If I am booting a VSphere Host server from local disks but ALL of the VMFS volumes are on the SAN, does it really matter that much what I use for the local disks (SAS vs SATA?).  NONE of the guests will run from the local disks, it’s only the base VSphere load that resides there.

Most of my current servers are Dell and have 2 SATA disks in a RAID 1 (SAS6i controller) but I would like to know if there is any local swapping/logging that might be noticeably improved  if I used two 15k SAS drives instead ?
