私有云POC用户指南

The Private Cloud-POC is a self-contained virtualised management infrastructure which can be deployed in a suitable environment to show the use of Microsoft Technologies in provisioning and managing Virtual Machines. This document covers the deployment details to allow the technical personnel involved in deployment the solution to understand what components are involved and how they are configured.

The Private Cloud-POC User Guide provides the information you need deploy and Configure the Virtual Machine Manager Self-Service Portal (VMMSSP, or the self-service portal) in your datacenter and Exchange Server.

About this Document

This document is for Private Cloud and provides a deployment scenario for self-service portal component guide and Exchange Server Mailbox.

Intended Audience

The intended audience of this document is the technical personnel engaged in implementing the Virtual Machine Manager Self-Service Portal and Exchange Services solution within their own environment.

Document Scope

The scope of this document is concerned with Microsoft technologies only.

Constraints and Assumptions

The server and storage hardware required for the GPC-POC
environment is as specified by the hosting partner provided it meets the minimum requirements as defined in this document.

There are also a lot of related conditions and technologies that will have an impact on the GPC-POC working. Some of those assumptions are listed in the table below:

Assumptions	Explanation
Physical environment	It is assumed that a server environment exists with enough floor space, power, air conditioning, physical security etc.
Stable network	It is assumed that the local and wide area network infrastructure which includes physical components switches, routers, cable etc. And the logical components like routing, broadcasts, collisions etc. Are stable and under control. Having an unstable network can result in unexpected behavior.
Namespace	Maintain Isolated / Unique Namespace
Network Support	Failover / Router / Configuration needs to be performed by IT staff.
Constraints	Explanation
DHCP Required	DHCP is required for VM Provisioning
Network Bandwidth	1 GB network bandwidth
Multiple VLANS / NICS	Multiple VLANS / NICS required for Clustering, Live Migration and Heartbeat
iSCSI Hardware	Required 500 GB – 1 TB on iSCSI

Table 1: Constraints and Assumptions

Known Issues

No limitations on the number of VMs that a user can request. Potential future enhancement.
Cannot remote control a Linux machine currently (as there is no RDP connectivity). Potential to implement a telnet/X-Windows session instead in the future.
No automatic SCOM agent install for provisioned Linux machines. Potential future enhancement to include the agent in the source.

All Virtual machines are provisioned on same network and as such users can see all other machines on the network (but do not have logon access). Potential future enhancement to build VMs into separate VLANs but needs consideration of management infrastructure.

High-Level POC Architecture

Figure 0.1: High Level POC Architecture

POC is intended to be delivered on harddrive for installation at customer site with limited hardware investment.
It's only require 6-8 physical machines
Goal is to demonstrate IaaS & SaaS scenarios for Private Cloud deployment environment.
The POC uses a Windows iSCSI server instead of a SAN for portability reasons. iSCSI is a storage protocol used to connect to a network device that moves storage-related data. It allows clients to send SCSI commands to remote, consolidated storage targets (or disk arrays) in the same way the client can interact with a locally attached disk. A common misconception is that you can connect iSCSI over your existing LAN infrastructure.

High-Level Scenarios

High-Level Showcase Scenarios (10-15)
IaaS (Dynamic Datacenter)	SaaS (Exchange)
1. New tenant (organization) sign-up	1. New tenant (organization) sign-up
2. New environment provisioning request	2. New tenant services configuration
3. Virtual machine request	3. Tenant admin set-up
4. Virtual machine template setting	4. New user (mailbox) addition
5. Virtual machine provisioning	5. Distribution list management rights assignment
6. Reporting	6. Charge back reporting

Sequence Diagram for Iaas & SaaS

Figure 0.2: Sequence Diagram for Iaas & SaaS

Following are the sequence diagram steps

Business Group Customer requested for Emailbox setup for the department / organization.
Request goes to IT Aministrator of the department / organization. IT Admin enters the New Machine request through Website Form.
It goes to Data Center Admin approval for VMs aqquision. Once approved, approval mail sent to IT Adminstrator.
IT Administrator request for the VM Servers.
IT Administrator configure and installs the Exchange on VM Servers.
IT Administrator Provision and Add Tenant and Mailbox for users.
Finally the request gets completed and mail been send to BG Customer to utilize the services.
Report gets generated based on the service(space, bandwidth, etc..) usage and charge back to the department based on the usage.
1. Solution Design

The GPC-POC is based on a self-contained domain environment consisting of a number of management servers to support a scalable Hyper-V cluster onto which the solution will provision multiple Virtual Machines:

Figure 3: Hyper-V cluster Nodes with Virtual Machine

In order to make the solution as portable as possible, the management servers are themselves provided as virtual machines. This allows them to be scaled at the virtual host level to higher levels of memory/processor and disk as required without losing any portability.

The actual GPC-POC components in the handover consist only of the virtual machines making up the management servers. The associated Hyper-V Cluster needs to be created after the management servers are in place in the environment as it will need to be joined to the GPC-POC domain.

Providing a Hyper-V Cluster as the Virtualisation platform allows for fast transfer of the virtual machine servers to a different physical server in the event of unexpected hardware failure of the host. Live Migration will be used in the event of scheduled maintenance on the host servers and will provide continuous service with no outage or service loss.

The sections below covers the detailed configuration for the GPC-POC Infrastructure Environment.
