Interposed Request Routing for Scalable Network Storage

Abstract
This paper explores interposed request
routing in Slice, a new storage system architecture for high-speed networks incorporating network-
attached block storage. Slice interposes a request
switching filter— called a µproxy —along each
client's network path to the storage service (e.g.,
in a network adapter or switch). The µproxy intercepts request traffic and distributes it across a server
ensemble. We propose request routing schemes for
I/O and file service traffic, and explore their effect
on service structure.
The Slice prototype uses a packet lter µproxy
to virtualize the standard Network File System
(NFS) protocol, presenting to NFS clients a unified shared file volume with scalable bandwidth and
capacity. Experimental results from the industry-
standard SPECsfs97 workload demonstrate that
the architecture enables construction of powerful
network-attached storage services by aggregating
cost-effective components on a switched Gigabit
Ethernet LAN.
