Troubleshooting and Support Common issues include license mismatch, expired or incorrectly applied keys, and failures due to firmware incompatibility. Troubleshooting steps:
The HPE Smart Array controller (e.g., P408i-a, P816i-a) is physically capable of performing SSD caching. However, HPE divides its feature set via licensing to deliver different tiers of value. Without the license key, the controller’s SSD caching feature remains dormant. The hardware is present; the firmware simply will not activate the functionality. Hpe Smart Cache License Key
Most HPE Smart Array P-series controllers across ProLiant Gen8, Gen9, and Gen10 servers support SmartCache, though the licensing requirements differ by generation. Server Generation Supported Controllers Licensing Status P408i-a, P408i-p, P816i-a Without the license key, the controller’s SSD caching
Supports RAID levels including 0, 1, 10, and 5 for the cache volume to ensure reliability. License Types and Part Numbers Key behaviors include:
: While read performance spikes, write latency can increase if the Flash-Backed Write Cache (FBWC) becomes full, as the controller must then wait for HDD writes to complete.
HPE Smart Cache is a caching software solution designed for HPE ProLiant servers. It uses intelligent caching algorithms to optimize storage performance, reducing the need for expensive storage upgrades. By leveraging flash-based caching, Smart Cache accelerates read and write operations, resulting in significant performance gains.
How Smart Cache Works Smart Cache operates transparently at the storage controller or host-controller level. Key behaviors include:
