The release of DRBD® 9.3.1 brings with it a “streaming I/O” feature. This feature means that DRBD can allocate compound pages from the kernel as I/O buffers. When applications make large I/O requests or streaming accesses, using compound pages can improve performance because DRBD will use CPU resources more efficiently. Background on DRBD memory allocation […]

To complement a running-in-production or enterprise Kubernetes deployment involving persistent data, you will likely want an off-site […]
