首先说明一下，我没接触过emc的东西！
下面这些是我看emc cx600文档中的语句：
If ac power fails, an SPS provides backup power until the storage processor has flushed its write cache data to the DAE2 disks. The SP then shuts off SPS power.

是不是cx600的spe中没有硬盘啊？如果是的话，上面所说的，掉电后写cache数据到DAE2中就可以理解。如果spe中带硬盘的话，是不是就没法理解了？我所知道的是掉电后写cache到它系统盘（前五块盘中）。

DPE (disk processor enclosure)
A type of storage device that includes SPs, power supplies, cooling modules, and disks in a single enclosure. In most cases, a DPE can support its own integrated disks and one or more DAEs. Each DAE is designed to work with a DPE. A DPE differs from an SPE like the CX600, which holds no disks but connects to 15-disk DAE2s.


SPE (storage processor  enclosure)
A storage device that includes an enclosure, SPs with host I/O ports,
back-end disk ports, and power supplies.

唉，emc的概念真多啊！发上来给和我一样刚开始学习emc的兄弟们了解一下吧。
不算发贴骗积分吧？
