Hold <Ctrl> while selecting ready drives on the Physical Drives window, then click on Accept Array to add the drives to the arrays shown in the Arrays window. If you need to undo the changes, press the Reclaim button. 1-14 WebBIOS Configuration Utility Version 1.0 Copyright © 2003 by LSI Logic Corporation. All rights reserved. Step 5. After you create the arrays, click on Next. The Logical Drive Definition screen displays. You can use this screen to select the RAID level, stripe size, read policy, cache policy, spanning option, and logical drive size. Step 6. Set the following options to define the logical drive: a. Select the RAID level. b. The possible RAID levels for the logical drive display in the dropdown menu. Select the stripe size. Figure 1.8 WebBIOS Logical Drive Definition Screen The stripe size parameter specifies the size of the segment written to each disk in a RAID configuration. You can set the stripe size to 2, 4, 8, 16, 32, 64, or 128 Kbytes. A larger stripe size produces higher read performance. If your computer regularly performs random read requests, choose a smaller stripe size. The default is 64 Kbytes. c. Select the read policy. The read ahead parameter enables the read-ahead feature for the logical drive. You can set this parameter to No Read Configuring RAID Arrays and Logical Drives Version 1.0 Copyright © 2003 by LSI Logic Corporation. All rights reserved. 1-15 Ahead, Read-ahead, or Adaptive. No Read Ahead is the default setting. No Read Ahead specifies that the controller does not use read-ahead for the current logical drive. Readahead specifies that the controller uses read-ahead for the current logical drive. Adaptive specifies that the controller begins using read-ahead if the two most recent disk accesses occurred in sequential sectors. d. Select the write policy. You can set the write policy to Write Back or Write Thru. The default setting is Write Thru caching. In Write Back caching, the controller sends a data transfer completion signal to the host when the controller cache receives all the data in a transaction. In Write Thru caching, the controller sends a data transfer completion signal to the host after the disk subsystem receives all the data in a transaction. Write Thru caching has a data security advantage over write-back caching. Write Back caching has a performance advantage over Write Thru caching. Caution: Do not use write back caching for any logical drive in a Novell NetWare volume. e. Select the cache policy. The cache policy applies to reads on a specific logical drive. The default is Direct I/O. It does not affect the read ahead cache. The options are Cached I/O or Direct I/O. Cached I/O buffers all reads in cache memory and is the default setting. Direct I/O does not buffer reads in cache memory. Direct I/O does not override the cache policy settings. Direct I/O transfers data to cache and the host concurrently. If the same data block is read again, the host reads it from cache memory. f. Configure the spanning mode. Enable or disable the spanning mode for the current logical drive. If spanning is enabled, the logical drive can occupy space in more than one array. If spanning is disabled, the logical drive can occupy space in only one array. To span arrays, the arrays must have the same stripe width and must be consecutively numbered. If these criteria are not met, CU ignores the span setting. 1-16 WebBIOS Configuration Utility Version 1.0 Copyright © 2003 by LSI Logic Corporation. All rights reserved. g. Select the size of the logical drive in Mbytes. h. Click on the Accept button to accept the changes or click on the Reset button to delete the changes and return to the previous settings. i. Step 7. Click on Next. Check the configuration preview. The WebBIOS CU displays a preview of the configuration. Step 8. Click on Accept to save the configuration or click on Back to return to the previous screens and change the configuration.
