About

GARR is funding a mirror archive. The overall capacity is now about 2 x 120 TB total (raw capacity excluding RAID), distributed in two locations of its network. The architecture includes two different SANs for the two sites hosting the mirror servers. In each site is installed, since December 2011, an HP P2000 SAS storage disk array.
