It's definitely smaller. It's somewhat less expensive (though I'm not sure how far below $220 you're going to get, once you add a power supply, I/O conditioning, etc), it takes somewhat less power (3W vs. 26W).
For the small differences in cost, size, and power, you end up with a full PC with gigabit network, 1.6GHz dual-core CPU, reasonable 3D graphics, excellent latency numbers (maybe 8000 or so IIRC), and a PCI slot. Of course there's always a bit of pride to be taken in doing more with less, I'm not sure there's really a great payoff here. - Steve ------------------------------------------------------------------------------ Return on Information: Google Enterprise Search pays you back Get the facts. http://p.sf.net/sfu/google-dev2dev _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
