Assume the following: Let's say I am designing a virt environment via openstack or ovirt. I am perplex on how to approach the implementation in the most cost efficient way. I also need to consider future expansion.
Design 1 (less upfront cost): Have 2 host with good cpu, good ram and good storage. Have the machine connect to a fibre channel switch. Future expansion: just add more machine and make sure it is connected to the switch. For this option I could just simply skip over Fibre channel all together and use iscsi.
Design 2 (more upfront cost): have 2 host, with good ram and good cpu, and one storage node HA (something like dell compellent or netapp). Each host will connect to the storage node via Fibre channel. For future expansion just add more host and connect it to the storage node via fiber channel.
Deisgn 3: /r/linuxadmin recommendation.
I'm leaning towards design 1, it's way less cost and sound simpler. I'm just afraid there might be some issue implementing that way; if so, do enlighten me.
