Abstract

Shadow migration has been widely used for migrating existing file systems to Solaris servers and the Oracle ZFS Storage Appliance (ZFSSA). Shadow migration is an interposing technology making the data in the old file system immediately available and modifiable in a new file system that "shadow"s the old. In this talk, we will explain how the technology works at a high level and discuss some of the challenges we've faced in optimizing and improving its performance.

Learning Objectives

Understanding use cases of shadow migration in ZFSSA & Solaris
Understanding shadow migration at a high level
Understanding optimization issues for higher performance
