VMware Virtual SAN, or vSAN, is a distributive layer of Native-based software that runs as part of the ESXi Hypervisor. vSAN collects a local capacity or equipment direct connection of a Host Cluster and creates a pool pool and shared host across the vSAN cluster. With the vSphere 6.7 Update v1.6 package, version 6.7 is available. We will also launch vSAN with this version and launch our lab under the following conditions:
- We need at least 3 ESXi hosts that we have added 5 hard drives to each host in this scenario. (4 hard drives with a capacity of 40GB and a hard drive with a capacity of 20GB)
- Each host has 2 network cards, 8 GB of memory and 4 vCPUs
- A VCSA 6.7 U1 server
- According to VMware, the scenario will be based on Distributed vSwitch
- A VMKernel Port for passing Virtual SAN traffic
Operating modes vSAN:
There are two modes for vSAN operation: Hybrid or All-Flash. In the All-Flash mode, SSD drives can also be considered as the main storage space for data storage, as well as being used as a Write Buffer. In Hybrid mode, you can use magnetic disks alongside SSDs, in which case SSD drives are used as Read Cache and Write Buffer, and no information is stored on them.
Host Transfer from Standard vSwitch to Distributed vSwitch:
In the initial sections of this tutorial, the launch of the lab and the platform for launching vSAN will be taught, and ultimately we will serve with the vSAN launch. Enter the VisServer vSphere Client (HTML5) environment and add the host to the VCSA. Then create a Distributed vSwitch with two Upink called Management and vSAN (presumably familiar with these topics and not trained).
Click on Distributed vSwitch and select Add and Manage Hosts.
In the popup window, select the Add Hosts option and click Next.
Then, click on the new hosts and select the hosts as in the image below.
Next, after clicking on vmnic0, select Uplink Assign.
After selecting the desired Uplink (as mentioned above, Distributed vSwitch has two Uplinks, we named them Management and vSAN), which we consider for this stage of Management; Apply this uplink assignment to the rest of the hosts to apply to all hosts.
Next, you need to assign your VMkernel to a Port Group.
Next, click on Next (because we do not have a VM yet, nothing will be displayed).
Click Finish in the end to finish the task of transferring hosts from Standard vSwitch to Distributed vSwitch.
