这种说法客户肯定是不认可的， 容量相差太大，分析如下： 存储层面：SSD可用总空间为30986 chunklet（Used-OK）+7630（Unused-Free） chunklet =38616 chunklet，折换SSD_R6 SSZ=6为32180chunklet，扣除划分出去的31T*1024，剩余未划分426chunklet，即当前给VMware使用的chunklet数目为7630-426=7204G 客户环境：31T SSD的硬盘，剩余2.92T=2990G 可能原因： （1）实际使用以VMware剩余空间为标准，VMware文件系统即使满了，存储仍有空间，但在VMware放置超过3T的文件，VMware环境是否会出现问题尚未可知，建议客户联系VMware厂商询问是否之前出现过与3par对接识别不准确的案例 （2）怀疑是VMware文件系统识的原因，或者是由于划分出去的vv是tpvv，VMware侧也做了类似精简置备的分配（分配空间57.82T），相当于双精简，是否两者之间在识别上存在偏差
