Oracle Server X5-8 requires a doublewide PCIe hot plug carrier extension for each installed Oracle Flash Accelerator F320 PCIe Card to facilitate air flow. The server PCIe cards are housed inside card carriers called DPCCs (dual PCIe card carriers, Mkt PN 710710). The DPCCs allow the cards to be hot serviced while the server is powered on.
To access a PCIe card, you must first remove its Dual PCIe Card Carrier (DPCC). One PCIe card can be installed in each DPCC. DPCCs do not allow the use of one adjacent PCIe slot. DPCCs are installed in odd numbered PCIe slots.
The following figure shows an example of a Dual PCIe Card Carrier (DPCC) that populates two PCIe slots for each Oracle Flash Accelerator F320 PCIe Card.
