Suggestions on fiber Gigabit NICs

[javier.iglesias at freesurf.ch]

Hi all,

To cope with some network bottleneck problems leading to calculation 
crashes, we envisage to migrate our 18-nodes' (bi-AMD 1600+/Tyan Tiger 
MP/FastEthernet/Scyld 27-b8) master to Gigabit. 

I would like to get your feelings/experiences on two fiber Gigabit 
NICs :

1) Netgear GA-621
-> http://www.netgear.com/product_view.asp?xrp=1&yrp=1&zrp=106

2) 3Com 3C996-SX
-> 
http://www.3com.com/products/en_US/detail.jsp?tab=features&pathtype=purchase&sku=3C996-SX


We have a really nice ethernet Extreme Networks Summit 48 switch 
-> http://www.extremenetworks.com/products/datasheets/summit24.asp
that offers 2 fiber Gigabit ports we want to push to work :)

Any other suggestion ? want to share comments ?

Thanks in advance for your help !
