Use NetApp Flash Cache intelligent caching and capacity-optimized drives to improve storage performance and efficiency.

Key Points

  • Use for random read-intensive workloads (databases, e-mail, file services).
  • Reduce latency by a factor of 10 or greater compared to hard disk drives.
  • Increase I/O throughput and eliminate performance bottlenecks.
  • Lower costs—use SATA drives with Flash Cache for important workloads.
  • Save power, cooling & rack space by using fewer, larger hard disk drives.
Overview

Add NetApp® Flash Cache controller-attached PCIe intelligent caching instead of more hard disk drives (HDDs) or solid-state drives (SSDs) to optimize your storage system performance.

Flash Cache speeds data access through intelligent caching of recently read user data or NetApp metadata. No setup or ongoing administration is needed, and operations can be tuned. Flash Cache works with all NetApp storage protocols and software, enabling you to:

  • Increase I/O throughput by up to 75%[1]
  • Use up to 75% fewer disk drives without compromising performance[2]
  • Increase e-mail users by up to 67% without adding disk drives[3]

Intelligent caching and NetApp storage-efficiency technologies enable the Virtual Storage Tier, which promotes hot data to performance storage in real time without moving data.
