Day-4 Deploy SDDC
And today we are going to deploy our first SDDC :)
For seamless deployment of the SDDC its important that we should do some homework first
Prerequisites :
# Ensure you have an AWS account before you create an SDDC
# You will have to create subnets with atleast 64 Ips (/26)
# The subnet should be in the same AWS Region where you are planning to deploy the SDDC
# Its important that you create Subnets in each availability zone in your VPC
# As mentioned earlier 192.168.1.0/24 should not be overlapped by the IP range of these subnets.
# 192.168.1.0 is reserved for Default Compute gateway logical network
Log in to the VMC Console at https://vmc.vmware.com.
Click Create SDDC.
3. From Connect to an AWS account Dropdown either select an existing account (This should not be already in use by any other SDDC .. SDDCs have one to one mapping with AWS account and vpc.)
If the account is not mentioned in the list you can choose connect to a new AWS account.
VMware has defined a CloudFormation template to connect an AWS account. This template creates the IAM roles necessary to allow communication between your SDDC and your AWS account.
Once the connection is successfully established you get :
4. Configure SDDC properties.
Enter a name for your SDDC.
Select the number of hosts in the SDDC.
Select the AWS region in which to deploy the SDDC (Same region where you created your subnets)
5 Select a VPC and a subnet in your AWS account to connect to.
Click Next
6. Enter an IP address range for the management network as a CIDR block or leave the text box blank
to use the default, which is 10.0.0.0/16.
You can't change the values specified for the management network after the SDDC has been created.
Consider the following when you specify this address range:
The IP address range 192.168.1.0/24 is reserved for the default compute gateway logical network of the SDDC you are deploying. If you specify a management network address range that overlaps with 192.168.1.0/24, no default compute gateway logical network is created during deployment and you will have to create one manually after the SDDC is deployed.
Only CIDR blocks of size /16, /20, or /23 are supported.
Choose a range of IP addresses that does not overlap with the AWS subnet you are connecting to. If you plan to connect your SDDC to an on-premises data center, the IP addresses you choose must be different from the ones in your on-premises data center, to avoid IP address conflicts.
The maximum number of hosts your SDDC can contain depends on the size of the CIDR block you specify. If the CIDR block is in the form XXX.XXX.XXX.XXX/YY, then the maximum number of hosts the SDDC can contain is (2 ^(27 - YY)) - 3. The table shows the number of hosts based on the value of YY.
Click on Create SDDC, This will initiate the SDDC creation and will configure all the Management components for you. this process may take 2-6 Hours to complete.
and once this is completed you will see a new sddc in your vmc org page.
