Chapter 6. RAID

What is RAID

Redundant Array of Independent Disks (RAID) is a technology that provides increased storage functions and reliability through redundancy. It also can improve data storage reliability and fault tolerance compared with single-drive storage systems. Data loss resulting from a drive failure can be prevented by reconstructing missing data from the remaining drives.
When a group of independent physical storage drives is set up to use RAID technology, they are in a RAID array. This array distributes data across multiple storage drives, but the array appears to the host computer as one single storage unit. Creating and using RAID arrays provides high performance, such as the expedited I/O performance, because several drives can be accessed simultaneously.

RAID Level

Your computer must have the minimum number of SATA storage drives installed for the supported level of RAID below:
• RAID 0: striped disk array
– Consists of at least two SATA storage drives – Supported strip size: 4 KB, 8 KB, 16 KB, 32 KB, 64 KB, or 128 KB – Better performance without fault tolerance
• RAID 1: mirrored disk array
– Consists of two SATA storage drives – Improved reading performance and 100% redundancy
• RAID 5: block-level striped disk array with distributed parity
– Consists of at least three SATA storage drives – Supported strip size: 16 KB, 32 KB, 64 KB, or 128 KB – Better performance and fault tolerance
• RAID 10: striped and mirrored disk array
– Consists of at least four SATA storage drives – Supported strip size: 4 KB, 8 KB, 16 KB, 32 KB, or 64 KB – Better performance without fault tolerance – Improved reading performance and 100% redundancy

Configure the system BIOS to enable SATA RAID functionality

To enable SATA RAID functionality:
1. Restart the computer. When the logo screen is displayed, press F1 or Fn+F1.
2. Select Devices ➙ ATA Drive Setup and press Enter.
3. Select Configure SATA as and press Enter.

What are CRUs

Customer Replaceable Units (CRUs) are parts that can be upgraded or replaced by the customer. Lenovo computers contain the following types of CRUs:
• Self-service CRUs: Refer to parts that can be installed or replaced easily by customer themselves or by trained service technicians at an additional cost.
• Optional-service CRUs: Refer to parts that can be installed or replaced by customers with a greater skill level. Trained service technicians can also provide service to install or replace the parts under the type of warranty designated for the customer’s machine.
If you intend on installing the CRU, Lenovo will ship the CRU to you. CRU information and replacement instructions are shipped with your product and are available from Lenovo at any time upon request. You might be required to return the defective part that is replaced by the CRU. When return is required: (1) return instructions, a prepaid shipping label, and a container will be included with the replacement CRU; and (2) you might be charged for the replacement CRU if Lenovo does not receive the defective CRU within thirty (30) days of your receipt of the replacement CRU.
