Gents Thanks for the pointers. I appreciate the replies. I had a look at the f5 site and those devices appear to do what i want and a lot more. Just one question though and excuse my ignorance.... Where would the load balancer actually sit ? At the ISP ? The sites are at two different physical locations with two seperate routers to the internet (one at each site). regards ----- Original Message ----- From: Ron Oglesby To: thin@xxxxxxxxxxxxx Sent: Monday, July 21, 2003 8:01 PM Subject: [THIN] Re: CSG and Multiple DMZ's Xactly Ron Oglesby Senior Technical Architect RapidApp Office 312.372.7188 Mobile 815.325.7618 email roglesby@xxxxxxxxxxxx -----Original Message----- From: Jensen, Jay [mailto:jjensen@xxxxxxxxx] Sent: Monday, July 21, 2003 1:55 PM To: 'thin@xxxxxxxxxxxxx' Subject: [THIN] Re: CSG and Multiple DMZ's Instead of two DMZ's why not use BIGIP. -----Original Message----- From: M [mailto:mathras@xxxxxxxxxxxxxxxx] Sent: Monday, July 21, 2003 1:45 PM To: Thin@xxxxxxxxxxxxx Subject: [THIN] CSG and Multiple DMZ's Hi Is anyone using multiple CSG servers split accross different DMZs to server the same Citrix Farm? Ive been presented with a possible DR scenario where a single Citrix Farm has two zones at two sites ( 1 zone at main 1 zone at DR )that are connected via 100 mbit link. Each site has a 2Mbit link to the internet and dedicated DMZs can be provided for the CSG/Nfuse servers. I was lookin at the possibilty of having CSG /Nfuse servers located in each DMZ but am looking for ways of ensuring that if one Internet pipe or the CSG/Nfuse servers fail , users will be redirected to other internet pipe & CSG/Nfuse servers. Is this feasible ? i was looking at simple DNS redirection but i dont think this will redirect if the CSG server fails. Am i making things too complicated or is there an elegant solution ? Thanks for your time. regards
