Extended Socket
Extended Socket is the function which enables up to 20 Gbps high-speed communication among Extended
Partitions on the same physical Partition.
Enable/Disable of Extended Socket to each Extended Partition can be set by MMB Web-UI.
Extended Socket has the Zoning function.
Zoning function is the function that an Extended Partitions can communicate by using Extended Socket with
only particular Extended Partitions which is allowed to communicate.
In Extended Socket, there is “Zone” which is communication group. Zone is set to each Extended Partition.
Communication among only Extended Partitions which belong to same Zone is allowed.
Zoning function can be set to each EP by MMB Web-UI.
VLAN (tag-VLAN) function is the function that separates traffics within a divided zone. VLAN (tag-VLAN)
function can be set by OS on the EP.

Memory Scale-up Board
Memory Scale-up Board is the board for expanding memory without increasing CPU.
Memory Scale-up Board is supported in only PRIMEQUEST 2400E3/2400E2.
Up to three Memory Scale-up Board can be installed.
For the details on the Memory Scale-up Board, see ‘
Use conditions of the Memory Scale-up Board
If you include Memory Scale-up Board into a partition, at least one SB must be included in the partition.
If you include Memory Scale-up Board into a partition, you must install CPUs other than Xeon ® E7-8855v4
and E7-8860v3 on SB.
Note
-
Memory Scale-up Board cannot be set to Home SB.
-
Memory Scale-up Board cannot be set to Reserved SB.
-
Extended Partitioning cannot be used in the partition including Memory Scale-up Board.
-
Memory Scale-up Board cannot be hot added and hot removed by Dynamic Reconfiguration.
-
Dynamic Reconfiguration cannot be used in the partition including Memory Scale-up Board.
Memory Scale-up Board does not switch to Reserved SB even if Reserved SB is set in the partition.
