Network

Port Speed Options

Each server comes standard with 100Mbps Public and Private network ports. For servers with high bandwidth or Private network utilization we offer speeds up to 10Gbps. For redundant network connectivity we offer dual uplink configurations that feature redundancy on both the public and private network ports (four uplinks total per server) on compatible servers, eliminating single points of failure.

Bandwidth

Multiple Public Network bandwidth options, including both metered or unmetered, are available for each server. This allows for custom configurations to suit individual server requirements.

IPv4 Addresses

Each SoftLayer server comes with 1 primary IPv4 address standard. Additional IPv4 addresses are available in quantities of 1, 2, 4, 8, 16, or 32. Note, a limited number of IPv4 addresses are available; justification of IPv4 address request may be required. Global IPv4 IP addresses are available as single /32 addresses with a limit of 5 per customer. Prices for IPv4 addresses may vary for Singapore based servers.

IPv6 Addresses

Each SoftLayer server optionally comes with 1 primary IPv6 address. Additional IPv6 addresses are available in /64 blocks. Global IPv6 IP addresses are available as /64 blocks with a limit of 5 per customer.

Additional Information

SoftLayer offers three main types of IP addresses:

• Static IP Addresses: Route directly to a specific IP or resource on the SoftLayer network.
• Portable IP Blocks: IP blocks that can be routed to multiple resources within a single VLAN—physical or virtual.
• Global IP Addresses: IPs that can be pointed at any CloudLayer Computing Instance or dedicated server in any SoftLayer data center around the world, allowing workloads to transition between resources without having the IP lifecycle tied to a specific server or VLAN.

Local Load Balancing

SoftLayer Local Load Balancing utilizes industry-standard techniques including round-robin, lowest latency, least connections, shortest response and IP persistence to balance traffic among 2 or more servers. It can be activated and configured in real-time, with servers added to or removed from the balancing pool on-demand with little or no downtime.

In addition, Local Load Balancing with Secure Socket Layer (SSL) offloading streamlines performance, improves scalability and manageability and reduces the number of SSL certificates you require by processing and securely decrypting incoming traffic at the load balancer instead of at each individual server.

Global Load Balancing

Softlayer Global Load Balancing offers geography based, round-robin weighted round-robin, and failover load balancing across and between all SoftLayer facilities. By using an Anycast DNS system, the global load balancer is capable of providing highly redundant DNS resolution to clients as well as directing clients to the optimal data center site relative to location. It can be instantly activated and configured, with servers added to or removed from the balancing pool on-demand with little or no downtime.
