Today organizations and business enterprises of all sizes
need to deal with unprecedented amounts of digital information,
creating challenging demands for mass storage and
on-demand storage services. The current trend of clustered
scale-out storage systems use symmetric active replication
based clustering middleware to provide continuous availability
and high throughput. Such architectures provide significant
gains in terms of cost, scalability and performance
of mass storage and storage services. However, a fundamental
limitation of such an architecture is its vulnerability
to application-induced massive dependent failures of the
clustering middleware. In this paper, we propose hierarchical
middleware architectures that improve availability
and reliability in scale-out storage systems while continuing
to deliver the cost and performance advantages and a
single system image (SSI). Hierarchical middleware architectures
organize critical cluster management services into
an overlay network that provides application fault isolation
and eliminates symmetric clustering middleware as a
single-point-of-failure. We present an in-depth evaluation
of hierarchical middlewares based on an industry-strength
storage system. Our results show that hierarchical architectures
can significantly improve availability and reliability of
scale-out storage clusters.
