welcome to the club migz :->
but im looking forward this coming switch-off this coming july 30 to august
3 because there is a marketing and technical superiority between altheon and
foundry :-> but of course the LVS community claims that they are superior
than the two above. :-> so let us wait this switch-off results.
for more info this coming switch-off:

for fritz,
if you are looking for a load balancer otherwise known as layer 4
switch, you have to know your layer 8 and layer 9 first. these layers
popularly known as budget and politics respectively.
acquiring a layer 4 switch iron is very expensive but you have the
alternative using LVS. aside from these, there are DNS round robin and LSNAT
(load sharing network address translation).the first two i mentioned have a
L7/L4/L3 health-check features while the last two dont have.
but if you want to know what other commercially products since that is what
your top management wanted, here are the lists that i know of:
Switches
Alteon AceDirector Switch
ArrowPoint ContentSmart Switch
BlazeNet AppSwitch
Foundry ServerIron Switch
HolonTech HyperFlow Switch
Extreme Networks Summit4 Switch
Hardware
Cisco's Local Director
Cisco Distributed Director
HydraWeb Hydra900
F5 Labs BigIP Server Array System
