Dear Sirs, In a VMware virtualized environment, are there concerns/preferences between putting the database on an RDM disk or Thick Eager Zeroed? Mainly it is going to be one physical server with two guests maximum, one guest with the db and one with the application files, appserver,etc... OS of each guest is on a separate Raid 1 set, with the database(s) on their separate disks and so for the application files. No overcommitting of Ram or CPU resources and no snapshots of the db disks. Since the disks are internal, there may be some checks to be done regarding whether they can be added as Raw disks on VMware, so can we go with Eager Zeroed instead if RDM is a dead end or we try Hyper-V (to see if we can add them as physical disks) Thanks JM
