Minutes of storage phone conference 24 May 2006 Present: Edinburgh: Greig Lancaster: Matt Durham: Mark Tier 1: Derek RAL Storage: Owen, Jiri, Jens (chair+mins) Apologies: Glasgow: Graeme 0. Review of actions (see below) 1. dCache deployment status issues See also action #106 below. YAIM changes need to go in today, or else they don't go in. Greig will do the prerelease testing before the end of the day (ACTION). May be useful to know about the Xen stuff. Jiri can provide documentation. There appears to be no documentation in the Wiki either. (ACTION) 2. Site hardware recommendations (% storage) Jens had sent a summary to the list (only about a half hour before the meeting) which was then discussed, although no one had had time to read it. Apart from the concerns raised in the document, we are also concerned about the quite ambitious targets for Tier2 storage - the ratios are one thing, and the absolute values we're trying to hit another: e.g., Atlas UK targets for Tier 2s: 2007 2008 2009 2010 2011 2012 161 875 1591 2582 3296 4094 That's in TBs. UK total is 2007 2008 2009 2010 2011 2012 310 1409 2580 4087 5222 6472 In any case, the document becomes a response which we will send back to the UB for their next meeting in June, and can also send to the PMB. ACTION ALL: feedback on these issues to Jens. 3. VO pool allocations discussion Also in the document. 4. AOB Owen mentioned that he will be at DESY for two weeks, and will help them improve their release procedures and infrastructure. Question whether we should escalate the poor release build service that we sometimes get from LCG - support from Oliver Keeble and Louis Poncet is _excellent_ but when they're not around, it's poor. Greig will run the meeting next week - or let us know if he can't. ------------------------------------------------------------------------ ACTIONS 41 10/08/2005 Agree licence with DESY Jens Open No news. 53 12/10/2005 Find reasoanable % for SE uptime for SC4 Jeremy Open No news. 54 02/11/2005 Report on performance/scalability with pools on WNs Paul Open No news. 86 08/02/2006 Extend monitoring to do sites per VO and VOs per site Greig Open No news. 103 19/04/2006 Send dCache shopping list items to Owen/Jens, then prioritise ALL Open Ongoing.
