Perhaps you have seen this Indycar with the big Hitachi logo in the news. Hitachi America, Ltd., and Hitachi Automotive are sponsoring the Penske Indycar races in 2012, with Ryan Briscoe as the driver of the Hitachi car. One of the races took place this past weekend in Sonoma, California, where Ryan won first place [...]

Tom Coughlin of Coughlin Associates and Jim Handy of Objective Analysis, two market and technology analysts who blog for Forbes.com, have initiated a survey of storage end users.  The object is to determine the Input/Output Operations Per Second (IOPS) for several popular enterprise applications.  This survey is on-going and the results are expected this fall.

Today, HDS is making an announcement about its strategy for incorporating flash technology across the IT stack. This includes a flash acceleration feature available today for Hitachi Virtual Storage Platform (VSP) that enables it to achieve more than 1,000,000+ random read IOPS.

In my previous post I described the unique Hybrid NAS (network attached storage) controller architecture and the object-based file system in the file module of Hitachi Unified Storage (HUS) and in our Hitachi NAS Platform products. The results of this architecture combined with the automated tiering and high performance of our storage systems, makes this [...]

As more and more data is being created, knowledge about storage technology is becoming more important to a wider audience. In my interactions with customers, I am meeting more server, networking, and applications people who are assuming more responsibility for storage and are looking for a structured way to understand storage technologies so that they [...]

In addition to redefining the storage controller with a load balancing active/active architecture, redefining NAS controller with a hybrid CPU/FPGA file module for increased performance and scalability, and redefining an object based file system for auto tiering, cloning, and mirroring across multiple volumes, Hitachi Unified Storage(HUS) also redefines unified management.

In this blog series on Redefining Unified Storage, I covered Hitachi Unified Storage (HUS) Dynamic virtual controller, which simplifies the management of LUN assignments and provides enterprise class load balancing. I followed that with the hybrid architecture of HUS file modules, which combine multicore CPUs with FPGAs to increase the throughput performance and scalability of [...]
