Five-Part Recertification Blog Series Launching to Share Insights, Opinions
As a reminder, there are three options when you recertify:
1. Update your existing VCP certification (eg: if you are a VCP 3, take the VCP5-Data Center Virtualization (VCP5-DCV) exam.
2. Earn a new VCP certification in a different solution track – such as Cloud, End-User Computing or Certified Professional Portals
3. Go to the next level, by earning a VMware Certified Advanced Professional (VCAP) certification. For example, if you are a VCP5-DCV you could earn VCAP5-DCA certification.

Org VDC Edge Services
Edge Gateways
An Edge Gateway provides a routed connection between an organization vDC network and an external network. It can provide any of the following services, defined in the GatewayFeatures element of the Edge Gateway's Configuration.
Specifies firewall rules that, when matched, block or allow incoming or outgoing network traffic.

| Number of load balancer virtual servers | 3,000 |
| Number of members in load balancer pools | 30,000 |
The following table provides information on the tested soft limits per vCloud Networking and Security Edge:
| Limit | vCloud Networking and Security Edge |
| Number of interfaces | 10 |
| Number of firewall rules | 2,000 |
| Number of NAT rules | 2,000 |
| Number of DHCP static bindings | 25 |
| Number of DHCP pools | 10 |
| Number of static routes | 100 |
| Number of load balancer pools | 3 (Hard limit: 64) |
| Number of load balancer virtual servers | 3 (Hard limit: 64) |
| Number of members per load balancer pool | 10 (Hard limit: 32) |
| Concurrent IPSec VPN Tunnels | 64 |
| Concurrent SSL VPN Tunnels | 25 (Compact), 100 (Large) |
Firewall and VPN Performance Comparison
| Edge (Compact) | Edge (Large) | |
| Firewall Performance (Gbps) | 3 | 9.7 |
| Concurrent Sessions | 64,000 | 1,000,000 |
| New sessions/second | 8,000 | 50,000 |
| IPSec VPN throughput (Gbps) - H/W acceleration via AESNI | 0.9 | 2 |
Load Balancer Performance Comparison
| Edge (Large) | Edge (X-Large) | |
| Load balancer throughput – L7 Proxy Mode (Gbps) | 2.2 | 3 |
| Load balancer connections / sec – L7 Proxy Mode | 46,000 | 50,000 |
| Load balancer concurrent connections – L7 Proxy Mode | 8,000 | 60,000 |
| Load balancer throughput – L4 Mode (Gbps) | 6 | 6 |
| Load balancer connections / sec – L4 Mode | 50,000 | 50,000 |
| Load balancer concurrent connections – L4 Mode | 600,000 | 1,000,000 |
Notes:
- VMware recommends you to use Edge (Large) or Edge (X-Large) for load balancing
- Edge (X-Large) is not available in the vCloud Director deployment
Test Server Configuration
- Dell PowerEdge T610 with ESXi 5.1
- CPU – 8 CPUs x 2.393 GHz Intel(R) Xeon(R) CPU E5620
- Memory – 24 GB
- Network – 2x Intel 82599EB 10-gigabit SFI/SFP+
Test Methodology
- IXIA IX Chariot applications used for throughput, connections per second, and concurrent connections tests.
- Throughput measured with 1500 byte TCP frame size.
- Throughput measured with accept any to any firewall rule and no additional NAT rules.
- Load balancer performance numbers are for HTTP traffic.
- Feature performance quoted is independent of other features. For example, firewall throughput measured without load balancer or other services enabled.

Differences between Compact, Large and X-Large Edge Gateway appliances?
The vCloud Networking and Security Edge Gateway is available in three different sizes: Compact, Large, and X-Large. As part of the Edge Gateway deployment, we need to select the appliance size in the wizard as shown below.
The three different Edge Gateway appliances consume different resources and offer different performance levels. The resources used by three different Edge Gateway appliances and their performance levels based on VMware internal testing are posted in the vCloud Networking and Security 5.1 Edge configuration limits and throughput KB article.
As indicated in the KB article, Large appliance offers higher throughput compared to Compact appliance in terms of firewall performance, number of concurrent sessions, and IPSec VPN throughput.
| Edge (Compact) | Edge (Large) | |
| vCPU | 1 | 2 |
| Memory | 256 MB | 1 GB |
| Firewall Performance (Gbps) | 3 | 9.7 |
| Concurrent Sessions | 64,000 | 1,000,000 |
| IPSec VPN throughput (Gbps) – H/W acceleration via AESNI | 0.9 | 2 |
Use of Large or X-Large appliance recommended for using Edge Gateway load balancing service. X-Large appliance uses much higher memory and allows higher number of concurrent load balancer connections than Large appliance. The X-large Edge Gateway is not currently supported with vCloud Director 5.1. As the picture above shows, the X-Large deployment model has some limitations, such as a lack of SSL VPN support.
| Edge (Large) | Edge (X-Large) | |
| vCPU | 2 | 2 |
| Memory | 1 GB | 8 GB |
| Load balancer throughput – L7 Proxy Mode (Gbps) | 2.2 | 3 |
| Load balancer connections / sec – L7 Proxy Mode | 46,000 | 50,000 |
| Load balancer concurrent connections – L7 Proxy Mode | 8,000 | 60,000 |
Another cool feature offered with Edge Gateway deployment is we can start with one appliance and move to a different appliance at a later time. For example, we can deploy Edge Gateway Compact appliance and later upgrade to Large or X-Large with a click of a button as shown below.
In summary, choose the Edge Gateway appliance that suits your environment based on the resources consumed and the performance levels offered.
