Intel® Server Board SE7501WV2 TPS

Configuration and Initialization

The ZCR add-in cards leverage the on-board SCSI controller along with their own built-in intelligence to provide a complete RAID controller subsystem on-board. The riser card and baseboard use an implementation commonly referred to as RAID I/O Steering (RAIDIOS) specification version 0.92 to support this feature. If either of these supported RAID cards are installed, then the SCSI interrupts are routed to the RAID adapter instead of to the PCI interrupt controller. Also the IDSEL of the SCSI controller is not driven to the controller and thus will not respond as an on-board device. The host-based I/O device is effectively hidden from the system.

4.7Ultra320 SCSI

The SCSI version of the SE7501WV2 server board provides an embedded dual-channel SCSI bus through the use of the Adaptec* AIC-7902W SCSI controller, which is capable of supporting up to 132 MB/sec SCSI transfers. The AIC-7902W controller contains two independent SCSI controllers that share a single 64-bit, 100-MHz PCI-X bus master interface as a multifunction device, packaged in a 456-pin BGA.

Internally, each controller is identical and is capable of operations using either 16-bit SE or Low- Voltage Differential (LVD) SCSI providing 40 MBps (Ultra-wide SE), 80 MBps (Ultra 2), 160 MBps (Ultra 160/m) or 320 MBps (Ultra 320/M). Each controller has its own set of PCI configuration registers and SCI I/O registers. The SE7501WV2 server board supports disabling of the on-board SCSI controller through the BIOS Setup menu.

The SE7501WV2 server board provides active terminators, termination voltage, a re-settable fuse, and a protection diode for both SCSI channels. By design, the on-board termination will always be enabled. No ability will be provided to disable termination. Each of the two SCSI channels has a connector interface. Channel A is an external high-density connector located on the back of the board, and Channel B is a standard 68-pin internal connector.

The Adaptec* AIC-7902W SCSI controller adds a feature called Integrated SCSI

mirroring/striping also know as HostRAID1. Integrated SCSI mirroring/striping offers an entry- level Raid functionality for reliable performance and fill data protection for storage systems. HostRAID supports the following features:

•Boot array support

•Support for TAID 0 and DATA1 with Microsoft* Windows* operating systems

•RAID configuration and management utility in the system BIOS.

4.8ATA-100

The ATA-100 version of the SE7501WV2 server board provides an embedded dual channel ATA-100 bus through the use of the Promise Technology* PDC20277 ASIC. The PDC20277 ATA-100 controller contains two independent ATA-100 channels that share a single 32-bit, 33- MHz PCI bus master interface as a multifunction device, packaged in a 128-pin PQFP.

The ATA-100 controller supports the following features:
