Mode Operation

The SCSI-to-IDE RAID Controller operates in three (3) modes:

 Self-Diagnostic Mode

 Configuration Mode

 Operation Mode

Self-Diagnostic Mode

To ensure flawless operation, the RAID Controller has a built-in self-diagnostic utility. SelfDiagnostic Mode occurs automatically upon power up, or after the RAID Controller has been reset. During this mode, all components are tested and any potential problems are reported.

The Self-Diagnostic Mode runs three major diagnostic tests. The first diagnostic includes testing the CPU and supporting core logic chips, the internal bus, memory, SCSI controller, and EIDE controllers. The second diagnostic tests for the presence of disks on each individual disk channel. It also checks the functionality of each disk found. The final diagnostic tests the RAID functionality.

Configuration Mode

NOTE: The RAID Controller should be OFFLINE (disconnected from the host system) when

Configuration Mode may be selected whenever the Enter button is pressed during Operation Mode or when the Monitor Utility is invoked from the remote terminal. In Configuration Mode, the user is able to modify the settings of the RAID Controller and perform different functions to the controller.

Entering a Password

If the password-check feature is enabled, the user will be prompted to enter a password before proceeding (the default password is "00000000"). Refer to section "System Params Menu" for information on how to change the default password.

The user may use the front control panel buttons to enter the password. Use the ê and é keys to scroll through the available characters, then use the Enter button to select the character and move to the next position. Once all the characters have been entered, press the Enter button to access the Configuration Mode.

48 Appendix B - Array Basics

Appendix B - Array Basics

The SCSI-IDE RAID Controller allows the set up and management of disk arrays. A disk array is a group of disks that appears to the system as a single virtual disk. This is accomplished through software contained in the RAID controller. RAID (Redundant Array of Independent Disks) refers to disk arrays in which part of the array storage capacity may be used to store redundant information. The redundant information allows the restoration of user data if a disk in the array fails.

The host system views the controller as a single SCSI disk drive. It is actually an array of physical disks behind a RAID controller (it is managed by software to appear as a single physical disk). Depending on the array type, the virtual disk has advantages in fault-tolerance, cost, performance, or a combination of these.

Array Types

Array types are defined by their RAID level, a number from 0 through 5 (a higher RAID level does not necessarily indicate a higher level of performance or fault-tolerance). The RAID Controller allows the user to create the types of arrays proven to be the most useful for RAID applications: RAID 0, 1, 0/1 (also known as mirrored or RAID 10), 3, and 5.

RAID 0 (Striped Disks)

In a RAID 0 array, data is distributed (also known as striped) across the disks in the array. The array appears to the server as one large disk with a capacity approximately equal to the combined capacity of the physical disks. Because multiple reads and writes can be handled in parallel, the input/output performance of the array is much better than that of a single physical disk.

RAID 0 arrays do not store redundant data, so they are not true RAID applications. If one disk fails, the entire array fails and all array data is lost. The fault-tolerance of a RAID 0 is less than that of any single disk in the array. The term RAID 0 is widely used for these arrays however, because they are conceptually similar to true RAID applications.

RAID 1, 0/1, and 10 (Mirrored Disks)

In RAID 1, RAID 0/1, and RAID 10 arrays (commonly referred to as mirrored arrays), disks are paired, with both disks in the pair containing the same data. When data is written to a mirrored array, it is written twice - once to each disk in the pair. A RAID 1 array has only one set of paired disks. A RAID 10 array has multiple pairs, across which data is striped.

The read performance of RAID 1 arrays can be much greater than that of a single disk, while the write performance is slightly lower. In RAID 1/10 arrays, both read performance and write performance are better than those of a single disk.

StorCase Technology, Inc. DS560/DS570 User's Guide - Rev. A04

Appendix B - Array Basics 49

A mirrored array is also highly reliable, because both disks in the pair must fail for the array to fail. For example, an array of five pairs can still maintain integrity even if five disks fail, as long as each pair is left with one good disk. The main disadvantage of a mirrored array is cost. Since all disks must have a twin, twice the number of disks must be used in the array capacity (an eight-disk array contains only four disks of usable capacity).

RAID 3

RAID 3 arrays contain redundant information in the form of parity data, which is calculated block-by-block for all user data. The user data is distributed across all but one of the disks in the array. The parity data is written exclusively to the parity disk (also known as check disk). In the event of a disk failure, the data can be reconstructed from corresponding data stripes on the remaining disk in the array.

RAID 3 provides excellent I/O performance for applications that require high data transfer rates such as image processing, video processing, scientific data collection, batch data processing, or sequential reads and writes.

RAID 5

RAID 5 arrays contain redundant information in the form of parity data, which is calculated block-by-block for all user data. The parity information is distributed across the disks in the array (similar to RAID 0 arrays) and occupies the equivalent capacity of about one disk. Data is interspersed with the parity information. If one disk in the array fails, the data on the failed disk can be reconstructed from the parity data and user data on the remaining disks. Two disks must fail before the entire array fails.

The read performance of a RAID 5 array is excellent, comparable to that of a RAID 0 array. Write performance is lower than that of a RAID 0 array, because write operation involves calculating and writing new parity data as well as writing the new user data.

Mixing Disks from Different Manufacturers or with Different Capacities

An array can contain different models of IDE disks, even disks with different capacities (an array can include a 4GB disk and a 9GB disk). However, if disks with different capacities are mixed, the logical capacity of all other disks in the array is determined by the smallest disk (regardless of RAID level). To maximize disk capacity, use disks of similar size.

Mixing Disks on Different RAID Controller Channels

The RAID Controller Module has two drive channels. An array can consist of disks on different channels of the same RAID controller.
