Hi Rick,

We Have th e same problem :-(, in my environment we got 10 TSM servers and
more than 3000 clients and more that 1.3 PTB of data in the Pools
And because we use  Datadomain 0.5 PTB it in the DD, and its increase the
Price, (When the DD is 40TB occupied), never the less IBM told me if I will
use IBM Dedupe
The will charge only for the size of the Dedupe Pool, I think all the lic by
TB its not correct for us because I need to pay for 400 TB more because of
the DD

amos

Ian,
Our company looked into it and thought it may save some $$ and at the same
time simplify the OVERLY complex PVU license model used for TSM/IBM.

I'll start by saying to make sure you understand what TSM products are
included in the "capacity" license proposal. From memory I don't remember
the exact ones but it does not apply to all TSM licenses. This obviously
means that the capacity license model may be attractive to some and
unattractive to others. Your IBM rep should be able to clarify this.

Also, in our environment we use a Data Domain backend which as you may know
prefers all incoming data to be uncompressed and unencrypted. Since the TSM
servers have no knowledge of the DD processes it reports the raw storage
numbers before compression and deduplication which negatively affected the
capacity licensing pricing.

We opened discussions on this issue with IBM but they refused to budge or
negotiate an adjustment for the "actual" storage used. Needless to say that
position was not too warmly received and we 86'ed the whole discussion.

Interestingly, had we used IBM storage/deduplication on the backend they
would use the actual storage, but no such provision for Data Domain.

Good luck....

~Rick

Hi,

We are in the midst of discussions on moving to capacity-based licensing
from the standard PVU-based method for our site. We have a large number of
clients ( licensed via TSM-EE, TDP agents, and on client-device basis
) and around 1PB of primary pool data. As I understand it, there is no
published metric for the conversion from PVU to per TB licensing so I would
be really interested and grateful if anyone would like to share their
experiences of that conversion in a private email to me.

Many thanks in advance.
