Will the HP StorageWorks Multi-Protocol Router Blade work with the existing Fabric OS versions in my current fabrics?
Yes, the HP MP Router Blade is fully compatible with installed based of HP StorageWorks B-series switches and directors. Most customers will not need to upgrade the Fabric OS version on the installed switches. Customers who have not upgraded Fabric OS on their installed switches for more than two years might need to migrate to a later version.
