1.4.3 Easy of Use features
1.4.3.1 Instant Availability/Background Initialization
RAID 0 and RAID 1 Volume Sets can be used immediately after the creation.
But the RAID 3 and 5 Volume Sets must be initialized to generate the parity.
In the Normal Initialization, the initialization proceeds as a background task,
the Volume Set is fully accessible for system reads and writes. The operating
system can instantly access to the newly created arrays without requiring a
reboot and waiting the initialization complete. Furthermore, the RAID Volume
Set is also protected against a single disk failure while initialing. In Fast Initial-
ization, the initialization proceeds must be completed before the Volume Set
ready for system accesses.
1.4.3.2 Array Roaming
The SurfRAID TRITON Mini stores configuration information both in NVRAM
and on the disk drives It can protect the configuration settings in the case of
a disk drive or controller failure. Array roaming allows the administrators the
ability to move a complete RAID Set to another system without losing RAID
configuration and data on that RAID Set. If a server fails to work, the RAID
Set disk drives can be moved to another server and inserted in any order.
