The Microsoft hypervisor must have at least one parent (or root partition) running Windows Server 2008 64-bit Edition or Windows Server 2008 R2. Continue reading
Exam 70–659 Revision Notes — Module 1
It’s now only 1 week until I sit my 70–659 Server Virtualization exam, so I really need to start gathering all of these articles together.
First module out of the way, five more to go.…..

The iscsicli.exe Command
iscsicli.exe is the command line interface for the Microsoft iSCSI Software Initiator and can be used to configure and login to iSCSI target devices.
In the full versions of Windows Server 2008 R2 everything can be performed using the GUI, however in the Server Core version, the iscsicli.exe command must be used. Continue reading

Microsoft Multipath I/O (MPIO)
The Microsoft Multipath I/O (MPIO) framework provides multiple paths for read and write functions to your storage device and is built into Windows Server 2008 R2.
MPIO provides redundant failover and load-balancing support for disks or LUNs. The multiple paths can also be aggregated to increase bandwidth for improved performance.
MPIO is protocol independent and can be used with Fiber Channel (FC), iSCSI. parallel SCSI and Serial Attached SCSI (SAS). Continue reading

Hyper-V Storage
Planning for Disks and Storage
Hyper-V host computers can use:
- Direct attached storage (DAS)
- Storage Area Networks (SAN)
- Required for Failover Clustering, so all nodes can access a disk
- Host Clustering: Fibre Channel, FCoE, Serial-Attached SCSI (SAS), iSCSI
- Guest Clustering: iSCSI

Hyper-V VLANs
A VLAN ID is the integer which uniquely identifies a node as belonging to a particular VLAN. As per the 802.1Q specification, the VLAN ID itself is encapsulated within the Ethernet frame, which is how multiple VMs using the same physical NIC can communication on different VLANs simultaneously.

MAC Address Spoofing in Hyper-V
Before you can use Windows NLB (Network Load Balancing) within Hyper-V Virtual Machines, you must enable MAC Address spoofing.
To enable spoofing of MAC Addresses open the Hyper-V management console. Make sure the VM is stopped open the properties of the VM.
Select the Network Adaptor for the NLB VM and check the “Enable spoofing of MAC Address” and click OK. Then start the VM.
Hyper-V MAC Addresses
When a new virtual machine is created, the MAC address for it is either taken from a MAC address pool on the Hyper-V server or from the SCVMM server.

Virtual Networks
Virtual Network Manager (available from the Hyper-V Manager snap-in) offers three types of virtual networks that you can use to define various networking topologies for virtual machines and the virtualization server.

VMM Firewall Ports
When you install the System Center Virtual Machine Manager (VMM) server, you can assign some of the ports that it will use for communications and file transfers between the VMM components.
While it is a best security practice to change the default ports, not all of the ports can be changed through VMM.
