Posted on by SandeepKaushik and ShaswatiMukherjee

This article will let you know that how to Create a Network Load Balancing Cluster for your Terminal servers or Storefront Servers.

 

What is NLB (Network Load Balancing)?

 

Network load balancing distributes the traffic load between members of NLB servers through which come through TCP/IP.
The best example where we can use is Jump box and Citrix Storefront etc.
(Jump Server – they are the servers from which we can do RDP of servers to manage devices in a separate security zone or within the same zone)

 

 This is basically used in big environment where your users login frequency is high. This will help to them to serve in a better way.
  1. NLB support 32 servers in a single cluster
  2. You can add Host to NLB cluster without bringing down the cluster vice versa for deletion hosts
  3. Detect and recover host that fails or goes offline.
  4. Automatically load the balance when you add hosts or remove
  5. Within 10 seconds it can redistribute and recover the load
Easy to manage: You can manage or add servers from a single server through NLB manager.

 

 

Prerequisites for NLB setup

  1. Two or more server.

  2. Two Network adaptor ( you can configure with one adaptor but it’s best practice)

  3. Use only TCP/IP

  4. Serve should be in domain

  5. All the servers which you want to add in this NLB should have Network Load balancing Features installed

 

Installation Steps:
1. Login into server and open Server Manager and go to Features

2. After that it will show you the entire features list.

3. Here you have to select Network Load Balancing and click next.

8. After selection you see IP and Subnet IP, click next.

 

9. Here you have to provide Cluster IP Address Click on add.

10. Here you have to provide IP for cluster, Full internet name and cluster operation mode.

 

11. If you want to configure Port rules then click edit and do the same.

Installing a guest operating system in a Virtual Machine

Posted on by SandeepKaushik and ShaswatiMukherjee

This Article describe about how to Install a guest operating system in a Virtual Machine

 

Step 1: Creating a Virtual Machine
A virtual machine is a software only representation of a computer. It is configured with one or more virtual CPUs, virtual memory, a virtual network interface card, and one or more virtual disks. An operating system and applications can be installed on the virtual machine after it is created.
Installing the Operating System
Step 2: Installing the Operating System
A VM cannot start up without first installing an operating system on a virtual disk associated with it. The easiest way to install the operating system on a VM is to attach an ISO and start it up from that ISO.
Install Updates and Fixes
Step 3: Installing Updates and Fixes
Installing the .NET Framework 3.5 Features on Server 2012
Many components are required as per environment like .NET Framework 3.5 to function correctly. You can avoid installing the .NET Framework separately by installing it on the VM before converting the VM to a template.
Licensing Virtual Machines with KMS
Step 4: Installing Hypervisor Tools
Hypervisor tools provide high performance drivers that significantly improve disk and network performance for XenServer and VMware VMs. You may not have all the commands required to manage the hypervisor (start, stop, suspend) and limited performance monitoring capabilities without these tools.

Installation Steps:

 

1. Double-click Citrix XenCenter on the desktop, if XenCenter is not already open then Click the Sandeep VM.

2. Click the Console tab.
If the VM fails to start, verify that the correct ISO is loaded in the DVD Drive field. If the ISO image is non-bootable, the VM will not start. To correct this issue, select the correct ISO image and then click within the Console page to start the VM

 

3. Select the desired language, time and currency format, and keyboard or input method, and then click Next. a. English (United States) is selected in the Language to install field.
b. English (United States) is selected in the Time and currency format field.
c. US is selected in the Keyboard or input method field.
d. Click Next.

 

4. Click Install now and Select Windows Server 2012 Standard (Server with a GUI) and then click Next.
Ensure you select the Server with GUI and not the Server Core Installation option.

 

5. Select I accept the license terms and then click Next > Select Custom: Install Windows only (advanced).

 

6. Verify Drive 0 Unallocated Space is selected and then click Next.
It will take approximately 15 minutes to install the operating system.
Note : Before installing OS just format this disk. Click on New > Then type the size which you want to allocate to this system > OK > After that click on Format > OK

After this install start and you can see progress %.

 

Important: Click Eject to the right of the DVD Drive field to unload the Windows Server 2012 ISO file.

 

Create a virtual machine in XenCenter

Posted on by SandeepKaushik and ShaswatiMukherjee

This Article describe about how to Create a virtual machine in XenCenter.

1. Double-click Citrix XenCenter on the desktop, if it is not already open.
2. Click XenServer in XenCenter and then click New VM in the XenCenter toolbar.
3. Scroll the VM template list, click Windows Server 2008 R2 (64-bit), and then click Next.
You are choosing the Windows Server 2008 R2 (64-bit) standard template, because this standard template is the closest match to Windows Server 2012. You will install Windows Server 2012 on this VM.

 

 

4. Type Name of server in the Name field and then click Next.
This is the name used to identify the virtual machine in XenCenter. It is not the DNS name or the computer name associated with the VM.

 

5. Select Install from ISO library or DVD drive, select Windows_Server_2012_64bit.iso in the ISO field, and then click Next.
The ISO files are stored in an ISO library that was pre-created and contains all of the installation images required for this course.

 

6. Select Place the VM on this server and then click Next.
If you had a pool of XenServer hosts, you could elect to not assign a home server. This allows the VM to be agile meaning it can run on any XenServer in the pool. In order to not assign a home server, you must have multiple XenServer hosts in a pool and create the VM on shared storage.

 

7. Verify that 1 or as per requirement vCPU is selected.
The number of vCPUs depends on the workload and should not exceed the logical cores within the hardware. The limit is 16 vCPUs per VM.

 

8. Type 8192 in the Memory field or as per your requirement and then click Next.
The recommended minimum amount of memory for Windows Server 2008 R2 is 1024MB. The recommended minimum amount of memory for Windows Server 2012 is 2048MB.

 

 

9. Verify that Use these virtual disks and Local storage are selected and then click Next.

 

10. Click Add > Select Network > Click Add> Click Next> Review the settings for this VM for accuracy.
If changes need to be made, use the Previous button to return to previous pages.

Here you can change your network settings like Vlan by clicking on Properties.

11. Verify that Start the new VM automatically is selected and then click Finish.
You may not want to start a VM automatically if you will not need it immediately or if you want to configure multiple VMs before making them available.
