Iam planning to setup a storage which needs to be located in 5 geographical locations. The data which i write on the first location should get sysnc with rest 4 locations in no time. I dont want to invest more in procure higher bandwidth solutions. Is there any other way to sync the data by caching mechanism or related to same technique. The ens result would not only the data sync I require the data to get video streamed or rendered using same applications on all location. I wont specifically select the data from locations. I just select stream or render what ever mount points I have. Cause I dont want to show the location to the end user. He will not come to know which location data he is accessing. But end of the day I require minimum 4GBps of throughput on each storage location. Will it be possible by just configuring same kind of storage hardware on all locations with same LUN size & file systems export. User will have access either through NFS or FTP. Does anyone have idea on this?

Thanks. We'll let you know when a new response is added.

It depend of your budjet, the SAN you buy or have and the distance between the location. for a 4Gbs trueputs it is verry expensive. You can use a Netapp appliance that enable De-duplication for synchrnising you files. also you can use Sunbelt Double-Take to synchronyse data between sites but this is a windows Soft it looks like you aer on linux/unix FS. so this is not a solution.

you can by WAFS (Wan aceleration file systems) I think this is the good meening. WAFS will replicate only deltas between to appliance. Cisco and HP hase verry good WAFS

Their is no cheap solution in this kind of solution. If your SAN is de-dup ready it can hel you but normaly thez are doing deduplication on backups file. but NetApps can do it online with non structured data.

Good look
