Ok, had a bit of a look around, What about this setup. Two boxes with all the hard drives in them. And all drives iSCSI Targets. A third Box puts all of the Drives into a mirrored RAIDz setup (one box mirroring the other, each has a RAIDz zfs zpool). This setup wil be shared via samba out. Doe

[zfs-discuss] Single SAN Lun presented to 4 Hosts

2007-08-24 Thread Matt B
Is it a supported configuration to have a single LUN presented to 4 different Sun servers over a fiber channel network and then mounting that LUN on each host as the same ZFS filesystem? We need any of the 4 servers to be able to write data to this shared FC disk. We are not using NFS as we do

That is what I was afraid of. In regards to QFS and NFS, isnt QFS something that must be purchased? I looked on the SUN website and it appears to be a little pricey. NFS is free, but is there a way to use NFS without traversing the network? We already have our SAN presenting this disk to each o

Cant use the network because these 4 hosts are database servers that will be dumping close to a Terabyte every night. If we put that over the network all the other servers would be starved This message posted from opensolaris.org ___ zfs-discuss mai

hi, Few questions, I seem to remember in WAN environments IPsec can have a reasonably large performance impact, how large is this performance impact? and is there soe way to mitigate it? The problem is we could be needing to use all a gigbit links bandwidth (possibly more). is IPsec AH slightly
