Which i have just written up, but I will upload to the usual location later.
And many apologies to Oxford's networks, once I got FF launched it worked brilliantly!
I think I got most of the ISGC summary summarised.
Many thanks for joining.
Cheers

Postponed since Santanu didn't join.
1. ... will include this document:
http://www.ogf.org/Public_Comment_Docs/Documents/2012-02/EMI-StAR-OGF-info-doc-v2.pdf
which is currently open for public comments:

Have OSG provided input into this?
The TEG has provided input to storage accounting. Needs to be
lightweight, and used by alls.
2. FTS discussion - there have been a number of threads on the list
(er, two) within the past week or so.

Sites are getting new internal networking - what do the graphs show,
does it reflect whether the network upgrade has had an impact?
These are from the RAL FTS. Inter-UK transfers. Also all sorts of
space tokens - could we move the data from
changeSpaceForFile/moveFile - currently actually copies. How much
changeSpaceForFile is implemented. It may also be a copy, because the
VO wants the file in two different space tokens? One of the copies
can be deleted. What is the case behind this? Sounds a bit like they
are trying to manage something which the SRM is supposed to do - but
doesn't.
Small file problem - comparing 90 MB with files which are 100K.
For the headnode you need the time for it to respond?
Lots of overheads, including possibly async.
Would it be useful for us to have the raw data?
3. Storage/data highlights from ISGC2012
Jens:
* iRODS workshop, installfest. Australia considering iRODS
(nationally).
* dCache - NFS4 demo, remotely mounting - showing movie using stock
linux kernel.
* Data - Johns Hopkins: "can do 150 TB in 10 days but lots of black
art", "can stream 1.2 GB/s off databases for science (on SSD)"
* ASGC - DPM & CASTOR, 4 PB on tape.
* Delegation for srmCopy revisited again - and will be revisited again
again later... (at OGF34), aim to avoid GSI to make it more standard.
* RNS filesystem in Japan, only 10**5 files - US grid also use RNS for
GFFS (Global Federated FileSystem). Also a Universal Grid Interface -
but how do they do storage "universally"
* GARUDA - Indian grid, apprently they have their own SRM, called
GSRM. Can follow up.
* EGI federated cloud aiming for CDMI.
* Discussions whether the cloud is right for everything - maybe not
HPC with MPI due to unpredicatable latency - OTOH, are there similar
aspects for storage?
Chris W : Sandy bridge, performance numbers.
4. Items for EGI forum (and who is going?)
Kashif is going.
5. Planning ahead for GridPP in April.
No suggestions? We'll have to revisit this...

[10:16:01] Duncan Rand which spce tokens?
[10:16:35] Pete Gronbech joined
[10:16:45] Elena Korolkova We do not have such transfers in Sheffield
[10:17:57] Elena Korolkova I suspect tese could be transfers from SCRATCH to LOCALUSER
[10:25:34] Duncan Rand there's a big discrepency in the number of transfers
