Re: 10GB Ethernet Cards

[DrFranken <midrange@xxxxxxxxxxxx>]

Easy there Rob, don't ever criticize IBM for supporting new function or 
feature! Just because it's not what you need doesn't mean it's not 
useful for others!  Have you purchased a 795 yet? No, me neither but I 
know there are customers out there using them.

Consider the customer who does occasionally push his 1G Line to the 
limit, his choice used to be a 10G line and that means 10G switches too, 
not an insignificant investment that! Instead 2, 3, 4 1G lines get a 
very decent performance bump for very small money, possibly none given 
the number of 1G cards out there. Then consider that the partition may 
be hosting several others. Done correctly the aggregate line is bridged 
to the internal VLANs with 802.1Q tagging keeping each partition 
separate but still using that aggregated link. Then as you say, it gives 
a bit of redundancy as well and it's simpler in several ways than 
virtual IPs.
