Data Protection

•  Unmatched protection against drive failures

•  Shorter rebuild times reduce exposure to

multiple cascading disk failures

•  DDP’s dynamic rebuild process uses all the

drives in a disk pool for the reconstruction of

the failed drive

•  Critical data within a DDP stripe is given

reconstruction priority to protect against data

loss should a multiple drive failure occur

•  Provides significant improvement in data

protection

•  Larger pool provides even greater protection
