[-- Attachment #1 --] Hi, We need to set up a ZFS pool with redundance. The main goal is high availability - uptime. I can see a few of paths to follow. 1. HAST + ZFS 2. Some sort of shared storage, two machines sharing a JBOD box. 3. ZFS replication (zfs snapshot + zfs send | ssh | zfs receive) 4. using something else than ZFS, even a different OS if required. My main concern with HAST+ZFS is performance. Google offer some insights here, I find mainly unsolved problems. Please share any success stories or other experiences. Shared storage still has a single point of failure, the JBOD box. Apart from that, is there even any support for the kind of storage PCI cards that support dual head for a storage box? I cannot find any. We are running with ZFS replication today, but it is just too slow for the amount of data. We prefer to keep ZFS as we already have a rather big (~30 TB) pool and also tools, scripts, backup all is using ZFS, but if there is no solution using ZFS, we're open to alternatives. Nexenta springs to mind, but I believe it is using shared storage for redundance, so it does have single points of failure? Any other suggestions? Please share your experience. :) Palle [-- Attachment #2 --] -----BEGIN PGP SIGNATURE----- Comment: GPGTools - http://gpgtools.org iQEcBAEBCAAGBQJXOZwmAAoJEDQn0sf36Uls3OsIAKelrK6+NG5LtCsTOOa0yy+2 5JCUsdVm+77IOGC2tl8AVTYGK2SODSiW1WZZiCNB4pfRFacKjNqBGSm3GDUizh0k CvALLacegxvSqsKzu6TMUifQa0UPZayoswLMKbfj6zavKy+kxFyHTiursS7X5XgZ HOng44oq+p1S+AtvXvRTDegSMIIAzYFppznN+vNuyv1qjOBoPJaf4gp9g2PCfOi0 S6iz/J5f1x2Dtg3m/FAky7nn2Kj6BgajyLaLtOi1lhoG91PqKFngneFidjtLS0Sr vmaIO/HGQpaPi2RaEpAODoQzUbfF7fdp8IVRYlS1FuqzdfIckF/MzpyKJV6R7E0= =RLQy -----END PGP SIGNATURE-----
