Lippis Report 209: Cisco Launches New Catalyst 2960-X Access Switches

June 24th, 2013

nicklippis.jpgBy all accounts, Cisco’s Catalyst access switch, the 2960-S/SF is the most widely deployed Ethernet switching platform in the world. It’s a hardware platform that offers 40Gbs of stack bandwidth, enough to support a stack of four switches, 2MB of buffer memory and four hardware queues. But while this platform has served Cisco’s customers exceedingly well, this July, a new Catalyst 2960 will be available—simply called the Catalyst 2960-X. Cisco promises that the 2960-X will double every benchmark of the 2960-S, as well as add a series of features that improve the platform’s ability to scale intelligently while increasing security and simplicity of deployment and operations. In this Lippis Report Research Note, we review the latest edition of the most popular access switch on the planet, the Cisco Catalyst 2960-X.

March 25th, 2013

by IDC Brad Casemore, sponsored by IBM System Networking

As the use of server virtualization has matured, IT organizations are realizing they cannot achieve an optimized and agile datacenter unless the network architecture is designed to support converged systems. Therefore, any approach to converged systems that leaves networking as a secondary consideration will be doomed to failure. Fortunately, the industry has responded with networking products that are integrated with converged systems architectures. These solutions deliver the high performance required for next-generation datacenters. This approach delivers benefits in several areas, including optimization of physical and virtual resources, reduction in ongoing management of virtual machines, increased security, and IT agility. This white paper describes the business and economic advantages of an intelligent datacenter network for converged system applications.

by IBM System Networking

Data centers are undergoing a major transition toward a smarter, more dynamic infrastructure. More flexible IT architectures are emerging to address the demands of current business applications and new areas, such as cloud computing, multitenancy, bring your own device (BYOD), big data, and analytics. As part of the dynamic infrastructure trend, the role of data center networks is also changing. It is causing businesses to re-evaluate their current networks, which were never designed to handle modern workloads and applications. IBM’s Open Data Center Interoperable Network or ODIN addresses many of the key problems faced by modern data networks, including automation, integration, and management. Compared to classical Ethernet architectures, ODIN fabrics have several distinguishing benefits, which are discussed in this white paper.

Create a flattened, converged, virtualized, standards-based network
by IBM System Networking

An open data center with an interoperable network is a flat, converged, virtualized data center network that is based on open industry standards. Instead of under-utilized devices, multi-tier networks, and complex management environments, the modern data center is characterized by highly utilized servers running multiple VMs, flattened, lower latency networks and automated, integrated management tools. New software-defined network approaches (including overlay networks and OpenFlow standards) greatly simplify the implementation of features such as dynamic workload provisioning, load balancing, and redundant paths for high availability and network reconfiguration. Further, high-bandwidth links between virtualized data center resources may extend across multiple data center locations to provide business continuity and backup/recovery of mission-critical data. A highly virtualized data center offers greater resource utilization and lower costs. This new network infrastructure also simplifies management and addresses network issues such as latency, resilience, and multi-tenant support for public and private cloud environments. By taking advantage of IBM’s Open Interoperable Networking (ODIN) design approach, enterprises can design a cost-effective and manageable data center that fully uses the potential of virtualization, and gives customers the flexibility to migrate to federated data centers, in which computing, storage, and net-work resources may be treated as dynamically provisioned resource pools that can be rapidly partitioned into any desired configuration.

August 14th, 2012

By Quocirca

UK analyst firm, Quocirca, describes why fast and intelligent system networks, such as IBM’s, are of critical importance for the smarter data centre. As networking technology has standardised around Ethernet, the perception has grown that it has also commoditised. However, as technical architectures evolve to keep pace with the impact of virtualisation, cloud computing and high-performance workloads, the needs around networking are also changing. This is driving data centre operators to understand how recent performance advances and standards-based innovations in system networking infrastructures can meet the performance, scalability and agility requirements of today’s data centres.

Lippis Report 185: Why Software-Defined Networking and Virtualized Networking Are Inexplicably Linked

January 29th, 2012

Computer networking vendors have been increasing the speed and port density of their Ethernet switches while reducing power draw and price per port. But while Ethernet switching hardware marches on linearly, thanks to 10, 40 and 100GbE, networking software is taking a different historical path as the pace of compute and network technology evolution has diverged, with networking lagging. Highly virtualized server deployment has broken traditional networking approaches on multiple levels, for example. In response, the industry is now developing a “virtualized infrastructure” or “stack” to add network flexibility. To close the technology gap, Software-Defined Networking (SDN) is promoted as the new “organizing principle” to deliver network software and service value. While it will be, likely, years before SDN’s organizing principles take hold, I propose that these two industry activities are inexplicably linked and phased; here’s why…
