1 General

1.1 Document Objectives

Aims of this document are to provide a basic knowledge on how to create and manage Datastore, Virtual Switch and Virtual Machine the ESXi Machine.

1.2 Reference

Vmware Support

2 Connect to the ESXi Server:

2.1 Which tool to use to manage ESXi Server

To manage the ESXi Server, you have to use Vsphere client software. You could download it or from the Vmware website (see Reference for the URL) and look for the Vsphere client in the ESXi 4.1 support download link if you have an internet access, or from the ESXi server itself. For the second solution, open a web browser like Mozilla or internet explorer and go on the ESXi IP@. For example it’s could be like the following: https://172.16.41.100. You will have after certificate confirmation request a page where you will see a link to download Vsphere Client.

2.2 Start with Vsphere Client

Launch the Vsphere client from your windows menu. You will have the following login popup window:

You will obtain the following management windows:

2.3 First things to do after ESXi installation

2.3.1 Manage Virtual Switch

To access to the Virtual Switch settings, click on the “Configuration” tab. And Select Network Adapter first to check that you are able to see all of the physical installed network board.

After this, select Networking to access on the Virtual Switch view and settings.

Depend on the number of physical NIC Board you have you could create or a simple virtual switch or more complex virtual switch.

The example show before is coming from the lab ESXI Server. There is 2 Physical Nic board. + Nic board is used for the internet access vmnic0 and connected only to the Proxy server, and another NIC vmnic1 shared for ESXi remote console administration and all virtual machine.

If you click on Properties link of the NIC board that you have to mange you will have a new windows called Vswitchx (where x is the number of the Vswitch) in our case we have Vswitch0 and Vswitch1. Vswitch0 is for internet access and Vswitch 1 is for remote management and virtual server.

On the previous screenshots, you will see 3 options. The third 1 call VMKernel2 is important as it’s from this access that we could manage remotely with Vsphere the ESXi. This interface will have an IP@ set who is the 1 provide during the ESXi installation. Never delete this configuration if there is no other 1 or you will lose the remote managed access (Fig 2.3.1.A to 2.3.1.E). The second option is the Virtual Machine port Group (Figure 2.3.1.F to 2.3.1.I). These allow managing Nat for all Virtual Machine. No setting is really needed on this part. The first option concerns the Vswitch (Fig 2.3.1.J to 2.3.1.M). This Vswitch is a virtual switch and have the same usage than a physical switch.

Figure 2.3.1.M

In the Figure 2.3.1.J, you could set the number of port. 1 port is equal to 1 NIC card. In Figure 2.3.1.M, in case where there is different Physical Nic Board, you could select if they should be connected (Active area) or Standby for redundancy or unused.

2.3.2 Adding a new Vswitch

To install a new Vswitch, click on add Networking link (Fig 2.3.2 A) and the window show in Fig 2.3.2 B will open.

Figure 2.3.2.N

Figure 2.3.2.O

The first Selection will depend on which usage you will have for the Vswitch and depend of course of the complexity of your design. In general on Stand alone design, the Vswitch is quite simple. Also, if you need the both option, this could be add later via the properties setting of the added Vswitch, selecting the missing option and as it will be show on the next windows (Fig. 2.3.2.C) you will have the possibility or to create a new Vswitch, or select an existing Vswitch. For now, Select create a new switch and click next.

Figure 2.3.2.P

Provide the best description name for the new Virtual Network, Provide VLAN ID if necessary and click on next button. (Fig. 2.3.2D)

2.3.3 Changing properties of a virtual switch

To change a Vswitch setting, go on the desired Vswitch (Vswitch2 in our example) and click on the properties button as shown in figure 2.3.3.A

Figure 2.3.3.S

The following windows will appear (Fig 2.3.3.B). Click on Add button for example if you need to add the VMkernel option, select VMkernel and click on Next button.

Figure 2.3.3.T

Provide the most appropriated name for the label; check Vmotion and management Traffic case (Fig 2.3.3.C) then click Next.

Figure 2.3.3.U

Select the way on how to receiver the IP@ for this virtual Vswitch, DHCP or Manually. If manual, provide correct information. Then click on next. (Fig. 2.3.3.D) and finish by clicking on Finish Button.

2.3.4 Datastorage Management

2.3.4.1 Create the datastore

Rq:For this part as there is no available hard disk drive on the server a Freenas server has to be installed to allow to add an iSCSI connector with the ESXi Server to have a new hard disk drive found like a local disk same if it’s a remote 1 connected via the network. As this part is not the topic of this doc, but in case where it’s need go to link 1 for downloading and installing Freenas OS (recommended to install it on a 2Gb min USB key) and go to link 2 for the setting of the iSCSI device on the Freenas and connection with the ESXi Server.

Link1:http://www.freenas.org/Link2:http://www.vladan.fr/how-to-configure-freenas-8-for-iscsi-and-connect-to-esxi/

To proceed on the Datastore creation, in configuration Tab, click on Storage link. From this page, click on “Add Storage” as shown in Fig 2.3.4.A

Figure 2.3.4.W

Following window will open:

Figure 2.3.4.X

Let’s default selection and click on next button. Select the desired drive and click next (Fig. 2.3.4.C)

Figure 2.3.4.Y

Disk information will appear. Click next to confirm the creation. This process will destroy al data present on the disk if there is. (Fig: 2.3.4.D)

Figure 2.3.4.Z

Provide an explicit Datastore name and click on Next. (Fig: 2.3.4.E)

Figure 2.3.4.AA

Depend on the size of the disk, select the correct block size to optimize the capacity and let’s by default the Maximize Capacity check. (Fig: 2.3.4.F and 2.3.4.G) then click next.

Figure 2.3.4.AB

Figure 2.3.4.AC

The last step is a resume of the previous setting. Click on Finish to confirm final creation. If there is some mistake, just click on Back until needed page to be fix. (Fig: 2.3.4.H).

Figure 2.3.4.AD

Your Datastore is created and ready to be used. (Fig: 2.3.4.I)

Figure 2.3.4.AE

From this point, Virtual machine creation could be start.

3 Managing ISO files containing OS or Application on Datastore:

3.1 Uploading ISO File on Datastore:

To be able to install OS on Virtual Machine, there is 3 different ways. The First is to link Virtual CD to the Vsphere Client Cdrom Device, the Second to link the Virtual CD to the ESXi Server Cdrom Device and the last 1 and preferred 1 is to use iso file from the Datastore.

To upload or manage file on Datastore, there is 2 way to access it with the Vsphere client. Or via Configuration TAB and Storage Link, right click on the desired Datastore and Select “Browse Datastore” (Fig. 2.3.4.AA) or via Summary Tab, right click on the desired datastore and select “Browse Datastore” (Fig. 2.3.4.BB)

Figure 2.3.4.AFA

Figure 2.3.4.AGB

The datastore windows will appear (Fig 2.3.4.CC). From this windows, you could create, delete move Directory and upload, download, delete and move file inside of the Datastore or to another Datastore.

Figure 2.3.4.AHC

To create a directory, click on the yellow with a icon, to upload a file or a

directory, click on the icon, to download a file or a directory, click on the

icon, to move a file or a directory, click on the icon, to delete a file or a

directory, click on the icon. To refresh the current directory and folder list click

on the icon.

For the upload download delete file and directory management, we will use a little iso file. The first step consists in doing a clean directory to found easily what we are looking. The directory name will be for the first OS and the second APPLICATION.(from Figure 2.3.4DD to 2.3.4.FF)

Figure 2.3.4.AID

Figure 2.3.4.AJE

Figure 2.3.4.AKF

Now we will upload a file into the directory OS and move it after from OS to APPLICATION.

The first step is to select the desired directory (OS). And then click on the upload button (Fig )

Figure 2.3.4.ALG

The second step consist of selecting file to upload and then click on Open button. The upload will start. (Fig. from 2.3.4.HH to 2.3.4.JJ)

Figure 2.3.4.AMH

Figure 2.3.4.ANI

Figure 2.3.4.AOJ

As the ISO file is an application, we will move it from OS to APPLICATION Directory. Select the file and then click on yes button to confirm as it’s not a VM and the file is not link to a VM.

Figure 2.3.4.APK

Figure 2.3.4.AQL

Select the Datastore where the file has to be move and the correct directory inside of the selected Datastore and click on move button to finish (Fig. 2.3.4.MM to 2.3.4.NN).

Figure 2.3.4.ARM

Figure 2.3.4.ASN

The file was move from a directory to another inside of the same Datastore. To move a file or directory from a Datastore to another Datastore, follow same process but select the Datastore where you want to put the file or directory that has to be moved.

3.2 Downloading ISO file from the Datastore:

From the Datastore windows, go in the correct Directory and select the file or directory that you want to download. Then click on the download button.
