Hi everyone (apologies to those who get this twice),
I am going to attend a meeting next week [1] that will discuss how the SRM
2.2 storage classes should be implemented at Tier-1 and -2 sites (i.e.
if any special configuration of the SRM and storage hardware is needed
beyond what is already deployed). For those who haven't heard of the
storage classes before, they can be summarised by the terms:
Tape1Disk1
Tape1Disk0
Tape0Disk1
which represent how the LHC experiments want to be able to store and
manage their data.
In the UK, Tape0Disk1 will likely be the only one to affect the Tier-2s.
Jeremy suggested that I ask for input from people before the meeting so
that we can ensure all relevant issues/concerns are raised. Does anyone
have any questions that they would like me to raise on their behalf? The
meeting is on Tuesday afternoon.
Cheers,
Greig
