vSAN 6.7U1 Captures

vSAN 6.7U1 finally lets you create a vSAN cluster with the new vSphere Client

There is a new Cluster quickstart...

It allows you to add hosts and create a dvs very easily...

Services like dedup and compression, encryption and iscsi can be easily configured now.

 Same applies to disk groups...

The Health UI is very different as you can see...

Takes a while to get used to...

vSAN Cluster via PowerCli

Building a vSAN cluster with PowerCLI

Step 1: Connect to the vCenter Server
connect-viserver sa-vcsa-01.vclass.local

Step 2: Create a datacenter
new-datacenter -Location (get-folder -norecursion) -name “javier datacenter”

Step 3: Add your servers to your datacenter
add vmhost sa-esxi-02.vclass.local -location “javier datacenter” -user root -password VMware1!
add vmhost sa-esxi-03.vclass.local -location “javier datacenter” -user root -password VMware1!

Step 4: Create a distributed virtual switch for vSAN
new-vdswitch -name vsanswitch -location “javier datacenter”
get-vdswitch -name vsanswitch | new vdportgroup -name vsanpg
get-vdswitch -name vsanswitch | add vdswitchvmhost -vmhost sa-esxi-01.vclass.local, sa-esxi-02.vclass.local, sa-esxi-03.vclass.local
$nic1=get-vmhost sa-esxi-01.vclass.local | get  vmhostnetworkadapter -physical -name vmnic3
$nic2=get-vmhost sa-esxi-02.vclass.local | get  vmhostnetworkadapter -physical -name vmnic3
$nic3=get-vmhost sa-esxi-03.vclass.local | get  vmhostnetworkadapter -physical -name vmnic3
get-vdswitch vsanswitch | add-vdswitchphysicalnetworkadapter -vmhostphysicalnic $nic1
get-vdswitch vsanswitch | add-vdswitchphysicalnetworkadapter -vmhostphysicalnic $nic2
get-vdswitch vsanswitch | add-vdswitchphysicalnetworkadapter -vmhostphysicalnic $nic3
new-vmhostnetworkadapter -vmhost sa-esxi-01.vclass.local -portgroup vsanpg -virtualswitch vsanswitch -IP -subnetmask -vsantrafficenabled $true
new-vmhostnetworkadapter -vmhost sa-esxi-02.vclass.local -portgroup vsanpg -virtualswitch vsanswitch -IP -subnetmask -vsantrafficenabled $true
new-vmhostnetworkadapter -vmhost sa-esxi-03.vclass.local -portgroup vsanpg -virtualswitch vsanswitch -IP -subnetmask -vsantrafficenabled $true

Step 5: Create a cluster enabled for vSAN and DRS
new-cluster -name “javier cluster” -vsanenabled -drsenabled -location “javier datacenter”

Step 6: Add the servers to the cluster and then enable HA
get-vmhost sa-esxi-01.vclass.local | move-vmhost -Destination “Javier cluster”
get-vmhost sa-esxi-02.vclass.local | move-vmhost -Destination “Javier cluster”
get-vmhost sa-esxi-03.vclass.local | move-vmhost -Destination “Javier cluster”
set-cluster -cluster “Javier cluster” -HAEnabled:$true

Step 7: Create the diskgroups for the hosts
new-vsandiskgroup -vmhost sa-esxi-01.vclass.local -ssdcanonicalname mpx.vmhba0:C0:T1:L0                     -datadiskcanonicalname mpx.vmhba0:C0:T2:L0, mpx.vmhba0:C0:T3:L0
new-vsandiskgroup -vmhost sa-esxi-02.vclass.local -ssdcanonicalname mpx.vmhba1:C0:T1:L0                     -datadiskcanonicalname mpx.vmhba1:C0:T2:L0, mpx.vmhba1:C0:T3:L0
new-vsandiskgroup -vmhost sa-esxi-03.vclass.local -ssdcanonicalname mpx.vmhba1:C0:T1:L0                     -datadiskcanonicalname mpx.vmhba1:C0:T2:L0, mpx.vmhba1:C0:T3:L0

Step 8: Verify disk and disk group related information

Step 9: Create a fault domain with two servers
new-vsanfaultdomain -name domain1 -vmhost sa-esxi-01.vclass.local, sa-esxi-02.vclass.local

Step 10: Add a host to your fault domain
set-vsanfauldomain domain1 -addvmhost sa-esxi-03.vclass.local

Step 11: Remove the third host from the fault domain
set-vsanfaultdomain domain1 -removehost sa-esxi-03.vclass.local

Step 12: Remove the fault domain
remove-vsanfaultdomain domain1

Step 13: Create two vsan virtual machine storage policies
get-command “*spbm*”
get-spbmcapability VSAN*
new-spbmstoragepolicy -name PFTT=2 -anyrulesets (new-spbmruleset (new-spbmrule -Capability (get-spbmcapability -Name “VSAN.hostFailuresToTolerate”) -Value 2 ) )
new-spbmstoragepolicy -name RAID10 -anyrulesets (new-spbmruleset (new-spbmrule -Capability (get-spbmcapability -Name “VSAN.hostFailuresToTolerate”) -Value 1 ), (new-spbmcapability -name “VSAN.stripeWidth” ) -Value 2) )

Step 14: Export one of the policies
export-spbmstoragepolicy -storagepolicy RAID10 -filepath C:\

Step 15: Remove a policy that is not in use
remove-spbmstoragepolicy -storagepolicy RAID10

vROPS 6.6 and vSAN

What's New?

Product Enhancements

vRealize Operations Manager 6.6 focuses on enhancing product usability, accelerating time to value and improving troubleshooting capabilities.
  • Simplified usability and faster time to value capabilities:
    • New HTML5 user interface provides an easier and consistent experience.
    • The Getting Started dashboard allows for quick navigation.
    • Persona based dashboards provides for answers in one place. Dashboards are separated into categories such as Operations, Capacity and Utilization, Performance Troubleshooting, Workload Balance, and Configuration and Compliance.
    • Out of the box integration with vSAN and vRealize Automation provides quick time to value.
    Watch videos related to the new dashboards that are introduced with vRealize Operations Manager 6.6 here.
  • Added Native vSAN management capabilities:
    • Allows for centralized management across stretched clusters.
    • Ability for complete vSAN management, which includes administering performance, capacity, logs, and configuration and health.
Here are some captures:

1. Log into the admin page and ensure everything is functional.

2. Look for any updates available...

3. Once you are done, log out from the admin page and log in again. Notice the url...

4. As you will notice, the UI is now HTML5 and very different than it used to be. Notice the vSAN related captures.

Note: I guess next time I will actually have a vSAN cluster in place for testing. LOL
