Chapter 8 Terminal Operation 8.1 Power on RAID Enclosure Hardware installation should be completed before powering on your RAID enclosure. Drives must be configured and the controller properly initialized before host computer can access the storage capacity. The configuration and administration utility resides in controller's firmware. Open the initial terminal screen: use arrow keys to move cursor bar through menu items, then press [ENTER] to choose the terminal emulation mode, and [ESC] to return to the previous menu/screen. 8.2 Caching Parameters Optimization Modes Mass storage applications fall into two major categories: database applications and video/imaging applications. The controller supports two embedded optimization modes: Optimization for Random I/O and Optimization for Sequential I/O. Limitations: There are limitations on the optimization modes. First, one optimization mode must be applied to all logical units in a RAID system. Second, once the optimization mode is selected and data written in logical units, the only way to change the optimization Terminal Operation 8-1
8-2 mode is to backup all data to somewhere else, delete all logical configurations of drives, and reboot system. The limitation derives from the consideration with the redundant configuration of controllers. Data inconsistency might occur when a controller pre-configured with optimization mode is used to replace a failed controller with different mode. Database and Transaction-based Applications: this kind of applications usually include SQL server, Oracle server, Informix, or other data base services. These applications keep each transaction within the minimal size, so that I/O transfers will not be clogged by one large transaction. Due to its transaction-based nature, these applications do not read or write a bunch of data in a sequential order. Instead, access to data occurs randomly. The transaction size ranges from 2K to 4K. Transaction-based performance is usually measured in “I/Os per second” or “IOPS.” Video Recording/Playback and Imaging Applications: this kind of application usually belongs to video playback, video post-production editing, or other similar applications. These applications read or write large files from and into storage in a sequential order. The size of each I/O can be 128K, 256K, 512K, or up to 1MB. Performance is measured in “MB/Sec.” When an array works with applications such as video or image oriented applications, the application reads/writes from the drive as large-block, sequential files instead of small-block and randomly accessed files. 1. Optimization for Random I/O: the logical drive, cache memory, and other controller parameters will be adjusted for the use of database/transaction-processing applications. 2. Optimization for Sequential I/O: “Optimization for Sequential I/O” provides larger stripe size (block size, also known as Chunk size) than “Optimization for Random I/O.” Numerous controller’s internal parameters will also be changed to optimize for sequential or random I/O. The change will take effect after the controller resets. The logical drive, cache memory, and other controller internal parameters will be adjusted for the use of video/imaging applications.
