Best File and Print server setup

I'm setting up a new file and print server and was wondering what the best practices are if any to perform this.

I purchased a HP proliant DL380p Gen 8, Intel Xeon E5-2620 v2 @ 2.1GHz, 16GB Ram and 4 900GB 10K SAS.

So what I currently did was the following:

put all 4 drives in

Raid all the drives on raid 5

installed Server 2012 r2 standard (should I use this or should I use 2008 r2???)

I partioned the HDD for 248.37GB and put the OS on that

I then created another partition 1799.28

but I have 466.99GB unallocated and I cannot do anything with it, why am I losing half a TB?

Please let me know what your thoughts are on Best File and Print server, also why the current setup has unallocated space that I cannot use.

Thank you

You have unusable unallocated space because the server is using BIOS and you cannot boot off a GPT (GUID Partition Table) disk with BIOS so the disk is forced to be of type MBR (Master Boot Record).  You cannot fix this without reinstalling.

MBR has a limit of 2 TB.  To get more than 2 TB, you must use GPT.  But in a BIOS based system, the System/Boot drive MUST be MBR.  A second "physical" hard drive can be GPT and the full remainder of that space can then be utilized.

I don't know what HP calls this, but in older Dell models, you would create disk containers - one disk container that is 250 GB (I would likely use 120 GB) for the C: drive, and another disk container with the remaining space.  When Windows is installed, you can then set/convert the set logical disk to GPT and gain access to all the space.

Ok I will try that

as for the other question, should I use server 2012 r2 standard or server 2008 r2 standard for File and Printer server?

Sorry - I don't understand why you would want to use an operating system that's 4 years old and lacks many new features that 2012 R2 has?  Is there a reason you have your doubts about 2012?  Dedupe alone is great - just make sure you understand it, how it works, and the possible issues with backup and restore.
