According to Herzog, the all-flash array offers 80% lower cost per transaction because it would otherwise take a vast number of high-performance hard drives to achieve the same performance.

EMC's traditional VNX arrays - models VNX 5500 and VNX7500 - now come in a high bandwidth option.

A dual controller VNX7500 array in a single rack configuration now offers up to 14GB/sec throughput. On the VNX5500, the high bandwidth option delivers up to 6.5 GB/sec performance.

Both models are also available with 3TB SAS drives, which offer up to 1.6 petabytes of capacity in a rack. There is also a 60-slot drive tray for VNX line that comes in a 4U (7-in high) configuration.

EMC user Patrick Williams, a systems specialist at North Carolina State University, said the ability to "squeeze 1.6PB of capacity into just one floor tile" in a data center is impressive.
