I'm about the build a Solaris NAS system, currently we have two drives and are planning on adding two more at a later date (2TB enterprise level HDD are a bit expensive!).
Whats the best configuration for setting up these drives bearing in mind I want to expand in the future?
I was thinking of mirroring the drives and then converting to raidz some how?
It will only be a max of 4 drives, the second two of which will be bought later.
Any ideas?
