Internal and External HDT Pools

Any thoughts on creating HDT Pools that span both internal and external subsystems? Currently considering doing so with VSP and HUS products.

SSD, SAS 300,600 10K internal and 2TB SAS external, we will be doing so via the fabric, not direct attached.

I can see advantages to doing so from a fully automated tiering pespective, however is it worth the risk? the flip side is to create 2 distinct HDT pools one internal SSD and 300 SAS and one external 600 SAS and 2TB, and use HTSM to do manual LDEV migrations to a lower tier.

Has anyone spanned an HDT pool, if so any issues, advice?
