  • Page 27: Getting Started With The Subsystem

    3 Getting Started with the Subsystem 3.1 Connecting the RAID Subsystem to the Host This section describes how to connect the EP-2126-SA3 to your host system. The subsystem supports Ultra 320 SCSI LVD interface which provides fast 320MB/s data transfer rates using a 16-bit SCSI bus. Installation of the disk array is very similar to the installation of a standard SCSI drive.

  • Page 28: Introduction

    4 Introduction ProRAID Manager RAID Management Software is an OS-independent Java Application that manages Epica systems via an Ethernet connection. This software is provided on a CD shipped with your Epica system and should be installed on the host system that you will use to manage the system.
  • Page 29 By striping the drives in the array with stripes large enough so that each record falls entirely within one stripe, most records can be evenly distributed across all drives. This keeps all drives in the array busy during heavy load situations. This situation allows all drives to work concurrently on different I/O operations, and thus maximize the number of simultaneous I/O operations that can be performed by the array.
  • Page 30 RAID 3 sector-stripes data across groups of drives, but one drive in the group is dedicated to storing parity information. RAID 3 relies on the embedded ECC in each sector for error detection. In the case of drive failure, data recovery is accomplished by calculating the exclusive OR (XOR) of the information recorded on the remaining drives.
  • Page 31 RAID 6 is similar to RAID 5 in that data protection is achieved by writing parity information to the physical drives in the array. With RAID 6, however, sets of parity data are used. These two sets are different, and each set occupies a capacity equivalent to that of one of the constituent drives.

  • Page 32: Scsi Concepts

    RAID Management The subsystem can implement several different levels of RAID technology. RAID levels supported by the subsystem are shown below. RAID Description Level Drives Block striping is provide, which yields higher performance than with individual drives. There is no redundancy. Drives are paired and mirrored.

    4.3.3 Hot-Swap Drive Replacement The subsystem supports hot-swapping of drives while the system is powered on. A disk may be disconnected, removed or replaced with a different disk without turning off the system. 4.3.4 Disk Failure Detection The subsystem can automatically detect disk failures. It monitors disk activities including the elapsed time on all commands issued to the disks as well as parity errors and other potential problems.
