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.

SAP HANA GOES OHANA

by Hu Yoshida on Mar 30, 2015

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.

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 »
