DM-Clone Target Added To Linux 5.4 For Efficient Remote Replication Of A Block Device

Added to the device mapper (DM) code with the Linux 5.4 kernel is an interesting addition that benefits those wanting to carry out some interesting use-cases around remote replication of block devices. As explained in the original patch proposal for dm-clone, "dm-clone produces a one-to-one copy of an existing, read-only device (origin) into a writable device (clone): It presents a virtual block device which makes all data appear immediately, and redirects reads and writes accordingly. The main use case of dm-clone is to clone a potentially remote, high-latency, read-only, archival-type block device into a writable, fast, primary-type device for fast, low-latency I/O. The cloned device is visible/mountable immediately and the copy of the origin device to the clone device happens in the background, in parallel with user I/O." Read more

  • Powering the hybrid cloud on next-generation hardware: Red Hat Enterprise Linux on IBM System Z and LinuxONE

    For more than five years we have been driving our technology strategy around the idea that the future of enterprise IT does not reside solely in an enterprise datacenter or in the public cloud. Instead the next wave of computing is built on a blend of these technologies and infrastructure: in short, the future is hybrid. The value of hybrid clouds comes from the choice it delivers, pairing the control of the corporate datacenter alongside the scale and flexibility of public clouds. We strongly feel, however, that the most valuable hybrid clouds are those that offer not only a choice of deployment type and location, but also a choice of the underlying architecture and the capacity to run on multiple public clouds. [....] With RHEL available on Z15 and LinuxONE III, this helps pave the way for the rest of Red Hat’s hybrid cloud portfolio, including Red Hat OpenShift, to emerge on IBM enterprise platforms. We’re pleased to continue our work with IBM in bringing the world’s leading enterprise Linux platform to their next-generation systems.
