Conclusion
While other applications such as databases, analytics, and virtual desktops can benefit from acceleration techniques, TPCe-
like workloads present the biggest challenge, and HP SmartCache succeeds. The characteristics of TPCe—more read traffic
(88%) than write traffic (12%) and repetitive data requests—allow HP SmartCache to enhance performance while
significantly reducing your storage costs.
Other types of workloads may not benefit from HP SmartCache, including those with the following characteristics:
• Non-repetitive I/O – Applications that do not access data multiple times over a period of time will not benefit from HP
SmartCache. Examples include routine backups, as they only accesses every file once, and disk benchmark utilities, as
their disk access patterns are typically random.
• Write-heavy I/O – Applications which perform predominantly write traffic versus read traffic will not benefit from HP
SmartCache. While database volumes benefit from HP SmartCache, database logging volumes will not benefit from HP
SmartCache because the majority of traffic to these volumes is writes to the hard disk drives.
HP SmartCache is the cost-effective, scalable, high-performance solution for accelerating data access for multi-terabyte
data sets for either DAS or SAN environments.
