About Us

  • Problems We Address

    As the cost of components used in storage appliances has reduced drastically, those cost savings have not trickled down to end user IT consumers. For instance EMC, the leading storage OEM enjoyed 61% gross margin1. A decade ago higher margins in the storage industry were justified because expensive purpose built hardware was needed for building an enterprise storage appliance. However over the past few years, with the introduction of high core count x86 CPUs, 25gbps+ iSCSI, high capacity (14TB) hard drives, low latency and high endurance PCIe/NVME SSDs, meant that all the hardware that goes into a traditional enterprise storage appliance is now available off-the-shelf. Also, the ability for enterprise IT consumers to easily mix and match chassis, motherboards, hard drives, SSDs, and NICs, meant that a storage appliance of any capacity and performance could be put together using off-the-shelf components, provided there was software to do so. This is where we come in. It is our mission to develop software that stitches together off-the-shelf hardware to satisfy the diverse storage needs of any enterprise IT organization, and as a result deliver cost savings to IT organizations, without compromising performance, resilience, and failure resolution times required of enterprise grade storage.

    Company Background

    Virtunet Systems was founded in 2010 with the idea of alleviating storage IO issues within virtualized servers.

    Our first product called VirtuCache, improves the storage performance of VMware VMs by automatically caching ‘hot’ data from any SAN array to any in-host SSD or RAM. Our second product called VirtuStor, clusters together commodity servers and presents this cluster of servers to VMware hosts as an iSCSI appliance.

    Our team is made up of kernel engineers and business folks from various systems and virtualization startups that were ultimately acquired by Intel, Netapp, Alcatel-Lucent, and HP.

    We have been profitable and debt free every year since founding, and we are entirely employee owned.

    We count over 600 enterprise IT departments as customers. IT departments at large organizations like Western Digital, AXA, UCLA, Stanford, Service Now, Verint, Providence Health; OEMs like Seagate, Cisco, Tellabs; service providers like France Telecom, Viasat; many local government IT departments; regional Managed Service Providers; and small business IT departments, use our software.

    Parag Patkar, Founder and CEO

    Parag founded Virtunet Systems with Bappa Sinha in 2010 with the mission to provide easy to use, high performing, and reasonably priced storage for enterprises.

    Parag’s stewardship has resulted in Virtunet becoming a profitable, debt free, and a 100% employee owned organization with invaluable IP in the server storage and virtualization fields in a short span of four years.

    Before founding Virtunet Systems, Parag has had various sales roles of increasing responsibility at Inktomi (acquired by Verity, Autonomy and then HP), and later at Wind River (acquired by Intel). His most recent role was as director of sales at Wind River responsible for the sales of the first-to-market Internet-of-things management platform that let OEMs manage connected devices in the field. After Intel’s acquisition of Wind River, Parag was responsible for all software and services sales to networking and storage OEMs for the North American west coast. Software solutions included embedded virtualization software, IO subsystems, and management frameworks.

    Parag has a Masters and Bachelors in Aerospace Engineering from Indian Institute of Technology, Bombay.
