Hello, this is my first server setup and I have a new HPE Proliant ML350 GEN10 Server with 4 each 600GB Drives and an HPE Smart Array P408i-a SR Gen10 controller. My plan is to set up a RAID 5 array using three of the drives while making the fourth drive a Hot Spare. While setting up the RAID 5, I did not see a way to create the C and D partitions. (C for the OS and D for the database.)
After creating the RAID 5 array and installing Windows Server 2016, I booted the OS and resized the drive and created a D partition using Disk Manager in Windows.
Is there a downfall using this configuration? Should I have purchased more drives and set up the OS separately using RAID 1 and the Data using RAID 5?
