Oracle Server X5-8 requires a doublewide PCIe hot plug carrier extension for each installed Oracle Flash Accelerator F160 PCIe Card to facilitate air flow. Dual PCIe Card Carriers (DPCCs) do not allow the use of one adjacent PCIe slot. PCIe hot plug carrier extensions (Mkt PN 710710) 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 F160 PCIe Card.
