Once your session is configured, click Connect and, assuming there is no operating system currently running, you should see POST messages or the EFI Boot Manager menu. Tip: If you are running Linux, you can redirect the console messages to the serial port. For more information about this feature, refer to the "Console messages over the serial port" section in Chapter 4 of the publication Linux on Itanium 2. 3.3 Storage considerations When you are planning the storage configuration to accompany the x450, there are important performance and sizing issues that need to be considered. The two internal hot-swap 1" drive bays will typically be used for operating system installation. We recommend these drives be configured as a two-drive RAID-1 array to provide a higher degree of system availability. Drives up to 15,000 RPM and the converged tray design are supported. To configure RAID-1, you must use the internal LSI controller that is provided onboard. Restriction: ServeRAID adapter is supported on external disks only. For internal disks, you must use the internal LSI controller. Typically the x450 will be attached to an external disk enclosure for data storage requirements. Some of the supported IBM storage options are: SCSI RAID adapters and storage enclosures Fibre Channel adapters and Storage Area Networks (SANs) Network Attached Storage (NAS) SCSI over IP (iSCSI) IBM Enterprise Storage Server™ (ESS) ESCON® connectivity to a zSeries server Note: You can also add as an option an LS-120 diskette drive that can be used to upgrade the firmware or the EFI version. Please note that no diskette drive is provided with the default configuration, and that this solution is not supported. 3.3.1 xSeries storage solutions This section discusses some of the available xSeries storage solutions and related technologies, as well as tape backup and performance considerations. 56 IBM ^ xSeries 450 Planning and Installation Guide
