As servers increase their number of cores and memory performance, VMware is able to scale up additional virtual machines and drive more applications almost indefinitely. Unfortunately, each virtual machine adds additional random I/O workload, and the storage systems become a bottleneck.

Her latest report on January 31 of this year reconfirms that 65% of external storage systems capacity is used to store [...]

In past years, when customers were asked to name the leader in midrange NAS; Hitachi was probably not on the top of the list. Hitachi has long earned a reputation for enterprise scalability, availability, and performance, but never made an impression in the midrange. Well that perception has changed according to a survey of qualified [...]

By now the major analyst firms have published their trends for 2014, and there is pretty common consensus over the macro trends that will be drivers for opportunities and threats in the years to come.
