Data compression with the Integrated Accelerator for zEDC

Hardware dependency: The Integrated Accelerator for zEnterprise® Data Compression (zEDC) is available on IBM Z® and LinuxONE hardware as of z15™ and LinuxONE III.

The Integrated Accelerator for zEDC replaces hardware-acceleration through zEDC Express as available for earlier hardware, see Data compression with GenWQE and zEDC Express.

The Integrated Accelerator for zEDC provides on-chip hardware-acceleration for data compression and decompression.

Red Hat Enterprise Linux 8.6 LPAR mode z/VM guest KVM guest

The prerequisites for using the Integrated Accelerator for zEDC depend on your virtualization environment.

Linux® in LPAR mode: The on-chip accelerator is always available if the hardware provides it.
Linux as a guest of KVM or z/VM®: The hypervisor must run on hardware that provides the on-chip accelerator, and it must support the z15 CPU model and provide it to the guest..
Linux container: The on-chip accelerator must be available to the Linux instance that runs the container. The requirements for the image are the same as for the user space of any Linux instance.

Tip: Read /proc/cpuinfo. If the features line includes dflt, your real or virtual hardware provides the on-chip accelerator.
