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”.

Network Considerations
Customers
• How do I ensure network • Fully Leverage Network
multi-tenancy? Fabric
• IP Address Management is a • How do I integrate with
pain. existing fabric?
• What if VMs are competing • Network Metering?
for bandwidth? • Can I dedicate a NIC to a
workload?

Hybrid Clouds
Windows Server "8" is optimized for Hybrid Clouds to host multi-tenant
workloads

Tenant 1: Multiple VM Workloads


Data Center

Security
In 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 & Isolation

• Isolation Scenario To Internet (10.1.1.1)
• 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)

• Each VM has illusion it is running fabric
as a physical server

Reliability
Even when hardware fails …
… customers want continuous availability

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.

Advanced Network Security
DHCP 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)

SR-IOV Yes DirectPath I/O1 DirectPath I/O1
Storage Encryption Yes No No

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 support
No 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.
