I am a Ph.D candidate in the Department of Computer Science at The Ohio State University. I am a member of the Network-Based Computing Laboratory (NBCL), and my advisor is Prof. Dhabaleswar K. (DK) Panda.
My dissertation focuses mainly on designing high-performance, scalable clustered storage systems. My research started with the NFS/RDMA project. The main thrust of this research is to design and develop a high performance RDMA-enabled RPC transport for the NFSv4/NFSv4.1 (pNFS) client and server. We currently have high-performance implementations for both NFS and pNFS. Traditionally, NFS used TCP and UDP as the underlying transport protocol; which may introduce considerable overhead, particularly for high-performance networks like InfiniBand. As InfiniBand and 10 Gigabit Ethernet (10 GbE) increasingly connect geographically disparate compute sites, the ability to seamlessly and transparently share storage resources with reasonable performance is possible. We are currently investigating the feasibility of deploying different block, object and file based protocols in the context of a wide area network interconnected with InfiniBand and 10 GbE.
