5. Plug the controller firmly into an available 32-bit or 64-bit PCI slot so

that the controller’s external connectors can be accessed through the
access port. Use the retaining screw to secure the controller by its
mounting bracket (Figure 2-2).

Figure 2-2. Plugging the eXtremeRAID 2000 into a PCI Slot

Note

Although the eXtremeRAID 2000 controller will
operate very well in a 32-bit PCI slot, a 64-bit PCI slot
(if available) is recommended for optimal
performance. If the system board contains both 32-bit
and 64-bit PCI slots, the 64-bit slots are longer.

6. On a static-free surface, lay out the drives that will be used with this

controller and arrange the drives by channel. For example, all Channel
0 drives should be grouped together, all Channel 1 drives should be
grouped together, and so on.

For optimal performance, distribute the drives equally across the SCSI
channels and select the maximum data transfer rate supported by the
drives.

Note

If you plan to use both narrow and wide SCSI devices
on the eXtremeRAID 2000, make sure the narrow and
wide devices are on separate channels. If LVD-
capable drives and single-ended drives are installed on
the same channel, all drives on the channel will
operate as single-ended drives, and the bus length will
be limited to the single-ended bus length specified in
Table 2-2.
