your server has a sata hard disk connected to the sata0 connector on the motherboard. the windows server operating system has been installed on this disk. the system volume on this disk uses the entire drive. the computer also has two additional sata hard disks installed. one is connected to the sata3 connector, and the other is connected to the sata5 connector on the motherboard. you want to create a virtual disk using a storage pool in this system. because reliability is paramount for this system, you want to use a mirrored layout that allows the virtual disk to be able to survive two simultaneous disk failures in the pool. what should you do? answer nothing. the existing disks can be used for the virtual disk. install an additional hard disk in the system. connect the sata hard disks to consecutive sata connectors on the motherboard. install three additional hard disks in the system. shrink the system volume on the first hard disk and add the resulting space to the pool.
