Hello list. I am evaluating options for my new upcoming storage system, where for various reasons the data will be stored on 2 x 2tb SATA disk in a mirror and has to be encrypted (a 40gb Intel SSD will be used for the system disk). Right now I am considering the options of FreeBSD with GELI+ZFS and Debian Linux with MDRAID and cryptofs. Has anyone here made any benchmarks regarding how much of a performance hit is caused by using 2 geli devices as vdevs for a ZFS mirror pool in FreeBSD (a similar configuration is described here: http://blog.experimentalworks.net/2008/03/setting-up-an-encrypted-zfs-with-freebsd/)? Some direct comparisons using bonnie++ or similar, showing the number differences of "this is read/write/IOPS on top of a ZFS mirror and this is read/write/IOPS on top of a ZFS mirror using GELI" would be nice.
I am mostly interested in benchmarks on lower end hardware, the system is an Atom 330 which is currently using Windows 2008 server with TrueCrypt in a non-raid configuration and with that setup, I am getting roughly 55mb/s reads and writes when using TrueCrypt (nonencrypted it's around 115mb/s). Thanks. - Sincerely, Dan Naumov _______________________________________________ [email protected] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to "[email protected]"
