Conclusion

Quantifying the Benefits of Consolidating Older HP-UX Environments to HP Integrity i4 Servers

Detailed analyses of costs and benefits associated with consolidating older HP-UX environments to HP's new Integrity Systems Featuring the Intel Itanium 9500 Series Processor. (December 2012)

In November 2012 HP® announced five new servers based on the Intel® Itanium® Processor 9500 series (formerly known as "Poulson"). These new servers include the two-socket, 2U Integrity® rx2800 i4 rack mount server; three new Integrity blade servers (BL860c i4, BL870c i4, and BL890c i4); and the new Superdome 2 with CB900s i4 blades. Some of the key benefits these new i4 servers have compared to HP's Integrity i2 servers include faster performance, reduced energy use, expanded memory support, and improved RAS (Reliability, Availability, and Serviceability). Two key features contributing to the performance gains include doubling the number of processor cores from four to eight and increasing the processor's speed from 1.73GHz to 2.53GHz. Energy savings come from lower power requirements for the i4 chips (170 watts vs. 185 watts) and support for low voltage memory (1.35V vs. 1.5V). Improvements to multiple technologies help improve Integrity i4 servers' RAS. One notable improvement is the added support for electrically-isolated hard partitions (nPars) on Integrity i4 blades, a feature previously only available in Superdome 2 systems.

Four different consolidation scenarios were analyzed in detail from a financial perspective. The analyses are based on current pricing for new Integrity i4 servers with support as well as Support Plus contracts for out of warranty servers. The analyses also use customer-reported data about the operational characteristics of the servers.

The findings show that consolidations using Integrity i4 servers running HP-UX 11i v3 can pay for themselves relatively quickly. Three consolidation scenarios using Integrity i4 blades were analyzed: an 8:2 consolidation of HP 9000 rp4440-8 application servers, a 4:2 consolidation of clustered rx8640 database servers, and a 10:2 consolidation of BL870c web servers. These consolidations broke even after 3 months, 7 months, and 10 months respectively. The three-year cumulative savings were $822,000, $1.3 million, and $377,000 respectively. The final scenario involved consolidating four Superdome 2-32s systems with Itanium 9350 i2 processors into two new Superdome 2-32s systems with Itanium 9560 i4 processors. This enterprise-class consolidation pays for itself after 1.8 years and generates cumulative savings of $2.1 million after three years.

Server consolidation remains a top priority for many IT Managers. Companies running HP-UX environment could benefit greatly by consolidating older systems into Integrity i4 servers. The consolidations pay for themselves quickly and have the added benefit of improving availability, reducing energy use, saving floor/rack space, and enabling future expansion. After the consolidations pay for themselves, additional savings can be put towards other IT projects.
