Application Workload Manager extends IBM Director to enable the control of how multiple applications use server resources and protects against unexpected resource contention. Remote Deployment Manager is an effective tool for the initial deployment phase of a system's life cycle 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 provides integration into leading workgroup and enterprise systems management environments via its Upward Integration Modules. This enables the advanced management capabilities built into xSeries servers to be accessed 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 image 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 comes standard with one KVM/management module. An optional BladeCenter redundant KVM/management module can provide 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 fails, 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. Back to top   Product Positioning This BladeCenter HS20 offering is positioned as one of the highest-density servers of the IBM eServer line. It represent a new approach to the deployment of application servers where two-way, SMP-capable Xeon processing, high-availability design, systems management, and easy setup features are combined in an extremely dense package. The BladeCenter in just 7 U of rack space contains up to 14 blade servers and two 2,000-watt power supplies to provide the necessary I/O network switching, power, cooling, and control panel information. When compared to most Intel processor-based 1 U high servers, the BladeCenter can support twice the amount of processing power in the same rack space. The BladeCenter and BladeCenter HS20 blade require less space and power resources because of the high-density design, reduced power requirements, and single environment systems management. This is an extremely important consideration for: Large enterprises Application service providers Scientific and technical computing businesses It is an excellent fit for applications such as: Lotus Notes Microsoft Exchange Linux clusters Back to top   Models Model Summary Matrix Model Description Contains 3EU BladeCenter chassis Cisco Ethernet Switch Module Customer Setup (CSU) This product is designated Customer Setup.
