With an E2860 (60-drive array), you have enough drives for multiple dynamic disk pools and volume groups. With an E2812 (12-drive array), you only have enough drives for one DDP and a single drive RAID0 volume group (1 drive with no parity). How do Volume Groups differ from Dynamic Disk Pools in E-Series storage?
