SPARC S7-2L servers support the Oracle 3.2 TB NVMe SSD as a boot device.
An Oracle PCIe Switch Card is not required in a four NVMe drive configuration. The switch function is included in the motherboard. The SPARC S7-2L Server can support three Oracle PCIe Switch Cards. Additional Oracle PCIe Switch Cards are required to support backplane configurations with more than four NVMe drives.
