  • Superconvergence
    THE FUTURE OF DATA CENTER CONSOLIDATION: SUPERCONVERGENCE 1SHAIKH ABDUL AZEEM, 2SATYENDRA KUMAR SHARMA 1 2 Research Scholar, Dean, Faculty of Engineering 1,2,Department of Computer Science, Pacific Academy of Higher Education & Research University, Udaipur, Rajasthan, India E-mail: [email protected], 2 [email protected] Abstract - Convergence in industries is creating tremendous new opportunities and new modes for technology innovation. Convergence providing greater risk management, greater control mechanisms, greater consistency and predictability and greater cost reduction. Convergence with the view of network convergence is leading current IT infrastructure to new levels of efficiency through greater integration and centralization. Convergence is the name where advancements in compute, storage, and network are converging to enable new capabilities, reduction in cost, and introduction of new scale of computing which are previously unimaginable. Performance, resiliency, and scalability are the demands of modern cloud computing environment. The next generation of converged infrastructure, the superconvergence, is poised to provide exactly that. Companies are enabling a giant leap in cloud performance through converged storage, networking, and server systems. This paper provides details regarding the next generation of IT Infrastructure development, the superconvergence. Keywords - siloed, CI, HCI, SCI, Data Centre, Unified Platform, NVMeoF I. INTRODUCTION As the convergence is getting developed, super convergence solutions are coming into the market This is the era of convergence. Once converge system because of this naturally the silos of earlier IT implemented properly, then it can virtualize more Infrastructure implementations management are applications and desktops by just carrying a bit of getting disappear, and the possibility of a true single more resource power.

  • Vmware Vsan SAP | Solution Overview
    SOLUTION OVERVIEW VMware Virtual SAN SAP Applications Hyper-Converged Infrastructure for Business Critical Applications Customers deploying Business Critical Applications (BCAs) have requirements such as stringent SLAs, sustained high performance, and continued application availability. It is a major challenge for organizations to manage data storage in these environments. Common issues in using traditional storage solutions for BCAs include inadequate performance, storage inefficiency, difficulty to scale, complex management, and high deployment and operating costs. VMware, the market leader in Hyper-Converged Infrastructure (HCI), enables low cost and high performance next- generation HCI solutions through the proven VMware Hyper-Converged Software (VMware HCS) stack. The natively integrated VMware HCS combines radically simple VMware Virtual SAN™ storage, the market-leading vSphere hypervisor, and the vCenter Server unified management solution all on the broadest and deepest set of HCI deployment options. Virtual SAN is enterprise-class storage that is uniquely embedded in the hypervisor. Virtual SAN delivers flash-optimized, high-performance hyper-converged storage for any virtualized application at a fraction of the cost of traditional, purpose- built storage and other less-efficient HCI solutions. VMware has completed extensive technical validation to demonstrate Virtual SAN as an ideal storage platform for a variety of BCAs. A recent Virtual SAN customer survey also revealed that more than 60% of customers run their BCAs on Virtual SAN today, making BCA the most common use case. Why Virtual SAN for SAP Landscapes? Customers wanting to modernize their existing complex SAP environments can leverage Virtual SAN, running on both VMware and SAP certified x86 servers, to eliminate traditional IT silos of compute, storage, and networking.
