Chapter 21. Datacenter solution program 281
Notes:
1. All final customer configurations and solutions require IBM Solution Assurance Approval.
2. The Datacenter OS is not preloaded but is provided "in-box" with each Scalable 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 x3950 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 E has zero
processors standard.
7. All processors in the solution must match. Select processors for x3950 E based on the processor installed
in the primary x3950. Select in quantities of four per x3950 E.
8. This option is applicable for models 88727DY, 88727EY, 88728DY, 88728EY, 88743DY, and 88743EY only.
9. Scalable x3950 Datacenter models have two 2GB DIMMs standard. 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 xSeries x3950 and x3950 E 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

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.
