DEPOLYING ROLES TO VHD’S

(Total Explanation)

Install Role while offline. In a Enterprise the administrator maintains VM. Add a role to a virtual HDD while offline. Can get there from server manager. In enterprise version most admins will maintain VM in Offline State. Selects VHD file.

Allows us to install a role. We can install many servers. On local and 10 others at the same time.

Strips data, in 64k chunks, and parity blocks across all of the disks. Write-Write-Parity. To make sure the block and its parity information are not stored on the same disk.

After the install of physical disk, you can catencate the spaces together in a storage pool. Then create a virtual disk any size.

Strip volume: The system writes data one strip at a time to each success disk one the volume. Example Drive C, D. Striped. 64k and 64k simultaneously on each drive. Span 64k on 1st, then when there is no room, goes to the next drive. Fill and go to next. Neither has fault tolerance. Strip slow, Span faster. Mirror the 64k chunks are identical. 

Support 2 types of folder shares. Server message blocks andNFS. Also access base enumeration. This prevents users from seeing files and folders they don’t have permission to access. Hidden share by file$. Have to map manually.

Combination of allowed and denied permissions. The security principal receives for a given system element. Explicit permissions are expressly given. Implicit (implied) permissions are inherited. Effective permission is the most restrictive.  Share levels only work across the network. Give everyone control over share, then NTFS.

Print device is the hardware. Print servers are what you install, the software. Software talks to the print device. Print pool are the physical devices (2 minimum).

Is based on the hypervisor module. Also called the Virtual Machine monitor. Hypervisor abstracts the physical hardware and creates multiple virtual hardware configurations. All virtual machines. The hypervisor creates a Virtual environment. Also creates individual environments called partitions. Each partition has its own Operating System and accesses the hardware via the hypervisor. Type II Virtualization is put host underneath. The host operates. Type I, puts the hypervisor. Type I does not rely on the host for access to the hardware. Each bloc are called child partitions. Type 1 loads hypervisor before the parent O/S. When we install a guest OS on child partition, it may not function properly n the OS that is there. Install guest integration services which allows the compatibility.

Type II Virtualization puts a host OS underneath and the host OS hosts the virtual ones on top of that. Type I puts hypervisor on top of hardware with the OS on top of that. Parent O/S. Type I does not rely on host to access to hardware. Loads Hypervisor first, then the parent OS.

When we install a guest OS on child partition. It may not function in the OS environment that is currently there. Install guest integration services. Allows the compatibility to occur.

Enables to you preserve an existing virtual disk image in its original state. Take a snap shot of original set up and keep that pristine. We can reset.

Type of virtual disk that points to the physical disk itself on the host computer. Virtual to host.

You can create any time. It is a file. You don’t have to add to a virtual machine. Do this via new virtual hard disk wizard in the Hyper-V manager

Virtual networking architecture. Virtual network cards, then switches. External network switch that because it provides connections external to the Hyper-V environment. Take the virtual and create to the real world. Allows sit to hook to real world. Preferred arrangement in production environments

Network cards have MAC addresses. They work with switches. In real network, there are MAC Addresses. Macs work with switches. We don’t have a real card and we need to create one. First 3 bytes 25 bits of mac range- always 00.15.5D, which is OUI, Organizational Unique Identifier, registered by Microsoft, 4-5 bytes are the last 2 bytes of the IP address, assignment to physical adapter in HEX, the last 6th byte contains a value from FF up to 256 possible addressees. How they get to 48 bits total.

CIDR. Subnetting method that allows you to place the division between the network bits. The line in the sand. Wherever it has to be. The ones on the dots are classful interdomain routing.

A, B and C.

D and E are not used for networks. 

We have Mixed networks, IPv4 and IPv6. Problem is sending IP6 info. We need to Encapsulate. There are 2 methods to encapsulate, do a IP Config /all we see we have both IP4 and IP6 configurations. Card is sending IP4 and IP6 packets. Dual Stack Environment. It can connect to any IP6 or IP4 device. By doing so we don’t have to encapsulate. But on the internet we can’t encapsulate. We use 6 to 4. Incorporates the IP4 connections of the network into the IP6 infrastructure. Take the IP4 addresses and express them in IP6 format, then encapsulate take the 6 traffic in the 4 packet.

calculate the storage capacity of raid 5 

Count the loss. 1/number of drives. Loose this much storage capacity.

 Dual Stack Environment

1. How do we see it

2. What is it

With Dual Stack Environment we.......

 can connect to any IP6 or IP4 device. Don’t have to encapsulate.

Can we Encapsulate on the Internet?

No. We use 6 to 4

We have Mixed networks, IPv4 and IPv6. Problem is sending IP6 info. We need to Encapsulate. There are 2 methods

Other than User and Drive limitations with Windows Server R2 Essentials, what is the other limitation?

• Does not include Active Directory lightweight service

With WINDOWS SERVER R2 ESSENTIALS EDITION

What kind of directory Service is provided? 

• Is a lightweight directory service

DEPOLYING ROLES TO VHD’S

What must be the case to add a role

across the network.

Hypervisor abstracts the physical hardware and creates multiple virtual hardware configurations.

The hypervisor creates a Virtual environment. Also creates individual environments called partitions.
