Edison analysts put the management software of an HP EVA system through a series of typical day-to-day storage management tasks. The same tasks were also evaluated on similar systems from NetApp and EMC. This study demonstrates how the superior user interface and virtualization offered by the HP EVA storage system can provide organizations with the benefits of higher administrative efficiency combined with the potential ability to utilize less expensive human resources.

The powerful tape technology can address data security with tape encryption as well as long term data protection.
Discover what disk and tape really cost -- and which solution provides lower total cost of ownership and optimizes energy use for your organization
The Clipper Group explores the truth behind the myths of tape, digging into the misconceptions in the disk vs. tape debate.
Over two thirds of disk-only users look to add tape back into storage infrastructure according to recent survey.
IBM is developing a type of memory that it says could one day be faster and more reliable than today's hard drives and flash memory.
Called "racetrack," it is a solid-state memory that aims to combine the best attributes of flash, like having no moving parts, and the low cost of hard drives for an inexpensive form of nonvolatile memory that will be stable and durable, said Stuart Parkin, an IBM Fellow.
Racetrack memory stores information in thousands of atoms in magnetic nanowires. Without the atoms moving, an electrical charge causes data to move swiftly along a U-shaped pipe that allows data to be read and written in less than a nanosecond, Parkin said. A nanosecond is a billionth of a second and commonly used to measure access time to RAM.
The memory reads 16 bits of data through one transistor, so it reads and writes information 100,000 times faster than flash memory, Parkin said.
"In flash memory and hard drives, one transistor can access 1 bit, or with flash, maybe 2 or possibly even 4 bits, that's it. We are going to use ... a transistor to access many bits of information."
Racetrack is still in its early days. The concept was proposed four or five years ago, Parkin said, and IBM hopes to be able to provide terabytes worth of storage from such devices in a few years.
"It will take two to four years to build a prototype in which we build these reading-and-writing elements on a nanoscopic scale. In four years we can perhaps demonstrate it works and then manufacture it," Parkin said.
Racetrack memory has no moving parts, it is "virtually unbreakable" and will never wear out, unlike flash drives, which could wear out after 10,000 read-and-write cycles, Parkin said. He likened the U-shaped design of horizontal pipes to a racetrack.
The memory keeps atoms constant, making it more durable than hard drives or flash. "Whenever you start to move atoms you have problems and devices wear out from fatigue after a time," Parkin said.
Racetrack memory's storage capacity is similar to flash's and may soon exceed hard-drive capacities, Parkin said.
