Notes:
1. All final customer configurations and solutions require IBM Solution Assurance Approval.
2. The Datacenter OS comes preloaded on each High Availability (HA) DC model.
3. Select one model to serve as the primary server. The OS will reside on this server.
4. Select based on primary server selected. x3950 E COA must match the selected x3950s OS.
5. Order both cables in quantities shown per configuration. Connects chassis in a node together for
scalability.
6. x3950 Datacenter models ship standard with the maximum number of processors. The x3950 Es OS have
zero processors standard.
7. All processors in the solution must match. Select processors for the x3950 E based on processors installed
in the primary x3950. Select in quantities of four per x3950 E.
8. This option is applicable for models 8872-7AY, 8872-7BY, 8872-8AY, 8872-8BY, 8874-3AY and 8874-3BY
only.
9. HA solution x3950 and x3950 E Datacenter models have zero DIMMs standard. Minimum of two DIMMs
(one option kit) equating to 4GB required per chassis. Each chassis must contain the same memory
configuration.
10. All Datacenter models ship standard with two memory cards. Each memory card supports four DIMMs.
Max of four cards are supported per chassis.
11. Memory can be installed using one of two methodologies: Performance installation or cost-effective
installation. Performance installation populates one pair of DIMMs per memory card, until four cards are
installed, before adding a second pair of DIMMs to a card. Cost-effective installation fully populates each
memory card before adding additional cards.
12. Single core Datacenter solutions containing greater than 16 processors require one Scalability
Enablement/Memory Adapter (P/N 41Y5004) per chassis. x3950 E dual core Datacenter solutions
containing 16 processors and greater require one Scalability Enablement/Memory Adapter (P/N
41Y5004) per chassis. Proof of the appropriate U.S. Government Export License must exist before this
option can be ordered or shipped to Tier 3 countries. In addition to providing scalability support, this
adapter supports four memory DIMMs and can be used in place of one of the standard, four-slot
memory adapters.
13. This option kit includes the components necessary to upgrade systems that currently have single-core
Intel Xeon MP processors installed to support the dual-core Intel Xeon MP processors. Processors are not
included in the kit and must be purchased separately. Once the system is upgraded, the new system
model type must be registered with IBM. Directions for registering the new system model type are
included in the option.
14. A maximum of two ServeRAID 8i controllers is allowed per Datacenter node (each instance of the
operating system). One of the two ServeRAID 8i controllers must be installed in the x3950. The other
ServeRAID 8i controller can be installed in an x3950 E to fit your configuration.
15. Minimum two identical HDDs required on primary server (x3950) for OS. HDDs are optional for x3950 E.
Max = 6 HDDs per chassis.
16. Minimum two required per primary server (x3950) for load balancing and redundancy. Optional for
x3950 E.
17. One required per chassis for service processor interconnection. The service processors of all chassis must
be connected together via an ethernet network.

Note: Refer to the Required Service Offerings section at the end of the Datacenter section for any manufacturing
install fees that may apply.
Note: A node represents a single instance of the operating system. For example, a single-node, 16-way configuration
will consist of one x3950 and three x3950 Es.
