thanks Alex, So if we have a standalone whitebox that we want to use as an iscsi backup target,are our options;
1: We continue to use a ZFS based box running somehthing like OmniOS with disks passed through as RDM or using PCI controller pass through like we do at the moment?
2. We create 3 VMs and then present the storage back to the host
3. We run nested vsphere instances - which isn't viable due to the nesting overhead and also VMware licensing.
If we went for option 2 - would that provide better performance than 1.
So for our Tier2 backup storage it looks like we are going to get much better bang for the buck by keeping using our ZFS based vSANs?
Its a shame the ScaleIO product can't be deployed onto a single host and single OS instance - it would open up the market for the product.

Hi Ashley,
ScaleIO is an enterprise level storage, which means redundancy, thus single component failure should not affect the clients.
ScaleIO was designed to run on physical hosts, therefore, using option 2 or 3 will work, however you won't get the desired performance.

ScaleIO needs minimum of 3 nodes for installation.
The single mode option might be misleading, but it refers to MDM cluster, and not the number of SDS nodes.
