Exalogic Virtual Tea Break Snippets – Creating Accounts

Once we have created our Users and Networks we will want to
enable the Virtual Data Centre (vDC) for access by the Cloud
Users. To facilitate this we will need to create Accounts within
the vDC / Cloud and allocate the users to these accounts. Once a
Cloud User has been allocated to an account they will be able to
access that account and hence create / manage Virtual Servers
within that account / Pool.

To create an Account within a vDC / Pool you will
need to be logged into Enterprise Manager Ops Centre (EMOC) with
the appropriate Role, and this is generally done using you Cloud
Administrator, then simply navigate to the vDC Management
Accordion, vDC, your Cloud and finally Accounts.

Configure IPoIB on Solaris 10 branded zone

Compute nodes in Exalogic communicate with each other and mount their shares from the ZFS storage appliance over the bond0 interface. Bond0 is a highly available network interface over the InfiniBand fabric using a portability layer called IPoIB that allows compute nodes and the storage appliance to communicate using TCP/IP protocol over InfiniBand.

In previous entry, we have created a Solaris 10 branded zone, obviously we would also like the branded zone to be able to mount shares from the ZFS storage appliance over IPoIB.

In this entry, I’ll show you the steps.

Create Solaris 10 Branded Zone on Exalogic

One of the reasons that customers choose to run Solaris 11 Express on Exalogic is the capability to create container. Container is a form of Operating System Virtualization that allows multiple operating system environments to coexist on a single system. Container not only allows user to run the same version of Solaris but it is also possible to create a container, also known as branded zone, to run previous Solaris version, such as Solaris 10. It is a very useful feature that enable customer to continue running applications that only certified on older OS version.

In this entry, I will show you the steps to create a Solaris 10 branded zone on Exalogic.
