EMC’s Iomega portfolio is no stranger to the higher end of the small business storage market, but its latest addition, the StorCenter PX series of desktop and rackmount NAS devices, raises the bar. Acquired by EMC in 2008, Iomega has historically focused on the 25 to 50 user range, but the PX series addresses the 100 to 250 user range, while still clearly differentiating itself from its parent’s entry-level VNX family.
