2.2 IM Features
LSI Logic Integrated Mirroring and Integrated Mirroring Enhanced support the follow-
ing features:
Configurations of one or two IM or IME volumes on the same LSI Logic SAS
controller. Each volume can consist of two mirrored disks (IM) or three to eight
mirrored disks (IME).
(Optional) One global hot spare disk per controller. If a global hot spare disk is
defined, the upper limit for an IME volume is seven mirrored disks.
Mirrored volumes run in optimal mode or in degraded mode (if one mirrored disk
fails)

Supports both SAS and SATA disks, although the two types of disks cannot be
combined on the same LSI Logic SAS controller
