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

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.

Coin-cell battery

Prerequisite

Before you start, read Generic Safety and Compliance Notices, and print the following instructions.

Your computer has a special type of memory that maintains the date, time, and settings for built-in features,

such as parallel connector assignments (configurations). A coin-cell battery keeps this information active

when you turn off the computer.

The coin-cell battery normally requires no charging or maintenance throughout its life; however, no coin-cell

battery lasts forever. If the coin-cell battery fails, the date and time information is lost. An error message is

displayed when you turn on the computer.

To dispose of the coin-cell battery, refer to the “Lithium coin-cell battery notice” in the Safety and Warranty

Guide.

For access, remove these parts in order, if any:

• “Computer cover” on page 32

• “Optical drive” on page 33

Appendix A. System memory speed

The Intel Xeon® or Intel Core™ microprocessor families compatible with this ThinkStation computer feature

an integrated memory controller. The memory controller provides the microprocessor with direct access to

the system memory. Therefore, the system memory speed will be determined by the memory module type,

frequency, size (capacity), the number of memory modules installed, and the microprocessor model.

Notes:

• The actual system memory speed of the memory modules varies depending on the microprocessor model

or memory type/configuration. For example, if your computer comes with three or four dual Rank 3200

MT/s memory modules, then the system memory speed may be no faster than 2933 MT/s.

• Processor DDR4 2DPC is supported when channel is populated with the same DIMM part number.

Symmetric configurations are required for 2DPC within one channel. Vendor mixing within a channel is not

allowed.

• The microprocessor models supported in your computer might vary. For a list of supported

microprocessor models, contact the Lenovo Customer Support Center.

• The ECC memory modules are not supported on the computer models with Intel Core i3, i5, i7 or i9

microprocessors.

Refer to the following information about the system memory speed:

• Memory module types:

– DDR4 ECC UDIMMs

– DDR4 non-ECC UDIMMs

• Memory module operating voltage: 1.2 V

• Memory module frequency: 3200 MHz
