News from Alberto et al. Fibers document separated from the rest of the computing resources Documents finalized (end of August) Power requirements: 100 kW total Racks Racks on Jura side: 800 mm depth (standard CERN racks) Racks on Saleve side: 1000 mm depth Dimensions of racks’ base plate is needed (for the supports)

Power Computing nodes: 9kW/rack 2 to 5 racks Storage nodes: 5kW/rack 3 racks Support: 1/2 rack, 4kW DCS,DSS 4 kW 2 racks Network: 4kW GTK: 3 kW/rack 3 racks + cooling doors: 1 kW/door, 10kW Total: 68 kW (include 50% safety margin: 95 kW)

Computing nodes How much total computing power for 2012? Specify AMD or INTEL? How many processors? How many cores? Intel Westmere architecture (32 nm): Xeon 5600, 6cores X series, up to 3.33 GHz E series, up to 2.66 GHz L series, low-consumption, up to 2.26 GHz CERN Openlab tested system: GHz, 16 cores 2×6 GB RAM, 450 W power load (full load), 238 HEPSPEC06 (24 processes)=20/core In one 9 kW rack, 20 systems, 4760 HEPSPEC06, approximately 1250 kSi2k How much RAM? How much local disk space? How many 10 Gb and 1 Gb ports/machine? (How many switches?)

Storage nodes How much disk for 2012? Availability of CMS hardware 12 disk arrays with 12 disks each and redundant fiber channel interface: 120 disks WD raptor 300GB (bought at the beginning of the year) 24 disks 1TB 2x 32 port fiberchannel switch 10 DELL servers 2950 with redundant fiber channel cards. Questions: More technical details asked to our CMS colleagues Cost? Maintenance?

Procurement Racks and cooling doors Difficult/not possible to join CERN-IT tender Network apparata Handled by CERN-IT, installation, management, maintenance included Computing & storage nodes How to handle the purchase/acquisition? (CERN, Mainz?...) Time plan for purchase and delivery?

Man power Who and when is going to do/follow/check: Installation Commissioning Operations More: What about UPS system purchase/installation? Remote monitoring of cooling doors (discussion going on with DCS central team
