No matter what you implement there are bound to be issues... Here is the list I have as a set base of consideration:
1. Synchronization can take time ... Solution: have synchronization run at file / OS level to distribute new items... Problem: lots of simultaneous access could make the site perform poorly or even crash... 2. Multiple synchronizers can cause things to be out of sequence.. Solution: centralize synchronization - parent to children relationship.. Problem: Single point of failure on the parent - implement 2 parents... 3. Backup and security... Both have unique needs and windows of time... Solution: Create N+1 spare duplicate to keep a snapshot of all data for backup and security considertations offline... Those are my major items... Best thing to do: 1. Implement NAS 2. Implement duplicates of NAS via Samba on various Unix varieties 3. Run commercial or CLI unix type sychronizers... 4. Parse data out of CF and have mechanism to do a bulk update... setup a scheduled event to parse out all new pages on some schedule to 'refresh' / validate everything... Still some mechanism for making the parent - the NAS - redundant are needed.. That could be done by putting a spare NIC in each NAS type box and exchanging data, or a P2P small server/client app (best idea).. -paris Paris Lundis Founder Areaindex, L.L.C. http://www.areaindex.com http://www.pubcrawler.com 412-292-3135 [finding the future in the past, passing the future in the present] [connecting people, places and things] -----Original Message----- From: "Ben Koshy" <[EMAIL PROTECTED]> Date: Mon, 27 Jan 2003 01:25:26 -0800 Subject: RE: Load Balancing: Disk Options? > That solution doesn't sound very clean, especially if one mapped > drive > is down and we have to trap & catch errors when one disk is down. > Then > after the drives get out of sync, some sort of sychronization would > have > to be initiated, plus we would have to determine which drive is out > of > sync.
