  • H8716.2 EMC Symmetrix Vmaxe Storage System, Spec Sheet
    EMC SYMMETRIX VMAXe STORAGE SYSTEM EMC® Symmetrix® VMAXe™ with the Enginuity™ operating environment delivers a multi- controller, scale-out architecture with consolidation and efficiency for the enterprise. As the newest member of the Symmetrix series, VMAXe utilizes the same revolutionary EMC Virtual Matrix Architecture™ as EMC VMAX™ systems. SPECIFICATIONS ARCHITECTURE The Virtual Matrix Architecture enables IT departments to build storage systems that tran- scend the physical constraint of competing array architectures. The architecture allows scal- ing of system resources through common and fully redundant building blocks called VMAXe series engines. A single VMAXe engine provides the complete foundation for a high-availability storage array. Each VMAXe engine contains two Symmetrix VMAXe directors and redundant interfaces to the EMC Virtual Matrix™ interconnect. Each Symmetrix VMAXe director consolidates front-end, global memory, and back-end functions, enabling direct memory access to data for opti- mized I/O operations. Up to four VMAXe engines can be interconnected via a set of multiple active fabrics that provide scalable performance and high availability. VMAXe engines can be added non-disruptively to provide linear scale-out of Symmetrix system resources. A single-engine Symmetrix VMAXe can start with as little as 24 drives, scaling up to four engines supporting 1,080 drives for a maximum usable capacity of up to 1.5 petabytes. VMAXe engine one and VMAXe engine two can support up to 240 drives per engine. VMAXe engines three and four can support up to 300 drives per engine. A fully configured 1,080- drive system is comprised of four integrated system bays and three storage bays.

  • Proof, Not Promises: Creating the Trusted Cloud
    EMC’S VISION FOR TRUST IN THE CLOUD Proof, not Promises: Creating the Trusted Cloud EXECUTIVE SUMMARY Clouds and virtualization offer powerful new ways to manage and use digital information, but they also create new complexities for organizations in meeting the fundamental challenge of getting the right information to the right people over an infrastructure that they can trust. Why? Because clouds and virtualization irrevocably change the nature of control and visibility. Infrastructure becomes virtual, not physical. People access infrastructure from devices that are outside of IT’s direct control. Information moves with incredible speed across networks and the cloud, making it hard to know where sensitive information resides. And with an IT infrastructure that is virtual and shared via the cloud, organizations must learn new ways to achieve visibility into risks, threats, and compliance performance. The good news is forward-thinking businesses can clear these hurdles today. The formula for building trust in the cloud is to achieve control over and visibility into the cloud’s infrastructure, identities, and information. The technologies needed to establish this level of cloud control and visibility already exist. Organizations are applying these technologies in creative ways to build trusted clouds that can meet the most rigorous security and compliance requirements while delivering the flexibility, fluidity, and massive scale that hold such business promise for organizations worldwide. EMC PERSpecTIVE THE CHALLENGE Over the decades, IT architecture and platform strategies have evolved from mainframe to client-server to the Web. Still, one of the fundamental goals of IT organizations endures: that is, getting the right information to the right people over a trusted infrastructure so information can be leveraged for business advantage.
