Infrastructure Settings
In the second plane of the installer, make choices relating to the VMs and the virtual infrastructure.
- Virtual machine size—Vertica engineers have designated the three different VM types for deployment that are available on the Azure Marketplace. When you highlight this field, Azure displays those types and their specific characteristics.
-
Number of cluster nodes—This drop-down field allows you to choose the number of nodes for Azure to deploy for the cluster. The Marketplace solution allows you to create between 1 and 15 nodes.
Important: To maintain K-safety for your database, select at least three nodes.
- Total RAW storage per node—Each VM comes configured with a premium data disk for Vertica to use. The choices in this drop-down are 768GB, 3TB, or 6TB.
- Storage account name prefix—All disks associated with the cluster are contained in a group of four premium storage accounts. Storage accounts must each have a unique name. When Azure creates the storage accounts, the Marketplace appends a number to the end of each name.
- Storage account type—Because Vertica is a high-end enterprise solution that requires fast, low-latency storage, Premium-LRS storage is the only available choice for this field.
- Virtual network—The Azure Marketplace solution for Vertica allows you to create a new virtual network, or select an existing virtual network, in which to place the Vertica cluster. This control on the deployment provides a point-and-click navigation to do just that.
- Subnets—Based on the selection of the virtual network, the Subnets entry allows you to select or create the subnet you want use in the virtual network.
- Public IP address—Each VM is configured with a publicly accessible IP address. This field allows you to specify the resource name for those IP addresses, and whether they are static or dynamic. When created, Azure appends a number from 1 to 15 to each resource name. This number designates which VM that the resource is associated with.
- Domain name label—Because each VM has a public IP address, each node also needs a DNS name. Enter a prefix for the name, such as
vertnode
. Azure appends a number from 1 to 15 to the DNS name. That number designates which VM it is associated with. Azure adds the remaining part of the fully qualified domain name based on the location where you created the cluster.
