Yeah, no driver issue. BTW, any new storage-controller-related drivers introduced in snv151a? LSI seems the only one who works very closely with Oracle/Sun. Thanks.

Sure. Gotcha! ^:^> -----Original Message----- > From: James C.

I tested the Fusion IO MLC based PCI-e cards on OpenSolaris and found the performance to be amazing. Hopefully Fusion IO will release supported drivers for Solaris 11 Express and onwards. The Fusion IO MLC card was giving me around 500MB/s write performance with O_SYNC. -Moazam On Wed, Nov 17, 2010 at 7:49 PM, Fred Liu <Fred_Liu at issi.com> wrote:> http://www.lsi.com/channel/about_channel/whatsnew/warpdrive_slp300/index.html > > > > Good stuff for ZFS. > > > > Fred > > _______________________________________________ > zfs-discuss mailing list > zfs-discuss at opensolaris.org > http://mail.opensolaris.org/mailman/listinfo/zfs-discuss > >

The Fusion IO > MLC card was giving me around 500MB/s write performance with O_SYNC.I think most SSDs will give one excellent performance, but a lot of people on this list also worry about data consistency as well. Many devices lie about doing cache flushes when they''re told to, and this is a big issue when it comes to ZFS'' on-disk consistency guarantees. Also, since most SSDs don''t have batteries or supercaps, when the power goes away so does the DRAM cache, and so many in-flight operations could be lost. Fusion released a new model that "Guarantees data integrity in the event of power loss" with "No failure-prone batteries or super-capacitors needed to protect in-flight data": http://tinyurl.com/327ntp4 http://www.fusionio.com/press/Fusion-io-Delivers-Next-Generation-ioMemory-Module/ What that means I don''t know.
The FusionIO MLC PCI-e device I tested is capacitor backed (just not super-cap). The OCZ Deneva SATA SSD I tested is super-cap backed. -Moazam On Nov 18, 2010 6:17am, David Magda <dmagda at ee.ryerson.ca> wrote:> On Thu, November 18, 2010 05:11, Moazam Raja wrote:> > I tested the Fusion IO MLC based PCI-e cards on OpenSolaris and found> > the performance to be amazing.
