1-10 Dell PowerEdge Cluster Platform Guide
Peripherals for PowerEdge 6400 and 6450 Cluster Nodes
The following list provides PCI slot assignment information for the system’s PCI
buses, HBAs, and the DRAC 2.
• PCI buses
— PCI bus 0: PCI slot 1 is 32-bit, 33-MHz.
— PCI bus 1: PCI slots 2 through 5 are 64-bit, 33-MHz.
— PCI bus 2: PCI slots 6 and 7 are 64-bit, 33/66-MHz.
• HBAs
— For dual HBA configurations, Dell recommends installing the HBAs on sepa-
rate PCI buses (PCI buses 1 and 2) to balance the load on the system.
• DRAC 2
— If you are currently using a DRAC 2 or plan to use one in the future, install it
in PCI slot 1.
Peripherals for PowerEdge 8450 Cluster Nodes
The following list provides PCI slot assignment information for the system’s PCI
buses, RAID controllers, HBAs, and the DRAC 2.
• PCI buses
— PCI bus 0: PCI slot 1 and 2 are 64-bit, 33-MHz.
— PCI bus 1: PCI slots 3 through 6 are 64-bit, 33-MHz.
— PCI bus 2: PCI slots 7 and 8 are 64-bit, 33/66-MHz.
— PCI bus 3: 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.
• HBAs
— For dual HBA configurations, Dell recommends installing the HBAs on sepa-
rate PCI buses (PCI buses 2 and 3) to balance the load on the system.
• DRAC 2
— If you are currently using a DRAC 2 or plan to use one in the future, install it
in PCI slot 2.
