VCP6-DCV blueprint section 3:Configure and Administer Advanced vSphere 6.x Storage -Objective 3.2 – Part 1

In this post we will continue covering the storage objective from the blueprint. Again I will NOT follow the order of blueprint objective but i will cover all of them.

The following are the blueprint objective:

  • Explain VSAN and VVOL architectural components
  • Determine the role of storage providers in VSAN
  • Determine the role of storage providers in VVOLs
  • Explain VSAN failure domains functionality
  • Configure/Manage VMware Virtual SAN
  • Create/Modify VMware Virtual Volumes (VVOLs)
  • Configure Storage Policies
  • Enable/Disable Virtual SAN Fault Domains
  • Create Virtual Volumes given the workload and availability requirements
  • Collect VSAN Observer output
  • Create storage policies appropriate for given workloads and availability requirements
  • Configure VVOLs Protocol Endpoints

The following objective I will not be able to demonstrate since i am using VMware Workstation and not real HW but i will try to point to the configuration location

  • Create/Modify VMware Virtual Volumes (VVOLs)
  • Configure VVOLs Protocol Endpoints

Also since there is a lot to cover i will use multiple post and i will split vSAN and VVOL subjects

For vSAN we will need to use the following documents from VMware:

So let start with VSAN


Explain VSAN components

 

 

vSAN1

Source: VMwareVirtual SAN Whats New document

vSan architecture include the followings:

  • Minimum of three hosts in a cluster
  • SSD and HDD minimum one of each
  • Separate networking minimum 1G connection
  • VMkernel Port.

Configure/Manage VMware Virtual SAN

In this section I will configure vSAN in my current lab

The plan:

  • Networking – i will create new dVS with new VMkernels for vSAN traffic (this is not a must , you can use the existing vDS and allow vSAN traffic on it  but i will like to separate the vSAN traffic for more practice
  • Adding two more disks for each ESXi hosts (we will do it via VMware workstation)
  • Re-scanning the ESXi hosts for the new storage
  • Assign SSD to each ESXi host
  • Enable vSAN
  • Claim and assign diskgroups in each ESXi host
  • Verify vSAN datastore
  • Moving VM’s to vSAN

 

So lets get started:

New vDS switch configuration, i will not create all the screenshots for new vDS you can look at my previous networking posts. here is the screenshots of the vDS setup.

vSAN_config1

Make surer to enable “Virtual SAN traffic” in the new VMkernel

vSAN_config2

Adding 2 virtual disks to each ESXi host via VMware Workstation

vSAN_config3

Re-scan each ESXi host for the newly add drives

vSAN_config4vSAN_config5

Assign one drive as a Flash drive on each ESXi hosts

vSAN_config6

Turning ON vSAN on the clsuter: Click on Cluster >> Manage>> Setting>>under vSAN General click on the Edit button >> Turn ON Virtual SAN >> change the setting to manual and click Ok.

vSAN_config7

After this is done you verify that you can see all 3 hosts ad network status is normal.

vSAN_config8

Under Disk Management we can now claims disks from each ESXi host to create diskgroups.

vSAN_config9

On each ESXi host choose One SSD and one HDD from the previous configuration

vSAN_config10

Results:

vSAN_config11

Verify that you have a new vSAN datastore

vSAN_config12

Now lets migrate VM;s (i have only one) to the new vSAN datastore. choose storage only

vSAN_config13

Choose vSAN datastore.

vSAN_config14

Thanks for reading

Mordi.
