About this Guide This guide describes how to install Hybrid Cloud Manager Version 1.0 Update 1. It also guides you through vSphere Web Client workflows to deploy and configure Software-Defined WAN components (including WAN Optimization), to migrate workloads to the cloud and back, and extend on-premises VLAN and VXLAN networks from your datacenter to vCloud Air. Intended Audience This document is intended for datacenter administrators familiar with vSphere virtualization.
• • Dedicated scale out L2 Concentrators can be deployed and used in conjunction with Direct Connect to increase throughput • Multiple Direct Connects and fail-back to Internet are supported • Extended Networks are linked to vCloud Air Advanced Network Services Edge appliances in Org Gateway position and can be announced back to the Enterprise once all virtual machines are migrated and the network is unstretched • Egress path optimization (optional) to allow shortcut routing between virtual machines
Figure 1: Installation Components Installation Overview This is a brief summary of the Hybrid Cloud Manager installation tasks. 1. Identify the architecture you want to use (see “Use Cases”). 2. Log into My VMware and download the Hybrid Cloud Manager OVA file from the product download page: https://my.vmware.com/en/group/vmware/details?downloadGroup=HCM100&productId=343 3. From vSphere, install the Hybrid Cloud Manager virtual appliance in the on-premises vCenter that will connect to vCloud Air.
Table 1: Virtual Machine Installation Resource Requirements VM vCPUs RAM Installation Hybrid Cloud Manager 4 12 GB Required. Hybrid Cloud Gateway 2 2 GB Required. Layer 2 Concentrator (L2C) 6 8GB Optional for migration, required for stretched Layer 2, or migration over stretched Layer 2. WAN Optimizer 8 14 GB Optional.
patterns to reduce bandwidth usage and insures best usage of available network capacity to expedite data transfer to and from vCloud Air.
Migration Only In Table 2, cases ❶ and ❷ are for migrating without an L2 extension. Other than the Hybrid Cloud Manager, only the Hybrid Cloud Gateway appliance is required. The basic difference between cases ❶ and ❷ is that higher speed is possible with the Hybrid Networking Premium option. WAN optimization, if installed, can improve security and speed in the situations described in “WAN Optimizer” on page 8.
Separate Migration and Data Paths The Cloud Gateway and the L2C service appliances use different outbound IP addresses. In this configuration, the L2C appliance data path does not benefit from WAN Optimization or intelligent routing, but workloads travelling through the Cloud Gateway do. This might not be an issue if the host-to-host traffic on the data path is already encrypted or compressed.

Verify the Minimum Installation Environment Before the installation, ensure that you have the following resources in your on-premises vCenter and your vCloud Air vDC. On Premises • An on-premises Virtual Center created with vSphere 5.5 Update 1 or above. • Administrator access to the source Virtual Center and any resources you want to connect to the cloud.
• When installed, the on-premises L2 Concentrator service appliance must have access to a vNIC port and any vLANs you want to stretch. • If you choose to stretch a network over the public internet or your own VPN (on an alternate path, not the Hybrid Cloud Gateway) then the L2C VM in your vCloud Air vDC also requires an IP address. If your architecture specifies multiple L2Cs, each must have an IP address. You must know the remote IP address before you configure the L2C.

Stretching an L2 Network to vCloud Air This procedure extends a Layer 2 network from the on-premises data center to vCloud Air. Note: This process uses the Extend Network wizard.
3. Right-click the port group, select Hybridity Actions and click Extend Network. The “Extend network to vCloud Air” wizard opens. 4. On the “Select source port groups” page, confirm the port group information and enter the IP address and subnet mask for the Default Gateway used by this network. Click Next. 5. On the “Select destination gateway” page: a. Choose the vCloud Air Organization. b. Choose the vCloud Air Virtual Datacenter.
c. Leave Enable Egress Optimization unchecked if you want a cloud VM to use the on-premises gateway to access the internet. Many organizations prefer this for security reasons. If you check Enable Egress Optimization, a VM in the cloud can use a cloud gateway (that you specify) to access the internet, rather than the on-premises gateway. d. Select the remote destination gateway from the list of gateways. Click Next. 6. On the Ready to complete page, review all values provided. Click Finish.
7. To track the progress of the network extension, go to the Recent Tasks window, click the All tab, and ensure you are viewing All Users’ Tasks. Click on More Tasks to open the Task Console. The network extension is done when the Extend Network task status is Completed. Migrating a Virtual Machine to vCloud Air To migrate a virtual machine you must have a secure connection maintained by the Hybrid Cloud Gateway.
5. Following the switchover, the source virtual is powered-off, and the migrated replica is powered on. 6. Hybrid Cloud Manager renames the powered-off replica to avoid a naming conflict with the live VM. A binary timestamp is appended to the replica name. The migration is complete, and conceptually, this is where replication stops. • Powered off replicas are stored in your on-premises vCenter in folders named “VMs migrated from the cloud,” and “VMs migrated to the cloud.
1. On the Hosts and Clusters page, right-click the VM you want to migrate, and from the context menu, select Hybridity Actions, and choose Migrate to vCloud Air. 2. In the Migrate Wizard on the “Select migration type” page, select an option that suits your purpose. • Quick Switchover: Switch over as soon as the sync is ready. • Scheduled Switchover: Switch over in a pre-determined maintenance window. To duplicate the sample procedure, select the Replication based Migration with Quick Switchover option.
4. On the “Select destination page,” select the vCD Organization and vCloud Air virtual datacenter. Click Next. 5. On the “Select destination” network page, select the NSX Edge associated to the vCloud Air datacenter. Click Next. • The Retain MAC box is checked by default if the VM is being migrated to a network that has been stretched. The source (on-premises vCenter or vCloud Air vDC) does not matter.
• • Linux NIC Order: In Linux, if you change the MAC address of a VM, the Ethernet device number of the NIC may change after a reboot. This effectively changes the NIC order as it is presented within the operating system, breaking scripts or software that depends on NIC order. If you uncheck Retain MAC a new MAC address is obtained when the VM migration is complete. 6. On the Select storage tier, confirm the selection and click Next. 7.
b. CLI: Log in to the ESXi host running the virtual machine using SSH. Run this command to obtain the virtual machine ID: # vim-cmd vmsvc/getallvms | grep -i vmname Vmid Name File 6 WordPress_App [storage]WordPress_App/WordPress_App.vmx Guest OS otherLinuxGuest Version vmx-10 Run these commands to monitor replication state using the Vmid obtained in the previous step: # vim-cmd hbrsvc/vmreplica.getState vmid # vim-cmd hbrsvc/vmreplica.queryReplicationState vmid c.
