Installing SATA or SAS hard disk drives
Ensure that your computer has the minimum number of SATA or SAS hard disk drives installed for the following supported levels of RAID:
•RAID Level 0 - Striped disk array
–A RAID Level 0 hard disk drive group consisting of at least one hard disk drive
–Supported strip size: 8 KB to 1 MB
–Better performance without fault tolerance
•RAID Level 00 - Spanned hard disk drive group with a series of RAID 0 hard disk drive groups
–A RAID Level 00 hard disk drive group consisting of two or four hard disk drives
–Supported strip size: 8 KB to 1 MB
–Better performance without fault tolerance
•RAID Level 1 - Mirrored disk array
–A RAID Level 1 hard disk drive group consisting of two or four hard disk drives
–Improved read performance and 100% redundancy
•RAID Level 10 - A combination of RAID Level 0 and RAID Level 1
–A RAID Level 10 hard disk drive group consisting of four hard disk drives
–Data being striped across hard disk drive groups
–Provides both high data transfer rates and complete data redundancy
•RAID Level 5 -
–A RAID Level 5 hard disk drive group consisting of at least three hard disk drives
–Supported strip size: 8 KB to 1 MB
–Better performance and fault tolerance
–RAID Level 5 might not be available on all models of LSI MegaRAID adapter
•RAID Level 6 -
–A RAID Level 6 hard disk drive group consisting of at least four hard disk drives
–Supported strip size: 8 KB to 1 MB
–Better performance and fault tolerance that can stand up to loss of two hard disk drives
–RAID Level 6 might not be available on all models of LSI MegaRAID adapter
Ensure that the LSI MegaRAID SAS adapter card is installed in your computer, and that the hard disk drives are connected to this adapter card and not to the connectors on the system board.
