4.2 RAID 1 (Mirror) for High Security
Mirror or RAID 1 is the replication of data onto separate hard disks in real time to ensure continuous
availability. Take a RAID 1 system with two hard disks as an example, data in a hard disk will be exactly
the same as the data in another hard disk.
(Failure in a hard disk, Host controller still could read/write data. Users have to replace the defect hard disk.
T5 will enter on-line-auto-rebuild mode automatically)
4.3 Stripe + Mirror (RAID 10) for High Performance and High Security
T5 could be configured to support Stripe and Mirror at the same time, i.e. RAID 10. Take four hard drives
RAID 10 as an example. Hard drive 0 and hard drive 1 could act as Mirror 1. Hard drive 2 and hard drive 3
could act as Mirror 1 too. 2350ESR then configure these two Mirrors as Stripe.
