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.
