    APPENDIX B: Event Logs www.gateway.com Overview StorView has the ability to manage the events generated by the controller, SES processors, or SAF-TE processes. StorView also has its own unique events that are related to the StorView server component of the software. Events can be used to assist with troubleshooting, monitoring components, and determining the status of hardware components, logical drives, and arrays.

  • Page 123: Accessing And Navigating The Storview Event Log

    Accessing and navigating the StorView event log The time stamp for each event in the StorView log is the exact time the event was received by StorView and can be slightly different from the actual time the event occurred in the controller log. After synchronization, events that occurred while the StorView server was down are marked with an additional string in the event description which displays the actual time stamp that event occurred.

  • Page 147: Command Size - Alignment Statistics

    Command size - alignment statistics Statistic Description Reads This is the average number of MBs transferred in the last few seconds from the logical drives, controllers, or ports. This value is expressed in MB/seconds. Writes This is the average number of MBs transferred in the last few seconds to the logical drives, controllers, or ports.
  • Page 148 APPENDIX C: Statistics www.gateway.com Statistic Description Command Size Expressed in the percentage of commands whose size is specified for reads and writes. The values are displayed with a horizontal bar for each value. The lack of a bar displayed for a specific value indicates it is 0% (or less than 1%).

  • Page 149: Read-Ahead Statistics

    Read-Ahead statistics Read-Ahead statistics If sequential read commands are sent to the controller, it assumes that the commands which follow may also be sequential. The controller can go and perform a read of the data, before the host requests it. This improves performance, particularly for smaller reads.

  • Page 150: Command Cluster Statistics

    APPENDIX C: Statistics www.gateway.com Statistic Description Read-Ahead Command Hit Rate This is the percentage of read command hits versus the total number of read commands that have been issued. This gives an indication of the sequential nature of the data access pattern from the host.
  • Page 151 Command cluster statistics Statistic Description Write Cluster Rate This is the percentage of the number of write commands that are part of a cluster versus the total number of write commands that have been issued. This gives an indication of the sequential nature of the data access pattern from the host and of the performance of the writeback cache.

  • Page 154: Introduction

    APPENDIX D: Optimizing RAID 5 Write Performance www.gateway.com Introduction With a typical RAID 5 implementation, there are a number of steps that are performed when data is written to the media. Every write from the host system typically generates two XOR operations and their associated data transfers to two drives.

  • Page 155: Number Of Outstanding Commands

    Access size Number of outstanding commands For the controller to successfully cluster commands, there has to be a number of write commands sent simultaneously. Setting the host to send up to 64 commands should prove adequate. Alternatively, enabling writeback cache has a similar effect because the controller can cluster sequential commands even if the host only sends a small number of commands at a time.

  • Page 156: Raid 5 Sub-Array

    APPENDIX D: Optimizing RAID 5 Write Performance www.gateway.com RAID 5 sub-array The difficulty in realizing the maximum performance possible introduces the concept of a sub-array. Suppose an array consisted of two RAID 5 sets (see the table on page 148). If these are then striped, the resulting array would appear as shown below.

  • Page 157: Faster Rebuild

    Summary Faster rebuild A rebuild operation must read data and calculate parity from all the remaining drives in the RAID set. If multiple sub-arrays are used, this means that it is only necessary to read the data from the remaining drives in the sub-array, not all of the drives in the array.
