Scaling SAN Connectivity on VMware

VMware and blade servers have taken the IT world by storm. Virtual server use has grown over 50 percent, and blade servers account for 12.5 percent of all new servers. Can you incorporate them into your existing frameworks? Yes. Routers can scale server numbers with virtual interfaces, and with fibre channel storage area network (SAN) connectivity, you can reduce testing and development costs in VMware environments.

The Need to Rethink the WAN

Technological advances have evolved at an exponential rate over recent decades—we’ve seen the advent of the Internet, cloud computing, virtualization, and several other technologies. But the wide area network (WAN) technologies that are currently in use in most branch offices have changed little since the 1990s.

Business environments today are experiencing unprecedented growth and change, and IT departments are losing visibility and control. Traditional WAN technologies are a mismatch for modern branch networks that need to be up and running quickly. The demand for adaptability, awareness of costs, and the need to run and monitor business-critical processes are indicating the necessity for a new WAN technology paradigm.

New WAN services based on the latest technologies have not been deployed by traditional service providers, primarily because they require an initial financial outlay which companies are not prepared to make. But they are poised to succeed multiprotocol label switching (MPLS), and are the most viable alternative for supporting application performance while dealing with increased network traffic and the connectivity demands of cloud computing and mobile access.

In this white paper, the characteristics of WAN technology and the limitations of traditional WAN technology, including complexity, are explored. This paper also discusses some new approaches, such as a hybrid WAN, which are better suited to supporting fast-changing business and technology environments.  Read More

Are you adopting cloud applications in your enterprise and looking for ways to assure wide area network (WAN) performance? Planning to increase branch bandwidth capacity and looking for ways to do it efficiently? This whitepaper explores trends supporting the adoption of hybrid WAN.

Hybrid WAN has arrived. WANs need to power up to the next level in terms of providing reliable connectivity to cloud services, delivering better price performance, and supporting business-critical applications.

Hybrid WANs leverage both private circuits as well as broadband Internet in an integrated architecture. Additionally, hybrid deployment is an ideal architecture for building a hybrid WAN. Learn about the key requirements for an optimized branch office WAN and the advantages of implementing a cloud-delivered solution. Read More

The Operational Data Lake: Your On Ramp to Big Data

Companies recognize the need to integrate big data into their real-time analytics and operations, but this poses a lot of technical and resource challenges. Meanwhile, those organizations that have operational data stores (ODSs) in place find that, while useful, they are expensive to scale. The ODS gives real-time visibility into operational data. While more cost-effective than a data warehouse, it uses outdated scaling technology, and performance upgrades require very specialized hardware. Plus, ODSs just can't handle the volume of data that has become a matter of fact for businesses today.

This white paper discusses the concept of the operational data lake, and its potential as an on-ramp to big data by upgrading outdated ODSs. Companies that are building a use case for big data, or those considering an upgrade to their ODS, may benefit from this stepping stone. With a Hadoop relational database management system (RDBMS), companies can expand their big data practices at their own pace. Read More

How to Use a Network Appliance SAN for Server and Storage Consolidation

If you’re dealing with increasing demands on your server storage by adding servers one at a time, the number of servers is growing hand in hand with management complexity, while stretching your IT budget. Make sure your data assets are covered—find out how server and storage consolidation storage systems can simplify storage management, increase flexibility, and advance data protection and disaster recovery. Read More

Extending SAN Connectivity for Engenio Arrays

The storage industry provides an abundance of white papers discussing the ever-changing data management and retention regulations, the need for business continuity, and disaster recovery. The core of these data services is the ability to copy, move, and replicate data—locally and far away. Unfortunately, SANs only reach about 10 km. IT managers need to share, protect, and move data much farther than that. Find out how. Read More

Scaling SAN Fabric Throughput Using 4Gb-per-second HBAs

An ever-increasing demand on storage area networks (SANs) has meant a necessary evolution of throughput standards. SAN administrators are now burdened with multiple generations of SAN host bus adaptors (HBAs)—and unwieldy management overhead. A scalable HBA architecture might provide just the functions you need to address your cost, performance, backward compatibility, and future scalability concerns. Read More
