Micromuse (Nasdaq: MUSE), the leading provider of ultra-scalable, realtime business and service assurance software, today announced that its Netcool® solutions’ support for managing the Sun Solaris™ 10 Operating System (OS) will be extended to the Sun x64 platform, expanding its existing support for the Solaris 10 OS on SPARC® processor-based systems.

The added support allows Sun and Micromuse to collaboratively deliver solutions which leverage the unique features of the Solaris 10 OS and Micromuse’s end-to-end service management. Customers will also realize the benefits of this collaboration through solutions such as consolidation, grid computing and business service management. Micromuse will include support for the Solaris 10 OS on x64 platforms with its System Service Monitor and Application Service Monitor modules, in addition to the support already offered for the Solaris 10 OS on SPARC-based systems.

“The availability of Micromuse service management capabilities for Solaris 10 OS customers will help them harness the significant increases in capacity and performance provided by the Solaris 10 OS-powered infrastructure and further optimize their IT environment,” said Stephen Borcich, Vice President of Partner Marketing, Sun Microsystems. “Micromuse will help our customers to increase the price and performance benefits they derive from their Sun investment.”

“We are thrilled to continue growing our relationship with Sun by enabling broad support for the Solaris 10 OS, which is a vital operating system for many of our joint customers, as well as a key development platform for Micromuse,” said Craig Farrell, Micromuse CTO. “The integration of the Solaris 10 OS and Netcool solutions provides customers the ability to easily consolidate management consoles and view the status of their infrastructure end-to-end, increasing the business value of their IT deployments.”

Sun Microsystems’ Professional Services group is reselling, integrating and supporting Micromuse’s Netcool solutions. Micromuse is also member of several high-profile Sun software initiatives, including Micromuse Netcool’s integration with the Sunâ„¢ Management Center software; the SunToneâ„¢ Certification & Branding Program for telecommunications providers; and the Sun Developer ConnectionSM program. In addition, Micromuse’s Netcool Software Suite is a core component of the Sun Javaâ„¢ System Messaging Internet Data Center Reference Architecture launched in May 2002 — the first solution that can support up to one million users with no single point of failure. ISP and Enterprise customers are able to get to market with their Internet messaging services faster and with greater confidence with this architecture driven solution that will fit their workload and performance needs now, and as their business grows.
