Virtual Disk vs Redirected Device

We aren't doing any HA, we just want FAST storage, is there an advantage to using a vdisk over a redirected device?

1) Single node device with our concept and architecture is slower then HA. For a simple reason: with MPIO read and write requests are served by multiple nodes @ the same time. So performance increases with the scale-out.

2) We'll represent single + async replication with V8.

Fair enough, but we won't be using HA.

So what are the best settings to get the best performance out of a single node?

Well, it pretty simple then - give it as much RAM as possible to run cache, put SW VDs on the fast disks or RAID, and make sure that network part will not be the bottleneck. That should do the work.
