We've got an ageing IBM N6250, aka FAS3250 I think, running 7-Mode 8.2.1
We want to extract a lot of data from this filer using CIFS - we've got 200T+ in about 44 shares on a two headed controller.
Our problem is that the file copies just aren't going fast enough. Individually they work fine, and if I set off a copying job, it works well for a while. But it will then collapse - the transfers simply sit there waiting, being very slow indeed. 15 seconds to shift a 40K file.
The copying job is in powershell on a Win2016 VM, doing CopyItem \\filer\share\file destination. There is 10GbE between the filer and the VM.
What sort of things can cause that? I realise this is a vague question, so please ask me for further information and I'll try and supply it.
cheers,
