Oracle Solaris 11 and Pluribus - application-awareness in the cloud

Talk to any executive of any leading enterprise company and they will tell you that they are embracing cloud computing for the future of their business.  And with the rapid growth of turnkey cloud computing solutions, the network fabric carrying the application packets is emerging as a key focus to drive greater performance, reliability, and efficiency of the application.  Networks need to be able to prioritize packet flow according to the importance of the application.  So if an application is of high importance to their business, the network fabric should be able to know that, and provide the necessary resource to ensure high performance of that application is delivered.

Oracle Solaris 11.2 and Pluribus Networks are providing an integrated solution for doing just that.
You can read about it in a recently release solution brief: 

Oracle Solaris 11 and Pluribus Networks - Enabling Application-Driven SDN in the Cloud

This is an integrated solution for controlling the network in real-time, by combining Oracle Solaris 11.2 built-in application driven software-defined networking (SDN) with Pluribus Networks bare-metal network Hypervisor.   This solution offers fine-grained QoS services, allowing for different tenants, applications, and even flow within applications, to be assigned SLAs to leverage the high-end router-class traffic manager and the network processing unit on the Pluribus platform. Applications become network aware so they can monitor congestions, errors, and latency across the fabric, allowing them to dynamically adjust their network resource requests.

In addition, there is a short (6 min) video interview on this topic with Founder and CTO of Pluribus Networks, Sunay Tripathi:  Oracle and Pluribus Ally on Software Defined Networking

Configuring automatically multiple NICs at installation time with Solaris 11.2

Solaris 11.2 comes with several new and major features such as the Unified Archives, Open Stack integration and kernel zones to name a few. Alongside those major features many smaller but none the less useful enhancements are also introduced. One particular enhancement that has made my life easier is the possibility to automatically configure multiple NICs (network interface cards) at installation time.

After installing Solaris 11, on bare metal or in a Zone, the system needs to be configured at first boot. By default this process is manual: a system configuration wizard walks the user through different steps in order to gather such system parameters as the host name, IP address, net mask, time zone, root passwords and so on. Of course there exists a mechanism to make this process hands-off and fully part of the installation process. In order to do so a system configuration profile XML file needs to be provided at installation time, containing all the information needed to configure automatically the system. However so far, Solaris 11 only allowed the automatic configuration of a single NIC. On systems with several NICs, it was still necessary to configure all the remaining network interfaces, either manually, or by setting up a first boot script mechanism to perform this extra task.

In Solaris 11.2 this extra step becomes history: it is now possible to specify multiple NICs in the system configuration profile XML file in order get all NICs configured automatically during installation time. So how does it work? The best way demonstrating this would be to go through an example by installing a Solaris 11 Zone with two NICs and configuring them automatically. The first step is to create a simple Solaris 11 Zone with two NICs following Listing 1.
