Hello,
Still in deployment planning, I am wondering how much hosts should I put in a single cluster ? I am using Cloudstack 3.0.2 with KVM on CentOS 6.2 hosts. What are the advantages and drawbacks of putting hosts in the same cluster ? >From what I see, if I am in the same cluster, I can migrate instances between >hosts, what I can not do between different clusters, I can also migrate >primary storage. What happens if I had more than 16 hosts in a KVM cluster (16 seems to be the limit from the advanced install guide). I am using iSCSI luns as primary storage and Dell C6220 servers (4 servers in 2U chassis, sharing power input). I thought first I would divide each chassis in its own cluster, but, from management side, I need to create a new lun for every chassis. If I need to do some operations on a chassis, I need to put all servers in the cluster in maintenance mode, but it seems I can't do that ! At least one server should be up, no ? Any advice would be greatly appreciated ------ Attention, changement d'adresse et de numéro de téléphone !
