The SCSI version of the Intel
®
Server Board SE7500WV2 includes an embedded Adaptec AIC*-7899W dual function
SCSI controller that incorporates two independent Ultra160 SCSI controllers, both of which share a single 64-bit, 66-
MHz PCI bus master interface on the P64-B PCI segment.
•
Two physical connectors:
−
High-density external connector attached to SCSI channel A
−
68-pin internal connector attached to SCSI channel B
•
Each channel supports either 16-bit single-ended (SE) or low voltage differential (LVD) SCSI devices at speeds
ranging from 40 MBps to 160 MBps.
•
Mixing SE SCSI devices and LVD devices on the same channel forces the channel to operate in SE mode.
•
16-bit SE SCSI supports a maximum throughput of 40 MBps and also has a maximum end-to-end bus length of
6 meters per channel, as compared to 12 meters for LVD.
•
Active terminators are included onboard and cannot be disabled.
•
Each controller has its own set of PCI configuration registers and SCSI I/O registers. The registers can be disabled
through the BIOS setup menu.
•
Configure onboard SCSI device settings using the Adaptec SCSISelect* utility by pressing Ctrl+A at the Adaptec
device information display during boot up.
•
Integrated self-healing fuse device for physical SCSI bus included onboard.
