Everyone, I have this setup (please check attached picture). WAN link has dedicated 2048 Kbps (with average 14 miliseconds between nodes ) LB 1, 2, 3 Servers are Load Balancers Node 1, 2, 3, 4 are Redhat Enterprise linux ES v4 + GFS MSA1000 storage has 30 Gig of Data right now, and can grow beyond 100Gigs. Can someone help me out to figure the best GFS configuration to have: 1- Mirrored storage over the Wan Link ? 2- What options can be setup for asynchroneous replication of the storrage if the WAN link is becomes too thin for synchronous replication ? 3- Nodes 3 & 4 fail over Nodes 1 & 2, supposing that Node 1 and 2 are unavailable ? 4- Does GFS over DRBD work at this time ? and have someone implement it ? Thanks for your help, Dan __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo!
