Punti di discussione Uso CPU, al momento, non critico (anzi…) Occorre uniformare accesso per ottimizzare uso Piu’ critico lo spazio disco ~ 32 TB disponibili (+ ~ 26 TB con estensione 20% ultima gara) Gia’ in arrivo richieste… CASTOR alternativa valida per compensare Buffer temporanei e/o distribuiti su dischi WNs Importante avere previsione di uso “vera” Pianificazione a breve/medio termine con esperimenti
