5 allocating iSCSI storage space for VMware ESXi

Return to the Windows Server R2 host, open the Iscsitarget program, create an iSCSI target, and assign two disks to it. The allocation target can be either the IP address of the VMware ESXi or the MAC address, as an example of the MAC address of the ESXi network card in this example.

(1) in iSCSI target, right-click to select "Create iSCSI Target", as shown in 5-1.

Figure 5-10 Virtual Disk File

(11) Set the first virtual disk size to 1024000 (that is, 1TB), as shown in 5-11. Note that the disk size will be allocated immediately, if you do not have such a large disk space, please set a small disk space, after the article to do Windows 2003 fault tolerance, the minimum is only 2GB. So you can assign a dozens of GB disk.

6 Creating a datacenter, clustering, and adding hosts to a cluster

Next, use vsphere Web client to sign in to Vcenter Server, create a datacenter, cluster, and add a virtualization host to the cluster, the main steps are as follows.

(1) Log in to the vsphere Web Client and select "Hosts and Clusters", as shown in 6-1.

Figure 6-5 Creating a new cluster

(6) in "EVC" in advance, select "Intel Haswell Generation", which supports Intel Core i7 4790K cpu,6-6 shown. When you actually use, please choose according to your host. If you don't know how to choose, you can choose the highest one here (the current item is the highest item).

Figure 6-6 eVC Options

(7) Return to the Vsphere Web Client interface and add the host. If your EVC option is correct in the previous step, select the cluster on the left and add host on the right to add the host that you added later to the cluster directly. If you don't know the EVC option for your ESXi host, you can select the data center on the left and click Add Host on the right to add the ESXi host to the datacenter. When a host is added to the datacenter, the EVC option for ESXi is visible in the summary for the host, so that it can be moved to the cluster, depending on the EVC option detected by the system, and then back to the Clustered Configuration dialog box, after changing the EVC option. As shown in 6-7, this is the Select page for the Add host.

Figure 6-14 Adding complete

Additional ESXi hosts are then added to the data center, which are not described.

Return to the vsphere Web Client, select a host on the left, and in summary → configuration on the right, you can see the EVC mode supported by the current host, as shown in 6-15. In the EVC mode supported by the ESXi host, the first row of the list is the mode supported by the previous lower-end CPU, and the last line is the newer CPU-supported mode (i.e., the higher the CPU model is required later). Make a note of the last line pattern. If there are different CPUs in the current datacenter, if you want to place these hosts in a cluster, you need to benchmark with the lowest CPU support.

Figure 6-15 Note the EVC mode

If you are setting up a cluster, EVC chooses the wrong mode, at which point you can modify the cluster configuration, select the appropriate EVC mode, and then move the added host to the cluster, as shown in 6-16.
