    Hi

    were in the midst of upgrading our clearpass server, it seems the requirement for the disk is Thick Provisioning, is this still compulsary? If anyone  knows the logic behind why the disk type needs to be Thick instead of thin, would appreciate and feedback.

    I can understand it if the underlying storage has limited space but what if the underlying storage has more than enough free space? cant we set the disk type to thin provisioning in that case?

    TIA

    My understand is so it's never oversubscribed.  A Network Access Control system is a critical piece of hardware/software and I wouldn't want to go down because of oversubscribed storage.

    I always thought the requirements are based on what the physical appliances have, hence the high storage and CPUs. The think provisioning is probably due to the appliances having spindle disks instead of SSDs.

    With regards to VMs, I would check with what options the storage has. Many have their own method of deduplication and thin provisioning, letting you create VMs with thick disks.
