Xen users - Jul 2009 - 10GB Ethernet for Xen - Intel, Solarflare, Mellanox, Which is best?

Hi All,

 

I''m trying to choose between 10Gb Ethernet cards for Xen. The trouble
is
I''m getting quite confused with all the different terms different
companies use to describe NIC''s virtualization support. Any ideas what
the differences are between these brands?

 

I am trying to sort a comparison table but will need some help:

Feature

Intel ET Series

Mellanox ConnectX

Solarflare

Receive Queues

64

32

?

Transmit Queues

32

?

?

PCI-E Version

2

2

1

Direct IO

No

No

Linux PV Only

Mac/Vlan per port

?

128

4096

IOAT and MSI-X

Yes

Yes

Yes

 

Does the Solarflare chip support multi-queue as well as direct IO? Any
other features I should be looking at?

 

Thanks,

 

Rob
