• Rapid provisioning and cloning
• Faster upgrades and patching
• Manage many as one

Memory需求，Each x86 64-bit server must have the following minimum memory:
Audit Vault Server: 8 GBFoot 1
Database Firewall: 8 GB

Disk需求，Each x86 64-bit server must have a single hard drive with a minimum of the following disk space:
Audit Vault Server: 220 GB (Recommended is 300 GB)
Database Firewall: 220 GB

Network需求，Oracle recommends the following number of network interface cards (NICs) for each x86 64-bit server on which you install the following components:
1 NIC for the Audit Vault Server
At least 1 NIC for a Database Firewall operating as a proxy
At least 2 NICs for a Database Firewall in DAM Mode (monitoring only)
At least 3 NICs for a Database Firewall in DPE Mode (monitoring and blocking. If you install the Database Firewall with fewer than 3 NICs, then you must add more NICs to make the Database Firewall DPE mode possible.
