- Worked on development of a deduplicating filesystem based on ext2/ext3 kernel module in Linux. The ext2 filesystem was modified to perform deduplication of incoming data to eliminate redundant block writes and improve performance of virtual machines by 500%. - Development of features and bug fixing on 'Atlantis ILIO', which is a distributed server application to manage and enhance the performance of virtual machine disk images. This product is implemented in python. - Worked on converting ILIO from a centralized architecture to a distributed architecture to support larger scale of users and workload. - Built a Linux live-cd based installer for ILIO. This involved development of modules for setting up VMware ESX server and configuration of virtual machines and applications. The installer was built as a python application which itself ran on a virtual machine. - Wrote a Windows MFC application to monitor and report health of Virtual Machines. This application runs on user virtual machines and responds to commands sent over a TCP/IP socket. - Implemented a high availability solution for failover of services provided by ILIO using heartbeat, DRBD (Distributed Replicated Block Device) and OCFS2 (Oracle Clustered File System)
