32 Chapter 2 Scalability and Availability Overview
Combining hardware and software clustering solutions
Instead of having to choose either a hardware solution or a software solution, you can
combine both types of clustering choices. Combining hardware and software solutions
certainly provides the greatest scalability and availability capabilities for a site. A
combined solution is an attractive option if your organization has already invested in one,
but is looking for more comprehensive coverage. Having the flexibility to integrate
hardware with software means that your organization won’t necessarily have to absorb a
capital loss on a previous technology investment if you decide to purchase additional
clustering technology.
However, as already discussed, all hardware or software solutions are not equal. Many
have different features and capabilities, and not all hardware and software integrate well
together. Investigate thoroughly when purchasing technology to augment your current
solution.
For a visual representation of hardware and software clustering solutions working
together, see
“Hardware-based clustering solutions” on page 29 .
