Hyper-V changes in R2 Live Migration Dynamic virtual machine storage Improved VHD performance Hyper-V in Enhanced processor Windows Server 2008 R2 support & compatibility Enhanced networking support 8

Cluster Shared Volumes CSV is a feature of Failover Clustering that enables multiple nodes to concurrently access a single shared volume • Reduced number of disks’ logical unit numbers (LUNs) • Better use of disk space • Effortlessly track the paths of VHD files and other files • Fewer CSVs to create a configuration to support clustered virtual machines • No specific hardware requirements • Increased resiliency 9

Reasons for Live Migration Hardware maintenance of physical host Updating physical host operating system Moving virtual machine to a more appropriate host 10

How Live Migration Works Setting up of Live Migration Transferring of memory pages from the source node to the destination node Moving of the storage handle from the source to the destination Resuming of the virtual machine on the destination server Cleaning up of network occurs 11

Direct Access Features of DirectAccess  Connects automatically to corporate network over the public network  Uses various protocols, including HTTPS, to establish IPv6 connectivity  Supports selected server access and IPSec authentication  Supports end-to-end authentication and encryption  Supports management of remote client computers  Allows remote users to connect directly to intranet servers Benefits of DirectAccess  Always-on connectivity  Seamless connectivity  Bidirectional access  Improved security  Integrated solution Direct Access Server 13

How Direct Access Works The DirectAccess client running Windows 7 detects whether it is connected to a network The client attempts to connect to an intranet Web site that is specified during the DirectAccess configuration The client connects to the DirectAccess server using IPv6 and IPSec The DirectAccess client and server authenticate each other by using computer certificates to establish the IPSec session The DirectAccess server verifies that the computer and user are authorized to connect by using DirectAccess The client obtains a health certificate from a Health Registration Authority (HRA) prior to connecting to the DirectAccess server The DirectAccess server begins forwarding traffic from the DirectAccess client to the intranet resources to which the user has been granted access. 14

Name Resolution Policy Table NRPT is a table that defines DNS servers for different namespaces and corresponding security settings. It is used before the adapter’s DNS settings. Using NRPT: • DNS servers can be defined for each DNS namespace rather than for each interface • DNS queries for specific namespaces can be optionally secured by using IPsec 15

How a network access client determines the type of network A network location server (NLS) is an internal network server that hosts an HTTPS-based URL. DirectAccess clients access the URL to determine whether they are located on the intranet or not. START Network change event Yes Can resolve No NLS FQDN? Yes Can No contact NLS Located on Located on public Located on public intranet network network

Client and server requirements Server-side Client-side To deploy DirectAccess, the server To deploy DirectAccess, the client must: must: • Be joined to an Active Directory • Be joined to an Active Directory domain domain • Run Windows Server 2008 R2 • Run Windows 7 Ultimate Edition, Windows 7 Enterprise Edition, or • Have two physical network Windows Server 2008 R2 adapters installed • Have at least two consecutive static public IPv4 addresses 17

Infrastructure requirements PKI DNS and domain controller IPSec policies ICMPv6 ICMPv6 Echo Group Policy Request traffic IPv6 Active Directory IPv6 and transition DirectAccess technologies Server 18

Direct Access Configuration Steps to configure DirectAccess • Install Windows Server 2008 R2 • Join the DirectAccess server to an Active Directory domain • Install the DirectAccess Management feature and configure the DirectAccess server on the perimeter network • Enable ports and protocols needed for DirectAccess in the firewall exceptions • Ensure that you have an IPv4 address available and that you have the ability to have that address published in your externally-facing DNS server • If you have disabled IPv6 on clients and servers, enable IPv6 • Create a security group in Active Directory • Install a Web server on the DirectAccess server • Designate one of the server network adapters as the Internet-facing interface. • On the DirectAccess server, ensure that the Internet-facing interface is configured to be either a Public or a Private interface. • Add and configure the Certificate Authority server role 19

Enhancements for Branch Offices Networking Enhancements • BranchCache • VPN Reconnect • URL-based Quality of Service (QoS) • Multiple active firewall profiles • Transparent caching and background synchronization of offline files Benefits • Read-Only DFS replicas • BitLocker to Go 21

Branch Cache The following are the features of BranchCache: • Reduces the network utilization on WAN connections between branch offices and the head office • Improves the performance of applications that use HTTP, HTTPS, or SMB • Improves the responsiveness of applications across slow WAN links • Enables the client to retrieve data from local BranchCache • Caches only the read requests • Works seamlessly alongside network security technologies 22

Hosted cache vs distributed cache Hosted Cache Distributed Cache Get Get Search Get Search Get Get Offer Get Request Head office Put Branch office 23

Branch Cache Requirements Requirements for using Requirements for distributed and Branch Cache hosted cache modes • Install the BranchCache feature • In the distributed cache mode, or the BranchCache for Network no server is required in the Files feature on the server that is branch office; just Windows 7 or hosting the content Windows Server 2008 R2 clients • Configure clients, either by using are required Group Policy or the netsh • In the hosted cache mode, command Windows Server 2008 R2 server must be configured for BranchCache host in the branch office • The BranchCache host server must have a digital certificate 24

Q&A Questions? Aaron Harclerode • Aaron.harclerode@springhouse.com 29

What is Virtual Desktop Infrastructure Virtual Desktop Infrastructure (VDI) is a centralized desktop delivery architecture, which allows to centralize the storage, execution, and management of Windows desktops Key Benefits of VDI • Access to data and applications from any device • Improved data security and compliance • Simplified management and deployment of applications • Improved business continuity • Integrated management of physical, virtual, and session-based desktops • Centralized data storage and backup Key Deployment Scenarios of VDI are persistent virtual machines and pooled virtual machines 30

Types of VDI Personal virtual desktops Each virtual machine is like a traditional personal computer, where user data, settings, applications, and operating systems are stored, and users have assigned a personal virtual desktop Pooled virtual desktops Identically configured virtual machines are in the pool and users can connect to any of them. After users log off, all changes are discarded, so user data must be stored outside the virtual machine 31

How VDI works A user can connect to a virtual machined based on the VDI configured for: configured for: 1. A user initiates the connection to the personal virtualpool virtual desktop desktop 2. The user sends the request to the RD Session Host server running in redirection mode 3. The RD Session Host server forwards the request to the RD redirects Connection Broker server 4. The RD Connection Broker server queries whether any existing verifies AD DS and retrieves the name of the virtual machine user is assigned to the session exists for the requesting that account requesting user account 5. The RD Session Host server redirects the request to the client 5. The RD Connection Broker server sends a request to the RD computer that initiated the connection Virtualization Host server to start the virtual machine 6. The client computer connects to the virtual desktop pool Personalvirtual desktops Pooled virtual desktops 6. The RD Virtualization Host server returns the IP address of the FQDN to the RD Connection Broker server desktops Pooled virtual 7. The RD Session Host server redirects the request to the client computer that initiated the connection 8. The client computer connects to the personal virtual desktop 32
