HCX - Extend Network, Migrate VMs
Welcome to this demonstration on Installing HCX in VMware Cloud
Foundation.
The purpose of this demonstration is to show how easy it is to
migrate existing VMs from an existing legacy site running VMware vSphere 5.5
into a new modern hybrid cloud infrastructure with VMware Cloud Foundation
using VMware HCX.
In this demo, we will show how to extend a layer 2 network using
HCX.
Then we will live migrate the VMs on that network to VMware Cloud
Foundation.
We begin
at the source legacy VMware vSphere 5.5 Web client. Where we are currently on
the HCX dashboard. We can see Site pairing is completed, and we are now ready
to extend a layer 2 network to VMware Cloud Foundation.
This demo
has automatically keyed in the Gateway for this VLAN.
We can
see that the network Extension is complete. In the background HCX has automated
the creation of a new overlay network (Geneve/VXLAN) inside the VMware Cloud
Foundation environment. We can now use this extended network to move VMs from
the VMware vSphere 5.5 environment to VMware Cloud Foundation. During this
migration the VMs will remain live and online.
The HCX
Workload Mobility Screen has appeared. This user interface is part of the HCX
Enterprise License feature set. The mobility group interface allows us to
create a mobility Group of VMs. For this demo we will group together three VMs
that are part of an entire application set. To begin, enter a name for this mobility
group.
Next we
will search for the remaining parts of this application.
We now
have all three VMs in the HCX Mobility Group.
Next we
need to select the destination parameters for migration.
From the
Migration Profile list, we have several choices for migration available.
vMotion - Moves
one VM at a time using the vMotion protocol.
Bulk
Migration - Is a warm migration of multiple VMs at a time. Bulk, first
syncs the virtual disks using built in vSphere Replication protocols. Once the
disks are in sync at the destination site, and a maintenance window has been
reached, the VMs are powered off on the source, then powered on at the
destination site. A very short window of downtime is required for bulk
migration.
The last
two migration methods are part of the HCX Enterprise licensing feature set.
OS Assisted
Migration - Allows HCX to Migrate VMs from Non-VMware Hypervisors, like
KVM.
Replication-assisted
vMotion (RAV)- Is a combination of VMotion and Bulk Migration. This method
allows for bulk live migration of up to 100 VMs at once. RAV begins by synchronizing
the disks from source to destination. Once the disks are in sync, the state of
the VMs CPU and RAM are then copied to the destination using vMotion. For this
demo we will use RAV.
If you
need to follow a specific maintenance window for migrations, you can set the date
and time for that here.
The
migration begins with synchronizing the base disks, then proceeds to the
switchover (vMotion) phase. After a few minutes all three VMs have been
migrated to the new VMware Cloud Foundation Environment.
We can
see App-1 VM is up and migrated into VMware Cloud Foundation without downtime.
Web-1 and Database1 have also been migrated successfully.
This
concludes our demo on Installing, Configuring and Migrating VMs to VMware Cloud
Foundation with HCX
