The controller must be populated with an operational FBWC module (typically 1GB, 2GB, or 4GB). SmartCache will not activate or will operate in a degraded state without a healthy supercapacitor module.
Most HPE servers come with a temporary 30-day trial key. This allows you to benchmark performance gains. However, once it expires, your cache goes offline, and your array reverts to pure HDD speed. Optimizing Enterprise Storage: The Ultimate Guide to HP
: Data remains stored on the primary HDDs; a cache failure typically does not result in data loss because only a copy of the data exists on the SSD. Licensing Models
At its core, HP SmartCache is a controller-based, intelligent caching solution designed for Direct Attached Storage (DAS) environments. It functions by automatically identifying and caching the most frequently accessed data—often called "hot" data—onto lower-latency Solid State Drives (SSDs), while less frequently accessed "cold" data remains on traditional Hard Disk Drives (HDDs). The controller must be populated with an operational
Use SSA to monitor your read-cache hit rate. A higher percentage (e.g., >80%) indicates a well-configured cache.
