They communicate over a gigabit network. I would like to create a fault-tolerant array from these machines and their storage, that would match RAID6 in overhead and fault resilience. That is, it should provide 8 TB of usable space and tolerate a 2-member failure without data loss. Does anyone know if any of the current distributed filesystems will meet th= ese requirements? Working/stable/non-experimental level code is preferred. The simple and obvious solution is mdadm over AoE/iSCSI, but maybe there is something else built with network awareness from ground up, that would be a better choice? --=20 With respect, Roman --Sig_/dFrV2V0C60Mn4zw8vCu3.3J Content-Type: application/pgp-signature; name=signature.asc Content-Disposition: attachment; filename=signature.asc -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.11 (GNU/Linux) iEYEARECAAYFAk2S170ACgkQTLKSvz+PZwgGsQCbB/Q/h604SWs9juHmKA9xFgRw e9IAn1WC0wQnfflJDsu5KlF6a1xuhiau =eI6b -----END PGP SIGNATURE----- --Sig_/dFrV2V0C60Mn4zw8vCu3.3J--
