INFINIDAT is tweaking its Infinibox array design to increase its capacity. The present 3U drive trays and 2U controller enclosures will each become 1U trays, enabling an increase from 480 drives to 720 in a rack – a 67 per cent increase. These drive trays hold 60 vertically mounted disk drives. At INFINIDAT’s Herzliya office, press visitors saw an Infinibox array in the data centre with three 1U server enclosures, releasing 3U from the current 3 x 3U controller (Dell 370 server) enclosures. Below this were 1U drive trays holding rows of flat-mounted Seagate 3.5in Constellation ES drives. We calculated there were 20 drives per tray and space for 36 trays in the rack, making up the 720-drive total we were quoted.
