• DOCUMENTATION
• GETTING STARTED
• The following documents assist administrators involved in the deployment, operation, and maintenance of a virtual environment powered by the current release of XenServer (v7.5 CR).

• QUICK START GUIDE
• The XenServer Quick Start Guide walks through the installation and configuration essentials to get XenServer and its graphical Windows-based user interface, XenCenter, up and running.

• DOWNLOAD FROM CITRIX.COM

• CONFIGURATION LIMITS
• The XenServer platform is tested to perform in a number of virtualization scenarios. The configuration limits used for those tests are listed in the Configuration Limits document. While it may be possible to exceed the stated limits and have a functional XenServer installation, those seeking support for their installation from Citrix should be aware that operation outside of the configuration limits may make it difficult to deliver support for such an environment.

• DOWNLOAD FROM CITRIX.COM
• RELEASE NOTES
• The release notes contain detailed information on new features, known issues, compatibility, and installation. Note that some features listed may require a commerical license.
• DOWNLOAD FROM CITRIX.COM
• GUIDES
• The following documents are designed to provide detailed guidance on the installation and administration of a XenServer environment.
• INSTALLATION GUIDE
• This installation guide provides guidance for multiple deployment scenarios. When planning a new XenServer installation, this guide should be used as a reference.
• PHYSICAL TO VIRTUAL CONVERSION ABILITY:-
• Citrix® XenConvert™ is a physical-to-virtual (P2V) conversion tool for converting a Windows operating system, applications, and data from a physical machine to a XenServer virtual machine, Provisioning Services vDisk, virtual appliance in the Open Virtualization Format (OVF), or disk image in the Virtual Hard Disk format.

TASK 2
-vMware architecture that allows enterprises and small businesses to transform, manage and optimize their IT systems infrastructure through virtualization. Different servers with vmware software isinstalled and attached to a gigabit network and SAN would be used for backup in case of any 1 failure of san disk moreover all data is stored directly attached to storage devices.
My architecture allows multiple virtual machines with operating systems and applications to run in isolation, side-by-side on the same physical machine. A virtual machine is the representation of a physical machine by software. It has its own set of virtual hardware (e.g., RAM, CPU, NIC, hard disks, etc.) upon which an operating system and applications are loaded. My environment includes different servers and SAN which already discussed in above question.
Meets the business requirements by following reasons: –
• Speed the delivery of business services applications and services.
• Optimize existing IT infrastructure by reducing the cost and complexity of delivering applications, desktops, or developer environments
• Provide a superior end-user experience
• Dynamically deliver applications without interrupting users
• Optimized application delivery drives down compute, network, and storage costs
Description of an architecture: –
1) install vmware on every ESX servers’ hosts.
2) provided with 1 switch.
3) having 1 SAN – 4 TB of storage and FreeNAS installed, this should allow plenty of room for the annual increase in the customer and booking database.
4). To ensure 100% availability uptime for the WEB, SQL servers and all other servers, I would have 2x1gig NICs to each and enable fault tolerance on those VMs.
5) all servers are attached to a gigabit network.
6) convert all physical servers into the virtual environment.
The rational for any design decisionsmade:-
VMware ESX Server – A virtualization layer run on physical servers that abstract processor, memory, storage and networking resources to be provisioned to multiple virtual machines
Fault Tolerance – enables a system to continue operating properly in the event of the failure.
VMware VMotion – Enables the live migration of running virtual machines from one physical server to another with zero downtime, continuous service availability and complete transaction integrity
VMware High Availability (HA) – Provides easy-to-use, cost effective high availability for applications running in virtual machines. In the event of server failure, affected virtual machines are automatically restarted on other production servers that have spare capacity.
Task 3
3 hosts – 12 GB split between them, each with 2x 1Gig NICs.
1 SAN – 4 TB of storage and FreeNAS installed, this should allow plenty of room for the annual increase in the customer and booking database.
1 switch – Used for the management network and SAN.
5 Ethernet cables- For the connection to and from the management/SAN network switch.
VMware- Installed on the 3 hosts
Web and SQL virtual servers
FreeNas and iSCSI’s (Internet Small Computer Systems Interface)
Task 4
Install ESXI client on all hosts, as well as running FreeNAS on the SAN. Set up the IP addressing on the client to communicate to the network and assign an IP address on a separate network for the SAN.
Convert all the servers to virtual machines using the standalone converter tool, and then migrated them to the SAN storage.
Install the vCenter Server Manager tool and when logged in create a cluster using the hosts. Then set up High Availability and DRS, with 100% availability set up on the Web and SQL servers.
Finally test all the virtual machines to ensure smooth operation and proper function across the network.
Task 5
Post deployment would involve verifying that all virtual machines functioned correctly, all operating systems functioned as they should, and that the VMs had network connectivity to the network, each other, and storage.
HA and DRS would be tested by overloading certain hosts to see if they would be swapped to the next available host, and also by cutting power/connection to a certain host to see if that host’s VMs would be transferred to the next available quickly and effectively without disruption to the VMs operation.
