vCloud Director Install - Appliance

So here how we will install the vCloud Director (vCD). These are the appliance guidelines,

1. Login to the vCenter, deploy the vCD ovf file using the "Deploy OVF Template" wizard. This is a very straight forward process so I have not detailed all the steps here.

Register the vCenter server in the vShield Manager

Once you are all set with the vShield Manager,

1. Login to the vShield Manager using the web address.

2. Click on "Edit" button under the Lookup service and enter the details.

3. Enter all the details along with SSO credentials.

What is VXLAN?

VXLAN stands for Virtual Extensible LAN for a start.

You will come across this term 'VXLAN' very often when you go along vCloud environment. It is a very large topic and discussion on this can go on for many hours on this.

Install vCNA also known as vShield Manager 5.x

1. First of all download vCNA OVA from VMware.com download page. They should look something like below.

What is SIOC?

Storage I/O Control (SIOC) provides storage I/O performance isolation for virtual machines, thus enabling VMware® vSphere™ (“vSphere”) administrators to comfortably run important workloads in a highly consolidated virtualized storage environment. It protects all virtual machines from undue negative performance impact due to misbehaving I/O-heavy virtual machines, often known as the “noisy neighbour” problem. Furthermore, the service level of critical virtual machines can be protected by SIOC by giving them preferential I/O resource allocation during periods of congestion. SIOC achieves these benefits by extending the constructs of shares and limits, used extensively for CPU and memory, to manage the allocation of storage I/O resources. SIOC improves upon the previous host-level I/O scheduler by detecting and responding to congestion occurring at the array, and enforcing share-based allocation of I/O resources across all virtual machines and hosts accessing a datastore.
