26 May 2014 Security Access Control With Solaris Virtualization [36634]
By Thierry Manfe

Numerous Solaris customers consolidate multiple applications or servers on a single platform. The resulting configuration consists of many environments hosted on a single infrastructure and security constraints sometimes exist between these environments. Recently, a customer consolidated many virtual machines belonging to both their Intranet and Extranet on a pair of SPARC Solaris servers interconnected through Infiniband. Virtual Machines were mapped to Solaris Zones and one security constraint was to prevent SSH connections between the Intranet and the Extranet. This case study gives us the opportunity to understand how the Oracle Solaris Network Virtualization Technology - a.k.a. Project Crossbow - can be used to control outbound traffic from Solaris Zones.

30 Aug 2012 Creating an Active/Active IPMP for Solaris 11 [27416]
Procedure Explains Network Auto Magic Service

User 20121221 blogs on how to create an active/active ipmp configuration with Solaris 11, in which automated network configuration is managed by a Solaris service called "nwam" or "Network Auto Magic". The nawm service is turned on by default, the post explains, and must be disabled before you make changes to the settings for static IP addresses. One must also employ the "default" physical networking service and be aware that this disables the ipv6 on the interfaces, which persists across reboots. The post notes that the ipadm command is the preferred tool to manage the configuration of the interfaces.

12 Dec 2011 Integration of LDoms Networking with Networking Enhancements in Solaris 11 [25047]
Focus on Behavior of LDoms Virtual in a Solaris 11 Service Domain

The network stack for Oracle Solaris 11 has been substantially re-architected in an effort known as Project Crossbow, a main goal of which is to virtualize the hard NICs into Virtual NICs (VNICs) to provide more effective sharing of networking resources. Raghuram Kothakota blogs on how LDoms networking is integrated with all the networking enhancements in S11, mainly with project Crossbow. His post is a high-level view of how LDoms virtual switch in an S11 service domain and LDoms virtual network device in an S11 Guest domain.

02 Nov 2011 Solaris 11 OS: What's Under the Hood [24855]
Come to the Launch Party on November 9, 2011

In an eloquent post, Constantin Gonzalez both introduces the new and compelling features of Solaris 11 and issues an invitation to the launch on November 9. Those new features that Gonzalez writes about include a new package manager, boot environments, and an automated installer. The migration issues of the past can, with Solaris 11, remain in the past, as one can now use Solaris 10 Containers to import Solaris 10 installations into Solaris 11 as a branded zone: the essence of management simplicity. And, with Project Crossbow, Gonzalez continues, Solaris 11 allows users to enjoy limitless network virtualization.

12 Sep 2011 With Project Crossbow, Creating an IPMP Group on Solaris 11 Is Simple [24548]
imadm Makes It all Happen Without the Old Headaches

Among the many useful networking features available in Project Crossbow is the capability to create IP multipath groups with a single new command -- ipadm -- that eliminates the fuss and bother that was once involved in setting up IPMP. Blogger unixben alerts users to this feature in his blog, where he adds the comment that, if you felt there was no compelling reason to upgrade to Solaris 11, Project Crossbow changes all that.
