The internal builds of Solaris 10 8/11 (update 10) have had another refresh of the ZFS code. It is now be synced with snv_153 which is a even later build than Solaris 11 Express 2010.11 is based on. Also related to storage this update will support the LSI SAS 2308 HBA and the LSI SSS 6200 Solid State Storage.
I've been using Unix, mainly Solaris for over 15 years. While Solaris was open I tried to be part of the community with this blog and by filing bugs and debugging.
During the days I work with standardization and implementation of the Unix platform at a large company. This involves design and implementation of Solaris and everything around it including security, performance, storage, virtualization and development.
I also work as a consultant part time and can be contacted at henrik (at) gigamega.se.
