The rack-sized Exablox OneBlox is an eight-bay NAS array employing CIFS and SMB file systems and a maximum capacity of 48 TB. The 3.5-inch hot-swap bays in the company's flagship array accept any combination of SAS or SATA spinning or solid-state drives without the use of drive trays or caddies. When more storage is needed, a solution provider can simply slide in any commodity drive that's handy or quickly provision one to the site for the customer to insert. Its four Gigabit Ethernet ports can be aggregated or configured for redundancy. Front-panel LEDs report the status of each drive and the system as a whole.
