RE: Managing Dell Powervault 220s from Poweredge 2950
There is. You can do some looking around for the Dell Adaptec U320. (I assume the SC11Xe is U320) I'm not sure if we sell it on our site, but you can probably find them around.
If it's not an Ultra 320, search for the Dell Adaptec 39160.
Both of these options will work with OMSA.
Let us know how it goes!
Have a good day!
