I've never configured internal storage on a UCS blade. We have a pair of B200-M5s that will get Win2016 Server loaded. I want to RAID1 the two internal physical drives, but present the O/S with a 100GB boot LUN and a second LUN for whatever else. I'm lost in the configuration - Disk Group Policies, Local LUNs, Storage Profiles, Storage Policies, Controller Definitions, .....
I'm used to just setting up a pair of SD cards for VMware install. Storage Noob needs help!
Thanks

I thought I should come back and state the solution. In the SCSI controller board BIOS available during POST, you can get in and configure the mirror set of drives, then on that mirror set you can create logical disks. We took the 600GB mirror and made it 100/500 logical drives. This showed up in the local Windows Server 2016 install as a 100GB drive and a 500GB drive, which is what the Windows admin was expecting. Thanks.

Are you using M.2 storage controller/disks? If so, you need to use "Embedded Local Disk" in the boot policy. This sometimes also requires creating a Storage profile to map this LUN.
If you can provide some additional details on your setup, maybe we can provide some guidance.

Thanks for that info.
If Windows is able to see the 600GB LUN, you are half way there. During install, you can use Windows to partition the drives into your 100GB boot and 500GB data partitions and then your Windows team will see two partitions of the RAID 1 disk.
Similar to this procedure: https://www.youtube.com/watch?v=_8UN1njjDkM
Good Luck

He is used to VMs, not physical servers. In VMs, we give 100GB virtual disk for C: and then other virtual disks for whatever else is required. Can we provide what he is expecting to see with this hardware? Thanks.

Hi,
Well there's a lot of things you have todo for your scenario!
First of all, for your Boot-from-SAN LUN, which protocol are you using? iSCSI or Fibre Channel?, depending on this you will need to define the addressing pools (MAC Pools, IP Pools and IQN Pools in case of iSCSI, WWNN and WWPN in case of FC). Then you will need to configure the necessary iSCSI vNICs or vHBAs for the service profile of that server.
After this you need to define a Boot policy in which you will add the target IP/IQNs or WWNs for the storage (see BootP image). Also, you can check out this video (even though it's from like 5 years) but it's essentially the same just the GUI is different.

For the physical drives you need to configure a Local Disk Policy using RAID 1 mirrored.
