Hey everyone, welcome back to another session by K21 Academy.

大家好，歡迎回到 K21 Academy 的另一場課程。

未來進行式

And today our expert trainer will be discussing about the complete architecture of exadata.

今天我們的專家講師將會深入探討 exadata 的完整架構。

So let's get into the video and watch the video till the end to get all the major insights.

讓我們一起進入影片，並看到最後，以獲得所有重要的見解。

So here what you are going to see is on the exadata side, we are basically providing the exadata public service.

所以在這裡，你會看到在 exadata 部分，我們基本上提供的是 exadata public service。

Okay, if you see here, this is the exadata public service.

好的，如果你在這裡看到，這就是 exadata public service。

But that public service is provided in the customer data center which is Oracle owned and managed infrastructure and that is located in your data center.

但這個 public service 是在客戶資料中心提供的，也就是 Oracle 擁有和管理的基礎設施，而且它就位於你的資料中心。

And now how this is going to be maintained.

So Oracle will give you the exadata infrastructure plus two control plane infrastructure too.

所以 Oracle 會提供你 exadata 基礎設施，還有兩個控制平面基礎設施。

Now this control plane is through which you know, Oracle is also allowing you to connect to the OCI console and see as like what I am seeing is that is when I click the.

現在這個控制平面，透過它，你知道，Oracle 也允許你連接到 OCI 主控臺，並且看到就像我現在看到的，就是當我點擊。

Just a minute, yeah, so when I click this, this is basically the control plane web UI which is installed on the control plane servers.

稍等一下，對，所以當我點擊這個，這基本上就是安裝在控制平面伺服器上的控制平面網頁使用者介面。

And that is where from where I'm going to see.

So Oracle has got the endpoints of the of the exercise service basically in the region specific stuff.

所以 Oracle 在區域特定項目中，基本上擁有該 exercise service 的端點。

Means the endpoints are there and through which the control panel and the control plane from where the entire management my console is there and I can manage it from the GUI based up, right?

這表示端點就在那裡，透過它們，控制面板和控制平面，也就是我整個管理主控臺所在的地方，我可以從圖形使用者介面為基礎來管理它，對嗎？

And through that I am also connected to the service tenancy of Oracle which is via network admin VCN ADMINISTRATOR OF Oracle now here is the management server which is in the VCN admin and this is all basically controlled by Oracle.

並且透過它，我也連接到 Oracle 的服務租戶，也就是透過網路管理員 VCN 管理員 (Oracle)，這裡有管理伺服器，它在 VCN 管理員中，這一切基本上都由 Oracle 控制。

Okay, so Oracle is basically going to connect to this management server from this management server will be performing the task.

好的，所以 Oracle 基本上會從這個管理伺服器連接，並透過這個管理伺服器執行任務。

And you can also access the other services as well from your tenancy.

你也可以從你的租戶存取其他服務。

Like this is say my tenancy is there and I want to connect to access a logging service or maybe the object storage service.

像是，假設這是我的租戶，我想連接存取日誌服務，或者物件儲存服務。

I will be securely connecting and using these services from the Oracle service tenancy.

我會從 Oracle 的服務租戶安全地連線並使用這些服務。

所以，是的，有一個出站通道。

So there is no collection or no, you know, data which Oracle is going to put it in our servers.

所以沒有收集，或者說，Oracle 不會將任何資料放在我們的伺服器上。

They are only going to collect the monitoring and the telemetry data.

他們只會收集監控和遙測資料。

So this is when you see the Oracle exadata infrastructure.

所以這就是當你看到 Oracle exadata 基礎設施的時候。

It is exactly the same which we have seen it in Exacs Dom 0 is there which is an Oracle domain.

這跟我們在 Exacs 中看到的完全一樣，有 Dom 0，這是一個 Oracle 網域。

And then over that the virtual machines, the database servers will be running from your end.

然後在其上，虛擬機器、資料庫伺服器將從你的端點運行。

You can basically access your OCI comes from The OCI console in your tenancy, you will be able to access this exadata infrastructure which is within your, which is within your data center.

你可以從你的租戶存取 OCI 主控臺，你將能夠存取位於你的資料中心的 exadata 基礎設施。

From there you can basically access and perform all the operations which are under your control.

從那裡，你基本上可以存取並執行所有在你控制之下的操作。

Apart from that via cli, you can also perform it, you can connect it and you can perform via REST APIs.

除了透過 CLI 之外，你也可以執行，你可以連接它，然後透過 REST API 執行。

So there are rich APIs which are available through which you will be able to update and perform all the stuff which you are going.

所以有豐富的 API 可供使用，透過這些 API，你將能夠更新並執行你將要做的所有事情。

You can do it from the console and the clis.

所以如果我們從網路方面來看。

So we basically has the virtual machines which is running.

所以我們基本上有正在運行的虛擬機器。

So these are like your database servers or you know, the, sorry, these are your clusters, VM clusters and these clusters.

所以這些就像是你的資料庫伺服器，或者你知道的，抱歉，這些是你的叢集，VM 叢集，而這些叢集。

So when I say talk about the database server, it is the virtual machine.

所以當我說資料庫伺服器時，它就是虛擬機器。

Let me show you from the console how it looks like.

我從主控臺給你們看看實際樣子。

And when I click the cluster, it is going to take me here.

然後當我點進叢集，就會帶我到這裡。

Now if you see here, these are the virtual machines.

現在你們看這裡，這些就是虛擬機器。

So these are like my four database servers which are running.

所以這些就像是我正在運行的四臺資料庫伺服器。

And these are like four node clusters on which your database servers will be later database will be further created.

然後這就像是四節點叢集，你們的資料庫伺服器之後會在上面進一步建立資料庫。

And see if you see here, over these virtual machines, my database servers will be hosted.

然後你們看這裡，在這些虛擬機器上面，就會託管我的資料庫伺服器。

So it can host up to eight virtual machines per database server.

所以它每個資料庫伺服器最多可以託管八個虛擬機器。

At the back end there is a storage cell is there three.

後端有一個儲存單元，有三個。

And the management network is going to be there through which these cells will be maintained.

而管理網路將會透過它來維護這些單元。

At the top, if you are seeing the same, you know, which we have seen it last time as well, the client network and the backup network.

在最上面，如果你們看到一樣的東西，就像我們上次看到的，客戶網路和備份網路。

So client network is basically the one which is, you know, used for the client access to these database server.

所以客戶網路基本上就是用來讓客戶存取這些資料庫伺服器的。

And like from your application, when you want to connect to the database server, this is the network which is going to be used.

而且就像從你的應用程式，當你想連接到資料庫伺服器時，這個網路就會被使用。

And similar to the client access network, you have got the, you know, backup network as well, which can be used for your backups and for your bulk data transfer if you want to do it.

和客戶存取網路類似，你們也有備份網路，可以用來進行備份以及你想要的批量資料傳輸。

So Oracle basically recommends that, you know, you should use the backup network for your backup specifically so that it can be, you know, it's a heavy operation.

所以 Oracle 基本上建議，你們應該特別使用備份網路來進行備份，因為這是一個比較耗費資源的操作。

So it should not hinder or affect the other operation, other activities in the client network.

所以這不會阻礙或影響客戶網路中的其他操作、其他活動。

So that is the reason the two networks are separate and there.

這就是為什麼這兩個網路是分開的。

Now if I say talk about the client plane network, sorry, the control plane network, which is nothing but got the, you know, VPN which connects basically the two control plane servers which are located at the exadata cloud at customer rack to the Oracle cloud infrastructure.

現在，如果我說談論客戶平面網路，抱歉，是控制平面網路，它基本上就是透過 VPN 連接位於客戶機架上的 exadata 雲端與 Oracle 雲端基礎設施之間的兩個控制平面伺服器。

So that connectivity is what is provided.

所以這個連線就是這樣提供的。

So it is basically used for your monitoring and the administration of your exadata clouded customer by Oracle.

所以它基本上是用來讓 Oracle 監控和管理你們的 exadata 客戶端。

So this administration, this network basically connects your EXA CC servers and your switches to the two control panels.

所以這個管理網路基本上會連接你們的 EXA CC 伺服器和交換機到兩個控制面板。

So two control panels, control plane will be.

所以會有兩個控制面板，控制平面。

Servers will be located here, right, cps.

So the admin network basically connects that.

所以管理網路基本上連接了那個。

Yeah, There is an InfiniBand server, I think.

對，我認為有一個 InfiniBand 伺服器。

Yeah, here it is the back network fabric.

So this network basically connects your database server and the storage server and the control plane servers.

所以這個網路基本上連接了你們的資料庫伺服器、儲存伺服器和控制平面伺服器。

So this basically uses the InfiniBand switches which now will be replaced with the row switches in the X8 and the X9.

所以這基本上是使用 InfiniBand 交換器，現在在 X8 和 X9 中將會被 row 交換器取代。

This is a insight look about the users, the keys, your 9M.

這是使用者、金鑰、你的 9M 的深入瞭解。

So if you see here, this is your DOM0 the last border.

所以如果你看到這裡，這是你的 DOM0，最後的邊界。

And in that you have the DOM view which has got your management tools, access CLI and the D bus CLI it has got users OPC, Oracle Grid Root.

然後裡面有 DOM 視圖，裡面有你的管理工具、存取 CLI 和 D bus CLI，裡面有使用者 OPC、Oracle Grid Root。

You are connected via key with the OPC and then you will be having a sudo access to your database dom you.

你透過金鑰連接到 OPC，然後你將擁有 sudo 權限存取你的資料庫 dom。

So guys, this was our expert from Team K21 Academy.

所以各位，這就是我們 K21 Academy 團隊的專家。
