N B drives with 680 x 200GB 9940B tapes => 136TB (free) Our silos will be upgraded to 5500 slots (2000 LTO form factor B form factor) Upgrade with other 4x9940B drives and 2500 x 200GB tapes (500TB) not before 2nd half of 2005

8 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
