擷取dell technical guide :
4.4.1 Non-Volatile Cache
Dell PERC controllers with Non-Volatile Cache (NV Cache) use the standard battery as contained in the Dell PERC controllers with battery back-up (BBU). The difference is in battery implementation:
�h *The battery in the BBU offering retains the data in cache in the event of a power cycle for a guaranteed period of 24 hours (typically up to 72 hours).
�h *The battery in the NV Cache offering will transfer the data from cache to flash in the event of a power cycle, where the data will be retained for up to ten years.

想請問1G NVC版本到底要不要接電池(BBU) ? 如果不接會有哪些問題 ?

謝謝
