Increasing the blocksize to 1024k achieved 284MB/sec uncompressed with amtapetype
Have not changed kernel module (st) parameters or anything like that yet Currently looking at the HP Library & Tape Tools ... it seems to want to test with blocksizes of 32k-128k only.... ------------- David Simpson - Senior Systems Engineer ARCCA, Redwood Building, King Edward VII Avenue, Cardiff, CF10 3NB David Simpson - peiriannydd uwch systemau ARCCA, Adeilad Redwood, King Edward VII Avenue, Caerdydd, CF10 3NB simpso...@cardiff.ac.uk +44 29208 74657 -----Original Message----- From: owner-amanda-us...@amanda.org <owner-amanda-us...@amanda.org> On Behalf Of David Simpson Sent: 28 September 2021 21:38 To: Luc Lalonde <luc.lalo...@polymtl.ca>; AMANDA users <amanda-users@amanda.org> Subject: RE: LTO8 tape profile - amtapetype Thanks. I noticed your blocksize... I may need to experiment more with that. So far I've not been able to turn drive HW compression off... though I'm happy to use it in production as opposed to software compression. ------------- David Simpson - Senior Systems Engineer ARCCA, Redwood Building, King Edward VII Avenue, Cardiff, CF10 3NB David Simpson - peiriannydd uwch systemau ARCCA, Adeilad Redwood, King Edward VII Avenue, Caerdydd, CF10 3NB simpso...@cardiff.ac.uk +44 29208 74657 -----Original Message----- From: owner-amanda-us...@amanda.org <owner-amanda-us...@amanda.org> On Behalf Of Luc Lalonde Sent: 28 September 2021 20:58 To: AMANDA users <amanda-users@amanda.org> Subject: Re: LTO8 tape profile - amtapetype External email to Cardiff University - Take care when replying/opening attachments or links.
