Data Warehouse and Relational Databases on same VM Machine on different instances

  • I was given a VM Machine and it is to home to a Data Warehouse on one instance and Several Relational Databases on another instance.

    The Relational DB's are used for reporting.

    I need to make a case for RAID configuration for the machine I was provided has three disk with different sizes which is a problem.

    I'm concerned about potential performance and bottleneck issues.

    Any thought would be greatly appreciated.

    In regards to different size drives for a RAID configuration, my understanding is that it can be done but you are limited by the size of the smallest drive.

    Are these three disks allocated to your VM or are they shared by other VMs on the same physical host?
