I'm actually very afraif of all those cards with plenty of cache and no battery backup for it. It has been proven (on certain notebook disks iirc) that even 2mb cache on disks themselves if not flushed properly on shutdown can be a disaster for the filesystem. Don't want to expirience what happens if you manage to create a 128mb large "hole" in your data. That's why you see write caching disabled everywhere by default. And write caching is what we in the mail business want the most ... 3ware has gotten the right idea recently and started offering batery backup units for their cards. I'm trying to get one to test ... Because of that (and because I already have FC infrastructure in place) I'm mostly interested in standalone disk enclosures doing their own raid with cheap sata drives and big caches with batteries. -- Jure Pečar http://jure.pecar.org/ --- Cyrus Home Page: http://asg.web.cmu.edu/cyrus Cyrus Wiki/FAQ: http://cyruswiki.andrew.cmu.edu List Archives/Info: http://asg.web.cmu.edu/cyrus/mailing-list.html
