Dell EMC Software Defined Networking (SDN) is a programmatic approach to networking with centrally managed network intelligence. SDN reduces the risk and administrator overhead while improving the overall network efficiency. With Dell EMC Software Defined Networking, the function of traffic control is separated from the network hardware—this allows the network to add new apps and capabilities without consuming much time and money. Who uses Dell EMC Software Defined Networking (SDN) and why? Enterprise IT organizations use SDN to reduce their dependence on expensive hardware, streamline their physical infrastructure and avoid vendor lock in. Powered by SDN, these organizations will have massive scalability and flexible deployment options. The hardware layer is decoupled from the software, resulting in more agility, lesser network downtime and optimal network productivity.
According to the ONF, software defined networking (SDN) is an emerging architecture that is dynamic, manageable, cost Dell EMC Software Defined Networking effective, and adaptable, making it ideal for the high bandwidth, dynamic nature of today’s applications. This architecture decoupled the network control and forwarding functions enabling the network control to become directly programmable and the underlying infrastructure to be abstracted for applications and network services. The OpenFlow protocol is a foundational element for building SDN solutions.” Many vendors have announced support for OpenFlow V1.3. As mentioned, one of the key SDN use cases is traffic engineering. In addition, a defining characteristic of SDN is that it separates the control of the network from the process of forwarding the packets. Staying with the metaphor, one way to think about how SDN concepts could be applied to vehicular traffic involves thinking not of a traditional car, but of a Google inspired, driver less car.

In addition to having multiple ways of implementing network virtualization, other key architectural distinctions between the varying ways that vendors are implementing SDN include the role of dedicated hardware, amount of control functionality that is centralized, and use of protocols such as OpenFlow. One example of that divergence of opinion is that some vendors believe it is possible to fully support network virtualization in the data center without using dedicated hardware and some vendors believe that dedicated hardware is needed at least some times. The survey respondents were asked to indicate if they believed that with the current technologies and products it’s possible to broadly support network virtualization in the data center without using any dedicated hardware? The no responses outnumbered the yes responses by almost a 2:1 ratio.

Vendor neutral OpenStack and industry standard APIs. More infrastructure and application flexibility. More opportunities to innovate and gain critical insights from your data. Accessibility that meets your needs now and in the future. IoT—generated data offers tremendous beneficial potential in areas including real-time medical monitoring for better health, real-time financial transaction analysis for more secure banking, “smart” home devices like thermostats or fans, and mobile devices and wearables.
Network virtualization isn’t a new topic. IT organizations have implemented various forms of network virtualization for years; i.e., VLANs, VPNs, VRF. However, in the context of SDN the phrase network virtualization refers to the creation of logical, virtual networks that are decoupled from the underlying network hardware to ensure the network can better integrate with and support increasingly virtual environments. As previously noted, the predecessor to The Guide was entitled The 2013 Guide to Network Virtualization and SDN. The genesis of that title was that in 2013 there was disagreement in the industry about whether or not SDN and network virtualization were the same thing. Today most of that disagreement has gone away and there is general agreement that network virtualization is a critical SDN application and as described below, there are multiple ways to implement network virtualization. Current storage systems are not equipped for the growing needs of your data.

Every Dell EMC Avamar backup is a full backup, which makes it easy for you to browse, point, and click for a single—step recovery. Dell EMC Avamar provides fast, reliable NAS system backup and recovery via the Dell EMC Avamar NDMP Accelerator node. With this approach, a Level—0 backup is performed only once, during the initial full backup. Subsequent daily full backups are achieved by requesting only Level—1 incremental dumps, and building them into a daily full backup view. This dramatically reduces backup times and the impact on NAS resources, and allows an easier and faster recovery.
Dell EMC Avamar eliminates backup bottlenecks and provides the freedom to consolidate storage and optimize NAS systems—without limiting the number and size of files or volumes—to meet the backup window. With automated multi streaming, Dell EMC Avamar can protect large—scale out NAS systems, including Dell EMC Isilon, by delivering increased throughput to protection storage. Dell EMC Avamar’s Fast Incremental architecture provides an efficient solution to protect high density file systems (HDFS).
Current storage systems are not equipped for the growing needs of your data. An IDC study confirms Dell EMC offers the broadest Software Defined Storage portfolio, powered by Intel Xeon processors, that provides the enterprise-grade agility to support your digital business demands. Software Defined Storage offers elasticity, scale, and simplicity - with no compromises. The cost to store, manage and analyze billions or trillions of data objects just isn’t feasible using traditional storage, given the cost of constantly having to make new hardware investments to keep up with growing data stores.
By decoupling software from hardware, Software Defined Storage makes it possible to simply acquire low—cost commodity hardware instead—reducing the cost of acquiring storage by as much as 50%. To do data analysis in a traditional storage environment, you have to make multiple copies of data or coalesce it from multiple sources. That’s inherently slow, inefficient and unsuited to the amount and variety of IoT—generated data. But software defined cloud storage introduces the concept of a geo-distributed data lake, with the protocolsin place to accept a variety of data on the front end and to perform analytics—in—place wherever edge-device data is collected for rapid—even real-time—data analysis. It also enables analytics at the core on archival data for visibility into ever-increasing data sets.

With Software Defined Storage, enterprises can create giant geo-distributed pools of storage that grow as large as necessary with very little effort on the part of IT and its users. The economic benefits are unprecedented, too, as commodity—based platforms increasingly provide the foundation for next generation storage, replacing more costly purpose-built storage arrays.
And it all starts with understanding what we mean when we talk about Software Defined Storage: it’s an approach to storage system design using the principles of distributed computing that delivers elastic, scale—out, multi—protocol, and geo—distributed capabilities all with a simplified management experience. This is how we will all store more data, and more kinds of data, than we have ever done before.
