Enterprises will be able to fit 12 flash modules on each tray in the HUS VM, with a full eight-tray system holding more than 150TB of capacity. That will double by the end of this year, as the company plans to come out with a 3.2TB module.
The flash modules are available now for US$28,427 each, and an all-flash HUS VM with 8TB of flash capacity costs about $300,000, including the Base Operating System and three years of maintenance.
