Virtual Network - Part 3 [23914]
Creating Vitual Network Elements
The series on the network virtualization features of Oracle Solaris 11 Express written by Jeff Victor continues with his third post, which deals with the creation of virtual network elements (VNEs). Victor explains that his example employs an old Sun Fire T2000 with a single SPARC CMT (T1) chip and 32GB RAM. He pretends to be implementing a 3-tier architecture in this one system, where each tier is represented by one Solaris zone. This mythical example provides access to an employee database, he continues, and the 3-tier service is named 'emp' and VNEs will use 'emp' in their names to reduce confusion regarding the dozens of VNEs created for the services this system will deliver. Victor remarks on the convenience of the dladm(1M) command in Solaris that one can use to create, destroy and configure datalinks such as VNICs. He illustrates his post with numerous code samples.

Network Virtualization [23883]
Consolidation and Flow Control in Solaris 11 Express
Network virtualization is but one of the several powerful new features in Solaris 11 Express that is the subject of J. Savit's blog post on flow control. Savit's example is an environment with multiple networked hosts on different switches with differing bandwidth requirements. The post shows how, with Solaris 11 Express, it is possible to describe virtual networks to maintain isolation and different network properties, while also establishing flow settings to manage quality of service. It is possible to create virtual network configurations that match the physical one, and control performance properties, Savit asserts. Code samples are included.

Demand for Network Flexibility, Cost Reductions Spotlights Network Virtualization [23833]
Project Crossbow Matures into the NV Features Now Available in Solaris 11 Express
With the imperative to increase network flexibility while minimizing the cost of that initiative, IT staffers are looking to network virtualization (NV), hoping to exploit its potential to reduce cost while increasing network flexibility. Jeff Victor provides some basic information on NV in his blog. He notes that among the benefits of network virtualization are increased architectural flexibility, better bandwidth and latency characteristics, the ability to prioritize network traffic to meet desired performance goals, and lower cost from fewer devices, reduced total power consumption.

Consolidating and Virtualizing Datacenter Networks with Oracles Network Fabric [23792]
Converged Infrastructures Enable Savings of 5x 10x vs. Multi-vendor Implementations
As the Oracle white paper "Consolidating and Virtualizing Datacenter Networks with Oracle's Network Fabric" notes, shifting from traditional datacenter network architectures that call for numerous tiers of networking and parallel networks to support server-to-server, server-to-storage and server-to-LAN traffic, and adopting instead Oracle's converged infrastructures of compute, storage and network components customers can expect substantial reductions in infrastructure and consequent reductions in acquisition, power and cooling, and management costs, along with faster deployment times and greater agility in conforming IT infrastructure to dynamic business needs in the management of their private clouds. The Oracle Exalogic Elastic Cloud and the Oracle Exadata Database Machine are but two examples of Oracle's ability to produce solutions that tightly integrate network services across application infrastructure. Performance gains are in the order of 5X to 10X compared to those involving multi-vendor architectures.

Sun Network QDR InfiniBand Gateway Switch [23611]
A Gateway Is a Gateway Is a Gateway
As he sees it, the Sun Network QDR InfiniBand Gateway Switch enables users to employ Infiniband, with a single cable, as a single fabric on their servers as a gateway to connect to an existing Ethernet network, blogs Joerg Moellenkamp. Citing the FAQs on the Sun Oracle link, he points out that, "The gateway presents itself to the Ethernet fabric as a collection of Ethernet NICs." In other words, no new management issues as a consequence of adopting the gateway.

New Quad Data Rate Infiniband Networking Options for Oracle's Sun Servers [23579]
Putting the I/O Bottleneck Out of Business
Throughput is the operant word in discussions about the new Infiniband networking options for Oracle's Sun servers. Users of the new Oracle Quad Data Rate InfiniBand networking options will find that, "These HCAs provide enterprise datacenters with the high throughput and low latency benefits of InfiniBand, and enable Oracle's Sun servers to run at peak performance by eliminating I/O bottlenecks," in the words of Oracle's release.
