Session Objectives and Takeaways

• Why Windows Server "8" Hyper-V for Private Cloud• What did we learn from you and our Partners?

• Networking

• Hyper-V VM Mobility

• Critical Cloud Security

• Hyper-V Replica

The Definitive Platform for Cloud:

Windows Server “8”.

Windows Server "8" Networking

Network ConsiderationsCustomers

• How do I ensure network multi-tenancy?

• IP Address Management is a pain.

• What if VMs are competing for bandwidth?

• Fully Leverage Network Fabric

• How do I integrate with existing fabric?

• Network Metering?• Can I dedicate a NIC to a

workload?

Hybrid CloudsWindows Server "8" is optimized for Hybrid Clouds to host multi-

tenant workloads

Tenant 2: Multiple VM Workloads

Data Center


SecurityIn a multi-tenant environment …

… customers want security and isolation


Data Center


Multi-Tenant Network Requirements• Tenant wants to easily move VMs to/from the cloud

• Hoster wants to place VMs anywhere in the data center

• Both want: Easy Onboarding, Flexibility & IsolationCloud Data

Woodgrove BankBlue 10.1.0.0/16

Contoso BankRed 10.1.0.0/16

One Solution: PVLAN

• Isolation Scenario• Hoster wants to isolate all VMs from each other and allow internet connectivity

• #1 Customer Ask from hosters

• Community Scenario• Hoster wants tenant VMs to interact with each other but not with other tenant VMs

• Requires a VLAN id for each “community” (limited scalability, only 4095 VLAN IDs)

Windows Filter Platform (WFP) Extensions can inspect, drop, modify, and insert packets using WFP APIs

Windows Antivirus and Firewall software uses WFP for traffic filtering

Example: Virtual Firewall by 5NINE Software

Filtering extensions can also be implemented using NDIS filtering APIs

Example: VM DoS Prevention by Broadcom

Forwarding extensions direct traffic, defining the destination(s) of each packet

Cloud Admins Want Scale, Customers PerfDVMQ, IPsec Task Offload, SR-IOV

IPsec Task Offload: Microsoft expects deployment of Internet Protocol security (IPsec) to increase significantly in the coming years. The large demands placed on the CPU by the IPsec integrity and encryption algorithms can reduce the performance of your network connections. IPsec Task Offload is a technology built into the Windows operating system that moves this workload from the main computer's CPU to a dedicated processor on the network adapter.

SR-IOV is a specification that allows a PCIe device to appear to be multiple separate physical PCIe devices. The SR-IOV specification was created and is maintained by the PCI SIG, with the idea that a standard specification will help promote interoperability. SR-IOV works by introducing the idea of physical functions (PFs) and virtual functions (VFs). Physical functions (PFs) are full-featured PCIe functions; virtual functions (VFs) are “lightweight” functions that lack configuration resources.

Dynamic Virtual Machine Queue (VMQ) is a feature available to computers running Windows Server 2008 R2 with the Hyper-V server role installed, that have VMQ-capable network hardware. VMQ uses hardware packet filtering to deliver packet data from an external virtual machine network directly to virtual machines, which reduces the overhead of routing packets and copying them from the management operating system to the virtual machine.

Advanced Network SecurityDHCP Guard, Router Guard, Monitor Port

• DHCP Guard is a security feature that drops DHCP server messages from unauthorized virtual machines pretending to be DHCP servers.

• Router Guard is a security feature that drops Router Advertisement and Redirection messages from unauthorized virtual machines pretending to be routers.

• Monitor Mode duplicates all egress and ingress traffic to/from one or more switch ports (being monitored) to another switch port (performing monitoring)

Manage to a Service Level AgreementNetwork Bandwidth & QoS

• Bandwidth Management allows you to easily reserve minimum or set maximums to provide QoS controls to manage to a service level agreement

1. DirectPath IO, whilst not identical to SR-IOV, aims to provide virtual machines with more direct access to hardware devices, with network cards being a good example. Whilst on the surface, this will boost VM networking performance, and reduce the burden on host CPU cycles, in reality, there are a number of caveats in using DirectPath I/O:• Very small Hardware Compatibility List• No Memory Overcommit• No vMotion (unless running certain configurations of Cisco UCS)• No Fault Tolerance• No Network I/O Control• No VM Snapshots (unless running certain configurations of Cisco UCS)• No Suspend/Resume (unless running certain configurations of Cisco UCS)• No VMsafe/Endpoint Security supportNo such restrictions are imposed when using SR-IOV, ensuring customers can combine the highest levels of performance with the flexibility they need for an agile infrastructure.

Wouldn’t it be great if you could Live Migrate a VM with nothing but an

Ethernet cable?We think so too…

Introducing: Share Nothing Live Migration

VM MobilityComplete mobility. Simply the best.

• Live Migration with High Availability• Live Migrate among servers in a failover cluster

• SMB Live Migration• Live Migrate VMs among servers with SMB storage
