Probably. That's the sort of thing I would do if I could pull via rsync. If I could only push via rsync things might be different. >> A lot of people posting here appear to like chassis from SuperMicro. >> You might also want to consider an external enclosure; I've had good >> perf with a 4 disk Proavio Enhance 4-ML unit hanging off an LSI SAS >> controller.

The HCL is a good place to start: http://www.sun.com/bigadmin/hcl Note that both the Solaris 10 and Solaris Express versions are useful to you. You'll also find the Device Driver Detection Tool on the osol200805 livecd, run that (java app) on your system and it'll tell you what's got a driver and what doesn't. Apart from the HCL and DDDT, I strongly recommend Masa Murayama's drivers - http://homepage2.nifty.com/mrym3/taiyodo/eng/index.html James C.
