@Rink - Eclipse2/Sonos - Server
When it comes to Server, power will be a big topic, no
question, but we have to ask, where the big cuts could be
seen. When we see Server-CPUs with 95 or 130W, you could
save tons of Watt, if you go down to 45/65W. Thats easily a
30-50W per CPU unit. Imagine 1000 CPUs and you are at 50KW.
When it comes to harddisks, common drives are in the 10-15W
range under load and 2-3W idle. Drives don't run 100% of time,
so it should be an avarage of probably 5-10W. Even you could
save 4-8W a 1000 drives save 4-8KW, thats much less compared
to the CPU-side and it should be clear, that this function
will probably a possible SSD (NAND) task. When it comes to
DRAM itself, we have to look at different modules. DDR2
modules don't consume to much power. I have to look at some
datasheets, but when I remember correctly 1GB are in the 5-7W
range - very roughly. FBDIMM takes much more, we are easily
in the 15W range here. The problem here is, what you want
to replace. You could replace some DRAM to save power, no
question, but DRAM is extremly fast (thats the argument for
using DRAM ;-) ), so its at least for me unpossible to reach
that speed with some type of NOR. We don't speak about
hundrets of MB/s, we speak about thousands of MB/s or even
tens of thousands/s. This would mean, that SONOS/Eclipse2
have to work 100 times faster than current versions. Even if
we are bullish, thats unreachable. Even if 10x times could
be reached, which would be amazing, that speed would be low
compared to DRAM. So, where is the application?
