RAID EzAssist User’s Manual
Level 10
Combines RAID 0 striping and RAID 1 mirroring spanned across multiple
drive groups (super drive group). This level provides redundancy through
mirroring.
Level 30
Data is “striped” across multiple drive groups (super drive group).
Maintains parity information which can be used for data recovery.
Level 50
Data is “striped” across multiple drive groups (super drive group). For data
redundancy, drives are encoded with rotated XOR redundancy.

Note
The host operating system drivers and software
utilities remain unchanged regardless of the level of
RAID installed. The controller makes the physical

RAID (Level) Migration
A features in RAID subsystems that allows for changing a RAID level to
another level without powering down the system. It is a feature supported in
the newer Mylex RAID products.
RAM
Random Access Memory, the "built-in" readable and writable data storage
that comes with (or can be added to) a computer.
Read Ahead Cache
The process of reading a data sequence ahead of the actual requested data
and placing the data in cache. For sequential data access applications, this
approach results in improved read performance. For random access
situations, however, read ahead caching may result in slower performance.
