SMS Gateway Hardware Requirements

This guide outlines the hardware requirements of the Ozeki software. You will first find the basic definitions and the recommended hardware configurations. You will find information about the supported operating systems, and the recommended hardware setup for you system.

Terms and definitions

Connection: A connection is typically defined as a link to the outside world. For example a link to a mobile network or a link to a database server would be a connection. Connections are able to receive and send messages. Hardware requirements depend on the number of connections you wish to setup.

Message throughput: The number of messages that travel through the system. It is measured in Messages per Second (MPS) or for lower capacity systems in terms of Messages per Minute (MPM). The message engine in Ozeki was designed to handle a maximum of 1000 messages per second on a single computer. Higher throughput can be achieved using multiple computers.

CPU: Bursts of high message throughput require higher single core performance. A high number of connections require higher number of thread processing capabilities. When choosing a CPU hierarchy for your system consider how you wish to use Ozeki. For best performance we recommend top of the line Multi core Intel CPU's. AMD CPUs are supported based on their equivalence to the suggested Intel CPUs.

Memory: For increased preformance, Ozeki caches message queues in memory. Make sure to put as much RAM into your system as possible, since this will greatly improve your system's performance.

Network: Ozeki can operate on lower network speeds, but a 1Gb LAN network connectivity is recommended. Depending on the number of simultaneous connections and the message throughput the network bandwidth can be a limiting factor.

Supported operating systems

Ozeki 10 SMS Gateway supports the following operating systems. All operating systems must be installed in their x64 version. 32-bit versions are not compatible with Ozeki. Full Windows and Linux updates are also mandatory to be applied to ensure compatibility with Ozeki.

Ubuntu LTS 20.04
Raspbian Stretch
Windows 10 (Home, Pro, Enterprise)
Windows Server 2016 (Standard, Datacenter)
Windows Server 2019 (Standard, Datacenter)

System sizes

Small system:
The number of connections is up to 10.
The message throughput is up to 1 MPS (message per second).

Medium system:
The number of connections is up to 20.
The message throughput is up to 25 MPS (message per second).

Large system:
The number of connections is up to 50.
The message throughput is up to 100 MPS (message per second).

The message throughput is up to 500 MPS (message per second).

Enterprise+ system:
The number of connections is up to 200.
The message throughput is up to 1000 MPS (message per second).

Hardware variants

Ozeki supportes and was tested on both bare metal systems and virtual machines. All systems (hardware CPUs and virtual CPUs) must offer the 64bit instruction set.

Supported virtual machine platforms:
VMware vSphere Hypervisor (ESXi) 6.X and above
Microsoft Hyper-V Server 2012 and above
Hyper-V on Windows Server 2012 and above
Citrix XenServer 8.0 and above
KVM 2.6 and up.
