It appears this is more of a simulator at the moment and an experimental framework. Is there any current support for the MM-5425CN series NAND flash cards in FreeBSD? These seem like they'd be excellent for a separate ZIL in a ZFS raidz config if installed in pairs for mirroring... Here's the pciconf probe of the device in question: none3@pci0:6:2:0: class=0x058000 card=0x00000000 chip=0x54251332 rev=0x06 hdr=0x00 vendor = 'Micro Memory' device = 'MM-5425CN PCI 64/66 Memory Module with Battery Backup' class = memory Also, does anyone have any direct experience with ZFS + NFS? It seems like there's some disagreement on whether or not this taxes the host machine to the point that performance drops off significantly. -- Erich M.
