    Using This Guide This User’s Guide provides a quick reference to information about your S1300 Disk Array Unit (DAU). Its goal is to familiarize you with your DAU and the tasks necessary for setting up your DAU, using the DAU, and configuring and upgrading the DAU. This guide assumes that the reader is already familiar with the host system, Fibre Channel technology, and operating system environments in which the DAU will be installed.

    For RAID level 3 and 5 redundancy, a consistency check will involve reading all associated data blocks, computing parity, reading parity, and verifying that the computed parity matches the read parity.

  • Page 95 When something is fault-tolerant it is resistant to failure. A RAID 1 mirrored subsystem, for example, is fault-tolerant because it can still provide disk I/O if one of the disk drives in a mirrored system fails. F_Port A port in the fabric where an N_port or NL_port may attach. 2 Glossary This Manual:http://www.manuallib.com/nec/s1300ug-disk-array-unit-user-guide.html...
