17 Power clients are accelerating their transition to cloud models Live partition mobility (LPM) has become essential it is no longer a high-end option Proof point: PowerVM call home logs show a dramatic increase in LPM activity 17

18 PowerVC Setup and Configuration Simple, Intuitive with a Focus on Time to Value 1. Add Storage to be managed Provide IP address Provide user-id & password 2.Add Servers to be managed Provide IP address of IVM/HMC Provide user-id & password 3. Add Network Template Provide VLAN ID Provide IP Configuration Configuration Placement Policies Stripe Virtual Machines Pack Virtual Machines

19 Ensuring the PowerVC Environment is Operational and Healthy Verify the both the management server and managed systems Management Server Checks Operating System pre-requisites Network configuration PowerVC processes DB2 configuration File system space Communication with all resources Server Checks Required VIOS levels and mode Host network configuration Valid machine types and models Maximum number of hosts Storage Checks Valid machine types and models LUN Visibility test Required SVC firmware level Runs interactively from the Home page of the console Runs from the command line when the management server is not started Produces and saves the last report - viewable at any time Proactive identifies root cause of environmental problems that would result in failures

20 Virtual Machine Management Providing the fundamental visibility and management for Power virtual machines Virtual Machine Management Start and stop the virtual machine Delete the virtual machine Capture VM as Image Resize including DLPAR Migrate using placement policy Virtual Machine Health Virtual Machine State Virtual Machine Status Red/Green/Yellow Indicators Virtual Machine Properties Processor, memory, disk Related host information Network configuration Disk volumes (separate tab) VIOS VIOS Linux PowerVM Power System AIX Migration non-disruptive relocation of a virtual machine VIOS VIOS Linux PowerVM Power System AIX The target host can be selected by the user or selected based on the placement policy Striping Policy Packing Policy

21 One Click System Evacuation Provides easy, graceful way to prepare for maintenance Automatically relocate all virtual machines to other machines Use the PowerVC scheduler to determine the target host or manually select the destination host Clears the system of virtual machines without excessive administrator work Alternatively, fence off the physical host to prevent new virtual machines from being deployed or moved to that host Option to allow administrators greater control of relocation operation

22 PowerVC Host Groups PCI Host Group Host Groups allow the PowerVC administrator to create a logical boundary around a group of physical servers Each server can only be in one host group Deployment, mobility and remote restart are only allowed within the group Each group has its own placement policy Hosts are placed in the default group when added Host 1 Host 4 Host 7 POWER8 Host Group Austin Host Group Host10 Sandbox Host Group Host 8 Host 9 Host 5 Host 6 Host 2 Host 3 Host11 Host 12 Default Host Group Host 13 Host 14

23 PowerVC Advanced Placement Scheduler support VM placement based on CPU & Memory capacity and CPU Utilization Free CPU / Memory Capacity The PowerVC scheduler takes the capacity of servers into account to determine which host to deploy or relocate VMs to. Hosts with the greatest free CPU or memory allocation becomes the target of the next VM. The scheduler can also take host CPU utilization into account when scheduling VMs CPU MEMORY Scheduler choice Host CPU Utilization Scheduler choice CPU MEMORY CPU MEMORY Host 2 Host 5 Host 7 Host10 Host 8 Host 9 Host11 Host 13 Host 14 23

24 PowerVC Co-location Affinity and Anti-affinity VM with no affinity requirements can go anywhere within the host group VMs with affinity must be placed on the same host VMs with anti-affinity cannot be placed on the same host Affinity and Anti-affinity provide control over which VMs can be placed on the same host - VMs with Affinity must be deployed to the same host - VMs with Anti-Affinity must not be placed on the same physical host Host 1 Host 2 Host 3 24

25 PowerVC Placement Policies Policy Description Initial Placement Packing Pack workload on fewest physical servers Maximizes usable capacity, reduces fragmentation, reduce energy consumption ü Striping CPU Balance Spread workload across as many physical servers as possible Reduce impact of host failures, higher application performance Place VMs on the hosts with the least allocated CPU Higher application performance ü ü Memory Balance Affinity Anti- Affinity Place VMs on the hosts with the most available memory Improve application performance Affinity specifies that VMs should be placed on the same host or few hosts Useful for collocating VMs on the same host(s) Do not place VMs on same host Useful for ensuring VMs are not collocated Availability cluster support (e.g. PowerHA) Higher application performance ü ü ü 25

26 PowerVC Dynamic Resource Optimizer Policy-based automation to balance workloads PowerVC Dynamic Resource Optimizer allows for automated rebalancing of workloads between servers Server workload can be automatically balanced two ways: Relocating Virtual Machines between servers Moving processor capacity between servers using Enterprise Capacity on Demand Works with AIX, IBM i or Linux VMs for Compute Resources Works with AIX or Linux VMs for Memory resource balancing Option to balance on Compute or Memory resources. Move server Capacity with COD Relocate VM Relocate VM Host 1 Host 2 Host 3 26

27 Dynamic Resource Optimizer (DRO) Host Groups Forms a domain for optimization (i.e., restricts where VMs can be moved) Attached are the following attributes to specify optimization behavior Enabled specifies whether optimization is active for the group; default is off DRO policy specifies the optimization policy (CPU utilization only for 4Q15) Action specifies the engine s mode (i.e., either migrate or advise only); default is advise only Threshold specifies the point at which a host is considered to violate its DRO policy (e.g., 80% CPU utilization); default is 70% Run interval specifies how often (in minutes) the engine will check whether hosts are violating their policy; default is 5 minutes Stabilization specifies the number of consecutive times [spaced run interval minutes apart] a host needs to violate its policy before action will be taken; default is 2 times Max migrations specifies the maximum # of migrations that can be occurring in parallel within the host group; default is 10 migrations

28 Enabling DRO

29 Viewing DRO Events

30 Dynamic Resource Optimizer (DRO) Hosts Can become violated (e.g., CPU utilization exceeds 80% for X period of time) Can selectively disable ongoing optimization for a host (implicitly disables DRO for its VMs) A host s CPU utilization is: From a host perspective, polled once per minute via the nova monitor framework (i.e., NOT Ceilometer) and stored in nova.compute_nodes::metrics (only the last value is retained by the out-of-box OpenStack monitor framework); this leads to From a DRO perspective, polled once per minute, albeit calculated as an average of the last 15 data points (these data points are retained within an in-memory PRS cache) Net a 15-minute running average that is updated once per minute Can be a target host for at most one optimization migration at a time (i.e., let things cool down before migrating additional VMs to a host); could make this more aggressive in a future release Virtual Machines Can be migrated to rebalance the environment A VM s CPU utilization percentage is periodically cached as a power spec (for purposes of optimization calculations, it s calculated as an average over the past 15 minutes)

31 Dynamic Resource Optimizer (DRO) What happens when a host is deemed violated? Which VM is attempted to be moved first? > If there are any VMs that will *predictably* bring the host below its threshold, the VM with the lowest memory [of that set] will be selected (the lowest memory VM is selected because there are fewer bits to migrate) > Otherwise, the VM that will make the largest predictable reduction in the host s CPU utilization will be selected What host is selected as the target host? > The host that will have the lowest anticipated CPU utilization post-migration such that the optimization threshold will **not** be violated (otherwise we will likely be playing ping pong between hosts) How is a target host s post-migration anticipated CPU utilization calculated? > target_host.cpu_percent + VM.cpu_percent * VM.vcpus * source_host.cpu_frequency / target_host.total_vcpus * target_host.cpu_frequency What Power configurations are support by DRO? Live Migration-based DRO KVM PowerVM (HMC and NovaLink) CoD-based DRO PowerVM (HMC only; NovaLink doesn t support CoD)
