[Gluster-users] Newbie: Exploring Gluster for large-scale deployment in AWS, large media files, high performance I/O

is it 380MB in read or write ? What level of redundancy do you need?
do you really need nfs stack or just a mount point (and so be able to use
native gluster protocol) ?

Gluster load is mostly put on clients, not server (clients do the sync
writes to all replica, and do the memory cache)
