Hi

I'm about to install a new TSM 7.1.1 server on RHEL7 and would like to have 
some input on what file system to use, and if I should consider any special 
options.

My first concerns is about the volumes where I intend place the DB and the 
actlog.
We have an IBM x3650 M4 and five 400 GB SSD-drives (SATA-connector) in an 
hw-RAID5 setup to be used by TSM-DB and the actlog.
The OS, arch-log and some space to be used for meta-data from TSM4VE backups is 
located on another hw-RAID5 of five SAS-volumes.

Default file system in RHEL7 is now xfs, and my question is if I should stick 
to what RedHat suggests or if I should go for EXT4 for some reason.
Are there any special concerns to keep in mind for performance (like allocation 
group size and stripe units on xfs) or will "standard" do the work equally good 
?

The blueprint for TSM server on Linux_x86 specifies ext4, but it's for TSM7.1 
and RHEL6.4

Best regards
