RSTe for Microsoft Windows* OS Software User’s Guide
 Indication profile
Intel
®
RSTe supports an industry standard management API based on CIM model and Storage Management
Initiative Specification (SMIS) specification (Linux*).
This feature is supported on platforms that have installed Linux*, Microsoft Windows 7*, and Microsoft
Windows 2008* GA and R2.
2.3.2 Common Storage Management Interface (CSMI)
Intel
®
RSTe supports the Common Storage Management Interface (CSMI) for reporting RAID
configurations and SMP, SSP, STP pass through.

RSTe System Configurations Supported
This section addresses to physical components of the system configuration supported by Intel
®
RSTe.
2.4.1 SCU and AHCI Controller Support
 Intel
®
RSTe provides support for managing RAID volumes on drives attached to the AHCI ports.
 Intel
®
RSTe provides support for managing RAID volumes on drives attached to the SCU ports.
2.4.2 SAS Expander Support
Intel
®
RSTe supports expanders attached to the SCU controller (provide external HW drive and expander
compatibility list). Intel
®
RSTe does not support the use of port multipliers on either the AHCI or SCU
controller.
2.4.3 Pass-through Drives
Intel
®
RSTe supports the ability to expose non-RAID configured disks (pass-through) to Host OS.
2.4.4 SCU Controller RAID Management Limitations
Intel
®
RSTe supports the RAID management of up to 32 physical drives attached to the SCU controller.
Drives added beyond this limitation (up to a total of 128 drives) are supported as pass-through drives but
are not validated as part of supported RAID array configurations. The Intel
®
RSTe GUI allows up to 8
RAID volumes to be created across the 32 drives. For example, a RAID array that encompasses all 32
drives results RAID volume limitation of up to 2 volumes (Matrix RAID allows 2 RAID volumes per
RAID array).
No OS based software RAID (non-Intel
®
RSTe) limitations are imposed.
2.4.5 Hot Plug
Intel
®
RSTe supports the ability Hot Plug (remove and replace) disk drives on the AHCI controller whether
or not I/O is being processed, provided that the capabilities are enabled in the BIOS.
Intel
®
RSTe supports the ability to Hot Plug (remove and replace) disk drives attached to the SCU
controller whether or not I/O is being processed.
Note: The Hot Plug is not supported under Linux* currently. Fix will be in future release.
2.4.6 SCU and AHCI drive roaming
Intel
®
RSTe supports the ability to move RAID volumes on SATA drives between the AHCI and SCU
controllers and have RAID arrays and volumes recognized, available and bootable from the common
metadata.
