ok... we have done a Sun implementation using Cisco Local Director Product... using JSP/Java.. works fairly easily and has some stateful data exchange... all home rolled... the Cisco products are dated and expensive.. interface doesn't leave you warm and friendly feeling.... the cost is quite high... and support can be lacking... good if you want to be geeky and waste lots of time... too much of what we asked for was a let me check sort of workaround...
We have two Hypeflow load balancing switches we utilize on occasion which are nice.. 15k per unit original price point... they never let us down... Experimenting with an appliance from Phobos... nice looking unit with 4 ports... and cross connect for interconnecting several of them... about a $3500 price point... KISS interface.... looks promising for small client work... I did a bunch of comparison shopping about 14 months ago of products... Like the looks of the F5 devices... they aren't cheap either...Foundry makes some nice gear and are originally switching people so they get the throughput and multiple interface and backplane piece real good... Cost is high like the rest... We checked out a piece of software from resonate... like a peer to peer distributed sort of system to control traffic redirection... was per server cost and there were some voids in places... seemed interesting enough... Me personally, I use a series of monitors internal and external to monitor things and send off notices if something goes offline... We have had 3 or front ends for a project running... nothing too big... when a bug or problem is/was detected we pull the DNS entry for the server from the available pool... if you are creative you can script things to edit the DNS entries in this case... of course our DNS servers have a 1 minute max lag time... which might not cut it for your product needs... Overall, the DNS solution I think is by far the best... unless you have a compelling story and a nice bankroll to throw at things... The Phobos unit is quit nice and performs well... its issue from my end is port density... Port density is big on my end as I typically wire boxes with quad cards to multiple switches.. lots of redundancy in the paths to avoid traffic or outage... -paris -----Original Message----- From: Neil H.
