Achieving the Dream – One Operating System for Midrange to Enterprise Storage

by Hu Yoshida on Apr 29, 2015

As long as I have been in storage, the dream has been to have a common operating system for midrange and enterprise storage.  This would help to reduce development costs and cycles for vendors, while simplifying management, and providing the right price point without sacrificing functionality for end users. However, since midrange storage is targeted at smaller organizations, with smaller IT budgets, midrange storage systems have always required a different architecture with scaled down functionality and availability. This meant that the operating system for the midrange storage systems had to be different, the functionality was limited and different management tools were required. Hitachi has achieved the dream of a common operating system with the introduction of the Virtual Storage Platform (VSP) models G200, G400, G600, and G800, which run the same operating system as the enterprise-class VSP G1000.

TBR’s Data Center Server and Storage Market Forecast indicates revenue growth in the global data center flash storage market will exceed all other server and storage sub-segments from 2014 to 2018, rising at a 22.9% CAGR to more than $13.5 billion while external data center disk storage revenues will shrink at a 5.3% CAGR to nearly $18.1 billion. For those who believe that only new-style AFAs can succeed in this market, it  would seem to have a dampening effect on the enterprise storage market. In terms of Hitachi Data Systems, we continue to do well with our enterprise storage arrays. Here are some proof points.

Joint Webinar with VMware and HDS – Delivering Simplified Scalable IT with VMware vSphere Virtual Volumes and Hitachi Storage

by Hu Yoshida on Apr 9, 2015

I began 2015 with blog on Hitachi Storage for Virtual Volumes, arguably the most discussed storage technology in recent years. In February of this year Hitachi Data Systems announced the early support for VMware vSphere Virtual Volumes (VVOLs), simplifying customers’ cloud journey and extending the value of Hitachi’s rich infrastructure solutions. VMware vSphere Virtual Volumes is a major technological advancement in the storage ecosystem that can solve several key issues for customers: overprovisioning of storage, inflexibility to perform granular data services, complex provisioning and manual operational changes, lack of agility in responding to business requirements. Hitachi is likely to be the first storage provider to offer NFS integration with VVOLs. Read More »

Transforming the IT Culture: Going Beyond Collaboration to Innovation

by Hu Yoshida on Apr 2, 2015

Today all CIO’s are adjusting to the world of SMAC, Social, Mobile, Analytics and Cloud. IDC refers to this as the third platform, which is changing the focus of IT as mainframes and client/server models have done in the past. Crawford Del Prete, the Chief Research Officer of IDC, has been quoted as saying that CIOs must embrace the 3rd platform.

ENIGMA: Cracking an Encryption Engine

by Hu Yoshida on Mar 30, 2015

On the way home from New York last week I saw the movie “Imitation Game”, which is the story of Alan Turing who led the effort to break the Enigma code with fellow mathematicians at Bletchley Park in the UK during World War II. Although, I rarely watch movies on long plane rides, I was fascinated by this movie, since I had just blogged about data encryption.

My father was born in Hawaii, where Ohana means family. In the Hawaiian culture ohana binds family and friends, to work together and remember one another.   So when I think about HDS and SAP the word OHANA comes to mind.  Why you ask?  Because Hitachi and SAP’s partnership is entering its 21st year and we are currently an SAP global service and global technology partner as well as an OEM partner. Our blade technology and UCP solutions with SAP HANA have earned us a leading position among SAP partners.  At the end of this month we expect to finish the acquisition of oXya, an SAP cloud service provider.  The acquisition will extend our reach into public and hybrid cloud as well as managed services to help customers migrate to the SAP HANA platform with complimentary hardware, software, and services solutions.

SAP HANA Dynamic Tiering and Hitachi UCP

by Hu Yoshida on Mar 30, 2015

I received a question on my last post about the Dynamic Tiering feature announced in SAP HANA SPS 9. The question is how this differs from paging. The simple answer is that Dynamic Tiering is a database management feature while paging is a memory management feature. While SAP HANA is an in-memory database, it is able to tier “warm” data in the database through an extended table schema, which is now part of the HANA database catalog in memory, while the primary data image resides on storage that is outside of memory. For an explanation of SAP Dynamic Tiering you can reference this post which includes this slide. Read More »

Dispelling Myths about IOPs

by Hu Yoshida on Mar 20, 2015

Since the SPC numbers for the G1000 came in at 2 million IOPs and blew away every other all flash array vendor, there have been a number of posts in the blog sphere discussing the relevance of IOPs as a measure of performance. Lets look at some of the myths about IOPs
