Configuring RAID for machine types 4262, 4263, 4264, and 4265
This section contains information about the required number of SATA hard disk drives for the supported level
of RAID and SATA RAID configuration for machine types 4262, 4263, 4264, and 4265.
Installing SATA hard disk drives
Your computer must have the minimum number of SATA hard disk drives installed for the supported level of
RAID below:
•
RAID Level 0 – Striped disk array
–
Two hard disk drives minimum
–
Better performance without fault tolerance
•
RAID Level 1 – Mirrored disk array
–
Two hard disk drives minimum
–
Improved read performance and 100% redundancy
•
RAID Level 5 – Block-level striped disk array with distributed parity
–
Three hard disk drives minimum
–
Data striped at the byte level
–
Stripe error correction information
–
Better performance and fault tolerance
To install a new SATA hard disk drive, see “Installing a new hard disk drive” on page 23.
