Thanks Richard. I saw that announcement in a couple of other techsites during the week. This looks like a golden opportunity for Sun to lead, rather than lag, the market in a new, highly anticipated, market segment. If you look at the overall I/O throughput in Mb/Sec over the years and compare it with the advances in server memory size or SPEC-int rates over the years, the I/O throughput curve looks *almost* flat - as the delta between the other two curves continues to widen. What is even worse, is that to improve the I/O curve, especially in terms of I/O Ops/Sec (IOPS) is very, very expensive. Flash drives - or even a RAM/Flash drive combo - have the capability to dramatically change the IOPS curves for the first time in 10 years. And almost everyone I know, wants to own and deploy a flash based storage system as soon as the price/performance ratio is "reasonable". Historically RDBMS (or other transaction based systems) were limited by CPU "horsepower". This is no longer the case - now it's simply a matter of IOPS as multi-core CPUs are widely available at commodity prices. And solid state storage systems will dramatically increase transactions/Sec for any RDBMS type system with no other changes to the production platform. I can't wait for the market to reach commodity price/performance.....
