Why Wd Caviar Black Is Best

Why Wd Caviar Black Is Best
Western Digital Corporation is well known for its products. They are known for the quality of their products, for the strength and for the consistency of their products. People buy western digital products just by their name and when it comes to hard drives western digital is a company on which a person can trust by closing eyes as well. Since ages they have never compromised with their quality and retained it as it is Microsoft MCTS Training.

People have no doubts on the product if it is having the label of western digital. Western digital products are easily available in the markets. They believe in doing continues innovations and due to this reason they keep on adding new products in their product lists. They spend a considerable amount of money in their research and development department so as to provide new features to their consumers.

WD caviar black is a popular product of western digital owing to its following features.

Great electronic and strong mechanical architecture.

It has dual processor. This in turn maximizes performance.

Recording head of this hard drive never touches media of the disk due to which recording media and head has less wear. It gives better protection to the drive as well.

WD Caviar Black has a bigger cache up to sixty four MB so as to improve performance.

They are having massive capacity to store a large amount of data.

They are having 2 Terabyte capacities.

WD Caviar Black comes with a warranty of five years.

These hard disk drives are tried and tested many times in their FIT lab. This is done to ensure that western digital hard disk drive will perform well on consumers computers.

It has dual actuator technology.

Motor shaft is present on both ends. This in turn stabilize platters and reduce vibrations that are induced due to system while writing and reading operations.

WD Caviar Black is ideal for all applications including video editing, photo editing and operations related to multimedia.

All the above features are responsible for WD Caviar Black popularity.

A question can come in consumers mind that how western digital drives protect their data. Hard disk drives of western digital are coming up with data lifeguard tools. These data lifeguard tools are the utilities that make hard disk drive installation, repair and diagnostic simple and tension free. Data lifeguard is a feature which is used for data protection. It includes shock protection as well. It finds, detects and isolates problems. Not only this, it tries to repair all the problems that develop on the hard drive over the life time Microsoft MCITP Training.

Shock guard technology protects the disk from damage due to vibrations and bumps when the hard disk is working. It is due to this technology western digital caviar drives are having shock specifications.

So, one can see how much pains western digital is taking to provide a nice, genuine and great product to its consumers. They feel that customer money is important and they should not waste it and should pay full price for their money.

Using IPv6 in Windows Server 2008

Using IPv6 in Windows Server 2008
IPv6 Addresses problems in IPv4

* Automatic Address Configuration – Stateful hosts use DHCPv6. Stateless hosts configure themselves.
* Header Size – Non-essential and optional fields are found in extension headers.
* Routing Table Size – Designed to be more efficient.
* Network Level Security – IPSec is now mandatory.
* Real Time Data Delivery – payload encryption does not affect QoS.
* Removal of Broadcast Traffic – Neighbour discovery replaces ARP broadcasts, ICMPv4, Router Discovery and ICMPv4 redirect messages.
* IPV6 Address Structure
* IPv6 Address Syntax

IPv6 is a 128-address divided into 16-bit boundaries. Each 16 bit block is converted to a 4 bit hex number and colons are used to separate the bits. Leading zeros can be removed and long sequences of zeros can be compressed. For example 21cd:0048:0000:0000:03ac:ae45:8e4c can be expressed as 21cd:48::3ac:ae45:8e4c
IPv6 Address Prefix

Like we do in IPv4 and express subnets as 192.168.12.0/24, we can also do this in IPv6 and would look like 21cd:53::/64
IPv6 Address Types

* Unicast
* Multicast
* Anycast

IPv6 Unicast Addresses

* Global
* Link-Local
* Site-Local
* Special
* Network Service Access Point and Internet Packet Exchange mapped addresses Microsoft MCTS Training

Planning an IPv4 to IPv6 Transition Strategy

Those Strategies include:

* Dual Stack Transition
* Configured Tunneling Transition
* Automatic Tunneling
* 6to4
* Teredo
* Intra-Site Automatic Tunnel Addressing Protocol

Implementing IPv4-to-IPv6 Compatibility

* IPv4 Compatible Address
* IPv4 Mapped Address
* Teredo Address
* ISATAP Addresses

Using IPv6 Tools

Ping works by specifying the IPv6 address. IPconfig /all will show you the IPv6 setting and IPv4 settings. Netsh interface ipv6 – ipv6 added to netsh interface commands specifies the IPv6 stack
Configuring Clients through DHCPv6

Configuring a DHCPv6 scope is very much the same as configuring an IPv4 DHCP scope. Page 87 of the book goes through a great description of configuring DHCPv6. Remember the 80/20 rule.
Planning an IPv6 Network

There are three steps to planning your IPv6 network. First step is to identify and analyze hardware requirements. Look at all the hardware you have and identify if it will all work with IPv6. If not, will you replace this hardware or continue to support the hardware.

The second step is to analyze software and application requirements Microsoft MCITP Certification. Does everything work with IPv6? If not, how will you support these applications?

Finally your last step is to document the requirements. How many sites are there, how should the prefix allocation be delegated, etc. These three steps will take a lot of time but once complete, you can draw up the project plan. Project planning isn’t covered in this lesson.

That’s all for Chapter 2, Lesson 1. There is a lot of information to digest there and for most of us, its relatively new and will take some time work through and understand it. Lesson 2 of the chapter covers Configuring DNS.
