PPT-Distributed Replication

Lecture 11 Oct 6 th 2016 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.
