• Advanced Application Delivery (ADC) and security optimization features like content switching,
caching, compression, intrusion prevention, SSL acceleration and native support for Microsoft Exchange
2010, Lync, SharePoint and Terminal Services make the LoadMaster™ the ultimate Investment
Protection Appliance.
Cost Containment:
• With a cost effective starting price, the LoadMaster™ is a clear value leader of purpose built server
load balancing and application delivery appliances.
• Comprehensive Hardware
maintenance and support is included for the first year with every LoadMaster™ model, further lowering
the cost of acquisition and TCO.
• Unlike most competitors that offer key features and functionality as extra cost options, KEMP includes
the most comprehensive feature set in the industry in its base price –even further lowering TCO.
• With low power consumption models, the LoadMaster™ contributes to cost savings associated with
energy usage and cooling requirements.
Ease of Use:
• All LoadMasters come with an intuitive and easy to use Web User Interface (WUI), enabling
administrators, even without prior load balancing experience, to easily set-up, configure and maintain
their LoadMaster™ appliance.
• The LoadMaster™ easily integrates with existing network infrastructure products such as switches,
routers and firewalls, eliminating the need for complex and time consuming implementations and
system reconfigurations.
• With secure SSH and HTTPS WUI remote access, real time performance and availability displays and
SNMP support for event traps & performance metrics, the LoadMaster™ can easily be managed
remotely and integrates with existing network management platforms.

LoadMaster™ GEO
Disaster Recovery
Multi-site Load Balancing
Location Awareness
LoadMaster™ GEO (GLM) offers the ability to move past the single datacenter, allowing for multi
datacenter load balancing and high availability. GLM ensures that even when a primary site is down,
traffic is diverted to the disaster recovery site. LoadMaster™ GEO also includes the ability to ensure
clients seamlessly connect to their fastest performing and geographically closest datacenter.
The LoadMaster™ GEO offers the same management interfaces as KEMP’s Server Load Balancer
(LoadMaster™) hardware appliances, including all the foundation
technology such as syslog logging, email notifications, interface bonding, and Gigabit support.
LoadMaster™ GEO provides advanced application health checking, to ensure that unavailable services or
datacenters are not visible to clients. Health checking can occur at the services level or even the site
level, allowing for flexible decision making on when traffic should be diverted per Fully Qualified Domain
Name (FQDN).
LoadMaster™ GEO offers “Round Robin” load balancing for all active datacenters, which includes
support for weights and a chained failover option for disaster recovery. LoadMaster™ GEO securely and
seamlessly integrates with LoadMaster™ to offer “Real Server Load” load balancing, in which
LoadMaster™ GEO uses local datacenter metrics provided by LoadMaster™, allowing clients to connect
to the least busy datacenter. Added to this is location awareness of your clients which results in your
clients being redirected to the most appropriate datacenter based on their location.
LoadMaster™ GEO can be deployed in a distributed (Active/Active) high availability configuration, with
both appliances securely synchronizing information. Introducing LoadMaster™ GEO in your existing
Authoritative Domain Name Services (DNS) requires minimal integration work and risk, allowing you to
fully leverage your existing DNS investment.
LoadMaster™ GEO is easy to set up, and easy to manage. LoadMaster™ GEO is a self-contained ‘plug and
play’ appliance that doesn’t require the additional installation of software on your servers. Network
management is made easy, administrators can deploy new servers and take individual servers offline for
routine maintenance without disrupting services to end-users. Integrating the LoadMaster™ GEO into an
existing DNS infrastructure can be done with no service impact and allows for distributed
administration.
Specifications v6.0*
High Availability & Reliability
LoadMaster™ GEO helps prevent service outages by quickly detecting server and datacenter failures and then directing traffic.
Monitoring and load balancing are based on layers 3 and 4 of the Open Systems Interconnection Basic Reference Model (OSI).
Included in HA is the ability to have two appliances, protecting against introduction of a single point of hardware/network connectivity
failure. Each individual LoadMaster™ GEO can also be configured to provide network link-layer redundancy.
Location Awareness
The GLM can determine the location of a client in real time and direct them to the most appropriate datacenter based on this
location resulting in intelligent redirection of clients.
Speed
LoadMaster™ GEO’s intelligence ensures that your mission-critical servers are continuously available and performing reliably.
LoadMaster™ GEO can monitor server and application load. This information is then used to intelligently direct user requests to the
cluster that is most available. By intelligently redirecting traffic, LoadMaster™ GEO eliminates server overload conditions and round
trip propagation delays that may slow performance, allowing you to increasing end-user application speed.
Scalability
LoadMaster™ GEO solves the scalability “dilemma” by continuing to support increasing network server workloads and still providing
high reliability. LoadMaster™ GEO offers:
Intelligently distributes traffic across server arrays or data centers, reduces the need for increasingly larger and more expensive
servers to accommodate increases in network traffic and enables many inexpensive servers to function as a single, virtual server.
Reduces the single point of failure and expense inherent with a single large server, and allows for the orderly addition of new
servers, or the routine maintenance or upgrades of servers without disrupting service to the end user.
Can be used with multiple heterogeneous hardware platforms

Microsoft® Lync™ ushers in a new connected user experience transforming every communication into an
interaction that is more collaborative, engaging, and accessible from anywhere. For IT, the benefits are equally
powerful, with a highly secure and reliable system that works with existing tools and systems for easier
management, lower cost of ownership, smoother deployment and migration, and greater choice and flexibility.
Microsoft Lync Server 2010 communications software and its client software, such as Microsoft Lync 2010, enable
the end users to connect in new ways and to stay connected, regardless of their physical location. Lync 2010 and
Lync Server 2010 bring together the different ways that people communicate in a single client interface.
An enterprise high available deployment of Lync Server requires deploying multiple servers in Front End pools,
Director pools, and or Edge Server pools, Load balancing is necessary when using multiple servers in a pool and a
Load Balancer distributes the traffic among the servers.
Microsoft Lync Server 2010 supports two load balancing solutions: DNS load balancing and hardware load
balancing. You can choose different load balancing solutions for each pool in your deployment. Hardware load
balancers are also required to provide load balancing for the internal and external web services when DNS load
balancing is used.
The KEMP LoadMaster™ combines versatility with ease-of-use to speed deployment of the complete portfolio of
advanced messaging applications and protocols used by Microsoft Lync Server 2010. Layer 7 health checking at the
LoadMaster™ ensures that should one of the servers become inaccessible, the load balancer will take that server
off-line, while automatically re-routing and reconnecting users to other functioning servers.
The entire KEMP LoadMaster™ product family, including the Virtual LoadMaster (VLM) supports Microsoft Lync
2010, and includes a comprehensive first year warranty and technical support agreement.
