NTTPC is a strategic technology company within the large NTT group in Japan. They have been evaluating and contributing to the open source distributed file system GlusterFS since 2007, developing tools, documentation, and introducing it into their products and services. After diving deeply into GlusterFS, they see potential to expand its capabilities to integrate cloud and on-premise storage as well as block storage interfaces. They also recognize a need for features like thin provisioning and want to focus on growing the GlusterFS community in Japan.

15. Some kind of!
ULTIMATE GlusterFS!
which I devise

16. Some kind of ULTIMATE GlusterFS which I devise
GlusterFS’ front-end is enough cool. But rather back-end
can be expanded. Simply mix cloud and on premise
storages to provide services in a good balance.

17. Some kind of ULTIMATE GlusterFS which I devise
File storage and object storage are both achieved.
To become truly unified storage,
block storage interface should be implemented.

19. Focus on the community
! High interests in Japan, not only English-
speaking countries
 About 30 cutting-edge engineers had a discussion
in GlusterFS round-table talk.
 Engaging in a heated Qs and As in front of 100
people in Cloud Storage Conference.
 Regardless of professions or places of employment,
about 6 of 45 already had experiences with
GlusterFS in InfiniBand DAY 05.
 A few companies ask us consult as to GlusterFS.
! But Japanese are ...
 Not good at English (especially speaking and listening)
 Shy
 GMT+9 (a long time distance on the earth far, far away ....)
Japanese localized community is important.
Let’s get it started! 19
