MCA Tips Feed. You can use Oracle Solaris Cluster to create high-availability clusters of logical domains in two ways: by simply configuring the logical domains as a cluster, or by setting up Oracle Solaris Cluster inside the control domain of Oracle VM Server for SPARC. The second approach offers significant benefits, as described here.

MCA Tips Feed. Apache Hadoop helps you process large amounts of data on multiple computers that are clustered together. Oracle Solaris zones are easy to clone and manage as a cluster. Oracle Solaris 11 has great network virtualization capabilities. Orgad walks you through all the steps required to combine these three technologies into an easy to manage big data cluster.

MCA Tips Feed. More about the dm-nfs kernel module, courtesy of Lenz Grimmer. If you want to work with block-based shared storage devices such as ocfs2, but you don't have iSCSI or SAN storage, you can use NFS, instead. Just create an NFS file that will contain the block-based shared storage device. In fact, you can create several shared storage devices that way. And use the "dm nfs" utility to create a device map. Lenz Grimmer expands on Wim's original blog.

MCA Tips Feed. We liked this blog so much when Jeff Victor first posted it, that we turned it into a bonafide OTN tech article. You might recognize it. It's about ZOSS: zones on shared storage. Why? When you configure a zone on shared storage, you can quickly clone it on any server that uses that storage. Jeff explains how.
