Data transfer from Huawei NAS to another vendor

Publication Date:  2014-11-28 Views:  70 Downloads:  0
Issue Description
Customer wanted to know how to transfer a large amount of data , 250 TB , from Huawei NAS , N8500 with a back-end storage to a EMC Isilon NAS . 
Solution
Although initially we tried using the LUN COPY feature , it seems that files stored on the NAS keep the same tree configuration as in the VxFS although the LUN Copy functions at the block level and the EMC NAS would not have been able to see them properly. The only solution what we could think of was to use a host as an intermediary and map both LUNs from one storage and from the other and then copy files just like that . This could work if the bandwidth was large enough.
