CONfIgURINg RAID 100 ON TS130

overview

This paper provides an overview of Lenovo ThinkServer RAID 100 on the TS130, and

gives basic instructions for using the pre-boot Configuration Utility to setup RAID storage

configurations on the server. The paper also describes how to manage and monitor the

storage subsystem using the Intel Rapid Storage User Interface application.

rAiD overview

The first step to creating a RAID configuration is to configure the drives into an array,

which is seen by the host computer system as one large disk drive, or virtual drive. The

RAID level will be assigned to the array.

ChooSing the rAiD LeveL

The RAID configuration selected should be based on consideration of several factors, the

most important being performance and fault tolerance.

•

Maximize virtual drive performance by creating a RAID 0 array with striping. Data

is broken into segments and is simultaneously written to or read from several

different stripes on both drives in the array.

•

Maximize fault tolerance to protect against loss of data by creating a RAID 1 drive

group with mirroring. All data is written to the primary drive in the drive group and

is also written (mirrored) to the second drive.

rAiD 0

RAID 0 combines both hard drives so that all data is divided into manageable blocks called

strips. The strips are distributed across the drives in the array. This improves read/write

performance, especially for sequential access, by allowing adjacent data to be accessed

from more than one hard drive simultaneously. However, data stored in a RAID 0 volume

is not redundant. Therefore, if one hard drive fails, all data on the volume is lost.

The RAID 0 volume appears as a single physical hard drive with a capacity equal to

twice the size of the smaller hard drive
