Hardware Specifications and Features Note: Compatibility refers only to how data and RAID configuration information are written to the hard disks. Compatible controllers have the same data file format. 3.5 Optional Features The SRCU42L supports the following optional features as described in the Software Guide: • PCI Hot Plug • Configurable SCSI parameters 3.5.1 PCI Hot Plug The SRCU42L adapter supports PCI Hot Plug under the following OS's: • Windows 2000 Advanced Server SP3, Windows 2000 Server, Windows 2000 Professional • Novell NetWare 5.1 SP2a • Novel NetWare 6.x This IIR controller supports the PCI Hot Plug functionality for the Hot Replacement of an adapter. Hot Replacement assumes that the drivers for the adapter being replaced are already loaded. 3.5.2 Configurable Disk Drive SCSI Parameters When a SCSI hard disk drive is initialized the first time by the RAID controller, its SCSI parameters are automatically set to their optimal settings. Most settings are set automatically and can not be configured manually. To view or configure disk drive SCSI parameters from the Storage Console, choose Advanced Setup Æ Configure Physical Devices Æ Select Physical Drive Æ SCSI Parameter/Initialize. Table 3-4. Configurable Disk Drive SCSI Parameters Parameter Setting/ Value Configuration Description Synch. Transfer Enabled / Disabled Automatic Synch. Transfer Rate Speed (MB/sec) Automatic This setting when enabled allows the controller to operate in synchronous transfer mode Allows for the setting of the speed for the SCSI hard disks (up to 320 MB/sec for U320 drives). No matter the setting, the SCSI bus will negotiate the fastest speed up to this setting. Lowering the setting will force the disk drive to transfer at the lower speed. 26 Hardware Installation and User's Guide
