designed for SAP Business Suite, powered by SAP HANA (OLTP) workloads.

Models HAx, HBx, HDx include a preload comprising SLES for SAP, IBM GPFS, and the SAP HANA

software stack.

HCx, HEx are add-on models designed to be connected to model HBx or HDx system respectively

to form an eight-processor system. HCx and HEx include the four QPI cables necessary to join two

systems together to form a two-node complex. HCx and HEx also include the additional GPFS

software and SLES licenses to cover the extra four sockets, but do not include any preload because

the are designed as an add-on to the HBx and HDx offerings respectively.

All H models include either 256 GB, 512 GB or 1024 GB of RAM, SAS disk drives, and a high IOPS

solid-state storage PCIe adapter.

Model 7143-F1x, B9x: These models are designed for virtualization applications and include

VMware ESXi 4.1 Update 1 on an integrated bootable USB memory key. The model comes standard

with the MAX5 memory expansion unit and 384 GB of memory implemented using 4GB memory

DIMMs (256 GB in the server and 128 GB in the MAX5).

F1x is available world-wide and includes a MAX5 V2, 88Y6529. Model B9x is for China only and

includes a MAX5 V2, 88Y6529.

Model 7143-F2x: This model is designed for Open Virtualization and includes Red Hat Enterprise

Linux with the Red Hat Enterprise Virtualization Hypervisor (Kernel-Based Virtual Machine, KVM).

The software is not preloaded. The model comes standard with the MAX5 memory expansion unit

and 384 GB of memory implemented using cost-effective 4GB memory DIMMs (256 GB in the

server and 128 GB in the MAX5).

Refer to the Standard Specifications section for information about standard features of the server.

QPI wrap card

In the x3850 X5, QPI links are used for interprocessor communication both in a single-node system and in

a two-node system. They are also used to connect the system to a MAX5 memory expansion unit. In a

single-node x3850 X5, the QPI links connect in a full mesh between all CPUs. To complete this mesh, the

QPI wrap card is used. QPI wrap cards are installed in sockets where the scalability cables are installed.

The QPI wrap cards are only for single-node configurations with three or four processors installed and only

when a MAX5 unit is not installed. Two QPI wrap cards are needed.
