Open HA Cluster 2009.06 Is Now Available

Open HA Cluster 2009.06 is the latest open-source binary based on Sun Cluster 3.2, now running on OpenSolaris 2009.06. This release includes some new features, only in Open HA Cluster, that can reduce the amount of hardware you need in your cluster:

• The use of virtual NICS (VNICs) to route private-network traffic over the public network, eliminating the need for private interconnect cabling.
• COMSTAR iSCSI support to enable all cluster nodes to access locally attached storage.

There's plenty more to learn about, so go take a look!

Support for RAC on Zones

Support for RAC on zones has just today been announced for Solaris Cluster Express (SCX) 9/08. You can learn more about this new support by going to the Solaris Cluster Express area on the OpenSolaris web site.

The RAC on zones feature introduces some new, and changes some very fundamental, Sun Cluster concepts, and sets in motion some very big changes in the way you might have thought about Sun Cluster.

The clzonecluster man page (PDF) tells you more about the command that you use to manage zone clusters.

Download and configure Solaris Cluster Express, and take a test drive. Then, let us know what you think.

Sun Cluster High Availability (HA) Data Service for MySQL

By now, you might have heard that Sun is acquiring MySQL. What you might not have heard is that Sun Cluster provides a data service for MySQL and has provided one since the release of Sun Cluster 3.0.

The Sun Cluster HA data service for MySQL provides a mechanism for the orderly startup and shutdown of, fault monitoring of, and automatic failover of a MySQL database.

The Sun Cluster HA data service for MySQL, which is not scalable, is now supported in Sun Cluster 3.1 and in Sun Cluster 3.2 on the Solaris 8, Solaris 9, and Solaris 10 OS on the SPARC platform and on the Solaris 9 and Solaris 10 OS on the x64 platform. You can use the Sun Cluster HA data service with MySQL database versions 3.23.54a through 4.0.23, 4.1.6 through 4.1.22, and 5.0.15 through 5.0.45. The Sun Cluster HA data service for MySQL is supported in failover zones by using the container agent in Sun Cluster 3.1 and in failover nodes using the container agent and zone nodes in Sun Cluster 3.2.

The Sun Cluster HA data service for MySQL also includes support for the Service Management Facility (SMF) as well as a Zettabyte File System (ZFS) that's used as a local highly available filesystem. What's even better, the Sun Cluster HA data service for MySQL has recently been open sourced.

Jenny Chen's blog Installation and Configuration Sun Cluster Data Service For MySQL provides a detailed, hands-on example of how to install and configure this data service in a two-node cluster.

If you like, feel free to take a look at a reprint of Sun's Sun Cluster Data Service for MySQL Guide for Solaris OS.

Get the Next Version of Sun Cluster 3.2 Release Notes at the Sun Cluster Wiki

First, we put Sun Cluster patch information at your fingertips on the Sun Cluster Wiki. Then we moved Sun Cluster Release Notes Supplements to the Sun Cluster Wiki. Soon, you'll be able to get release notes for upcoming update releases of Sun Cluster 3.2 and Sun Cluster Geographic Edition 3.2 software at the Sun Cluster Wiki as well (rather than from docs.sun.com). Keep your eyes peeled for more exciting news about this thrilling, new development!

Solaris Cluster Support in LDOM I/O Domains

Starting with Solaris Cluster 3.2, Solaris Cluster is now supported in Logical Domains (LDoms) I/O domains. I/O domains are domains that include physical devices and are not dependent on other domains (such as a service domain) for their operation.

New Solaris Cluster Support for x86 Hardware

Sun has some big news today from the Solaris Cluster team.

We're announcing the first support for Solaris Cluster on non-Sun servers. For those of you who haven't been paying attention, Solaris Cluster is the high availability platform for the Solaris OS.

Companies running Solaris 10 on non-Sun x86 hardware now have the opportunity to leverage Solaris Cluster to help automatically increase their overall system availability. Information about supported configurations, as well as the FAQ's are available Solaris Cluster Open Hardware Program.

The ensures seamless interoperability of third party server products with Solaris Cluster. What's really cool is that both Sun and the third party server vendors test configurations and both also respond to support calls.

Sun and Hewlett-Packard customers now have the option of running Solaris Cluster on Hewlett-Packard Proliant DL 385 G2 and Proliant DL 585 G2 servers. For a technical explanation of what Sun engineers Vishwanth Mantha and Matt Ostberg learned during the initial implementation of Solaris Cluster on Hewlett-Packard servers check out Solaris and Solaris Cluster on HP ProLiant Servers. The Solaris Cluster Oasis is the place to go to read more technical blog entries and case studies from the Cluster engineering team. Recent posts have covered the quorum component, Solaris Cluster Express and Solaris Cluster support in LDoms I/O domains.
