Configuring Fibre Channel HBAs on Separate PCI Buses
Dell recommends configuring Fibre Channel HBAs on separate PCI buses. While con-
figuring the adapters on separate buses improves availability and performance, this
recommendation is not a requirement.
The following list provides the PCI slot assignment information for the PowerEdge
8450 system PCI buses, RAID controllers, HBAs, and the Dell OpenManage Remote
Assistant Card (DRAC).
• 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 system’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, which includes PCI slots 7 through 10) to
balance the load on the system.
• DRAC
— If you are currently using a DRAC or plan to use one in the future, install it in
PCI slot 2.
Configuring PowerVault DPE and DAE Enclosure
Addresses
When adding a PowerVault DAE to a PowerVault DPE, each DAE must have a unique
enclosure address (EA). Be sure to set the EA of each enclosure attached to a
PowerVault DPE to a unique value.
See the Installation and Troubleshooting Guide for your PowerVault storage system
for more information on setting enclosure addresses.
