by Hu Yoshida on Feb 3, 2014


One of my top 10 IT trends for 2014 called for the explosion of enterprise flash. Now you are seeing more and more vendors introducing flash arrays that claim enterprise performance and durability based on something called eMLC, where the “e” stands for enterprise and MLC stand for Multi Level Cell or 2 bits per cell.

SAP AG, Hitachi, and Hitachi Data System extends relationship with Global OEM Agreement for SAP HANA

by Hu Yoshida on Jan 23, 2014

SAP AG evaluated the Hitachi Converged solution for SAP HANA performance and found it to be as much as 5 times the performance of other competitive solutions. As a result of this evaluation and the success that Hitachi Data Systems has had with selling and installing Hitachi Unified Compute Platform converged solutions with SAP HANA, SAP AG has expanded its 20 year worldwide strategic relationship with Hitachi Ltd and Hitachi Data Systems by signing a global original equipment manufacturer (global OEM) agreement to include SAP HANA for BW delivered by HDS. Customers should achieve maximum value from a unified compute platform that is integrated with SAP HANA from a single source that has leading blade server technology, storage virtualization, file and content services, and enterprise class disaster tolerance. Hitachi and SAP will also co-innovate to deliver and provide further integration solutions for cloud computing, the SAP Real Time Data Platform, and high performance enterprise computing.

Storage Magazine Midrange NAS Quality Award – And the Winner is….. Hitachi!

by Hu Yoshida on Jan 21, 2014

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 Storage Magazine and SearchStorage.com readers where Hitachi recently won the Quality Award for midrange NAS for the second year in a row.

Top Ten IT Trends for 2014- Trend 9

by Hu Yoshida on Dec 17, 2013

Trend 9: Encryption of data at rest becomes table stakes

Recently, I had a discussion with a customer about capacity-on-demand who said he had a rolling lease program where he continually refreshed his storage every three years. When I asked him what he did to ensure that his data was shredded when he rolled his storage off lease, he gave me a blank stare. Either he was not aware of what was being done or he trusted his lease provider to see that none of his company’s data was left on the storage at the end of the lease. The same response came from a customer who was using cloud storage to supplement his seasonal requirements. There should be some record to show that the data was shredded to satisfy the compliance people.

The initial excitement over flash performance is becoming tempered by concerns over the “write cliff,” storage density, and durability that are the result of using commodity SSDs in enterprise storage systems.

Trend 7: Reduction of Backup through Archive, Copies, and Snaps

One of the trends I identified last year was the explosion of data replication, which was cited in an IDC study that claimed the creation and management of multiple copies exceeded the cost of primary storage in many environments. IDC has posted a running time clock which tracks the word wide cost of data copies since January 2013. As of the date I wrote this post, it stood at over $44,128,957, 900. Read More »

Top Ten IT Trends for 2014- Trend 6

by Hu Yoshida on Dec 5, 2013

Trend 6: Object Storage Casts Light on Dark Data

2014 will see more awareness of the existence of dark data and the potential that it has for business value.  Gartner defines dark data as the information assets organizations collect, process and store during regular business activities, but generally fail to use for other purposes (for example, analytics, business relationships and direct monetizing). Much of the focus of Big Data is getting access to dark data.
