I have Enterprise Vault 9 setup for an Exchange 2010 DAG on VM's (Exchange and EV) and all is working well. I was wondering what the best practices/recommendations of how to use partitions are when using tiered SAN storage. My understanding is that they are mainly for providing additional capacity at different locations, however in the event of running out of space more disks would be added to the SAN, so are there any issues with having one large open partition?
I have setup a dedicated RDM mapping for the drives hosting the data so these can be extended easily (unless anyone knows of issues with extending the storage for EV) so is there any considerations I am missing maybe in terms of backup, performance that I should be using partitions for? Would I benefit from creating partitions so that this data is dynamically moved to the lower tiered storage? I'm a little confused as to what access is available once a partition is closed from the perspective of users, does this affect the way they can search etc or is it literally a logical storage divider?
Thanks in advance for your comments!
