I am not sure, MPXIO is a feature in the transport layer (fc); anyway this is something you need to check with the storage group. > If so, is it still supported if we use HBA from OLogic directly, yet > using HBA driver from Sun? You can use whatever hardware you want, as long as it is some Sun supported hardware. LDoms just need disks/LUNs to be accessible. > If we choose to go for H/W RAID 1, with max # of disks, i.e. 8, > installed, how many LDoms can we create? If you want to export an entire disk to each domain then obviously you can create 8 domains > Also according to the URL, bug 6514091 has been fixed in S10U5. > Does that mean we will be able to use VxVM Volume as OS device for LDoms > with U5? Yes 6414091 is fixed in U5, so you can export VxVM volumes as virtual disks to guest domains. alex. > Alexandre Chartre wrote: >> >>> >>> Thank you for answering and thanks for your support.
