Oracle^® Server X8-2 Service Manual

PCI 64 Bit Resources Allocation

Enable (default) or disable 64-bit capable devices to be decoded in the 4G address space. This setting is available only if the system supports 64-bit decoding.

Maximum Payload

Set the Maximum Payload of the PCI Express device or allow the System BIOS to select the value.

Auto (default)/128 Bytes/256 Bytes/512 Bytes/1024 Bytes/2048 Bytes/4096 Bytes

Maximum Read Request

Set the Maximum Read Request of the PCI Express device or allow the System BIOS to select the value.

Auto (default)/128 Bytes/256 Bytes/512 Bytes/1024 Bytes/2048 Bytes/4096 Bytes

PCIe Hot-Plug Support

Enable (default) or disable the OS to support PCIe hot-plug.

VT-d

Enable (default) or disable Intel Virtualization Technology for directed I/O (VT-d) by reporting the I/O device assignment to VMM through DMA remapping reporting (DMAR) Advance Configuration Power Interface (ACPI) tables.

ACS

Enable programs Access Control Services (ACS) to toggle peer to peer transactions between PCIe devices. Disable (default) programs ACS to only chipset PCIe root ports bridges for IOMMU separation.

SR-IOV Support

Enable (default) or disable Single Root I/O Virtualization (SR-IOV) to configure devices into multiple virtual devices that can be used on virtual OS installations. If supported by the hardware and set to enabled, all devices on the system that are SR-IOV capable are configured to support SR-IOV and I/O resources are allocated to the device as normal. If set to disabled, I/O resources are not allocated to the device.

ARI

If Alternate Routing ID (ARI) is supported by the hardware and set to enabled (default), devices are permitted to locate virtual functions (VFs) in function numbers 8 to 255 of the captured bus number, instead of normal function numbers 0 to 7.

Intel IOAT

Enable (default) or disable Intel I/O Acceleration Technology (I/OAT) devices to offload memory copies from the processor using direct memory accesses (DMA) to improve performance on I/O transactions.

DCA Support

Enable (default) Direct Cache Access (DCA) for a capable I/O device, such as a network controller, to place data directly into the CPU cache, reducing cache misses and improving application response times.

Slot 1 Hardware Configuration

Displays and provides options to configure hot-plug functionality or FM10K bifurcation for the PCIe HBA slot. FM10K bifurcation allows an Ethernet card to appear as multiple interfaces.

PCIE Slot Hardware Configuration

Enable or disable hot-plug or FM10K bifurcation, which allows an Ethernet card to appear as multiple interfaces.

Slot 2, Slot 3, and Slot 4

See Slot 1 description.

NET0

Displays and provides options to change the internal device settings.

Enable (default) or disable PCI-E UEFI Driver. If set to enabled, UEFI Driver for the card executes as normal. If set to disabled, UEFI Driver for the card is not copied into memory and the execution of the UEFI Driver is inhibited.

NET1 and NET2

See NET0 description.

Slot 1

Displays and provides options to change the settings of the devices in PCIe slots.

Disable or enable (default) IO

Enable (default) or disable PCI-E UEFI Driver. If set to enabled, UEFI Driver for the card executes as normal. If set to disabled, UEFI Driver for the card is not copied into memory and the execution of the UEFI Driver is inhibited.

Enable (default) or disable DDIO Use_Allocating_Flow_WR for this PCIe slot.

Slot 2, Slot 3, and Slot 4

See Slot 1 description.
