Annex 9: Private Cloud Specifications

Transcription

1 Annex 9: Private Cloud Specifications The MoICT Private Cloud Solution is based on the Data Center Services (DCS) offering from CMS. DCS is comprised of a fabric in the form of one or more resource pools (clustered hosts running a supported hypervisor) and a fabric management component (System Center 2012 and associated products). A high level view of this relationship is provided below. Figure1: High-Level DCS Component Relationships While the implementation of each architecture varies based on the size, resource pool make-up (and versions), number of physical locations and workloads running within the DCS environment, the solution provides comprehensive IaaS services in a single architecture. Fabric Management DCS provides out-of-box (OOB) System Center virtualization infrastructure management capabilities with the core System Center products installed as part of the solution. The following products are leveraged within the Solution: Cloud Services Process Pack System Center Service Manager 2012 System Center Operations Manager 2012 System Center Virtual Machine Manager 2012 System Center Orchestrator 2012 Note: the fabric management components can be used to manage multiple fabrics without redeployment or re-development. If the government is to provide cloud services to the private sector, the fabric itself needs to be hosted on separate hardware, and on a separate network, for security purposes. This is so that government and non-government services are not mixed within the same hardware/network. The solution design will address this point. 1

2 Virtual Machine Manager DCS requires System Center Virtual Machine Manager Two (2) SCVMM servers will be deployed and configured in a failover cluster during hydration using a dedicated SQL instance on the DCS virtualized SQL cluster. Operations Manager DCS requires System Center Operations Manager Two (2) servers will be utilized one supporting up to 3000 OpsMgr agents and one providing high availability. Operations Manager Installation uses a dedicated SQL instance on the DCS virtualized SQL cluster. The installation will follow a split SQL configuration : SQL Server Reporting Services (SSRS) OpsMgr components will reside on the OpsMgr VM Service Manager DCS requires System Center Service Manager DCS installs the Service Manager Management Server on two virtual machines. A third virtual machine hosts the Service Manager data warehouse server. Both the Service Manager database and the data warehouse database use a dedicated SQL instance on the DCS virtualized SQL cluster. The Service Manager portal is hosted on a fourth system with the DCS Portal. Orchestrator DCS requires System Center Orchestrator 2012 and the System Center integration packs for Orchestrator. The Orchestrator installation uses a dedicated SQL instance on the DCS virtualized SQL cluster. DCS hydrates two Orchestrator Runbook servers for High Availability and scale purposes. Orchestrator provides built in failover capability (it does not use failover clustering!). By default, if an Orchestrator server fails, any workflows that were running on that server will be started (not restarted) on the other Orchestrator server. The other reason two Orchestrator servers are deployed by default is for scalability. By default each Orchestrator Runbook server can run a maximum of 50 simultaneous workflows. This limit can be increased depending on server resources, but an additional server is hydrated to accommodate larger scale environments. Data Protection Manager System Center Data Protection Manager (DPM) 2012 is not hydrated by default in DCS v2.0 however it is installed and configured as part of a DCS solution. DPM enables VM level backups, while with customization file-level back-up will be implemented. To enable DPM, the DPM agent is installed in each desired VM and a protection group created for each. The DCS portal then can enable VM selfservice file recoveries. Configuration Manager Just like DPM 2012, System Center Configuration Manager (SCCM) 2012 is not hydrated by default in DCS however it can be installed and configured as part of a DCS solution. SCCM enables advanced inventory, configuration of baselines and other key features delivered by the product. A Primary SCCM 2

3 Server is installed to handle the inventory, software distribution and software metering. Redundancy is accomplished through the Hyper-V cluster. DCS Portal Server DCS provides a dedicated portal interface to expose System Center functionality and allow for provisioning and management of IaaS resources. The Cloud Service Process pack in the Foundation and Advanced configurations is utilized to support out-of-box functionality with respect to IaaS management. This solution is illustrated in the diagram below with the servers/technologies hydrated by DCS 2.0; Fabric Figure 2:DCS 2.0 General Architecture 6 nodes of Hyper-V cluster where implemented in the Production Data Center a sample of the implementation figure is illustrated below. 3
