Adapter configurations 26
Property Parameter
Status Ring Size A descriptor ring size (queue size) for the status given by the network adapter to the
driver. Setting this value too low will impact the throughput because the network
adapter will start dropping packets. This parameter only affects receive operations
and does not affect transmit operations.
• Default: 8192
• Value: 1024/2048/4096/8192/16384/32768
Transmit IP Checksum
Offload
Enables the transmit IP checksum offload.
• Default: Enabled
• Values: Enabled/Disabled
Transmit Ring Size A descriptor ring size (queue size) for the transmit commands given by the driver to
the network adapter. It describes how many transmit operations can be given by the
host/driver to the network adapter at one time without overflowing the transmit
queue. Each of the entries in this queue describes one transmit/send operation by
the driver.
• Default: 1024
• Value: 1024/2048
Transmit TCP/UDP
Checksum Offload
Enables the transmit TCP and transmit UDP checksum offload.
• Default: Enabled
• Values: Enabled/Disabled
Vlan Id Sets the VLAN ID for this interface (also exposed through the standard OID). QoS
Packet Tagging must be enabled or the VLAN ID parameter is ignored.
• Default: 0 (no VLAN)
• Range: 0 – 4095
If multiple VLANs are set, the value is set to 0 (zero) and an intermediate driver is
used to set each VLan.
Configuring multiple NC510x PCIe 10 GbE adapters
Multiple NC510x PCIe 10 GbE stand up adapters can be configured in a single system.
• Requirements—HP recommends installing 2 GB of system memory per 10 GbE port. Each NC510x
PCIe 10 GbE adapter installed must have a unique IP address assigned.
NOTE: Windows 32 bit may require the Physical Address Extension (PAE) option to utilize 4
GB or more of memory. PAE is a memory address extension that enables support of greater
than 4 GB of physical memory for most 32-bit (IA-32) Intel Pentium Pro and later platforms. For
more information, see PAE Memory and Windows information on the Microsoft
(http://www.microsoft.com
) website.
• Installing—Install additional NC510x PCIe 10 GbE stand up adapters in any empty PCI Express slot
on the system. In a Windows or Linux operating system, when the NC510x driver is installed, the
driver automatically loads for any additional NC510x adapters that are added.
• Enabling—Each adapter can be enabled independently. The user assigns an IP address to each
adapter in the system.
