RE: [IMail Forum] IMAIL 6.03 How do I Config to load balance behind a Cisco 6509

[John David M. Miller]

I would not use WLBS as you are correct, it does not currently support it. It could be accomplished via layer 4 using replicated databases on an NAS. MS has only tested SQL and NAS configs using Network Appliance boxes but it does not mean that it won't work with other NAS units, only that they will not support it. SQL does not support multiple SQL Servers accessing the same database so it does to my knowledge require replicated databases. I have not investigated the impact of the replication on the scalability yet.   We resell these types of equipment, in addition to using them in house so we will be testing different implementations of this in the near future.   I am more interested in verifying that IMail could be load balance using L4 and the above backend.   E-Mail off list if you have specific questions.   John Miller SAMnet [EMAIL PROTECTED]     -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of John Morrison Sent: Tuesday, May 02, 2000 7:34 PM To: [EMAIL PROTECTED] Subject: RE: [IMail Forum] IMAIL 6.03 How do I Config to load balance behind a Cisco 6509 John, The information I have seen on load balancing with WLBS makes no mention of the ability to work with sql server. I is to my information that ms does not provide a formal way to load balance SQL servers, only cluster If you can send me any info on this I would appreciate it.   Regards, John Morrison -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of John David M.

I am unsure if anyone is currently load balancing IMail.   Based upon your current direction I would recommend using the SQL cluster to access a Network Attached storage cluster. Response times and availability will be much higher. You mail data would also be stored on the NAS improving it's performance and reliability. This solution will also scale better.   Ideally, I would examine load balancing the SQL servers and not using the MS cluster at all. I am still investigating this option. I know that it is possible but have not worked all the details out yet.........   John Miller SAMnet [EMAIL PROTECTED]
