Kumar, We are using it onboard, not as add-on card. But I am sure there must be PCI-E to SAS PCI cards based on LSI SAS controllers.
I just googled.... http://cgi.ebay.com/LSI-LSISAS3080X-R-8-Port-3Gb-s-SAS-PCI-X-Host-Bus-Ad apt_W0QQitemZ220243588314QQihZ012QQcategoryZ90715QQcmdZViewItem?refid=st ore - Siva -----Original Message----- From: Kumar Gala [mailto:[EMAIL PROTECTED] Sent: Thursday, June 26, 2008 6:37 AM To: Siva Prasad Cc: linuxppc-embedded@ozlabs.org Subject: Re: Migrating from 2.6.11 to 2.6.23 breaks pci-e with LSI 1068 SAS chip Is the LSI chipset something you guys have on an add-on card (something we can put into a reference board) or is hard wired into your boards? If its an add on card a pointer to one would be appreciated. - k On Jun 25, 2008, at 5:20 PM, Siva Prasad wrote: > I am also having problems with PCI-E device LSI 1064E on 2.6.24-rc6 > kernel.
