1-10 Cluster SE300 and SL30 0 Platform Guide
Adding Peripherals Required for PowerEdge 8450 Cluster Nodes
WARNING: Hardware installation should be p erformed only by trained
service technicians. Before working inside the system, see the safety
instructions in your PowerEdge System Information document to avoid a
situation that could cause serious injury or death.
The following list provides PCI slot assignment information for the system’s PCI
buses, RAID controllers, NICs, and DRAC.
•PCI buses
— PCI bus 1: PCI slots 1 and 2 are 64-bit, 33-MHz.
— PCI bus 2: PCI slots 3 through 6 are 64-bit, 33-MHz.
— PCI bus 3: PCI slots 7 and 8 are 64-bit, 33/66-MHz.
— PCI bus 4: PCI slots 9 and 10 are 64-bit, 33/66-MHz.
•RAID controllers
— Install the RAID controller for the server’s internal drives in PCI slot 1.
— Install additional RAID controllers in any available 64-bit, 33-MHz or 32-bit,
33-MHz PCI slot.
— If you use multiple RAID controllers and there are available slots, Dell
recommends installing the RAID controllers on separate 64-bit PCI buses to
balance the load on the system.
•NICs
— NICs can be installed in a ny available PCI slot.
— Dell recommends that Giganet cLAN adapters be installed in 64-bit slots.
•DRAC
— If you are currently using a DRAC or plan to use one in the future, install it in
PCI slot 2.
NOTE: To make sure that the SCSI or RAID controller attached to the boot drives ini-
tializes first, you might have to change the scan order of the PCI bus, if the system
BIOS supports this option, or change the order of the RAID, NIC, and DRAC. Perform-
ing these tasks ensures that the Windows operating system numbers the boot drives
in the proper sequence.
