Transparently scalable storage --
the EqualLogic Peer Storage Architecture
On storage server networks each storage array is generally a separate
network node. This means it is seen by storage clients as a distinct service
with a distinct address. Growth (scaling) then becomes a very
invasive operation, because many clients will see their resources move.
EqualLogic has created an architecture for transparent storage server
scaling, which we have called the "Peer Storage" architecture.
It allows a storage service to grow transparently, without service downtime.
The systems are self-balancing, requiring essentially no manual tuning.
The talk describes the architecture and key protocols, including areas
of ongoing work.
Paul Koning is co-founder and Chief Technical Officer of EqualLogic
(Nashua, NH). He has been involved in design and implementation of distributed
systems for over 20 years, starting at Digital Equipment with DECnet,
and subsequently at Chipcom, 3Com, Xedia, and Lucent. He was involved
in the definition of the FDDI and ATM standards, and served as chair of
the ATM Forum P-NNI (routing) working group.
