Getting started with KHIKA

Introduction

When setting up and configuring KHIKA in your organisation network, you need to perform few steps and shall find this page helpful for the same. For more information on KHIKA components you can click here.

KHIKA Virtual Appliance

KHIKA is available as a Virtual Appliance which can be provisioned on your organisation’s VMware platform. There is at least one KHIKA core app server VM. In addition, there can be optional collector nodes or KHIKA aggregator VMs, one at each location where the data sources are present. For more information refer to KHIKA Data Aggregator.

Download the KHIKA Virtual Appliance in the form of a .ova file on your VMware platform.

Pre requisites for KHIKA VA

We recommend following hardware resources to be allocated to the KHIKA VMs for optimum performance.

KHIKA Central Server

CPU= 16 vCPU
Memory = 64GB
Disk1=500GB (for KHIKA Application, OS etc)
Disk1 = 2 TB (To begin with for storing KHIKA data.)
Network= Fast ethernet with static IP
OS: Bundled with KHIKA Virtual Appliance

KHIKA Aggregator

CPU= 16 vCPU
Memory = 16 GB (to process incoming volume of data with high speed)
Disk1= 500GB (for KHIKA Application, OS etc)
Disk1 = 500GB (to store immediate data and some buffer in case of connection loss)
Network= Fast ethernet with static IP
OS: Bundled with KHIKA Virtual Appliance

Minimum Hardware sizing you require depends on the volume of your data. You can refer the table below :

Hardware calculation Table

Data expected in GBs per day	CPU Cores	Memory in GB	Disk
10 to 24	8	16	500G SSD or 15K RPM
24 to 48	12	64	500G SSD or 15K RPM
48GB and more	Needs customized distributed architecture (contact sales for Professional Services)

Import the KHIKA Virtual Appliance

Download or transfer the KHIKA VA .ova file on the required server. This section considers a VMware Workstation environment in which we shall setup the KHIKA VA.

In the VMware workstation, start by clicking on “Open a Virtual Machine”

A browser window opens which prompts you to select the .ova file, the KHIKA virtual appliance which is present on your local machine. Select the file and click Open. Another pop up window appears where you can rename it if required, or select another file by clicking on “browse” again. Verify the details and click on Import.

After the .ova file is successfully imported, it is seen as follows in the VMware workstation

Allocate Resources

In the left panel, we can see the name of our virtual image. Right click on it go to Settings.

Following window opens with options to allocate compute resources to this newly created virtual appliance.

Click on the options Memory, Processors, Hard Disk one by one and on the right side of the window, allocate enough resources for the selected component. Click on Add button in the bottom, for additional resources. In the new pop up, select Network Adapter and click on Finish. Network Adapter is required for the VM, so that we can connect using an IP address to this VM.

Please ensure the hardware pre requisites discussed in the section above, are present on your server, so that it can be allocated to the VM.

Boot the Appliance

Now click on the option “Play virtual machine”

The VM shall boot after this step.

After booting successfully, you shall be prompted to login into KHIKA.
