#12:So why clustering?
Down-time is a luxury that no enterprise has these days. Work-shifting and IT globalization translate to users being online 24/7. Traditionally, to get more capacity, older hardware had to be replaced for more new units. Unfortunately, not only there is a high cost associated with swapping old units for more powerful hardware time but also and money invested in the logistics to plan and test such activity.
Hardware upgrades are very costly and disruptive!
With the increasing capacity demands, there is even a bigger chance that this has to be repeated quicker than expected.
When implementing a clustering, you can:
1. Increase the efficiency by using idle resources. This immediately addresses any scalability requirements. (CLICK)
2. Add capacity as needed to satisfy any throughput requirements by scaling out to 32 units acting as a single logical appliance (CLICK)
3. Simplify administration (CLICK)
4. Eliminate downtime by providing a highly fault tolerant solution alternative to an HA pair (CLICK)
5. Ensure there is no network downtime
