I went ahead and set the estcap to 10g.. Which it really depends on what
your looking for if you leave it at 0 then you will get the current
capacity that was written to tape. Most everything I do is compressed at
the client side. So I only see the 10g max.

Thanks Ron and Jim.  One more question for Jim.. What estcap and maxcap
values do you use for your 3590 device class and what if the storage pool
using the device class contains a mixture of data compressed on the client
and data not compressed on the client? Thanks again

It depends on where you do your compression.. If you do it on the client
side then ADSM will report 10g per tape. If you use hardware compression
and not client compression then ADSM will report 30g per tape.. We are
getting 9187.6 mb per tape.

  We are adding Magstar drives to our MVS system for use with our ADSM
v2.1.10 MVS server.  I'm not sure what values to use for estimated capacity
and/or maximum capacity, 10GB? 30GB?, when defining the device class for
the 3590s.  Can anyone using 3590s with ADSM let me know what values you
selected?  Also are there any other 3590 related issues I should be aware
of with ADSM for MVS or MVS in general?  We are installing the 3590s in a
4410 STK silo.  Thanks
