Hi, im curious if there are some numbers out up to which distance its possible to mirror (raid1) 2 FC-LUNs. We have 2 datacenters with a effective distance of 11km. The fabrics in one datacenter are connected to the fabrics in the other datacenter with 5 dark fibre both about 11km in distance. I want to set up servers wich mirrors their LUNs across the SAN-boxen in both datacenters. On top of this mirrored LUN i put lvm2. So the question is does anybody have some numbers up to which distance this method works ? greetings Stefan Majer - To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
