[zfs-discuss] random or sequantial writes and Jbot redundany
Hi all; Optimizing the array controller to random or sequantial controller depends on your read/write ratio. ZFS have the ability to combine random writes to a sequantial write. However eads stilll be random. And for Jbod redundany I have a few comments 1) You can do three way mirror on very critical volumes. Using ZFS saves a lot of money, cheepest 2540 controllers still will set you back 10k $''s so three way mirror will be still economical 2) You may write scripts to add spares after a failure, this may not be very flexible how ever will do what you want My 2 cents <http://www.sun.com/> http://www.sun.com/emrkt/sigs/6g_top.gif Mertol Ozyoney Storage Practice - Sales Manager Sun Microsystems, TR Istanbul TR Phone +902123352200 Mobile +905339310752 Fax +902123352222 Email <mailto:Ayca.Yalcin at Sun.COM> mertol.ozyoney at Sun.COM -------------- next part -------------- An HTML attachment was scrubbed...
