Create global Disk Group Policy with different drive sizes?

We currently use the following disk sizes in our environment for rack servers:

  1. 300GB HDD/SSD as a 2-disk RAID1 for OS.
  2. 960GB SSD as a 5-disk RAID5 for Data.
  3. 240GB SSD as a 5-disk RAID5 for Data.

At the moment, our UCS service profile templates are only configured for RAID1 using the "profile-STR-diskprofile" profile and RAID5 using the same profile "profile-STR-diskprofile".

The storage profile Local Luns profile is setup in this way:

  • RAID1: Size (GB) = 1, Auto-Deploy, Expand To Available checked, Disk Group Configuration = STR-OS
  • RAID5: Size (GB) = 1, Auto-Deploy, Expand To Available checked, Disk Group Configuration = STR-Data

Disk Storage Groups are setup in this way:

  • STR-OS: RAID Level = RAID 1 Mirrored, Disk Group Configuration (Automatic) selected, Number of drives = 2, Drive Type = HDD, Use Remaining Disks unchecked, Use JBOD Disks = No.
  • STR-Data: RAID Level = RAID 5 Striped Parity, Disk Group Configuration (Automatic) selected, Number of drives = 4, Drive Type = SSD, Use Remaining Disks unchecked, Use JBOD Disks = No.

I would like to setup a new storage profile such that it creates the following:

  • RAID1 using 2 disks (HDD or SSD) for the smallest drives.
  • RAID5 using 5 disks (HDD or SSD) for the rest of the drives. If there are 10 drives available, then create 2x RAID5 LUNs. If there are 15 drives available, then create 3x RAID5 LUNs. But only use same size drives within each RAID group.

Is this possible?

I don't know if I was clear in my above question, but I just want all UCS rack servers to be configured with:

* RAID1 using 2 of the 300GB disks for boot.

* RAID5 for everything else, using 5 disks in each RAID group.
