So NFS wins over iscsi, as I see. Is it safe to run postgres and mysql data over nfs? I know, windows is a different story, sqlserver must run its data on iscsi or real hd... ---------------------------------------------------------------------------------- Da: Dan Swartzendruber A: Discussion list for OpenIndiana Data: 10 giugno 2011 22.05.22 CEST Oggetto: Re: [OpenIndiana-discuss] Backups and snapshots Magnus wrote: On 6/10/11 3:56 PM, Gabriele Bulfon wrote: Thanx for the reply ;) I read somewhere that NFS is much slower than having an iscsi device. Somewherelse they said the contrary.... I think a lot of it can do with the clients being used. But in my experience here, zfs backed iscsi targets are on-par with NFS on read performance, but lag badly on write performance. NFS clients perform pretty well in both read &write operations. ESX seems to like its vmdk's on NFS more than iSCSI here. Agreed. I have seen ESXi get finicky if it thinks the iSCSI target is offline. One gotcha: it depends if the iSCSI storage is a file or a zvol. Performance of the former seemed to be about that of NFS - performance of the latter sucked (I was seeing about a 50% degradation...) _______________________________________________ OpenIndiana-discuss mailing list [email protected] http://openindiana.org/mailman/listinfo/openindiana-discuss
