Avahi is a DNS service discovery system, and a mDNS responder (announcer). It is not a storage techonology, that's for sure. I think your question should be rephrased into: Can I use Avahi to announce and/or browse SANs and other storage devices? Answer: you can use Avahi (and whatever other implementation of DNS-DS) to announce and/or browse any service that is covered in the DNS SRV (RFC 2782) Service Types list. Please have a look at http://www.dns-sd.org/ServiceTypes.html . Of course, you can add any other services to that list. Also, remember what's the purpose of DNS Service Discovery. Your computer shouts "Is anybody out there??", and gizmos in the network reply "Hi there, I'm 10.3.4.5, and I'm a HTTP and FTP server". This would make sense, but there is a problem: the iSCSI specifications include a method for target discovery, as noted in RFC 3720, appendix D (http://www.ietf.org/rfc/rfc3720.txt). I'm going to put my conservative hat and tell you "If it works, don't touch it". iSCSI has its own method to discover targets, leave it alone. However, if I put my lets-have-some-fun hat, I'd replace the entire SendTargets request mechanism with a multicast DNS service discovery system (Avahi/Bonjour/whatever). But, this could prove troublesome (as the iSCSI devices should support both the SendTargets and mDNS announcements) and somewhat incompatible (some clients/devices that only support one of SendTargets/mDNS). IMHO, replacing the iSCSI discovery method with Avahi is not a very good (and backwards-compatible) idea. However, if your storage devices offer any other methods for accesing the data (HTTP/FTP/rsync/NFS)... what are you waiting for to use Avahi to announce and discover them??! P.S.: I have read RFC3720 very, very briefly. Oh, and don't take me too seriously. - -- - ---------------------------------- Iván Sánchez Ortega <[EMAIL PROTECTED]> <[EMAIL PROTECTED]> http://acm.asoc.fi.upm.es/~mr/ ; http://acm.asoc.fi.upm.es/~ivan/ MSN:[EMAIL PROTECTED] Jabber:[EMAIL PROTECTED] ; [EMAIL PROTECTED] -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.2 (GNU/Linux) iD8DBQFD+K2H3jcQ2mg3Pc8RArnWAJ9Qef4FsNXmtqs6tU2gYvGp6E5u4wCeLv1O PYfSdimgzohpeNalnkMLMQs= =wNBg -----END PGP SIGNATURE----- _______________________________________________ avahi mailing list [email protected] http://lists.freedesktop.org/mailman/listinfo/avahi
