Hyper-V for dummies for VMware smarties

  1. 1. HYPER-V FOR DUMMIES FOR VMWARE SMARTIES ASBJØRN TONSTAD
  2. 2. System Resource Hyper-V (2012 R2) vSphere Hypervisor vSphere 5.5 Ent+ Host Logical Processors 320 160 160 Physical Memory 4TB 32GB1 2TB Virtual CPUs per Host 2,048 2,048 2,048 VM Virtual CPUs per VM 64 8 642 Memory per VM 1TB 32GB1 1TB Active VMs per Host 1,024 512 512 Guest NUMA Yes Yes Yes Cluster Maximum Nodes 64 N/A3 32 Maximum VMs 8,000 N/A3 4,000
  3. 3. Capability Hyper-V (2012 R2) vSphere Hypervisor vSphere 5.5 Ent+ Dynamic Memory Yes Yes Yes Resource Metering Yes Yes1 Yes Network QoS Yes No2 Yes2 Storage QoS Yes No2 Yes2 Storage API / Multipathing Yes No Yes
  4. 4. Granular In-box Capabilities • ARP/ND Poisoning (spoofing) protection • DHCP Guard protection • Virtual Port ACLs • Trunk Mode to VMs • Network Traffic Monitoring • Isolated (Private) VLAN (PVLANs) • PowerShell & WMI Interfaces for extensibility Layer-2 Network Switch for Virtual Machine Connectivity Virtual machine Network application Virtual network adapter Hyper–V host Hyper-V Extensible Switch Physicalnetwork adapter Physicalswitch Virtual machine Network application Virtual network adapter Virtual machine Network application Virtual network adapter
  5. 5. VHDX on Traditional LUN E:VM2 Data Protection, built in • Supports Used Disk Space Only Encryption • Integrates with TPM chip • Network Unlock & AD Integration VHDX on Cluster Shared Volumes C:ClusterStorageVolume1VM4 VHDX on File Server FileServerVM3 VHDX on DAS F:VM1
  6. 6. Significant Improvements in Interoperability • Multiple supported Linux distributions and versions on Hyper-V. • Includes Red Hat, SUSE, OpenSUSE, CentOS, and Ubuntu Comprehensive Feature Support • 64 vCPU SMP • Virtual SCSI, Hot-Add & Online Resize • Full Dynamic Memory Support • Live Backup • Deeper Integration Services Support Server Hardware IndependentHardware VendorDrivers Windows Kernel Virtual Service Provider Configuration Store Worker Processes ManagementService WMI Provider Hyper-V
  7. 7. • Secure Isolation for traffic segregation, without VLANs • VM migration flexibility & Seamless Integration Key Concepts • Provider Address – Unique IP addresses routable on physical network • VM Networks – Boundary of isolation between different sets of VMs • Customer Address – VM Guest OS IP addresses within the VM Networks • Policy Table – maintains relationship between different addresses & networks Network Isolation & Flexibility without VLAN Complexity 192.168.2.10 192.168.2.11 192.168.2.12 192.168.2.13 192.168.2.14 10.10.10.10 10.10.10.11 10.10.10.12 Blue Network 10.10.10.10 10.10.10.11 10.10.10.12 Red Network Network/VSID Provider Address Customer Address Blue (5001) 192.168.2.10 10.10.10.10 Blue (5001) 192.168.2.10 10.10.10.11 Blue (5001) 192.168.2.12 10.10.10.12 Red (6001) 192.168.2.13 10.10.10.10 Red (6001) 192.168.2.14 10.10.10.11 Red (6001) 192.168.2.12 10.10.10.12
  8. 8. Capability Hyper-V (2012 R2) vSphere Hypervisor vSphere 5.5 Ent+ VM Live Migration Yes No1 Yes2 VM LM with Compression Yes N/A No VM LM over RDMA Yes N/A No3 1GB Simultaneous Live Migrations Unlimited4 N/A 4 10GB Simultaneous Live Migrations Unlimited4 N/A 8 Automated Live Migrations (Load) Yes (VMM) N/A Yes (DRS) Automated Live Migrations (Power) Yes (VMM) N/A Yes (DPM) Live Storage Migration Yes No5 Yes6 Shared Nothing Live Migration Yes No Yes2
  9. 9. Capability Hyper-V (2012 R2) vSphere Hypervisor vSphere 5.5 Ent+ Integrated High Availability Yes No3 Yes4 Failover Prioritization Yes N/A Yes6 Affinity Rules Yes N/A Yes6 NIC Teaming Yes Yes Yes Guest OS Application Monitoring Yes N/A No5 Cluster-Aware Updating Yes N/A Yes6
  10. 10. Replication configured from primary to secondaryReplication can be enabled on the 1st replica to a 3rd site • Once a VM has been successfully replicated to the replica site, replica can be replicated to a 3rd location • Chained Replication • Extended Replica contents match the original replication contents • Extended Replica replication frequencies can differ from original replica • Useful for scenarios such as SMB -> Service Provider -> Service Provider DR Site Replicate to 3rd Location for Extra Level of Resiliency
  11. 11. Capability Hyper-V (2012 R2) vSphere Hypervisor vSphere 5.1 Ent+ Incremental Backup Yes No1 Yes1 Inbox VM Replication Yes No1 Yes1 Replication Capability Hyper-V Replica (R2) vSphere Replication Architecture Inbox with Hypervisor Virtual Appliance Replication Type Asynchronous Asynchronous RTO 30 secs, 5 mins, 15 mins 15 Minutes Replication Tertiary Secondary Planned Failover Yes No Unplanned Failover Yes Yes Test Failover Yes No Simple Failback Process Yes No Automatic Re-IP Address Yes No Point in Time Recovery Yes, 15 points No Orchestration Yes, PowerShell, HVRM No, SRM
  12. 12. Hva er ikke så bra?  Virtual Machine Manager – Støtter ikke alle funksjonalitet  Det er litt annerledes så regn på en transisjonskost  V2V fra VMware til Hyper-V
