The goal in meeting the hardware requirements is to have a
shared storage for the two nodes. The way to achieve this in
VMware is the creation of a NEW SCSI BUS. It has to be of
type "virtual" and we must have the disk.locking = "false"
option.
Just dataCacheMaxSize = "0" should be sufficient with the
diskLib.* parameters, although I include all parameters for
documentation purposes.
maxUnsyncedWrites should matter for sparse disks only, and
I certainly do not recommend using sparse disks for
clustering.
dataCacheMaxSize=0 should disable cache size completely, so
other three dataCache options should do nothing (no harm,
but nothing good either).
