Since today's e-business systems require both scaling up and scaling out, PC servers may satisfy one dimension but not another. Moreover, Intel chairman Andrew Grove's suggestion that cost drives server selection is, in Gartner's view, myopic.
Grove's comment bears on the competitive
If Intel's 64-bit architecture, IA-64, (including the availability of Windows 2000 Data Center Edition) had appeared concurrently with Sun's high-end road map, Intel may have been able to secure the high end. Intel might have driven more downstream server sales by giving customers the secure knowledge that they had a smooth upgrade transition through all Intel processor families.
As it is, IA-64 will make its initial appearance only late in 2000 and will likely require a test and validation period of 18 to 24 months to establish its credibility against enterprises' greater experience with RISC. IA-64 is a disruptive technology--its technology progenitor does not predict future performance. Disruptive technologies take longer for market acceptance and must prove dramatic benefits, or enterprises will choose the path of least resistance (higher IA-32 scaling and RISC systems).
RISC system vendors have well-planned road maps and continue to add functions and capacity-on-demand upgrades, which tend to lock in customers. It will take more than a pure price play in critical e-business applications to persuade enterprises to abandon a known system product with an excellent track record.
