Disk2 – CoreStorage virtual partition spanned across Disk0 & Disk1ĭell Volume Encryption (DVE) was introduced with Credant Mobile Guardian 6. Disk0s2 – Apple Recovery dynamic Volume. Disk1 (Hard Drive) - GUID Partition Scheme (GPT). Disk0 (Solid State Drive) - GUID Partition Scheme (GPT). Any logical volume managed by CoreStorage becomes a slice of the CoreStorage disk.įigure 4 illustrates an Apple configuration of two physical disks with: Once a virtual partition is created, CoreStorage updates the kernel extensions (KEXTs) to ensure the system loads the virtual partition instead of the managed logical volume. If more than one physical disk is present, CoreStorage will place its most frequently used blocks on the fastest storage device in the pool. 
CoreStorage combines one or more logical volumes across multiple partitions to appear as a single virtual partition.
CoreStorage is a logical volume management (LVM) system layered between the physical disk and logical volumes (LV).
#MAC OS EXTENDED JOURNALED ENCRYPTED OR NOT MAC OS X#
To provide an easier way to manage logical volumes, Apple introduced CoreStorage in Mac OS X Lion (10.7).
