       - [eris-server](https://codeberg.org/eris/eris-go). [ERIS](https://eris.codeberg.page/) is an encoding for immutable storage and this server provides block exchange as well as content decoding over HTTP and through a FUSE file-system. Available as [services.eris-server](#opt-services.eris-server.enable).

       - hardware/infiniband.nix adds infiniband subnet manager support using an [opensm](https://github.com/linux-rdma/opensm) systemd-template service, instantiated on card guids. The module also adds kernel modules and cli tooling to help administrators debug and measure performance. Available as [hardware.infiniband.enable](#opt-hardware.infiniband.enable).
