Hi all,
At the moment, the inter-Tier2 transfer tests are starting up. If any of
the dCache sites are finding it difficult to sustain the target rate
(particularly for writes) then I would recommend changing the parameters
for the dCache pool selection mechanism in the following way.
1. Login to the admin interface (either command line or GUI)
2. cd to the PoolManager cell in the dCacheDomain.
3. Issue the command:
set pool decision -spacecostfactor=0 -cpucostfactor=1
4. save
5. Exit the interface
Setting the space factor to 0 essentially means that you don't care on
which pools the incoming data will end up (assuming that you have
multiple write pools available).
More information can be found here:

Hope that helps. Let me know if you have any questions.
Cheers,
Greig
