Hi, I'm not aware of any of those features in Ceph and i don't think that it will be possible in the near future. But while thinking about it, is ZFS an option for you? You could then use a lot of SATA disks and add some SAS disks for your caching. ZFS will then place the most used blocks on the SAS disks. -- Met vriendelijke groet, Wido den Hollander Hoofd Systeembeheer / CSO Telefoon Support Nederland: 0900 9633 (45 cpm) Telefoon Support België: 0900 70312 (45 cpm) Telefoon Direct: (+31) (0)20 50 60 104 Fax: +31 (0)20 50 60 111 E-mail: support@xxxxxxxxxxxx Website: http://www.pcextreme.nl Kennisbank: http://support.pcextreme.nl/ Netwerkstatus: http://nmc.pcextreme.nl On Tue, 2010-06-08 at 10:30 +0000, Tomasz Chmielewski wrote: > I'd like to build a cluster for storing large amounts of data. > > The cluster would consist of slow (cheap) storage and fast (expensive) > storage. > > I would like to migrate data from fast (expensive) storage to slow > (cheap) storage if it wasn't accessed for, say, 6 months. > > Would ceph somehow help me achieve that? > > If not, do you know anything which comes to mind? > > > -- To unsubscribe from this list: send the line "unsubscribe ceph-devel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
