选择存储产品的时候，需要综合考虑：
1、投资；
2、对性能的要求；
3、对扩展性的要求等。
CX500是一款很好的存储系统，它的优点主要体现在管理性上面。比EVA3000的管理性更好。
EVA3000采用有COMPAQ一种新的虚..........

呵呵，HP都没敢说的您倒真捧场啊，到真想知道什么时候EVA可以支持
一个VRAID同时坏两块盘了。
The EVA Vraid technology is unreliable, i.e., #1: all drives are effected during a rebuild, #2: all RAID 0 data is lost even if only one disk fails, #3: two drive failures results in the loss of all RAID-5 data: Rebuttal: EMC simply doesn’t understand the technology. Where to begin? This is classic EMC FUD. A colorful chart, a few technical-sounding words, a square-jawed sales rep, two tickets to the Boston Garden and anything is believable. #1: the EVA divides its RAID-5 stripes into multiple smaller stripes of 4D+1P. If a disk fails in a RAID-5 group, then only those other four disks and one other disk at a time, is actually involved in the rebuild. #2: yes, if the customer chooses to use (striped but un-mirrored) RAID-0, then a disk failure in that RAID group, by definition, would result in data loss. This is not an issue with the EVA, this is an issue with RAID-0. Note: disk drives do fail, so RAID-0 should be used only in the rarest of instances and only when data loss is not a concern. #3: Yes, two drive failures in a RAID-5 group will result, by definition, in data loss. Once again this is not an EVA issue; it is a RAID-5 issue.
