Price-performance is everything in data warehousing (DW), and it’s become the leading battleground for competitive differentiation.
As I noted in a blog post last month, the price of a fully configured DW appliance solution has dropped by an order of magnitude over the past 2-3 years, and it’s likely to continue declining. In 2010, many DW vendors will lower the price of their basic appliance products to less than $20,000 per usable terabyte (TB), which constitutes the new industry threshold pioneered by Oracle, Netezza, and other leading DW vendors.
But that’s just a metric of price, not price-performance. Ideally, each DW appliance vendor should be able to provide you with a metric that tells you exactly how much performance “bang” you’re getting for all those bucks. In a perfect world, all vendors would use the same price-performance metric and you would be able to compare their solutions side by side.
But, as I noted a year ago in another blog post, truly comparable cross-vendor DW benchmarks have never existed and are unlikely to emerge in today’s intensively competitive arena. No two DW vendors provide performance numbers that are based on the same configurations, workloads, and benchmark metrics. And considering how sensitive these performance claims are to so many variables in the vendors’ solutions and in customers’ production environments, it can be quite difficult to verify every vendor performance claim in your specific environment.
