multiple applications use server resources and protect against unexpected resource contention. Remote Deployment Manager is an effective tool for the initial deployment phase of a system's lifecycle with the ability to remotely send out complete software images for installation in a preboot environment. Software Distribution Premium Edition enables you to create and distribute software packages to systems on your network, saving travel and labor costs. IBM Director also enables integration into leading workgroup and enterprise systems management environments, via its Upward Integration Modules. You can access advanced management capabilities built into xSeries servers from: Tivoli Enterprise and Tivoli NetView Computer Associates CA Unicenter TNG HP OpenView Microsoft SMS BMC Patrol NetlQ For more information about IBM Director, refer to Software Announcement 202-246, dated September 24, 2002. Remote Deployment Manager (RDM) for BladeCenter BladeCenter can use RDM, which enables the configuration and deployment of BladeCenter HS20 blades within a single BladeCenter. This highly flexible and powerful tool enables you to deploy system images that include the operating system and configuration detail to one or more blade servers at one time from an IBM Director console on the network. With RDM you can: Add instructions for loading firmware or specific operating systems Deploy multiple blade servers in a BladeCenter at one time Store various images on the RDM server for target server installations Restore initial or incremental disk images locally with a keystroke Drop and drag to deploy images BladeCenter management module Use the management module in the BladeCenter to manage the BladeCenter and obtain vital system information about your installed BladeCenter HS20 servers. The management module communicates with the blade servers within the BladeCenter via an RS-485 intermanagement network. This network relays vital information about individual blade servers such as: Temperature Voltages Power supply status Memory status Fan status HDD status Error and status log You receive status and control for all blade servers within the BladeCenter. You can shut down and restart any blade server from anywhere on the network to help save time and costs associated with travel to the actual installation. These manageability functions are provided through a self-contained Web page, creating an easy and familiar way for administrators to monitor, control, and maintain highly available BladeCenter installations. The BladeCenter chassis ships standard with one KVM/management module. An optional BladeCenter redundant KVM/management module provides BladeCenter with even higher levels of resiliency. While in the chassis, the second module is in passive, or standby, mode. If the active or primary module faults, the second module is automatically enabled with all the configuration settings of the primary module. You benefit from seamless remote management and connectivity to the BladeCenter chassis for your most critical applications. Accessibility by people with disabilities None.
