Mirror (RAID 10) for High
Performance and High Security
RAID subsystem could be configured to support Stripe
and Mirror at the same time, i.e. RAID 10. Take four
hard drives in RAID 10 as an example. Hard drive 0
and hard drive 1 could act as Mirror 1. Hard drive 2
and hard drive 3 act as Mirror 1 too. The RAID
controller then configures these two Mirrors as Stripe.
At least two drives (either one in each Mirror) can be
allowed to fail without any impact to RAID data
access. If two drives from the same Mirror are failed,
the RAID data is not accessible and becomes invalid.
CLONE
Clone
’
s action is similar to RAID 1. However, all of the
hard disks will be the mirrors. For example, in a four
hard drives Clone environment, data in each hard
drive will be the same. This mode is useful especially
when users would like to copy data from a hard drive
to several hard drives at the same time.
The number of allowed failed drives is the
total number of drives in the RAID minus
one.
Concatenating (Large)
This mode is also named
“
Large
”
. In this mode, the RAID controller
will concatenate all of the hard drives into a single hard drive with
larger capacity. For example, if three 500GB hard disks are
connected to the RAID subsystem in Large Mode, user will get a
single hard disk with capacity of 1,500GB.
If any one hard disk gets defective, information
stored in this LARGE RAID will become invalid.
