Staff Engineer @ * Staff Engineer, July 2015 - Present * Senior MTS, July 2013 - June 2015 * MTS, July 2012 - June 2013 Hypervisor I/O Performance Team + Hypervisor networking and storage performance analysis and optimization. ** Performance analysis and optimization across multiple areas in vSphere's Networking and Storage stack: *** Networking: **** VMware NSX-MH datapath **** New features in vSphere NetQueue including low-latency support, new load balancing algorithms, and performance tuning *** Storage: **** vSphere APIs for IO Filtering (VAIO) ** CPU cost profiling for vSphere's Networking and Storage stack ** Benchmark framework for virtualized networks ** Filed five patents in the first three years at VMware ** First authored one paper accepted as one of 30 research talks in 2015 internal annual R&D conference (out of 400+ submissions) + I/O Analyzer Development (http://labs.vmware.com/flings/io-analyzer) ** I/O Analyzer is the second most downloaded VMware fling tools*. It provides a simple and standardized way of measuring storage performance in VMware vSphere virtualized environments. I/O Analyzer has become a popular tool to benchmark VMware Virtual SAN (VSAN) performance. (* Based on 2013-2014 Fling Website Statistics.) + Network Performance Analysis Framework for Virtualized Networks ** Mentored two interns to develop an internal tool for analyzing packet traces and network performance for virtualized networks.
