IT Does Matter – And the World is not Flat

by Hu Yoshida on Jun 19, 2014

Back in 2003, as the IT industry was recovering from the excesses of the dot com boom/bust, the Harvard Business Review’s Editor-At-Large, Nicolas Carr published a paper titled IT doesn’t Matter, in which he claimed that “As information technology’s power and ubiquity has grown, its strategic importance has diminished.”

X86 WITH LPARS – A REALITY FOR SAP BUSINESS SUITE CUSTOMERS

by Hu Yoshida on Jun 12, 2014

“A logical partition, commonly called an LPAR, is a subset of computer’s hardware resources, virtualized as a separate computer. In effect, a physical machine can be partitioned into multiple logical partitions, each hosting a separate operating system.” from Wikipedia

BUSINESS DEFINED IT FOR SAP HANA

by Hu Yoshida on Jun 3, 2014

SAP HANA provides real time business insights that accelerate business success. It depends on a responsive IT architecture that can quickly react to changing business demands with enterprise availability and performance. Hitachi Data Systems partners with SAP to provide that architecture through Business-Defined IT with the certification of the new VSP G1000 enterprise storage system and the HUS VM midrange storage system under SAP’s Tailored Data Center Integration (TDI) program. What does this mean for SAP HANA customers?

BUSINESS DEFINED IT – ALIGN BUSINESS PROCESSES WITH YOUR DATA CENTER ECOSYSTEM

by Hu Yoshida on Jun 2, 2014

VMware users can align IT with business processes through their VMware vCenter Operations Manager (vCOPs), coupled with Hitachi Unified Compute platform for VMware vSphere and its Unified Compute Platform Director software.  This converged-infrastructure management platform centralizes and automates the management of all of the hardware elements in VMware vSphere through a single pane of glass. It provides deep insights into the health, risk, and efficiency for each of the converged elements within vCenter Operations Manager (vCOPs) and integrates the management of physical and virtual layers to significantly reduce mean time to resolution & operational costs – across a single or multiple data centers.

Where are the performance specs for VSP G1000?

by Hu Yoshida on May 23, 2014

In my blog post that supported the announcement of the VSP G1000 with SVOS, Storage Virtualization Operating System,  I described VSP G1000 as a unified storage platform that can provide approximately 4 million random reads for 8KB blocks or more than 1.2 million NFS operations for file.

TAKING VMWARE TO THE NEXT LEVEL IN PERFORMANCE, AGILITY, AND AVAILABILITY

by Hu Yoshida on May 19, 2014

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. While VMware has tools like vMotion and Storage vMotion to rebalance the workload and SRM (Site Recovery Manager) to recover from site failures, the movement of data between storage systems and the reconnection of servers and application to servers can be very disruptive and unpredictable in large VMware configurations. In many cases, this is because the storage technologies have not advanced at the same pace as server technologies, or have different implementation types and scalability and processing requirements.

ELIMINATE THE APPLIANCE TAX FOR GLOBAL ACTIVE DEVICES

by Hu Yoshida on May 13, 2014

Hitachi Data Systems announced a new global active device capability within the new Storage Virtualization Operating System (SVOS) and the new Virtual Storage Platform G1000 (VSP G1000) storage system.  This enables a virtual device to span two VSP G1000 storage systems that are separated by up to 100 KM apart for load balancing and active/active availability. This enables an application from either site A or site B to access a shared device through either VSP G1000, and continue operations if one of them should happen to become unavailable. A cluster application like Oracle RAC could access the device through either site as well as through either G1000 for greater availability.

Will your ECB disk storage be supporting you in seven years?

by Hu Yoshida on May 2, 2014

A lot can happen in 7 years. By 2021, we will all be 7 years older. The explosion of technology trends like mobility, cloud, social, and the Internet of things will drive orders of magnitude more data and drive tremendous changes in our business and in our lives. IDC in their predictions for 2014 predicted that the average home would have 20 sensors by 2020 that will generate 200TB of data per year, per household. The amount of data that we will need to manage may be orders of magnitude more than we have today in 2014.

What is the next step in Storage Virtualization?

by Hu Yoshida on Apr 10, 2014

In 2004 Hitachi Data Systems introduced the Universal Storage Platform, USP, which was the first storage array that could attach and virtualize third party Fibre Channel storage arrays. Instead of following other vendors by doing virtualization through an appliance that added complexity and another layer of management in the Storage Area Network, Hitachi chose to do virtualization through the storage controller.  By virtualizing external storage through the USP controller, the virtualized arrays could inherit the latest capabilities of the USP and be managed through the USP management interface. Limited function, dual controller storage arrays could now be virtualized and inherit all the functions of an enterprise array, including a global front-end cache with an extended number of host ports, and full synchronous and asynchronous replication.
