1) Create 1 large logical drive & then create the remaining 3 partitions in OS?
2) Create 4 logical drives?
Thanks for you feedback!

Re: RAID scenario question
I hope you are fully aware of the fact that if we are creating a logical drive in an RAID ARRAY than in OS it would be detected as a single hard drive.
In case of Hardware RAID we uses the Array configuration utility to create a RAID Array then we create a logical drive to group the harddrives. Each logical drive is seperate harddrive for the OS.
If there is any confusion then
Let me clarify the scenerio :
1)Create 1 large logical drive & then create the remaining 3 partitions in OS?
: OS would detect 1 large hard drive then we can create OS level partitions as per our requirement.
2) Create 4 logical drives?
: OS would detect 4 small hard drives then we can use them as per our requirement.

SolutionI would create 4 logical drives in the ACU.
If you do, you can extend any of the partitions when needed. I you choose to create 1 logical drive and then create partitions from the OS, you can only extend the last partition.
I'll try to visualize it.
4 logical in ACU
1 -------
2 -------
3 -------
4 -------
You can extend all four logical units independent of each other.
1 logical
1------2-------3------4----
You can only extend partition 4
Hope I didnt confuse u...

Re: RAID scenario question
You have the best performance if your RAID and partitions or logical drives are from hardware (Smart array) and not from software (OS). It reduces the CPU utilization.
You can take all advantages from Smart array controllers.
Procedure on ACU:
Create a new RAID 5
Divide the space available in 4 logical drives.
Format all 4 logical drives on OS
Done
