Note: For some controllers like the P822, SmartCache may be included, but for most, a license is required. Frequently Asked Questions (FAQ) Can I evaluate HP SmartCache before buying? hp smartcache license key top
If you are running HPE ProLiant Gen10 servers, you will likely use the standard SmartCache license. However, with the introduction of ProLiant Gen11, HPE has streamlined some licensing models. Always verify that the license part number you are purchasing matches your controller generation. The standard part number for many years has been `R0M
: Historically, HPE offered a 60-day free trial key to evaluate the technology without data loss risks. Controller Compatibility
The HP SmartCache license key is a unique code that activates the SmartCache feature on compatible HP storage systems. This key is essential for enabling the software to operate at its full potential, unlocking all features and benefits of the SmartCache technology. The license key ensures that users can legitimately access and utilize the advanced caching capabilities, thereby optimizing their storage system's performance. If you are running HPE ProLiant Gen10 servers,
: Standard Mechanical HDDs hold the bulk volume. Accelerator : High-speed SSDs host active data blocks.
: Allows multiple licenses to be activated using a single key, ideal for mass deployments.
An unlocks a high-performance, controller-based storage caching solution that dynamically accelerates workloads in Direct Attached Storage (DAS) environments. By caching frequently accessed "hot" data onto low-latency Solid State Drives (SSDs), this technology bridges the speed gap between traditional hard disk drives (HDDs) and high-speed data processing units. What is HP/HPE SmartCache? The standard part number for many years has
One license is required for every server where the feature is deployed. A single server license can cover multiple Smart Array controllers within that same physical chassis, but it cannot be shared across different servers.
The primary, high-capacity pool of standard HDDs where all data permanently resides.
: Implementing HP SmartCache can lead to cost savings by maximizing the utilization of existing storage infrastructure. It enables businesses to get the most out of their current hardware without the need for expensive upgrades.
Run the following command in the HPE SSA (Smart Storage Administrator) CLI: ssacli ctrl slot=0 show config detail Look for "Controller Serial Number" or "Controller Board ID."
While HPE often provides a "Free 60-day Trial" key pre-loaded or available for download to let you test the performance gains, permanent usage requires a purchased license.
