+# Prerequisites
+
+## Hardware Requirements
+
+Based on the description of "Generic Hardware Guidelines" <https://guide.opencord.org/prereqs/hardware.html#generic-hardware-guidelines>, we are going to introduce the specific requirements for COMAC in this page.
+
+
+* **Compute Machines**: Same as described in "Generic Hardware Guidelines" page. But you want to use multi-cluster COMAC, then you can prepare two same setups. Also, COMAC requires at least Intel XEON CPU with Haswell microarchitecture or better.
+
+* **Network Cards**: For 3GPP data plane, COMAC supports high performance with SR-IOV interfaces. So besides the first 1G NIC for management, COMAC also need another 10G NIC on computer machines for user data traffic.
+
+* **Access Devices**: In COMAC, the access devices here refer to Enodebs. The enodeb for this release we use Accelleran E1000.
+
+The rest of the hardware are same with "Hardware Requirements" section on "Generic Hardware Guidelines" page.
+
+## COMAC BOM Example
+
+One cluster with one OpenFlow switch setup example:  
+![](../images/3nodes-hardware-setup.png)
+
+3x x86 server (10G NIC)  
+1x OpenFlow switch (40G NIC)  
+1x DAC breakout cable     
+5x Ethernet copper cables 
+2x layer 2 switches, one is for management, another is as converter between 1G and 10G NICs  
+
+## Software Requirements
+
+* **Kernel Modules**:  
+  (1) “*nf_conntrack_proto_sctp*” for SCTP protocol;  
+  (2) “*vfio-pci*" for SR-IOV.
+  
+* **Software List**:  
+   Download kubespray, automation-tools, configurations and the helm charts:
+
+  `git clone https://github.com/kubernetes-incubator/kubespray.git -b release-2.11`
+  `git clone https://gerrit.opencord.org/automation-tools`
+  `git clone https://gerrit.opencord.org/pod-configs`
+  `git clone https://gerrit.opencord.org/helm-charts`
