Choosing two 10GiGE cards

[rihad]

Hi there,

We think it's time to switch from two GiGE bce cards to 10GiGE.
According to http://www.freebsd.org/releases/7.2R/hardware.html
the 10GiGE cards listed below are supported on amd64. Anyone has 
personal experience using any of them them? Should I prefer drivers that 
support DEVICE_POLLING (actually, only ixgb as per "man polling")? I'll 
try to find out from the manufacturer how their own models differ from 
each other (all this LR/SR/CX4 stuff). Thanks.


[i386,amd64] The ixgb(4) driver supports the following cards:

     *      Intel PRO/10GbE LR Server Adapter
     *      Intel PRO/10GbE SR Server Adapter

[i386,amd64] The cxgb(4) driver supports 10 Gigabit and 1 Gigabit 
Ethernet adapters based on the T3 and T3B chipset:

     *      Chelsio 10GBase-CX4
     *      Chelsio 10GBase-LR
     *      Chelsio 10GBase-SR


[i386,amd64] The mxge(4) driver supports 10 Gigabit Ethernet adapters 
based on the Myricom LANai Z8E chips:

     *      Myricom 10GBase-CX4 (10G-PCIE-8A-C, 10G-PCIE-8AL-C)
     *      Myricom 10GBase-R (10G-PCIE-8A-R, 10G-PCIE-8AL-R)
     *      Myricom 10G XAUI over ribbon fiber (10G-PCIE-8A-Q, 
10G-PCIE-8AL-Q)

[i386,amd64] The nxge(4) driver supports Neterion Xframe 10 Gigabit 
Ethernet adapters listed in http://www.neterion.com/how/pricing.html.
