Hello,
this is my first posting to this list.
A customer of us has a NetApp 3020 with 3 S-ATA shelfes each filled with 500 GB disks. He has a trunked 2*1 GBit network connection.
He has 3 volumes, each volume resides on a different aggregate built from the disks of one shelf each.
Via NFS he gets a perfomrance of sustained 60 MB per second with large and small files. Only one connection used during the test, no aditional traffic on the system and network segment. He expected the performance to be "much" better.
Besides any possible calculations - what´s the performance he can expect in real world practice under best circumstances?
