    Description
    The #Dell PowerEdge R820 rack server is engineered for enterprise-grade #virtualization and mission-critical workloads. With four Intel® Xeon® E5-4600 processors delivering up to 32 cores and 2.5 MB cache per core, this #quad-socket server offers unparalleled compute density. Its 2U form factor and up to 1.5 TB of DDR3 memory support large-scale virtual machine deployments, making it ideal for both mid-sized and large data centers. Designed to accelerate #high-performance computing and data analytics, the R820’s flexible I/O includes seven PCIe slots and optional hot-plug Express Flash SSDs.

    Data warehousing solutions benefit from the ability to house up to 16 hot-plug 2.5-inch drives internally, while dual RAID controller support ensures redundancy and performance for #data warehousing and database workloads. For #VDI deployments, the R820’s large memory footprint, optional GPU acceleration, and Dell Select Network Adapters provide the low-latency, high-throughput network performance required by virtual desktop infrastructures. Built-in management tools such as iDRAC7 with Lifecycle Controller simplify deployment, monitoring, and updates in both physical and virtual environments.

    Usage Scenarios
    Enterprises seeking to consolidate physical servers onto virtual platforms will find the R820’s memory density and CPU core count ideal for large-scale #virtualization. Hosting hundreds of virtual machines with minimal latency, it supports mixed workloads—from email and web servers to large database instances—on a single 2U chassis.

    High-throughput #data warehousing and real-time analytics benefit from the R820’s flexible storage options. Combine 15 K SAS HDDs with hot-plug Express Flash SSDs to create tiered storage architectures, accelerating both transactional and batch data processing for business intelligence applications.

    For #VDI and GPU-accelerated tasks in engineering and design, the R820’s optional graphics cards and large memory footprint deliver responsive user experiences. By offloading graphics rendering to dedicated GPUs, virtual desktops achieve near-native performance for CAD, simulation, and multimedia workloads.
