We have a single datacenter, with a single blade chassis, and a single SAN. If something happens to the datacenter, networking, SAN, or blade chassis our entire vSphere environment goes down. Because of that, I really do not care for clustering with multiple VMs. The extra complexity just typically does not make it work it in our environment, but I would love to hear opinions from people that have been working with VMWare extensively. Our SAN does have deduplication across datastores, and trying to decide if VMWare FT would be good in our situation. I guess if you have a blade crash(vmware host) because of hardware, you would not have to wait for HA to try and bring the server up on another host. Would you guys recommend using Vmware FT where possible in our environment? or one something like a fileserver would you just let HA take care of it if that one scenario of a hardware blade failure happens to occur.? If VMWare FT works good and the replication is good enough to set it, and forget it let me know. I really appreciate opinions from people that have been doing a lot of work in Vmware over the years. Thanks,
Dave
