User Manual for LB-8000

1. LB-8000 Overview

LB-8000 L4 Server Load Balancer is a high performance layer 4 switching device that enables enterprises and ISPs to load-balance all IP-based applications and to create a High Availability (HA) web environment.

Powered by dual Xeon™ processors and equipped with Gigabit Ethernet NIC, LB-8000 is best suited for web sites or other IP-based applications with intensive traffic volumes. Direct routing mode makes sure that LB-8000 will not become the bottleneck of heavy traffic applications such as FTP or streaming.

LB-8000 is specially designed for web environment that cannot afford downtime. Embedded OS greatly enhances the reliability of LB-8000. Server health check is constantly done by LB-8000 to ensure no packet is forwarded to crashed servers. In addition, the cost of failover is minimized by ultra high-speed failover and bi-directional stateful failover. Heartbeat signals are going through both network and serial cable to prevent unnecessary failover and active-active problem.

LB-8000 is simply the best choice of server load balancers that helps you easily maximize the performance and availability of your web system at minimal costs.

1.1. Benefits

Super High Availability

LB-8000 constantly checks the server status to make sure no request from users is forwarded to malfunctioning servers. Graceful shutdown ensures no connection gets lost when users take down servers for maintenance. Moreover, the cost of failover is minimized by high-speed failover and bi-directional stateful failover. Finally, features such as Nice Fail Back or Dual-path Heartbeat effectively reduce failover costs.

Ultimate Performance

Dual Xeon processors with Hyper-Threading technology provide LB-8000 with ultra fast performance compared to other L4 switches. With Hyper-Threading technology, processor-level threading can be utilized which offers more efficient use of processor

User Manual for LB-8000 R2.6.2

PLANET Technology Corp.

resources for greater parallelism and improved performance on LB-8000. Besides, Gigabit Ethernet network interface gives LB-8000 maximum network capacity. Finally, for applications with huge traffic flows such as FTP or streaming, LB-8000 also supports direct routing mode to allow streaming or data flows sent back to clients without going through LB-8000.

Unlimited Scalability

LB-8000 does not put limitation on the number of clusters (a.k.a. VIP) and also the number of real servers. System admin does not need to pay extra license fees to scale the system.

Manageability

System admin can easily manage LB-8000 through Web GUI or CLI. The bi-directional sync function makes sure that configurations and logs are always the same between two LB-8000. In addition, with LB-8000, system admin can easily monitor the status of real servers through GUI. Also, system admin can manage contents in real servers through IP forwarding or VPN mechanism. Finally, email alert and SNMP trap makes sure that system admin gets informed as soon as system fault happens.

Cost Effectiveness

Not only is LB-8000 a cost-effective choice but it also helps your business avoid the possible loss due to the system downtime. Also, LB-8000 makes sure that all servers are working at full capacity, which further saving the cost of buying extra servers.

1.2. Features

Load Balancing for most IP-based Applications

LB-8000 can load-balance most IP-based applications, such as web, email, FTP or streaming. You can also apply LB-8000 to other enterprise applications that have web-based GUI, including IBM WebSphere, Cold Fusion, BEA WebLogic Servers and Sun iPlanet Servers and so on.

Multiple Load Balancing Methods

LB-8000 provides both static and dynamic modes for load-balancing servers. Static modes

User Manual for LB-8000 R2.6.2

PLANET Technology Corp.

contain round robin and weighted round robin. Dynamic modes include least connections and weighed least connections.

Flexible Network Configurations

LB-8000 supports NAT (network address translation), direct routing and IP tunneling configurations. System admin will be able to choose the appropriate configuration according to the applications and environment.

Server Health Check

LB-8000 regularly checks the status of each server to make sure no traffic is forwarded to the malfunctioning ones. The health check includes ARP Check (Layer 2), ICMP check (Layer 3), port check (Layer 4) and content check (Layer 7). System admin can freely define which level of health check to do.

Graceful Shutdown

The DISABLE feature helps you to take off a working server without losing any connection. LB-8000 will signal system admin when all transactions on a particular server are finished.

Redundancy of LB-8000

Active-standby mode eliminates the single point of failure. Also, fast network-based failover through heartbeat minimizes the costs of failover.

Bi-directional Stateful Failover

Real time synchronization between primary and backup LB-8000 ensures that two load balancers keep the same information about TCP connections and persistence. This state mirroring function, also called stateful failover, guarantees that no TCP connections or persistence information get lost during failover. Moreover, LB-8000 makes stateful failover bi-directional, which means stateful failover applies no matter the failover happens from primary to backup or vice versa.

Nice Fail Back

With Nice Fail Back, backup LB-8000 will become primary after failover happens. That way, even if original primary LB-8000 recovers afterwards, failover will not happen again. This feature can reduce times of failover and raise the availability of system.

Dual-path Heartbeat

User Manual for LB-8000 R2.6.2

PLANET Technology Corp.

Heartbeat signals between two LB-8000 are sent through both network and serial cable. Failover will not happen until backup fails to get the heartbeat signals from primary through both routes. This feature prevents unnecessary failover and avoids the problem that two LB-8000 are trying to become active (master) due to the network failure.

Synchronization of Configurations and Logs

Bi-directional sync function makes sure that primary and backup LB-8000 always keeps the same configurations and logs.

Superior Reliability and Stability

Embedded operating system provides superior reliability and stability.

Active/Passive FTP Support

LB-8000 put special efforts on FTP application. No matter active or passive FTP, in NAT or direct routing mode, LB-8000 makes sure that FTP data session goes to the same real server with FTP control session and the load can be still balanced.

ECOM Protocol

ECOM protocol makes sure the persistence is still valid when e-commerce visitors are going to SSL pages from normal web pages.

Sticky Connections

For session-based applications, to keep the integrity of session data, LB-8000 can always forward the traffic from the same IP address to the same real server.

Real Time Status Monitoring and Statistics

Through a Java Applet-based monitor, system admin can monitor the status of LB-8000, real servers and network in a real time basis.

Network Interoperability

Static route, DNS proxy and outbound NAT provide system admin maximum flexibility to fit LB-8000 into existing network environment.

Detailed Logging

User Manual for LB-8000 R2.6.2

PLANET Technology Corp.

LB-8000 provides detailed logging function for system, management, HA, connection and alert. System admin will be able to export log data and also monthly summary report will be sent by emails.

Email Alert

When LB-8000 or real servers fail, system admin will be informed through an alert message.

SNMP Support

LB-8000 provides its enterprise MIB and will send out TRAP messages to SNMP manager when necessary.

APC UPS Support

LB-8000 can work with APC UPS to be shutdown safely while a power problem suddenly happens on site.

Security

IP masquerade protects real servers from being exposed to Internet directly. SSH/Base64 allow system admin to manage LB-8000 safely.

GUI/CLI User Interface

System administrators can manage LB-8000 through both GUI (Graphical User Interface) and CLI (Command Line Interface).

1.3. Using LB-8000 documentations

There are two documents, Administration Guide for LB-8000 and User’s Manual for LB-8000 that will provide all information on how to work with the LB-8000 machine. The detailed usages of each guide are described in the following sections:

LB-8000 Own Router Own Router

After you determine the network model and install the LB-8000 into your network environment, then you are ready to configure LB-8000.

LB-8000 has default IP address on its network interface:

l Network 1 Interface (eth0): 192.168.2.1 l Network 2 Interface (eth1): 192.168.3.1

So, when you finish the hardware installation, boot up LB-8000 and ready to configure LB-8000, we suggest you to add an alias IP that is in the same IP class on you client. For example, you can add an alias IP 192.168.2.115 which is the same IP class (192.168.2.xxx) as network 1 interface of LB-8000 on your client.

Here are the sample procedures to add an alias IP for Linux and Windows 2000 Professional.

5. Configure Network Environment and a Cluster

The LB-8000 stores a server list with services provided by LB-8000. The LB-8000 also dynamically updates this list to ensure that the resource of the whole cluster is being utilized. This dynamically checking process ensures that workload has been distributed to the servers with a fully usage. Also, LB-8000 provides the cluster service in Network Address Translation (NAT), Direct Routing (DR), and IP Tunneling configurations. Particularly in the NAT setting, a LB-8000 serves as the local router with which more protections are added to the local network.

5.1. NAT (Network Address Translation)

NAT is a method to translate the addresses in both outgoing and incoming datagram. NAT procedure for cluster management is usually the best method for protecting the network from intrusion since LB-8000 can act as a router and firewall between WAN/LAN to send requests and response between real servers and clients. The whole network can be represented with just one real IP address. (See Figure 5-1)

For configuring a cluster in NAT mode, you should setup following information:

l The cluster type l The virtual host name l The virtual host IP address l The netmask value l The service type l The service port number l The persistency setting l The load distribution schedule. We support four types of schedules:

n Round Robin n Weighted Round Robin n Least Connection

n Weighted Least Connection l Add real server list l The health check method. We support:

n Content check for HTTP/HTTPS

n Port check

n ICMP check

5.3. Direct Routing

The virtual host IP address is shared by the real servers. LB-8000 also acts as a load balancer. LB-8000 has a virtual host configured interface, which is used to accept and route request packets to the chosen servers directly. The real server processes the requests and sends the reply directly back to the client. LB-8000 performs direct routing technique allowing servers to send responses straight back to the clients without going through LB-8000. (See Figure 5-2)

For the definition of Direct Routing, please refer to Administration Guide for LB-8000.
