11 What challenges does VMControl address? Challenges of virtualization Several interfaces to manage virtual servers across systems New workloads difficult and time consuming to implement Increase in management costs of virtual servers Workload resiliency can degrade in a virtual environment How VMControl address those challenges Consolidates management to a single pane of glass (Systems Director) Automates the management of a virtualized infrastructure Improves workload resiliency Reduces deployment time for new virtual servers 11

12 What is a Virtual Appliance This is a package that contains A virtual server definition that meets the requirements to run it s associated image, where the image contains the operating system and any software The virtual server image may contain A supported operating system (AIX or Linux on System z) Any software applications that you wish to have run on that operating system The Virtual Appliance is described using the methods described in the Open Virtualization Format (OVF) specification. An industry standard representation of a virtual server that contains a configured, tested operating system and middleware and software applications, along with the metadata that describes the virtual server OS meta-data Virtual Appliance 12

13 What is a Workload Group virtual servers that contribute to an application workload or service Summarize health and status of the composition of virtual servers Aggregated monitoring A workload is created when you deploy a Virtual Appliance Workload 13

14 VMControl Images Repository For AIX, you have two options: NIM image repositories VIOS image repositories (SCS) You can set up your AIX environment with either type or with both types. 14

15 NIM Image Repository NIM Master image repository for virtual appliances containing AIX mksysb and lpp_source images. 15

16 VIOS images repository Storage Copy services Virtual I/O Server (VIOS) image repository for virtual appliances containing AIX or Linux on Power Systems raw images. 16

17 Introduction to VMControl Storage Copy Services (SCS) The Common Repository (CR) is A SAN Storage Pool created for SCS use Created in VMControl and associates the Storage Pool with an Image Control Point (VIOS) The CR Storage Pool contains only the raw binary OS images (not mksysb or OVF) OVF information associated with each image/volume in the Storage Pool is kept on the SD Server and also on the Image Control Point The CR Image Control Point (ICP) Is a VIO Server that has Systems Director CAS and CR Subagent installed Is a VIOS that is associated with a Common Repository Contains OVF information (duplicated from SD) associated with each raw image in the CR Can be moved from one VIOS to another in case of VIOS maintenance or failure Can control more that one repository 17

18 Introduction to VMControl Storage Copy Services (SCS) Storage Copy Service (SCS) based provisioning is A new plugin feature introduced in VMControl Standard Edition A faster method of capturing and deploying Virtual Appliances A provisioning service that allocates Virtual Servers, SAN resources, and copies OS images via VIOS dd copy or SVC/V7000/DS8000 Fast Copy (for both deploy and capture) A provisioning service that uses VMControl Common Repository to manage and deploy AIX/SUSE/RHEL raw images A method that uses VIOS as the Image Control Point for the CR repository Capable of deploying VAs from a VMControl CR as new Power platform virtual servers or onto existing virtual servers on Power platforms 18

20 New VMControl 2.4 UI wizard and CLI creates CR image repositories 20

21 SCS VMControl 2.4 Activation Engine Customization information from UI (ip configuration) is built into an OVF Environment Document ovf.env.xml A virtual optical drive is created and attached to new virtual server and ovf.env.xml document file is loaded into drive. Allows the document to be accessible to the activation engine when the new virtual server boots up Requires at least one VIOS OS be discovered and have access on the host system where new virtual server is deployed Timer is used to remove the virtual optical drive after an hour If director ended and restarted in that hour virtual optical would be removed when virtual server is relocated 21

22 SMI-S providers for IBM Systems Director A SMI-S provider is a vendor-specific module that is used so that independent management software, such as IBM Systems Director, can manage a vendor device using a standard interface based on the Common Information Model (CIM) protocol. IBM Systems Director communicates with the storage devices through their respective SMI-S providers 22

24 Deploying a Virtual Server Image The VS image meta-data is used to create VS container, allocating the required platform resources. Storage is dynamically allocated and attached to the virtual server. The VS is dynamically attached to the appropriate networks and VLANs. The virtual server is started from the bootable disk image and customized as part of its initial boot.

31 VMControl Server System Pool Groups similar hosts with the goals of better resource usage and workload resilience Consists of: Multiple hosts (managed systems) Associated virtual servers Attached shared storage Can be used for: Deploying virtual appliances The target host is selected automatically Once a host is assigned to a server pool, you cannot deploy directly to that host Relocating virtual servers from one host to another host in the pool Manual relocation Automatic relocation using the resilience policy Automatic relocation using command automation Viewing server system pool status using a dashboard Status of all resources in the pool Monitors, such as CPU Utilization Hosts Virtual Servers Shared Storage 31

32 Supporting Existing Systems and Workloads System Pools can be defined from a combination of new and existing system within the data center. For new systems, all of the systems capacity is added and managed as part of the pool. For existing systems, all of the remaining capacity is added and managed as part of the pool. Any pre-existing workloads are recognized, however not managed within the systems pool. Image Library Existing workloads can be migrated to a system pool. Capture existing workload Deploy workload to System Pools System Pool 32

33 Deploying a Virtual Appliance to a System Pool Image Library Deploy OS meta-data OS meta-data Capture meta-data OS meta-data Workload A VA representing a multi-tiered applications workload is selected for deployment* Intelligent placement of the virtual servers within the pool of systems provides simplification and optimizations. Understanding of the composition is maintained and used in the ongoing management of the running workload. System Pool 33

34 Server Pools provide Workload Resilience One of the major goals of server system pools is to provide resilience for your virtual servers and the applications running on them Resilience is provided by relocating one or more virtual servers to another host In the Power environment there are several options for achieving resilience (ISD virtual Farms and System Server pools) 34

35 Relocation Using VMControl Server Pools Live relocation only Manual relocation VMControl chooses the target; user can accept or cancel the relocation Automatic relocation using resiliency policy Assign hosts to a server system pool; set resilience policy for the pool VMControl monitors host(s) in the workload for a predicted hardware failure If a failure is predicted, VMControl will relocate affected virtual servers to another host in the pool Workload automation policy = Advise; user must approve/disapprove the relocation Workload automation policy = Automate; relocation performed automatically Automatic relocation using an event automation plan Create an event filter to trigger on any event or set of events Create an event action to run smcli vmcrelocate to relocate the affected virtual server(s) basically you are doing a manual relocation under the control of an event automation plan 35

36 Workload Resilience within a System Pool Relocate Virtual Servers between Hosts within the Pool Determine best host placement within the pool Supports single virtual servers and host evacuation Move virtual servers away from a failing host system Automate relocation and placement of virtual servers in response to predicted host system failures with no disruption. Resilience policy associated with the workload Provide workload resilience yes/no Enables host system monitoring for failures and predictive failures Automates recovery action based on desire level of automation Users can add automation for custom thresholds System Pool Automation policy associated with the workload Automate = Require Approval / Automate Require Approval VMControl recommends actions and requires approval Automate VMControl automates actions 36 View In Animation Mode
