Scaling up ZXTM

Many load balancers and traffic managers on the market are adequate at low traffic loads, but are unable to cope when demand for your services increases. As with all solutions from Zeus Technology, Zeus Extensible Traffic Manager (ZXTM) is designed to extract the best possible performance from your hardware, and to scale up easily in line with the demands of your business.

In real terms, ZXTM will outperform comparable offerings in many areas out-of-the-box, and can be scaled-up at a price point that will keep your budgetary controller happy.

How fast is ZXTM? 

For almost all traffic management applications, the answer is 'fast enough'.

For example, independent benchmarks performed by Broadband-Testing demonstrate that a single ZXTM running on standard dual AMD Opteron hardware can achieve:

Dual-core processors deliver twice the SSL and content processing power. This performance compares favorably with competing products nearly three times the cost, making ZXTM the most cost-effective option. Capacity can be grown linearly by scaling out the number of units.

If you have specific performance requirements, please contact info@zeus.com and Zeus will be happy to advise.

I need more than two units to manage my volume of traffic. Is this possible? 

Yes. ZXTM allows you to cluster as many front-end traffic managers as you require in fully-active or mixed active / standby clusters to ensure that your traffic management layer is not a performance bottleneck. Unique TrafficCluster™ scalability technology in ZXTM allows you to do this in a fault-tolerant setup without the constraint of having to pair units. ZXTM is easily configured from any unit (redundant administrative interface) and incoming traffic can be distributed intelligently across all the front-ends with only a single traffic IP address.

How will I know how many ZXTM units I will need? 

Sizing your ZXTM cluster appropriately for your current and future needs is best achieved by evaluation within your own network. This is because a wide range of variables will affect performance, such as:

ZXTM is available now for a free 30-day evaluation from our Download sections. Alternatively, our experienced team can help you to inspect your current traffic patterns and make an informed sizing decision.

Lastly, when in use, ZXTM itself can provide you with detailed real-time and historical traffic data which you can use to determine whether you will need additional traffic management units to increase your overall capacity.

What kind of performance can I expect from ZXTM appliances? 

As well as being available as stand-alone software, ZXTM is also available as a pre-installed and optimally-tuned hardware appliance. The ZXTM appliance is a high-specification rack-mounted unit based on AMD reference hardware. Full appliance specifications for ZXTM are available at our appliance information page. Typical performance information can be found above under How fast is ZXTM?.
