LLNL' Sequoia has ZFS striped across three 8+2 hardware RADI6 arrays using 3TB drives. Lustre is then layered atop those. So here ZFS sits atop 72TB raw. It is not scaling to 55PB. Something worth noting in this "if they use it so should you" context is that US gov't computer labs tend to live on the bleeding edge, and have the budget, resources, and personnel on staff to fix anything, including rewriting Lustre and ZFS to fit their needs. The name Donald Becker may be familiar to many here. He wrote a good number of the Linux ethernet device drivers while building Beowulf clusters at NASA. They bought a bunch of hardware, no Linux drivers existed, so he wrote them to enable their hardware. Eventually they made it into mainline. The moral of this story should be obvious. -- Stan -- To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
