Application Scenarios

Application Scenarios

This section introduces application scenarios of SmartCache. SmartCache is suitable for application scenarios where some random small I/Os are frequently accessed, and read operations are more than write operations. In such scenarios, SmartCache can greatly improve system read performance.

With SSDs' fast response speed and high IOPS, SmartCache remarkably improves system read performance. SmartCache is especially suitable for application scenarios where some random small I/Os are frequently accessed, and read operations are more than write operations. The scenarios include database, online transaction processing (OLTP), web services, and file service applications. Figure 1-4 shows application scenarios of SmartCache.
