HP Integrity BL870c i4 Server Blade details

By using the Integrity Blade Link-2, two base blades are combined to scale double the available system resources of a

single BL860c i4. Resources hosted on the ICH MEZZ Card (see figure 2) are not replicated. Refer to table 1 for a view of

the available resources for a BL870c i4. Now physical nPartition is supported.

HP Integrity BL890c i4 Server Blade details

By using an Integrity Blade Link, four base blades are combined to scale to quadruple the available system resources of

a single BL860c i4. Resources hosted on the ICH MEZZ Card (see figure 2) are not optional and not duplicated. Refer to

table 1 for a view of the available resources for a BL890c i4. Now physical nPartition is supported.

Scalable blade technology

HP Integrity server blades offer unprecedented flexibility to scale up your system. Each base server blade features a

Blade Link connector that allows two or four base blades to be connected together to form up to an eight-socket server.

The base blades are connected with Integrity Blade Links. You can choose between two Integrity Blade Link

connectors—Blade Link-2 or Blade Link-4 used to scale to four-and eight-socket systems respectively.

The Integrity Blade Links connect selected QuickPath Interconnect (QPI) ports among processors, the required clocks,

and sideband signals for the system to operate a scale-up multiprocessor system. See figure 3 for link connectivity

representations of the 4S and 8S topologies.
