controller can have one or two global hot spare disks available to automatically replace a failed disk in the IM or IME storage volumes on the controller. Hot spares make the IM/IME volume even more fault- tolerant. Note: You can also configure one IM or IME volume and one Integrated Striping (IS) volume on the same LSI SAS controller. -
Page 19: Im/Ime Description
Fusion-MPT architecture. Easy-to-use BIOS-based configuration utility. Error notification: the drivers update an OS-specific event log. SES status LED support. Write journaling, which allows automatic synchronization of potentially inconsistent data after unexpected power-down situations. Metadata used to store volume configuration on mirrored disks. Automatic background resynchronization while host I/Os continue. -

Figure 2.1 Typical Integrated Mirroring Implementation IM Volume Primary Mirror NVSRAM (For Write Journaling) Memory Fusion-MPT Controller FLASH (For Configuration) The advantage of an IM/IME volume is that there is always a second, mirrored copy of the data. The disadvantage is that writes take longer because data must be written twice. -

order to verify the configuration. The usable disk space for each member disk is adjusted down when the configuration is created, in order to leave room for this data. 2.4.3 Hot Swapping The firmware supports hot swapping. The hot-swapped disk is automatically resynchronized in the background, without any host or user intervention. -
Page 23: Media Verification
2.4.6 Media Verification The firmware supports a background media verification feature that runs at regular intervals when the IM/IME volume is in optimal state. If the verification command fails for any reason, the other disk’s data for this segment is read and written to the failing disk in an attempt to refresh the data. - Page 24 Overview of Integrated Mirroring and Integrated Mirroring Enhanced Version 1.1 Copyright © 2006, 2007 by LSI Logic Corporation.
