| Q1. |
What is the NC510F? |
| A1. |
The NC510F is single port, x8 PCI Express multifunction 10 Gigabit Ethernet adapter meeting the IEEE 10GBASE-SR fiber optic standard. Along with its NC510C CX4 copper counterpart, it offers the greatest bandwidth available for ProLiant servers in a single Ethernet network adapter.
|
|
| Q2. |
How is the NC510F different from other NC-series ProLiant network adapters? |
| A2. |
The NC510F is a 10 Gigabit Ethernet adapter providing 10,000 Mbps ideal for a host of demanding applications meeting the needs of the next generation datacenter. With the planned accelerated iSCSI, RDMA, and TOE multifunction capabilities for both Windows and Linux, the NC510F provides LAN, SAN, a cluster communications over a single connection.
|
|
| Q3. |
What network controller is used in the NC510F? |
| A3. |
The NC510F utilizes the NETXEN NX2031 controller.
|
|
| General |
| Q1. |
What ProLiant servers support the NC510F? |
| A1. |
The NC510F is supported on many but not all ProLiant rack-mountable servers. Check the NC510F Quickspecs for the current list.
|
|
| Q2. |
Can ProLiant Teaming be used with the NC510F? |
| A2. |
Currently, the NC510F does not support ProLiant teaming. However, a future firmware upgrade is planned to provide this capability.
|
|
| Q3. |
Although the NC510F is a x8 PCI Express adapter, can it be used in x1 and x4 PCI Express slots? |
| A3. |
The NC510F can be used in either x4 or x8 PCI Express slots, although x8 will provide the optimal performance. PCI express x1 slots are not supported. The adapter automatically autosenses between x4 and x8 slots.
|
|
| Q4. |
Is the NC510F supported in full height or half height PCI Express slots? |
| A4. |
The NC510F supports both full height and half height PCI Express slots. The NC510F is a low-profile adapter with full height bracket installed and low profile adapter included in the kit.
|
|
| Q5. |
How many NC510F adapters are supported per ProLiant server? |
| A5. |
The maximum number of NC510F adapters supported per server is equal to the maximum number of available x4 and x8 PCI Express in the server.
|
|
| Multifunction capability |
| Q1. |
Why is the NC510F called a "multifunction" network adapter? |
| A1. |
The NC510F provides capability for accelerated networking, storage networking and clustering in a single, all-in-one device, in much the same way that HP multifunction printers offer printing, scanning and copying in a single, all-in-one device. The NC510F is single card operating over one cable yet providing multiple functions. The multifunction features are planned for near-term releases.
|
|
| Q2. |
Will there be an extra cost for the planned upcoming multifunction features? |
| A2. |
No; the NC510F planned accelerated iSCSI, RDMA, and TOE multifunction features will be available as free firmware upgrades.
|
|
| Q3. |
What is TOE? |
| A3. |
TOE stands for TCP/IP Offload Engine. TOE moves the processing of data in the TCP protocol stacks from the server CPU to the network adapter, freeing CPU cycles for other work. Traditionally TCP offload technologies such as checksum offload, segmentation offload, and large send offload deal with specific elements in the driver suite; whereas TOE offloads the TCP protocol stack.
|
|
| Q4. |
What is RDMA? |
| A4. |
RDMA (Remote Direct Memory Access) is the ability of one computer to place information from its memory directly into another computer's memory with minimal demands on memory bus bandwidth and CPU processing overhead. RDMA requires that an RDMA-enabled network adapter be installed at both ends of the wire.
|
| Q5. |
What is iSCSI and how does this differ from accelerated iSCSI? |
| A5. |
iSCSI (Internet Small Computer Serial Interface) allows block storage access over TCP/IP. The Accelerated iSCSI offloads the iSCSI software to the hardware for improved iSCSI system performance.
