How much is too much?

  • Article

There was a fascinating discussion on one of our internal mailing lists earlier today, towards the tail end of it, someone asked what the memory management guys would do when machines started coming with 8TB of memory.

5 minutes later came the following response:

There are already TPCC benchmarks being done with 1TB of RAM.

I bet we will run out of 8TB for giant machines sometime in 2008.5, if Moore’s Law applies to memory capacity (double once every 18 months).

Gleep!

I find the concept of a machine with more than 8G of RAM to be mind boggling.  And this guy's saying that big machines will be running with 8TB of of RAM in four years.  That's 8,000,000,000,000 bytes of RAM (give or take a couple of gigabytes).  8,000 GIGABYTES of RAM.

We truely do live in remarkable times.
