02 Mar 2013 How to: Build a Private Virtual Network with Zones in Solaris 11 [29973]
Networking with a 'Roll-your-own' Virtual Switch

Courtesy of User 13333379, readers are alerted to Stefan Schneider"s multi-part how-to on building a private virtual network with Solaris 11 Zones. Among the several tasks Schneider leads readers through are:

  • Creating a virtual switch (gbswitch0) inside your Solaris 11 servers
  • Creating virtual network interfaces which will be attached to the virtual switch
  • Creating zones which will use the virtual switch
  • Configuring the routing to keep all communication inside your Solaris server
  • Configuring a network address translation (NAT) which allow your internal zones to access external services like DNS
  • Configuring a reverse proxy for the public network interface.

01 Mar 2013 Database Isolation in the Private and Public Cloud [29977]
Oracle RAC in Solaris 11 Zones Generally Does the Job; Use Encapsulation when Security Issues Demand It

The isolation of natively consolidated databases, whether private or public, on a a single shared Oracle Grid Infrastructure can generally be accommodated by the provisions built in to Oracle Database, B.R. Clouse posts, citing "Best Practices for Database Consolidation in Private Clouds" for details. Database clouds hosting databases with security or compliance considerations can be isolated through the encapsulation techniques, either logical or physical, provided by Oracle Database 11g R2 RAC in Solaris 11 Zones. A second white paper, "Encapsulating Oracle Databases with Oracle Solaris 11 Zones," explains this capability. Clouse also recommends the white paper "The Oracle Optimized Solution for Enterprise Database Cloud."

01 Mar 2013 White Paper: Implementing Root Domains with Oracle VM Server for SPARC [29976]
Introduces Root Domain Model as One of Several Architectures Supported by Oracle VM Server for SPARC

"Implementing Root Domains with Oracle VM Server for SPARC," a new Oracle white paper by Mikel Manitius, Michael Ramchand, and Jeff Savit, describes how to use Oracle VM Server for SPARC root domains (domains that are assigned a PCIe bus) along with Solaris zones for maximum performance and a high degree of flexibility. This combination can be used to provide bare-metal performance and eliminate dependencies between domains, and can be a useful alternative to deployments based on service domains and virtual I/O, co-author Savit posts. The paper introduces the root domain model as one of several architectures Oracle VM Server for SPARC product supports.

18 Feb 2013 Five Perspectives on Virtual Networks [29788]
Several Aspects of Virtual Network Creation

Rick Ramsey has gathered five posts on virtual networks by various hands with the intent of making it easier for users to decide which type of virtual network to create. The posts are:

  • "How Networking Works in Virtual Box" by the Fat Bloke

  • "Evaluating Oracle Solaris 11 from Inside Oracle VM Virtual Box" by Yuli Vasiliev

  • "Looking Under the Hood at Networking in Oracle VM Server for x86" by Greg King and Suzanne Zorn

  • "Which Tool Should I Use to Manage Which Virtualization Technology?" by Ginny Henningsen

14 Feb 2013 Network Virtualization and Network Resource Management [29780]
Part 5 of Virtualization Series by Detlef Drewanz

Detlef Drewanz has posted part 5 of his series on virtualization, defining and discussing the features of internal and external network virtualization and network resource management in this segment. Drewanz explains the features that are part of virtualization products, calling them the "glue" that binds all the VMs, zones, and containers together and enables them to communicate among themselves and with the outside world. He then recommends the employment of several types of network resource management tools, including constraints, scheduling, and partitioning.
