Solid state is showing up at every level of the storage stack -- as a memory cache, an auxiliary storage tier for hot data that's automatically shuttled between flash and mechanical disk, even as dedicated primary storage, so-called Tier 0. But if funds are limited, where should you use solid state to get the best bang for the buck? In this Network Computing webcast, we'll discuss various deployment options.

Understanding Flat Networks

A flat network or fabric provides more paths through the network and can maximize bandwidth and better support a highly virtualized data center. We'll look at standards-based approaches to designing a flat network, including TRILL and SPB, as well as proprietary implementations. We'll also discuss the implications of moving to a flat network and provide guidance to help you decide if this approach is right for your data center.

3 Paths To Network Convergence

Separate data and storage networks might have been necessary when Fast Ethernet was pitted against speedy, special-purpose Fibre Channel, but Ethernet's evolution has obviated most of the performance differences. We'll examine the trends behind network convergence, share exclusive research, and outline three deployment scenarios for those who want to merge data and storage networks.

Long-Distance LAN

Connecting two data centers for always-on applications is a tricky business. Perhaps the most critical decision is how to link themL keeping the application and virtualization software synchronized requires very low latency between the two data centers.We walk you through the challenges and evaluate the pros and cons of solutions such as VPLS and MLAG, as well dark fiber and dense wave division multiplexing.

Networking In A Virtualized World

Virtualization is rapidly evolving into a core element of next-generation data centers. This expanded role places new strains on the network. This report explore the technical issues exposed by virtualized infrastructure and looks at standards, technologies and best practices that can make your network ready to support virtualization.

Cost-effective Network Architecture: Establish a Fit for Purpose Infrastructure

Real-time communications and collaboration is a game-changer for enterprise network architecture. Today�s enterprise network needs to be a highly focused resource capable of providing a mobile and diverse workforce with efficient, effective access to the tools and applications that drive productivity. Because traditional, general purpose network architectures were not designed to address Unified Communications, new network strategies are needed. This white paper unveils Avaya�s Fit for Purpose infrastruc�ture capabilities that combine performance on the most demanding real-time applications with compelling economics.

Debunking the Myth of the Single-Vendor Network

Gartner recently conducted research to test the theory behind the single-vendor network. They collected information from hundreds of client interactions and performed detailed interviews of nine organizations that introduced a second vendor into their network environments. This white paper details the study, presents the key findings and provides recommendations based on the research. Download this paper today to understand why using a duel-vendor or multivendor solution is a practical approach to building a network.
