    • What’s New in Windows Server“8” Beta for Hyper-V (Part 1)Damir BersinicSenior Platform AdvisorMicrosoft Canada Inc.damirb@microsoft.comTwitter: @DamirBhttp://blogs.technet.com/b/canitpro
    • Session Objectives and Takeaways• Session Objective(s): • Windows Server "8": The Definitive Cloud OS • Designed for Mission Critical, Scale Up • New Storage Options • Low cost, File Server Support • New integration with SAN • High Availability throughout the entire stack • PowerShell: Automation engine for cloud
    • Session Objectives and Takeaways• Why Windows Server "8" Hyper-V for Private Cloud • What did we learn from you & our Partners?• Platform Resiliency• Storage• Automation via PowerShell• We can’t cover everything in one session. • There is Part 2 coming up next…
    • The Definitive Platform for Cloud: Windows Server “8”.
    • Cloud Considerations• Mission Critical, Scale Up • VM Mobility Workloads • Networking• Storage – Multi-Tenancy, Security – Costs – IP Address Management – Complexity – QoS – Security • Automation/Manageability• Continuous Availability
    • Mission Critical Scale Up Workloads
    • Mission Critical Workloads• Scale isn’t just more virtual • Virtualization benefits such as processors, it’s balance Live Migration should just work – Compute – No tradeoffs – Memory • Virtualize workloads considered – Network I/O – Storage I/O “non-virtualizable”• Maximize hardware usage • Server resiliency, uptime and security is paramount• VM performance must increase – More resources and capacity with cores than ever
    • Scaling up: Physical NUMA NUMA node 1 NUMA node 2• NUMA (Non-uniform memory access) • Helps hosts scale up the number of cores Processors and memory access Memory • Partitions cores and memory into “nodes” • Allocation and latency depends on the memory location relative to a processor• High performance applications detect NUMA and minimize cross-node memory access Host NUMA
    • Scaling up: Physical NUMA NUMA node 1 NUMA node 2• This is optimal… Processors Memory • System is balanced • Memory allocation and NUMA node 3 NUMA node 4 Processors thread allocations within the same NUMA node Memory • Memory populated in each NUMA node Host NUMA
    • Scaling up: Physical NUMA NUMA node 1 NUMA node 2 Processors• This isn’t optimal… • System is imbalanced Memory • Memory allocation and thread allocations across different NUMA nodes NUMA node 3 NUMA node 4 • Multiple node hops • NUMA Node 2 has an odd number of Processors DIMMS • NUMA Node 3 doesn’t have enough Memory • NUMA Node 4 has no local memory (worst case) Host NUMA
    • Scaling Up: Guest NUMA• Guest NUMA • Presenting NUMA topology within VM vNUMA node A vNUMA node B vNUMA node A vNUMA node B • Guest operating systems & apps can make intelligent NUMA decisions about thread and memory allocation• Guest NUMA nodes are aligned with NUMA node 1 NUMA node 2 NUMA node 3 NUMA node 4 host resources• Policy driven per host – best effort, or force alignment

Host physical memory is capped at 32GB thus maximum VM memory is also restricted to 32GB usage. 2. vSphere 5.0 Enterprise Plus is the only edition that supports 32 vCPUs. All others support 8 vCPUs within a virtual machine. 13 3. For clustering/high availability, customers must purchase vSphere
    • Platform Resiliency
    • Deep HW Integration Protects Workloads• Errors detected outside of program detection• Predictive Failure Analysis
    • Isolate HW Errors & Prevent Poisoning1. Error detected outside of program execution (Patrol Scrub, LLC 4. Root marks the page as bad, adds it to EWB) the persistent bad page list, will not be allocated again2. During #MC handling, all VMs are suspended 5. The VM will be restarted (depending on a.

Determine if error can be isolated to a single VM resumed, execution will attempt to continue a. Search GPAspace backing all VMs a. Event is logged4. If the page is found in a VM, terminate the affected VM b. If the affected pages is consumed, a fatal error will occur a. VM is “powered off” & Event is logged Automatic, Maximum Protection with Windows Server "8" Hyper-V
    • Preventing Failure, Avoiding Disaster• Corrected Memory Errors (ECC errors) • Hyper-V support for PFA – Native OS Handling – Root OS forwards the address of the affected page – The Windows Hardware Error Architecture to the virtualization stack (WHEA) supports PFA for ECC memory – Hyper-V searches GPA space backing VMs for the – When the error count for a memory page affected page exceeds the PFA threshold, WHEA calls the – If the page is found in a VM (not locked or shared) system memory manager to take the • VM is momentarily suspended page offline • A new page is allocated, the affected pages is copied and • There is no guarantee that the page will actually freed, VM resumes execution be taken offline • An event is logged – WHEA adds the page to the persistent bad page list. – WHEA adds the page to the persistent bad page list Predictive Failure Analysis (PFA) Hyper-V support
    • Hyper-V Error Recovery Logging
