) ▁is ▁the ▁interface ▁architecture ▁used ▁to ▁transmit ▁data ▁from ▁the ▁storage ▁controllers ▁to ▁the ▁disk ▁drives ▁in ▁the ▁Ada pt able ▁Mod ular ▁Storage ▁ 2 0 0 0 ▁family . ▁The ▁S AS ▁interface ▁is ▁a ▁full ▁du plex , ▁point - to - point ▁architecture ▁with ▁up ▁to ▁ 9 6 0 0 MB / sec ▁of ▁total ▁system ▁band width ▁and ▁up ▁to ▁ 3 2 ▁links ▁available ▁for ▁concurrent ▁I / O ▁activity . ▁This ▁design ▁elimin ates ▁FC ▁Loop ▁arbitr ation ▁resulting ▁in ▁better ▁performance ▁and ▁enables ▁improved ▁end ▁user ▁troubles ho oting ▁by ▁detect ing ▁and ▁displaying ▁failed ▁drives ▁automatically . ▁ ▁Add itional ▁Fe atures ▁ ▁The ▁A MS ▁ 2 0 0 0 ▁family ▁of ▁storage ▁systems ▁includes ▁Hit achi ▁Dynamic ▁Pro vision ing ▁software , ▁which ▁provides ▁propriet ary ▁automatic ▁optimized ▁wide ▁strip ing ▁of ▁data ▁across ▁all ▁available ▁dis ks . ▁It ▁enables ▁storage ▁to ▁be ▁provision ed ▁when ▁the ▁application ▁actually ▁requires ▁it , ▁rather ▁than ▁at ▁allocation ▁time . ▁ ▁The ▁storage ▁capacity ▁of ▁the ▁Hit achi ▁Ada pt able ▁Mod ular ▁Storage ▁ 2 0 0 0 ▁family ▁scales ▁to ▁ 1 , 4 1 7 TB . ▁With ▁the ▁band width ▁provided ▁by ▁the ▁S AS ▁architecture , ▁performance ▁continues ▁to ▁increase ▁as ▁more ▁drives ▁are ▁added ▁to ▁the ▁system . ▁ ▁All ▁models ▁of ▁the ▁Hit achi ▁Ada pt able ▁Mod ular ▁Storage ▁ 2 0 0 0 ▁family ▁support ▁host ▁path ▁fail over , ▁fully ▁redundant
