About service packs for SQL Server
Service packs are cumulative. Each new service pack contains all the fixes that are in previous service packs, together with any new fixes. Our recommendation is to apply the latest service pack and the latest cumulative update for that service pack. You do not have to install a previous service pack before you install the latest service pack. Use Table 1 in the following article for finding more information about the latest service pack and latest cumulative update.

Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.
More information
Nodes are created to correspond with the physical NUMA memory nodes. These might differ from the CPU nodes in sys.dm_os_nodes.

The DAC node is reserved for the Dedicated Administrative Connection.

The Pages_kb value specifies how much committed memory in kilobytes (KB) is allocated from this NUMA node by the Memory Manager Page Allocator. This value cannot be null.
