@Wörns - Eclipse2 " If Viridents memory solution replaces DRAM it may be about an order of magnitude bigger fitting in the same thermal envelope. " As said to Rink already, Speed is the highest concern to me. Its at least impossible in my mind, that NOR could ever reach DRAM speeds, which will rise over time too. So NOR could be some type of buffer because the digits don't go away when power is cut off, but thats a NAND (SSD) solution - imho of course. BUGGI

Woerms, I guess the use for Eclipse2 in datacenter servers is that you want to have the whole Database reside in memory. Yup, you got it. That's the trend. Latency is the enemy, and latency improvements in hard drives have stopped. In an industry that is based on things improving all the time, it is clearly unacceptable. As far as the future, the competition between SSD and Virident solution (with Spansion flash) - assuming it takes off. Obvoiusly plain SSD has a lot going for it, since it is a plug in replacement. Spansion solution seems superior to me assuming that large DRAM vs. small DRAM + flash performance is similar. - The disadvantages of SSDs are that you need 2 copies of info at the same time: NAND + DRAM. The storage size is limited and expensive (2 silicon coppies). Power consumption is an issue. - In comparison, with Virident, you have only 1 copy of expensive silicon storage. Total storage (Hard drive + Virident) is nearly unlimited (Virident memory serves as traditional disk cache). Power consumption is excellent. Joe
