Amazon’s EC2 (Elastic Compute Cloud), for example, is a __Cloud Computing environment (as the name implies) built using Xen__. Alternatively, __Google bases its Cloud environment almost entirely upon physical hardware__. Providers who create Cloud-based environments for public consumption, like Amazon’s EC2, will do so using virtualization due to its '''low cost, flexibility, and high performance'''. * '''''FS''''' * GPFS * [http://lxr.linux.no/linux kernel cross refreence] * [wiki:rock_gpfs_tuning tuning note] * [wiki:rock_pragma PRAGMA Demo] * [wiki:rock_gpfs_note disscussion] * Lustre * [wiki:3D_Lustre Lustre Storage Cluster for 3D Fly platform ] * [wiki:rock_lustre Lustre error] * umount 順序: clients, MDT, OSTs. * lustre_rmmod * 測試 Lustre 跨 Site,mgt、ost和Client可正常運作,測試 Lustre Arch for VM Images in Two Site 1.
