Is it possible to upgrade from a SAS 6/ir integrated card to a PERC 6/i card without losing anything in a Windows Server 2003 R2 x64 environment?
Driver version on the SAS 6/ir is 220.127.116.11
Or is there anyway to force wite cache to be on? The whole server is on a battery back-up which I think would suffice.

I think the answer to your specific situation and question is "no". While the PERC 6 does support migration from SAS 6 controllers, apparently it will not successfully boot if migrating a Windows system, so migrating a data volume/array is the only way it makes sense on a Windows system. I don't know exactly what the problem would be - if it is something that can be repaired or if it simply will not work.
Compatibility With Virtual Disks Created on SAS 6/iR Controllers
Virtual disks created on the SAS 6/iR family of controllers can be migrated to PERC 6 and CERC 6/i. However, only virtual disks with boot volumes of the following Linux operating systems successfully boot after migration:
Red Hat® Enterprise Linux® 4
Red Hat Enterprise Linux 5
SUSE® Linux Enterprise Server 10 (64-bit)
NOTE: The migration of virtual disks with Microsoft® Windows® operating systems is not supported.
CAUTION: Before migrating virtual disks, back up your data and ensure the firmware of both controllers is the latest revision. Also ensure you use the SAS 6 firmware version 00.25.47.00.06.22.03.00 or newer.

One thing that might work is the following (dependent on your server model and the available PCIe slots):
- add the PERC6i to the server (leaving the SAS6iR card in the system and the drives connected to it)
- boot into Windows and let Windows install the appropriate driver
- shut down
In theory you can now move the drives over to the PERC6i adapter and boot Windows as Windows will now have the appropriate PERC drivers already installed.

Thanks for the recommendation. After some more thorough searching through forums I found a Dell SAS Raid Manager tool that allowed me to Enable Disk Cache and that so far has made a huge difference. Not sure why whoever bought this server in the first place didn't go with the PERC 6 but atleast this is a decent fix for now.
I feel your pain and I hope that you can find a fix for yours.
I found a linux version of the SSM which can be found here http://support.euro.dell.com/support/downloads/format.aspx?c=uk&l=en&s=gen&deviceid=9745&libid=36&releaseid=R165253&vercnt=1&formatcnt=0&SystemID=LATITUDE%20PRECISION%20390&servicetag=&os=LIN4&osl=en&catid=-1&dateid=-1&typeid=-1&formatid=-1&impid=-1&checkFormat=true (not sure why but I could only find these files on the euro support site)
the windows is here: http://support.euro.dell.com/support/downloads/download.aspx?c=uk&l=en&s=gen&releaseid=R163453&SystemID=LATITUDE%20PRECISION%20390&servicetag=&os=WW1&osl=en&deviceid=9745&devlib=0&typecnt=0&vercnt=3&catid=&impid=&formatcnt=0&libid=36&typeid=-1&dateid=-1&formatid=-1&fileid=219513
There are also multiple versions of it listed here: http://ftp.dell.com/sysman/ (look for SSM)
I was also looking into being able to do it via the OpenManage from Dell but since this worked I didn't need to go that far.
Thanks a million plus if this works for me. I am going to Vmotion my VM's off and try it. So... Do you have to do this after reboots? Or you set it once and it works from then on as long as the controller doesn't get replaced. if the latter, I guess I could just boot a real linux version from USB or CDrom and do it.
I haven't had a chance to reboot and check because our ts server is used 24/7 but I've planned for a reboot at 3 am tomorrow morning and will post whether it is still on but my guess is that it would only be reset if the controller or disks were replaced.
Glad I could help.
So I actually installed this on my ESX Vsphere host. It installed, it stated it was able to start the services.
Now what? How do I actually turn on the cache? Sample command line please? or is there some sort of use interface with the SSM?
