Prerequisites

Controller

To deploy the DSE Controller, you need to prepare the following:

x64 host – a bare metal host or a virtual machine
8 CPU cores, 8 GB RAM, 80 GB storage, if local file system is used for DSE storage
Linux OS: Ubuntu 22.04 LTS, Debian 12, RHEL 9.4, Rocky Linux 9.4, CentOS Stream 9

Use this option if you plan to use AresONE hardware to emulate RoCEv2 NICs:

AresONE-S (400GE) and AresONE-M (800GE) hardware models are supported
To use more than one AresONE hardware unit in a trial, you need to connect them with sync cables or synchronize via Metronome Timing System.

Use this option if you plan to use x86 servers with RDMA NICs to run Data Flow Emulation (DFE). Server requirements:

x86-64 host with 1 to 4 RDMA NICs connected via PCIe Gen5
Recommended 16 CPU cores, 32 GB RAM (preliminary information)
RDMA RoCEv2 NICs: NVIDIA Connect-X 5/6/7, Broadcom Thor/Thor2. Other RoCEv2 NICs may work, but were not tested.
Linux OS: Ubuntu 22.04 LTS, Debian 12, RHEL 9.4, Rocky Linux 9.4, CentOS Stream 9
It is critical to have high precision time synchronization between the DFE hosts for accurate measurements. It is recommended to use PTP for this purpose.
On RHEL-based systems – install EPEL Repo:
```
sudo dnf install -y epel-release
```
