Aside from the obvious performance considerations, would there be any software or design limitations building a PetaSAN using the same mentality?
I'll elaborate a little for those not familiar with HP's StoreVirtual VSA product. You have a two node cluster with a tie-breaker (three VMware hosts total). Two of the VMware hosts have large, direct attached storage. Nearly all of the storage on these VMware hosts are assigned to a pair of HP Appliances, one residing on each host. These HP Appliances replicate data between themselves and represents the storage via iSCSI to the hosts that they reside on. There is a third HP Appliance that runs on the third VMware host to act as a management agent and tie-breaker.
Maybe you've implied that PetaSAN can work in this type of environment, but I thought I would come right out and ask. 🙂

However i am aware of several implementations of virtualizing a traditional 2 node SAN with mirrored disks to build a hyper-converged setup on pairs of hypervisors. PetaSAN is different than 2 node SANs in being scale out, can it in the future be configured in a hyper-converged setup ? probably but currently it is not in our immediate list.
