Good afternoon.
My name is Shinya Horiuchi.
I am from Network Service And Technologies

I am here to make a presentation about some datacenters technology.
This will help you to understand the current trends concerning
datacenters.

The term DataCenter includes a myriad of concepts.
So I have divided my talk into three noteworthy parts:
First is Fibre channel over ethernet known as FCoE.
Then I'll present trend of cooling method for datacenter.
And finally, I'll outline what are the MPLS-TP .It is a kind of network
protocol.

That's the agenda. So let's get started.

-------------------------------

Firstly I will talk about FCoE.
What is a FCoE.

The answer is a name of technology that exchange Fibre Channel frames
over Ethernet networks.
In datacenter ,network can be separated into two types of network.

The first network is to communicate with other computer.
It is network that we use to email or surf the internet.
The second network is to store and retrieve a mass of data that is in
storage.
We are usually not aware of this kinds of network .
It works behind the scenes.

Recently , more and more data and communication are treated in
datacenter.
It also means that the number of cables transfering those information
drastically swell.
Code overrun like spaghetti and network equipment's surface covered with
connector.
Because of limited space of datacenter ,this have been considerable
problem.
Those situation also impede smooth repair and maintenance.

Then FCoE is proposed.
It realize integration of those two type of network and it will save
spaces.
Integration of network that carried FC and Ethernet must be reduction of
connector and code.
FCoE is relatively new technology and some organization are addressing
standardization now.

FCoE are realized by basic technology that is Converged Enhanced Network.
It is abbreviated to CEE.
Someday in the future , FCoE become standard like ethernet.



----------------------------------

Secondly , you engineers should notice trend of cooling method for
datacenter.

Nowdays , Free Cooling is increasingly adopted.
Meaning of Free Cooling is to cool down datacenter by utilization of external air
and some natural sources.
External air are used to cool coolant water down .
And that coolant water are used to cool equipment.

Or the air are sometimes directly introduced into datacenter.
Due to requirement of low temperature , datacenter have often been build
in cold region.

And there are another technical trend.
It is called hybrid cooling system.
Previously, cooling equipment is installed along wall of floor and cool
the whole floor down.
But in these days ,density of equipment have increasingly grown.
To cool down efficiently , cooling system's target have been focused on more narrow space.
Hybrid cooling systems are ususaly installed top of racks or along the line of racks.


-------------------------------------------------------

Finally , I would like to speak of a network protocol that is utilized
in datacenter.
It is called MPLS-TP.

In the past , WAN or wide area network user demands reliability rather
than bandwidth of network.
As compared with a decade ago, now bandwidth is also required for WAN ,
because of rich contents.
So network infrastructure steadily shifted from lease line to physically
shared line that is more fast and cheap.

While lease line's reliability is very high , shared line have
relatively lower reliability.
MPLS-TP will make up for that shortcomings and can integrate legacy
equipments into new one's.

One reason for that is architecture that protocol can adopt.
Traditionally, each network routers and switches have information of
route control.
They decide best path by themselves ,but it could lead to trouble of
entire network.
In contrast, MPLS-TP can manage information of route control
comprehensively by center router.

And MPLS-TP also include mechanism that can change over circuit
at once.
Those mechanism have been included regacy technology , but newer WAN protocol
including IP and ethernet don't have those mechanism.
Also ,the same can be said for OAM function (operation administration
and management) that detect circuit trouble immediately.


---------------------------------------------------------

In conclusion, as we have seen , there are some trends of datacenters.
FCoE will be reduce required space inside of datacenter.
And it must be prevail.

Free cooling and hybrid cooling will be boost efficency of datacenter cooling.
Also it leads to cutback in some kind of cost.

MPLS-TP will make an improvement of availability of useful systems.
At the same time, it will make fee of cloud service cheeper.

Thank you for your time and attention.
If you have any quesitions, I'd be happy tro take them.

Good afternoon.
My name is Shinya Horiuchi.
I am from NSAT .
And I mainly in charge of dispersing the expertise of new network equipment to our maintenance staff.
Today I am here to make a presentation about some datacenters technologies.

Because you are responsible for repairing network equipment and new product is marketed day by day, this will help you to understand the current trends concerning data centers.
Then you will effectively make yourself master of new products.

But the term Data Center includes a myriad of concepts.
So I have divided my talk into three parts:
First, I’ll cover what datacenter is.
Then, I’ll present challenges which datacenters face.
And finally, I’ll cover some of the new technologies that can solve those problems.

So that’s the agenda. Let’s begin.

----------------
Firstly I will talk about what is datacenter?
The answer is a facility equipped with or connected to one or more computers, used for processing or transmitting data.
That is a basic principle of data center.
But to understand data center correctly, we have to follow the data center history.
Because form of data center have been changing last few decades.

In the past, huge computers were in computer rooms of each company.
But during the dotcom bubble in the late 1990s, a mass of company require non-stop operation of system and more fast internet connectivity.
And small company were not capable of maintain environment that can fulfill those demands.
Then some companies began building very large facilities , and providing rental service of their data center.

Now, industry of datacenter has grown significantly. And the scale of data center has also shown considerable expansion. Because of this momentum, some problems have emerged. And that trend affects the form of data center.
--------------------------------------------
Let’s move on to the next theme.
What kind of challenges have modern datacenters now faced?

Lately, organizations all around the world began pay attention to global warming. It coupled with the fact that data center operation has tended to expend a great amount of electricity, owners and users of datacenter cannot ignore environmental effect.
Simple expansion is no longer acceptable, given the current data center’s greenhouse gas emission.

Next problem is related to space.
With an expansion of the scale of IT system, datacenter have run out of spaces that store the cable. Storage area network could curtail the number of storage device and virtualization will reduce the number of servers. But code and connector will be rampant continuously.
It is more than just a mess.

Last problem is user’s requirement for availability.
Nowadays, IT operations are a crucial aspect of most organizational operations more than ever. Even if they became victim of devastating disaster, they have to continue their operation.
This fact require careful planning for the component of data center as well as location and design of building.
Additionally, novel concept have been introduced. I’ll explain about this idea later.

-----------------------------------------------------------
Turn to the next subject.
We know there are some problems. But, are there any solutions? The answer is yes.
To address those problems, some new technologies have been introduced to data center.

In concert with concern of global warming , IT devices have gradually became more efficient regarding the usage of energy. And some energy-consuming device will be replaced with a more efficient device.
For example, Solid-state drives typically have lower power consumption than HDDs. And it becomes an active area of research.
And new cooling methods are introduced to datacenter.
For instance free cooling method take advantage of external air to cool coolant water. It must be help to reduce energy consumption.

Also, space problems will be addressed.
The technology that is called FCoE , can solve the problem related to space. There are two types of network in datacenter. One exclusively carries data of storage device, and another NW transfer any other data. FCoE can integrate those two different networks and reduce the number of cable.



To keep availability high, nowadays datacenter fortify their redundancy.
Of course, parts of device and device itself have redundancy for continuously operation. Besides these trends, now datacenters have backup themselves.
Advanced technologies can switch from primary datacenter to secondary datacenter.
For example, company operates their system in Tokyo datacenter.
When devastating earth quake hit the Tokyo, then the company can switch the system to Osaka and operate the system in Osaka.
That is called disaster recovery.
---------------------------------------------------------------

As we have seen , IT innovation affect datacenter’s situation dramatically.
Some changes pose a host of issues to datacenter. And requirement of datacenter become complicated.
As new technologies have came up , we have to learn about those technologies as IT engineer.
But it may be interesting and funny, I hope. I also believe that those moves must bring us a profit, If we can make these aspect chance.

That’s it for my presentation.
Thank you very much for your time and attention.
If you have any question , I’ll be happy to answer.

Onepiece is the bestselling manga in japan.
Almost 200 million copies have already been sold in total.
It is sold almost 200 million copies.

But I have didn't buy that magazine, and always browse , stood and read in convenience stores.



In Golden Week holidays , I went matchmaking party what is called GOUKON.
I am hit it off with a 30-year-old girl.
And We exchange cellular number and e-mail address each other.

This is where the story gets tragic.
Yesterday , I created mail with great pains, struggled to text
to ask her out to dinner.
( I don't always use emoji.pictogram for cellular phone.)

I wait her reply with high expectation.
And then I received a reply that say She have a boyfriend now.

It is my golden week .

People who don't have money wouldn't like to retire.
Usually , japanese people retire at age 60.
But Some company continue their employment.
Set standard and choose people who should work.
Actually I don't know my company's rules and regulations.

Focus more positive reason.
Those who like their job ,probably want to go on.
They will think thier job is satisfying and worth the work.
Company often welcome those intension.
To keep competitive edge , veteran's experience and skill will be valuable.

Some people are eager to retire.
I desire to quit job if I can do.
I am not suitable for, cut out for daily worker ,
I would like to sleep soundly to noon, and read books without anxiety for future.
But I certainlly have anxiety for future.
So I must work.

Older worker have knowledge and know-how, but less enegeric

Mentor is an experienced person who advises and helps a less experienced person.
He is kind of mentor I have.
He love me.

As of now I am blessed mentor's teaching , I prone to learn thing by myself.
It is true that pain and burden help fixiing of ability, however it is time-consuming.

Good afternoon.
My name is Shinya Horiuchi.
I am from Network Service And Technologies

I am here to make a presentation about Datacenter.
This would help you to figure out current trend of Datacenter.

DataCenter includes myriad of concepts.
So I divided my talk into three parts.
I'm going to start with a look at/First is background of datacenter.
Then I'll present/Next is significant changes of the environment for
datacenter
And finally, I'll outline what are the /And finally I will state report
trend and requirement of modern datacenter.

That's the agenda.So let's get started.

-------------------------------


Firstly I will talk about background of datacenter.
What is a datacenter?
The answer is Datacenter , which is often abbreviated as DC , means a
facility equipped with or connected to one or more computers, used for
processing or transmitting data.

In the past, huge computers were in computer rooms of each company.
But during the dotcom bubble in the late 1990s , as online service
prevail , a bunch of company require non-stop operation of system and
more fast internet connectivity.
Naturally it was hard for small companies to establish facility that
acquire those attribute.
Then some companies had an eye on those demands, and began building very
large facilities , and providing rental service of their data center.
Because of that trend , scale of operation and range of solutions became
bigger and wider .
And datacenter experience very simple growing.


--------------------------------------
But surroundings of datacenter have changed with times.
And requirement is more complicated.
So , secondly , I would like to talk about those changes.
What changes should we watch particularly.

The ansawer is three perspectives.
Those are global environment , present business scene and
security of information ,especially for personal information.

Nowdays IT operations are a crucial aspect of most organizational
operations more than ever.
Almost all company can't stop their internal and external service any
more. Even if they become victom of devastating disaster.
This trends create a buzzword "Disaster Recovery"

And lately , organization all around the world began keeping an eye on
global warming.
It coupled with the fact that data center operation have tend to expend a great amount of
electricity , owners and users of datacenter cannot ignore environmental effect.

Besides there are some data.
Given a business as usual scenario greenhouse gas emissions from data
centers is projected to more than double from 2007 levels by 2020.
It means this matter will get worse and worse another decade.

Moreover, public concern about the protection of personal information
is growing.
Leak of that kind of information will be big blow for company.
Those impact can cost several million of dollars for the company.


------------------------------------------------

To address those problem , requirement for datacenter have been changing.
All of compornent of datacenter , including server computer , electrical equipment and datacenter itself , have redunduncy.


To fulfill these requirement ,there is still a lot of development being
done in data center design.
