RE: [IMail Forum] Imail High Availability Setup

Your Idea of a Dell NAS doesn't provide for HA, what if the NAS fails?  I do not remember clustering being an option for the Win Appliance OS. You would be better off looking at a soloution more like RaidZone's GangStor (http://www.raidzone.com/Products___Solutions/GangStor_Overview/gangstor_overview.html), which is fully redundant, and scaleable, I'm not sure how it handles file locks though, but, 6.06 seems to always write a lock file for all operations or rewrite the file name using a lock convention. Still not a bad Idea to have seperate spool and log directories for each server only sharing the message store.   Thanks, Chuck Frolick ArgoNet, Inc.    -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Randy Leiker Sent: Thursday, June 26, 2003 11:18 AM To: [EMAIL PROTECTED] Subject: Re: [IMail Forum] Imail High Availability Setup Len,   It's been a while since we've spoke.  Good to hear from you again & see that you're still on the Imail listserv here.  See my response below to your comments, in red: Randy Leiker  ( [EMAIL PROTECTED] ) Skyway Networks 816.221.1400  Ext. 100 Toll free: 1-800-538-5334 http://www.skywaynetworks.com What about having both Imail servers access a common storage pool via a NAS (network attached storage) appliance?  For example, some of the NAS devices I've learned about from Dell have a Windows OS on board that supposedly controls file locking.  Using gigabit Ethernet between the NAS & the Imail servers, I think that would potentially offer an adequate level of speed & prevent file collisions.    I'm thinking that a Windows powered NAS from Dell, using gigabit ethernet connectivity might be the answer for file collision management. As for the configuration mirroring, I'm planning on writing some code to use the command line utilities & Imail APIs to keep both Imail configurations in sync with each other.
