Position paper: Towards global storage management and data placement
Alistair Veitch, Erik Riedel, Simon Towers and John Wilkes
Abstract:
As users and companies dependence on shared, networked information
services continues to increase, we will see continued growth in large
data centers and service providers. This will happen both as new
services arise, and as services and servers are consolidated on one
hand (for ease of management, outsourcing, and reduced duplication),
and further distributed on the other hand (for fault-tolerance of
critical services and to accommodate the global reach of companies and
customers). This paper outlines the key research issues associated
with the deployment and management of a global storage system to
support this infrastructure. We build on our success in automatically
managing local storage systems, and discuss how moving to a system of
global data placement raises new challenges and areas of research. We
believe that one of the key attributes of such a storage system is the
ability to flexibly adapt to a variety of application semantics and
requirements as they arise (many applications that will drive
Internet data centers five years from now are only now being sketched
on napkins) and as they change over time.
