Hi everybody.
i have a fas2020 in active/active mode with 12 sas 15k disk (1 spare, raid dp) mainly for san usage and 10 sata 7200 (1 spare, raid dp) for nas usage.
The fas2020 is connected with two 1gb network link in lacp mode on cisco 2690G.
I'm running 7.3.5.1 data ontap version.
With differents volume on each type of disk, via cifs, from a computer connected on the same switch, i never had more than 50-55mb/s on reading from fas2020.
The sysstat -xsu 1 give me :see attached file
I tried with a direct connexion (twisted cable) between fas2020 and a computer, no more than 50Mo/s in reading from fas.
I ran reallocate each night on each volume.
I tried on a new volume, freshly reallocated, with on 4gb file, same throughput.
The network interfaces are not fully used.
Between two server on the same swith i copy file server to server at 110mb/s with a 1gb connexion, so the switch can manage more throughput that i have.
Is it normal to have no more than 50-55mb/s on a fas2020 ? I have 90-100mb/s on a small buffalo nas which cost 500€ !
Is there something wrong in my config ?
thanks for your answers
Nicolas
