  • Page 19: Array Basics

    Array Basics Adaptec’s RAID adapter and RAID software let you set up and man- age disk arrays on NetWare servers. A disk array is a group of disks that appears to the system as a single virtual disk. This is accom- plished through software.

  • Page 20: Raid 1, Raid 1/0 (Mirrored Disks)

    AHA-3980/3980W/3985/3985W User’s Guide RAID 0 arrays do not store redundant data, so they are not true RAID applications. If one disk fails, the entire array fails and all array data is lost. The fault-tolerance of a RAID 0 array, therefore, is less than that of any single disk in the array.

    RAID Advisory Board (Lino Lakes, Minnesota: September, 1994). Disk Requirements An Adaptec array is an array that was set up using Adaptec’s RAID software. Adaptec’s RAID software lets you create up to four boota- ble or nonbootable arrays of SCSI disks. The following sections describe the disk requirements of Adaptec arrays.

    Instructions for using these utilities are included. Default AHA-398x Settings AHA-398x RAID adapters have the default settings shown in the following table. Some settings apply to the RAID adapter or chan- nels; other settings apply individually to each device on the SCSI bus.

  • Page 122: Basic Channel Settings

    Each channel has its own setting. The default shown is for each channel. For AHA-3980W and AHA-3985W, the effective transfer rates are twice as fast as the settings shown in the SCSI Select screen because the adapters transfer 16 bits (2 bytes) per transfer. Basic Channel Settings Each channel has the default settings described here for SCSI ID, parity checking, and termination.

  • Page 123: Scsi Parity Checking

    Normally, you should leave the default setting, because most SCSI devices support synchronous negotiation and because synchronous data transfer is faster. AHA-3980/3980W/3985/3985W User’s Guide Stock Number: 510810-00, Rev. D Print Spec Number: 493479-00 Current Date: 3/1/99...
