I read that I should turn it off, but Dell has no answer
For me on how to do so. The guys I talked to thought I
Was crazy and they had never heard of such a request.
This tape drive is supposed to have some "intelliget"
Sensors to determine if it should turn compression on or
Off.
The main reason why hardware compression should be off, is because most tapedrives blindly apply the compression algorithm to any data. It is a know fact that this INcreases already compressed data.
However, recently we found out (by using amtapetype) that some recent LTO drives have some more intelligence built into them, and detect when or when not to do hardware compression. The result is that even if you feed it already compressed data, the capacity on tape is optimally used, even with hardware compression.
You could even argue that in this case you better have hardware compression on, so that you can have some DLE using software compression (to lower the network bandwith) and mix with some other DLE's without software compression (to avoid the cpu-load). You can have the cake and eat it too.
- Turn off compression - Get a more accurate tapetype definition?
amtapetype -e 100g
is still the best way to get your tapetype.
