This sounds interesting as I have been thinking something similar but never implemented it because all the eggs would be in the same basket. If you don't mind me asking for more information: Since you use Mapped Raw LUNs don't you lose HA/fault tolerance on the storage servers as they cannot be moved to another host? Do you mirror LUNs from storage servers on different physical servers for the guests to achieve fault tolerance? Or would you consider this kind of setup "good enough" for production without making it too complex like above question? > > This is precisely the thing I'm interested in. How do you do that?

How to accomplish ESXi 4 raw device mapping with SATA at least: http://www.vm-help.com/forum/viewtopic.php?f=14&t=1025 It does work as long as your hardware supports "VT", which would be any modern computer. - Ville > > What's the trick that I'm missing? > > _______________________________________________ > zfs-discuss mailing list > zfs-discuss@opensolaris.org > http://mail.opensolaris.org/mailman/listinfo/zfs-discuss _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
