Fusion-io: Not All Caching is Created EqualPosted
Within a data network, what difference does it make where the decision to cache data is made? If it is a virtualized environment, it makes a significant difference.
Virtualization has completely changed the way compute resources are deployed, utilized, and managed. While this change has delivered significant benefits, it has highlighted that spinning disk is simply too slow to adequately deliver data quickly enough to virtualized applications in order to keep the compute processors working at optimal throughput. As a result, the marketplace is becoming crowded with “Caching” solutions. These solutions generally take the form of
- External SSD in Disk Arrays
- Caching Appliances
- Caching Software
- Intelligent, Application Level Caching
