RAID Features
Intel
®
RSTe for Microsoft Windows* OS Software User’s Guide 7
2.4.7 Volume Roaming between Linux* and Microsoft Windows*
Intel
®
RSTe supports the ability to move RAID data volumes (configured appropriately) between Linux*
and Microsoft Windows* environments and the RAID data volumes are recognized and available for use.
2.4.8 SGPIO on AHCI Controller
Intel
®
RSTe supports enclosure management, compliant to SFF-8485, to identify drive location or unit
failures on the AHCI controller.
2.4.9 SGPIO on SCU
Intel
®
RSTe supports enclosure management, compliant to SFF-8485, to identify drive location or unit
failures on the SCU.
2.4.10 NCQ (AHCI) and CQ (SCU) Support
Intel
®
RSTe supports Native Command Queuing (SATA AHCI) and Command Queuing (SAS SCU).
2.4.11 SCSI Enclosure Service (SES) v2
Intel
®
RSTe provides support management of enclosures that are compliant with SES (SCSI Enclosure
Services) v2 attached to the SCU controller. Intel
®
RSTe also supports in-band management to SES
compliant expanders attached to the SCU.
Note: SES is not supported under Microsoft Windows* and will be supported in a future release of Intel
®
RSTe.
2.5 Software RAID Functional Support
This section focuses on RAID specific features unless the particular requirement specifies differently.
2.5.1 Matrix RAID
Intel
®
RSTe supports up to two logical RAID volumes on the same array. A RAID array simply refers to
the set of disk drives that can be formed into a RAID volume.
2.5.2 RAID 0/1/5/10 Volumes
Intel
®
RSTe supports base level RAID volumes on both drives connected to the AHCI or SCU controllers.
RAID volume spanning across the AHCI and SCU controllers is not supported. SAS RAID 5 is not
supported on SCU controller.
2.5.3 Simultaneous RAID Arrays
Intel
®
RSTe provides support for RAID volume management on disks attached to the SCU controller
separate from disks attached to the AHCI controller. However, Intel
®
RSTe provides support for
simultaneous RAID management on both.
2.5.4 Disk Coercion
Intel
®
RSTe provides support for Disk Coercion. When a RAID volume is created, this feature will analyze
the physical disks and will automatically adjust (round down) the capacity of the disks to 97% of the
smallest physical disk. This allows for the variances in the physical disk capacities from different vendors.
