Small Review of  Dell r820 Server Expand  Power Capacity

The R820 can accommodate up to four processors And is currently available with a selection of eight distinct members of the Intel Xeon E5-4600 processor family, which include as many as eight cores per processor depending on version. Ours uses the Intel Xeon E5-4650. The R820 may also leverage up to two actively-cooled 75W NVIDIA Quadro 2000GPUs that in turn provide up to 1GB of committed GDDR5 memory, less GPU accelerator support than can be obtained from the PowerEdge R720. Support for as many as 7 PCIe cards supplies added customization and upgrade paths.

Dell Provides the PowerEdge R820 in four inner Storage configurations: 8 x 2.5-inch drives, 8 x 2.5-inch drives and 4 x 2.5-inch Express Flash PCIe SSDs, 8 + 8 x 2.5-inch drives, or 16 x 2.5-inch drives. The PowerEdge R820 supports Express Flash drives with capacities of 175GB or even 350GB that can be used as primary storage or as CacheCade internal tiered storage when coupled with designated PERC controls. Along with encouraging up to 1.5TB of unbuffered DIMMs (UDIMM) and registered DIMMs (RDIMM), the R820 supports load decreased DIMMs (LRDIMM). LRDIMM uses a buffer to reduce memory loading and provide greater density at the cost of increased latency. In our configuration, Dell provided four 146GB 15K SAS HDDs connected to their Perc H710 RAID card.

Dell Select Network Adapter options for your R820 Include lots of LAN on Motherboard (LOM) cards in a proprietary network daughter card (NDC) form factors. NDC options supported on the PowerEdge R820 include a selection of 1GbE and 10GbE port cards including 1000 Base-T, 10Gb Base-T and 10Gb SFP+.

The PowerEdge R820 supports hot-swappable cooling system Lovers in an N+1 configuration, allowing a technician to substitute any 1 fan at one time. As a 12th generation PowerEdge, the R820 also incorporates Dell’s Fresh Air cooling system design that permits the server to operate over 35°C/95°F to reduce energy intake and related cooling expenses. The 12th generation PowerEdge platform offers user-selectable cooling configurations for servers which use additional equipment, such as PCIe cards, which may result in automated cooling systems to invert if sensors aren’t positioned to discover hot spots. Among the Enterprise Storage Lab’s selection of tier-one servers, the PowerEdge R720 and HP ProLiant DL380p Gen8 offer this feature although Lenovo’s ThinkServer RD630 does not.

The PowerEdge R820 supports up to 2 power supplies With redundancy, auto-sensing and auto-switching rated at 750W AC, 1100W AC, or 1100W DC based on the requirements of the client’s intended configuration. 12th production PowerEdge systems may limit power consumption inside a datacenter is by capping the system at a user-defined limit when processors are throttled down till the target is attained. This is very useful when presenting new servers if there strict power or thermal limitations. Our review unit came equipped with two 1100W AC power supplies.

Front of our PowerEdge R820 reflects its 16-slot 2.5″ storage type element. A lockable bezel is available as an alternative. At left is a power switch and indicator, non-maskable interrupt (NMI) for monitoring, VGA monitor connection, a simple LCD controller panel and a vFlash SD media reader to be used with iDRAC alongside two USB 2.0 ports.

The rear of this unit Provides access to up to two Hot-plug power supplies and associated indicators, network connectivity through Dell’s Select Network Adapter family, 2 USB.0 interfaces, iDRAC7 interface, video connector and serial connector. Dell’s Quick Resource Locator is a QR code which links to support and administrative reference material specific to the server version that can be found in many areas on the chassis.

Advantage of Dell r820 Server Expand  Power Capacity

 Scalable, Balanced performance

Optimize application Functionality for compact virtualization or scale out 4-socket workloads using the R830’s remarkable resources.

Intel® Xeon® processor E5-4600 v4 architecture

80 percent growth in computational power over R820

As much as 3TB DDR4 memory in 48 DIMMs

As much as 16 SSDs or traditional HDDs, well suited to data-intensive workloads

Having a recognizable 2U rack form factor, the R830 Is an ideal numerical server for mainstream data centers.

Workload-centric adaptability and flexibility

Performing different compute-intensive, memory-bound Or I/O-centric workloads, the R830 can easily adapt to any application. When it’s Oracle RAC or Microsoft® SQL Server®, the available tools can be fine-tuned to maximize application performance and PCIe SSD cards can be inserted to significantly increase I/O and enhance CPU utilization. In addition, the redundant embedded hypervisors help ensure a fail-safe virtual surroundings.

Performance:

Intel’s C602 chipset supports up to four Intel Xeon E5-4600 or E5-4600 v2 processors. Each processor offers four to twelve cores with 2.5MB cache per core delivering around 48 cores in a four processor setup. CPU 1 and 2 are supported on the primary system board and encourage 24 Dimm slots. A processor expansion module (PEM) stacks along with this system board with a QPI connector and supports processors three and four along with 24 additional memory module slots. Several other performance-enhancing features include support for up to 48 DIMM slots, optional front PCIe technologies for SSD’s, support for internal GPU accelerators and seven PCIe Gen3 expansion slots.

Conclusion:

Much like Dell’s PowerEdge R720, the R820 includes a Storage performance advantage over other servers when used in conjunction with front-mounted, hot-swappable Express Flash PCIe storage. Past the hyper-speed storage backplane alternatives, the R820 has other strengths with an impressive maximum of 48 DIMMs allowing up to 1.5TB of DDR3 memory. Being able to hold huge datasets in memory provides an increase to compute-intensive actions that match CacheCade’s increase in storage access speeds.

The 12th creation PowerEdge chassis design has Proven itself to be a flexible physiological platform mounting and serviceability options with most often accessed parts are easy to achieve for support. An impressive assortment of available configurations allow customers to closely fit the demands of their specific program, whereas seven PCIe slots provide lots of flexibility and room to update. From a setup and management perspective, iDRAC7 makes putting the R820 into service about as easy as it gets.

While most server usage cases do not require the Horsepower and density that the R820 supplies, there are many where it makes sense. From the storage standpoint, the Additional CPUs help tremendously when multiple PCIe storage devices are introduced that may gain from the extra cores. FPGAs and other storage controls that may leverage the additional compute power To really stretch out their performance even further can really shine in the R820. That’s exactly how the StorageReview lab intends to showcase the stage over The forthcoming months with performance-centric application tests that illustrate A number of the finest in class storage options offered in this compact 2U powerhouse.
