Virtualising Servers and Shared Storage
Hi all, I'm currently putting together a new network using 2 VMware hosts with shared storage. Our budget wont stretch to a SAN but if we were to use something like a Synology RS2212+ (or even a bigger model with 4 GBe ports) would that work for storing 4 or 5 virtual machines (probably more in the future) plus all the users data etc? We have around 25 desktop machines but need quite a lot of storage capacity. The other alternative is to put a RAID 1 set in each of the hosts for the VM's and have all the user data stored on the NAS via iSCSI.
I assume that having the OS storage locally on the hosts gives better performance but is more difficult to backup and more difficult to migrate should there be a fault with one of the hosts. (We will be using the free version of ESXi so wont have vMotion)
Having everything stored on the NAS makes it easier to backup as all the data is in one place, but you end up with a single point of failure.
Some advice would be very much appreciated! :)
