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 sizes: 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 hard disk drives
– Supported strip sizes: 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 at least two hard disk drives
– Improved read performance and 100% redundancy
• RAID Level 5 - Block-level striped disk array with distributed parity
– A RAID Level 5 hard disk drive group consisting of at least three hard disk drives
– Supported strip sizes: 8 KB to 1 MB
– Better performance and fault tolerance
– RAID Level 5 is supported by some models of LSI MegaRAID adapter cards
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.
