Block Virtualization Process

Block Virtualization Process

Block virtualization technology enables dynamic allocation and expansion of storage resources in storage pools. Using this technology shortens the response time for data reads/writes in the storage pools and the time needed to reconstruct data on failed disks.

Figure 1-1 Block virtualization process
  1. The storage system divides the storage media in a disk domain into fixed-size CKs.
  2. CKs in each storage tier are grouped into CKGs and hot spare space based on the RAID policy and hot spare policy specified on DeviceManager.
  3. The storage system divides CKGs into extents.
  4. The storage system divides extents into grains based on the file system block size configured on DeviceManager. The file systems used by application servers are composed of grains.
