Does this seem like a good setup for a dedicated Search head, indexer for a virtualized Splunk?

Search Head
- 8 core 16 GB Ram

Indexer
- 8 core 8 GB Ram 1 TB Hard Drive

We will have approximately 3 concurrent users at a given time, and a throughput of 10 GB/day

Bear in mind that indexing performance is about 30% slower on a virtual machine. Search performance is about equivalent to physical hardware.

I have modified my post, does that look much better?

I'd swap the cores around, giving the search head more oomph.
