Mats, dd simultaneously in both dom0 = 170 MB/sI take it you mean "two parallel 'dd' commands at the same time"? That would still write to the same portion of disk (unless you specifically choose different partitions?) it's different partitions - one dedicated partition for each domU. The partition are created as "virtual" block devices with the dell storage box manager. I take it this means two different DomU doing "dd"? Is that 34 MB/s "total" (i.e. 17MB/s per domain) or per domain (68 MB/s total)?dd simultaneously in two domU = 34 MB/s sorry, good you asked: it's the total, i.e. 17MB/s per domain! I guess you are getting the picture now as to my feelings... ;-) Kind regards, Andrej _______________________________________________ Xen-users mailing list Xen-users@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-users |
