Database networks carry SQL traffic to and from Data Director databases. Database clients such as
JDBC and libpq send and receive SQL traffic from database servers on these networks. Data Director
supports multiple database networks for better network isolation, for example, to isolate QA SQL traffic
from production SQL traffic. See Chapter 2, “Planning the Network Configuration,” on page 13.

Hardware to run the test application
Data Director licensing supports up to 32 vCPUs.
Data Director provides several database resource templates in different sizes: tiny, small, medium, large,
and giant. Estimate the resources that your Data Director deployment requires based on your installation's
expected database sizes. For example, a database instance that uses the Tiny database resource template has
the following settings.
Table 1‑1. Settings for a Tiny Database Configuration
Resource Setting
vCPUs 1
Memory size 512MB
Recommended database storage allocation 2GB
For a base installation that uses the Tiny database template, use a cluster with the following CPU and
memory resources.
Table 1‑2. Resource Requirements for a Base Installation Using the Tiny Resource Template
Resource Requirements
CPU 4GHz and an additional 400 MHz for each database instance
Memory 8GB of available memory and an additional 512 MB of available memory for each database instance
Express Setup and Advanced Setup
Data Director provides Express and Advanced setup options. Express setup lets you deploy Data Director
for development or experimentation. Advanced setup is suitable for production environments that require
high availability and performance.
Before beginning the Data Director installation, determine whether to use Express setup to create a
simplified Data Director deployment for development, or Advanced setup to create a production
deployment.
Express setup is supported for a single VLAN network used with static IP addresses instead DHCP. If you
do not adhere to these requirements, the Express setup option is disabled, and you must perform the
Advanced setup.
vSphere Settings for Data Director
Before you can install Data Director, set up the vSphere Cluster to deploy Data Director to, and enable the
cluster for vSphere High Availability (HA), and vSphere Dynamic Resource Scheduler (DRS). Data Director
also requires that you have Network Time Protocol (NTP) enabled in your environment.
Create and Configure the Data Director Cluster
Before you can install the Data Director vApp, you have to create and configure the Data Director cluster.
A cluster is a group of hosts. When a host is added to a cluster, the host's resources become part of the
cluster's resources. Clusters enable the vSphere High Availability (HA) and vSphere Distributed Resource
Scheduler (DRS) solutions. Cluster settings must be compatible with Data Director.
