Yes it''s PCI-X. I assume your asking because they can not (or no longer) be obtained? Neil.
You can find these at: http://www.umem.com/Umem_NVRAM_Cards.html And the one Neil was using in particular: http://www.umem.com/MM-5425CN.html - Eric On Wed, Jul 18, 2007 at 01:54:23PM -0600, Neil Perrin wrote:> > > Albert Chin wrote: > > On Wed, Jul 18, 2007 at 01:29:51PM -0600, Neil Perrin wrote: > >> I wrote up a blog on the separate intent log called "slog blog" > >> which describes the interface; some performance results; and > >> general status: > >> > >> http://blogs.sun.com/perrin/entry/slog_blog_or_blogging_on > > > > So, how did you get a "pci Micro Memory pci1332,5425 card" :) I > > presume this is the PCI-X version. > > I wasn''t involved in the aquisition but was just sent one internally > for testing.

Apparently not ;-) I hope Sun will sell something like this, perhaps even by default in x4500 and similar servers and also as a separate card. -- Best regards, Robert mailto:rmilkowski at task.gda.pl http://milek.blogspot.com
Hi, what is necessary to get it working from the solaris side. Is a driver on board or is there no special one needed? I just got a packed MM-5425CN with 256M. However i am lacking a pci-x 64bit connector and not sure if it is worth the whole effort for my personal purposes. Any comment are very appreciated -ah This message posted from opensolaris.org

So your MM-5425CN doesn''t fit into a PCI slot?> Any comment are very appreciatedHow did you obtain your card? -- albert chin (china at thewrittenword.com)
Adolf, Yes, there was a separate driver, that I believe came from Micro Memories. I installit from a package umem_Sol_Drv_Cust_i386_v01_10.pkg. I just use pkgadd on it and it just worked. Sorry, I don''t know if it''s publicly available or will even work for your device. I gave details of that device for completeness. I was hoping it would be representative of any NVRAM. I wasn''t intending to endorse its use, although it does seem fast. Hardware availability and access to drivers is indeed an issue. 256M is not a lot of NVRAM - the devive I tested had 1GB. If you have a lot of synchronous transactions then you could exceed the 256MB and overflow into the slower main pool. Neil.
