CMS T2 requirements
Basic requirements to CMS VO T2 sites for Physics group hosting: a) info on contact persons responsible for site operation b) site visibility (BDII) c) availability of CMSSW actual version d) regular file transfer test “OK” e) Certified links with CMS T1: 2 up and 4 down f) CMS job robot test “OK” g) disk space ~ 150-200 TB for: - central space (~30 TB) - analysis space (~60-90 TB) - MC space (~20 TB) - local space (~30-60 TB)
- local CMS users space (~1 TB per user) h) CPU resources ~ 3KSI2K per 1 TB disk space, 2GB memory per job
11
T2 readiness requirements
• Site visibility and CMS VO support
• Availability of disk and CPU resources
• Daily SAM availability > 80%
• Daily JR-MM efficiency > 80%
• Commissioned links TO Tier-1 sites ≥ 2
• Commissioned links FROM Tier-1 sites ≥ 4

Request for RDMS CMS T2s upgrade
CMS request to upgrade by Jan. 2010:
Total disk space – up to 1300TBTotal CPU - up 4500kSI2K (~1800 job slots)
First priority tasks:
- Complete T1<->T2 link certification for INR, IHEP, PNPI- Improve stability of operation (“availability” & “readiness”)- Full test of MC prod and analysis jobs running in parallel- Increase disk space at each of T2 up to 150 TB- Increase number of CMS job slots at each of T2 up to 200

Summary
ITEP, JINR, SINP and UA_KIPT- in a stable state RRC_KI – all sw required is installed, the links are certified but not in a
stable state INR – not all the links required are certified – to be accomplished in a
month or earlier PNPI – now installed 1 Gbs external channel; certification of link is in
process IHEP – now installed 1 Gbs external channel; certification of link is in
process ITEP, JINR and SINP support group space for MUON, JetMET/HCAL, HI and
Exotica – thus the main efforts were applied to certify links to/from these institutes
