　　Soultion:
　　-----------------------
　　Any of the below KBs or Communities threads may be>should always be DNS! Check this first and resolve any issues before delving further into support and troubleshooting.
　　While looking for causes I found these possibilities:

• 　　Not enough space in the datastore
  
• 　　Port 901/902 not open between the VI Client to the source of the file (and/or VC Server, could not find if that is also a factor)
  
• 　　DNS configuration for the host servers
  
• 　　As a possible solution I also found that restarting the VC Server service could help.
  

　　My Personal Solution:
　　--------------------
　　Since i used wireless to download the data from store, then i try to connect the ESXI via vsphere client, but failed.
　　Then i check DNS, it is ok, i can ping thenm via Netbios name
　　The problem is why i can't login Exsi host server via vsphere client?
　　then i plug the cable, it is works. i don't know why
　　So the solution is:
　　useing cable to connect the client computer to network and download,
