Total Cost of Upgrade Study for the Product Lifecycle Management Application Market: Sun SPARC Servers to HP ProLiant Servers

Detailed analyses of costs and benefits associated with upgrading out-of-warranty Sun servers being used for PLM applications to HP ProLiant servers. (November 2009)

Product Lifecycle Management (PLM) software helps shorten the amount of time needed to design new products and bring them to market. Many companies throughout the world rely on PLM software as a key component of their IT infrastructure. In 2008, CIMdata estimated the worldwide PLM market was $16.7 billion for software and related services. Sun and HP are two of the top server manufacturers in this market. There is an installed base of PLM customers that run their applications on older Sun SPARC servers. This paper provides in depth analyses into whether or not these companies should consider upgrading their older Sun SPARC servers to new HP ProLiant servers.

Some of the most widely used PLM applications include Teamcenter from Siemens PLM, Windchill and Pro/Engineer from PTC, and ENOVIA from Dassault Systèmes. These applications all utilize multi-tier configurations. Although there are some differences by vendor, a PLM installation typically has a database layer, application layer, and a presentation layer. Each layer would run on its own separate server.

TechWise Research conducted robust TCU analyses on three different upgrade scenarios. These analyses combine readily available data about system pricing with actual customer data about system manageability and availability. A total of 86 IT professionals from US-based companies participated in a web survey that provided the customer data. This web survey targeted System Administrators and other IT professionals who are using Sun SPARC or HP ProLiant servers in a PLM environment. The survey collected detailed operational data on these servers.

HP ProLiant servers have several potential benefits to companies that are running PLM applications on older Sun SPARC servers. First, HP’s newer ProLiant servers that are based on the Intel’s Nehalem chip offer very competitive price/performance ratios. Due to the relatively low price of the ProLiant servers compared to the original Sun hardware, savings from the out-of-warranty support costs for the older Sun servers pay a considerable fraction of the cost of the new servers. Second, based on customer data, the HP ProLiant servers require less time to manage than Sun SPARC servers. Third, again based on customer data, HP ProLiant environments have less unplanned downtime than Sun SPARC environments.

Thanks to these benefits, all three upgrade scenarios quickly pay for themselves. The entry-level scenario involves upgrading a three-tier Sun environment consisting of a Sun v490, Sun v215, and Sun v125 to a three-tier HP environment consisting of a ProLiant DL380 and two ProLiant DL180s. The list price of the three new HP servers is $22,900. The upgrade pays for itself in just 6 months thanks to the improved availability and manageability of the ProLiant servers compared to the Sun servers. After three years this upgrade would result in cumulative savings of $112,000.

In the midrange scenario, a four-tier Sun environment consisting of a Sun E2900, Sun v215, and two Sun v125s is upgraded to a four-tier HP environment consisting of a ProLiant DL585 and three ProLiant DL180s. The list price of the three new HP servers is $40,300. The upgrade pays for itself in less than 6 months, resulting in cumulative savings of $210,000 over three years.

Finally, in the high-end scenario, a four-tier Sun environment consisting of a Sun E6900, Sun v490, and two Sun v215s is upgraded to a three-tier HP environment consisting of a ProLiant DL785 and two ProLiant DL180s. The list price of the three new HP servers is $59,300. The upgrade pays for itself in just 6 months, and results in cumulative savings of $261,000 over three years.

Most IT managers are always looking for ways to get better returns from their IT infrastructure. Companies that are running PLM applications on older Sun servers may be able to accomplish this goal by upgrading to HP ProLiant servers. As long as the number of users stays the same, the PLM vendors typically do not charge any fees to switch from one operating system to another. Upgrading to HP ProLiant servers could save money due to Sun’s out-of-warranty support costs as well as differences in ongoing server management and downtime costs. Three scenarios were analyzed in detail. In all three scenarios, it is assumed that the database server is running Oracle database. Furthermore, all of the HP ProLiant servers are using Intel’s new Nehalem processor. All three scenarios paid for themselves in less than a year, making this upgrade a compelling option for many companies.
