Table 2-1 Operating system support at x455 launch Operating system Support at x455 general availability: Windows Server 2003, Enterprise Edition 4-way (1 node) Supported 8-way (2 node) Supported 16-way (4 node) No1 Windows Server 2003, Datacenter Edition Supported Supported Supported Red Hat Linux AS 2.1 Red Hat Enterprise Linux 3.0 SUSE LINUX Enterprise Server 8.0 Supported Supported2 Supported No No Supported2 No Supported2, 3 No Notes: 1. Enterprise Edition supports a maximum of eight processors. 2. Support will be after the general availability (GA) of the x455. See: http://www.pc.ibm.com/us/compat/nos/matrix.shtml 3. Support approximately 30 days after GA. 2.4 Server consolidation With its scalability options, the x455 is ideally suited to server consolidation. Enterprise applications such as those used for large databases, enterprise resource planning (ERP), customer relationship management (CRM) and messaging/collaboration have traditionally been distributed across several servers. The x455 now allows you to consolidate these applications onto less hardware. Consolidation will allow business to centralize their business computing workloads and reduce cost, complexity, network traffic volumes, and management overhead. The x455 protects the investment you have already made by allowing you to expand to two then four nodes. Resources such as processors, memory, hard disks, network cards, monitors, and even CD-ROMs are accessible to the operating system and applications from all the nodes. Server consolidation has many interpretations and covers many areas. There is no single strategy or methodology that can be applied that will yield an exact outcome, as each environment is different. However, there are broad categories that may have particular importance where benefits can be realized. Below is a summary of some of the different types of server consolidation and the potential benefits. Chapter 2. Positioning 43
