PPT-Distributed Replication

Lecture 16 Oct 22 nd 2015 Howd we get here Failures amp single systems fault tolerance techniques added redundancy ECC memory RAID etc Conceptually ECC amp RAID both put a master in front of the redundancy to mask it from clients ECC handled by memory controller RAID looks like a very reliable hard drive behind a special controller.

Failures & single systems; fault tolerance techniques added redundancy (ECC memory, RAID, etc.). Conceptually, ECC & RAID both put a “master” in front of the redundancy to mask it from clients -- ECC handled by memory controller, RAID looks like a very reliable hard drive behind a (special) controller.
