We already have an external filer. But still (or better again) discuss about using NFS vs. iSCSI in Dom0 and then map the iSCSI Blockdevices in Dom0 to DomU. Because of performance concerns. Although originally we preferred NFS because of the ease of management of the whole concept.
But 20% difference in performance restarts that discussion all over again. > The percentages vary, if you set it up correctly, a DomU NFS server will > be only ~10 percent slower than a native server. Are there any relyable comments/documents on this topic? -marc -- Gruss / Regards, Marc Grimme http://www.atix.de/ http://www.open-sharedroot.org/ _______________________________________________ rhelv5-list mailing list [email protected] https://www.redhat.com/mailman/listinfo/rhelv5-list
