A: SmartCache is generally supported on P-series Smart Array controllers (e.g., P410, P420, P822, and Gen10/11 P-series controllers).
The technology is designed to be seamless. It requires no changes to your operating system or applications and is managed entirely through the HPE Smart Storage Administrator (HP SSA) tool. You can think of it as an intelligent traffic controller that ensures the most important data always takes the fastest possible route through your server storage infrastructure.
Getting a license key today can be challenging as these servers age: Product Numbers: Common SKU numbers for the license include (Single Server Physical License) and (Electronic License). Activation:
Enterprise servers face major storage bottlenecks as CPU core counts scale up. While traditional mechanical hard drives offer economical, high-capacity bulk storage, they lack the Input/Output Operations Per Second (IOPS) required for high-density modern computing. HP SmartCache architecture is built on three key elements: hp smartcache license key top
SmartCache features vary based on the server generation and controller models: Feature / Metric Gen8 (e.g., P420i) Gen9 (e.g., P440ar) Gen10/Gen10 Plus (e.g., P408i-a) Dedicated Key Required Dedicated Key Required Integrated / No Key Needed Max Cache Capacity Up to 2 TB Up to 4 TB Controller Memory Bound RAID Cache Support RAID 0, 1, 5, 6 Advanced Mix Modes Minimum FBWC 1 GB or 2 GB FBWC 2 GB or 4 GB FBWC 2 GB / 4 GB Energy Pack
If you meant a specific piece of software or different hardware, please clarify the exact , controller model , and where you saw “top.”
By storing frequently accessed "hot" data on a fast SSD cache, the system can serve that data instantly without waiting for mechanical hard drives to spin up and seek. This results in massive reductions in latency and significant improvements in IOPS (Input/Output Operations Per Second). A: SmartCache is generally supported on P-series Smart

It's important to note that on some newer, high-end controllers, the SmartCache feature may be included at no extra cost. A key exception is the . If your server is equipped with this specific controller, HP SmartCache is a standard feature and does not require a separate license key. Always check the documentation for your specific controller model to confirm the licensing requirements.
This article explores the "Top" things you need to know about the , from what it actually enables to how you acquire and manage it. You can think of it as an intelligent
: A portion of the controller’s hardware Flash-Backed Write Cache (FBWC) dedicated to tracking data blocks and cache hits.
Data-driven enterprises require rapid storage performance to keep up with demanding workloads. HP SmartCache, a controller-based read and write caching solution for HP ProLiant Gen8 and Gen9 servers, addresses this need by caching hot data onto high-speed Solid State Drives (SSDs).
Apply the license key using the following syntax (replace X with your slot number and XXXX-... with your key):
