Oracle Server X7-8 requires a doublewide PCIe hot-plug carrier extension for each installed Oracle Flash Accelerator F640 PCIe Card v1 to facilitate airflow. Dual PCIe Card Carriers (DPCCs) do not allow the use of one adjacent PCIe slot. PCIe hot-plug carrier extensions (PN 710710) are installed in odd numbered PCIe slots.
The following figure shows an example of a hot-swappable Dual PCIe Card Carrier that populates two PCIe slots for each Oracle Flash Accelerator F640 PCIe Card v1.
