Hi everyone, I'm new to CloudStack and am trying to understand how it works with regards to storage exposed to hypervisors.
For example: My company, SolidFire, has a feature that exists at the virtual-volume (for us, equivalent to a LUN) layer: Hard Quality of Service. So, for each volume in one of our clusters, you can specify a minimum and maximum number of IOPS (beneficial to Cloud Service Providers who want to write hard SLAs around performance). We have a potential customer who is using CloudStack currently with another vendor (via NFS shares). They asked me today how a hypervisor run under CloudStack would see the iSCSI storage exposed to them in one of our volumes. More specifically, can the hypervisor see a volume per VM or is the hypervisor forced to create all of its VMs off of the same volume? If the hypervisor is forced to create all of its VMs off of the same volume, then this would significantly reduce the value of our hard quality of service offering since all of these VMs would have to run at the same performance SLA. Can anyone help me better understand how this would work?
