5: Advanced Severboard Setup
• X8 = 2GB/s maximum transfer rate in each direction
PCIe Gen2 supports the following maximum bandwidths per slot:
• Gen2 PCIe runs at 5.0 GT/s (GT/s = GigaTransfers per second)
• Supports a maximum of 500 MB/s/lane
• X4 = 2GB/s maximum transfer rate in each direction
• X8 = 4GB/s maximum transfer rate in each direction
Installing PCI-X cards
There are three PCI-X slots: slots 1 and 2 share a single bus, slot 3 has a dedicated bus. The
maximum bandwidth, if both slots 1 and 2 are filled, is 1024 MB/s for both slots combined.
If either of the RAID options are selected, then slot 1 will not be available. The remaining two
PCI-X slots are equal. For consistency, fill slot 2 first.
If the RAID options are not selected, then all three PCI-X slots will be available. Slot 3 will each
support 1024 MB/s, but slots 1 and 2 share a single bus and therefore the total bandwidth available
to both slots is 1024 MB/s. When slotting PCI-X card, make sure to place the highest bandwidth
card in slot 3.
Installing PCIe cards
Use the following guidelines:
• Install Gen2 PCI cards in slots 4 and 6. Fill slot 4 first then slot 6.
• Install Gen 1 PCI cards in slot 5.
Power Supply
The default configuration is a single 720 watt power supply. The single power supply is slotted in
the top power bay slot. A second (redundant) 720 watt power supply can be added to the server in
the lower slot.
A dummy power supply must be installed in the lower power bay when the server is configured
with a single power supply.
