This page is devoted to keep track of the activity about comparative tests over all SRMv2 Instances. The aim of this activity is to have a preliminary overview of the behavior of all main Storage technologies available on WLCG and equipped with SRM v2 under critical conditions (CASTOR, d-Cache,StoRM and DPM). The persons actively involved on this activity are: Luca Dell'Agnello (CNAF site manager, CASTOR support) Vincenzo Vagnoni (CASTOR and StoRM ^? support), Angelo Carbone (CNAF site manager, CASTOR support) Luca Magnoni and Riccardo Zappi (StoRM ^? developers), Giacinto Donvito and Vincenzo Spinoso (Bari site managers, dCache support), Elisa Lanciotti and Roberto Santinelli(main testers from LHCb at CERN)

Initially the test performed entirely consist on the Elisa's TestSuite ^? used previously to study StoRM ^? storag. The plan for this activity is then to extend the scope of the stress tests for more deepy studies on the perfomaces of various storages solutions, their ooptimizations and their readiness for substain a HEP production like use case. The current infrastructure is summarized on the following table:
