The PCI Express interface is compliant with the PCI Express Specification, revision
1.0a. All PCI software is backward compliant with previous versions of the PCI
Express specifications. The PCIe to SAS HBA interface is compatible with the ANSI
Serial Attached SCSI Specification, revision 1.0 and the Serial ATA Specification,
revision 1.0a.
Performance
The SG-XPCIE8SAS-I-Z HBA is based on LSI’s 1068E chip.
The HBA can create hardware RAID volumes of types RAID 0, 1, or 1E. There are
various ways you can create these volumes:
For the Solaris, Linux, and Windows OS, you can use an LSI BIOS configuration
utility to set up RAID volumes, except for servers with a SPARC processor. See
Mirroring Your Boot Disk, later in this chapter.
For already-installed Linux and Windows OS, you can use the MSM (MegaRAID
Storage Manager) program to set up and manage RAID volumes.
For the Solaris OS, you can use the Solaris raidctl command to set up and
manage RAID volumes, for all processors including SPARC processors.
The SG-XPCIE8SAS-I-Z HBA can create two and only two volumes. The two
volumes can contain up to 12 disks total plus zero, one, or two hot spares (no more
than 14 disks).
RAID 0 can have two to 10 striped disks.
RAID 1 can have two mirrored disks plus zero, one, or two hot spares. Only two
disks are permitted in a RAID 1 mirror.
RAID 1E can have up to 12 mirrored disks plus zero, one, or two hot spares, if all
disks are in one volume and there is no other volume. RAID 1E requires a minimum
of three disks.
You can simultaneously have one volume of RAID 0 and another of either RAID 1 or
1E.
Note The Sun LSI 106x RAID User’s Guide (document number 820-4933) describes
the different types of RAID volumes in detail. This guide can be found in the
collection of documents for your server at http://docs.sun.com.
The SG-XPCIE8SAS-I-Z can simultaneously address RAID volumes and individual
disks that are not in RAID volumes.
