Three versions of the RAID controller board are used in conjunction with Intergraph’s host servers: DAC960P, DAC960PD, and MegaRAID. DAC960P Controller DAC960P has two independent RAID SCSI bus channels (0 and 1), each using a separate 53C720 SCSI controller.

    DAC960PD Controller DAC960PD has three independent RAID SCSI bus channels (0, 1, and 2), each using a separate 53C720 SCSI controller. This allows the system to read or write data on several disk drives simultaneously. The DAC960PD RAID controller board is shown in the following figure.

Included are examples for striped, mirrored, and other performance options and a brief discussion of database applications. Also included are the differences in RAID mode performance and data integrity.

  • Page 165: Mirrored Raid Performance

    Performance will benefit because the separate channels work independently of each other. Multiple I/O requests can occur simultaneously since they are on separate channels of the controller. An extension of this technique is to stripe not only across multiple SCSI channels on a single controller but to stripe across multiple controllers.

  • Page 166: Tagged Command Queuing

    Tagged Command Queuing intelligently orders the seeks which improves performance for random accesses. Controller Write Back and Read Ahead Caching allow files to be read and written most efficiently for those applications accessing large, sequential data and striping across multiple disks and RAID controller channels. Tagged Command Queuing This option allows the I/O subsystem to queue requests and reorder them into the most efficient order before retrieving them from the disk.

  • Page 167: Raid Mode Performance And Data Integrity Differences

    For maximum performance in a database, Log or Redo Log access is sequential I/O data; you should separate sequential I/O data from random I/O data. Data access is usually random for On-line Transaction Processing (OLTP) applications. The optimal performance strategy is to stripe the data across devices to distribute the I/O data and minimize I/O contention.
