SPARC T7-4 Servers require a singlewide PCIe hot-plug carrier extension for each installed Oracle Flash Accelerator F640 PCIe Card v1 to facilitate airflow.
In SPARC T7-4 servers that have Oracle Flash Accelerator F640 PCIe Card v1s installed, you must install cards in slots 1/2/3/4/13/14/15/16 to avoid thermal concerns in the system.
SPARC T7 series servers support the Oracle Flash Accelerator F640 PCIe Card v1 as a boot device.
For more information about the servers, refer to the server documentation at https://www.oracle.com/goto/t7-4/docs.
