56 IBM eX5 Implementation Guide3.1 Product featuresThe IBM System x3850 X5 and x3950 X5 servers address the following requirements thatmany IBM enterprise clients need: The ability to have increased performance on a smaller IT budget The ability to increase database and virtualization performance without having to addmore CPUs, especially when software is licensed on a per-socket basis The ability to add memory capacity on top of existing processing power, so that the overallperformance goes up while software licensing costs remain static The flexibility to achieve the desired memory capacity with larger capacity single DIMMs The ability to pay for the system they need today, with the capability to grow both memorycapacity and processing power when necessary in the futureThe base building blocks of the solution are the x3850 X5 server and the MAX5 memoryexpansion drawer. The x3850 X5 is a 4U system with four processor sockets and up to 64DIMM sockets. The MAX5 memory expansion drawer is a 1U device that adds 32 DIMMsockets to the server.The x3950 X5 is the name for the preconfigured IBM models, for specific workloads. Theannounced x3950 X5 models are optimized for database applications. Future x3950 X5models will include models that are optimized for virtualization.3.1.1 IBM System x3850 X5 product featuresIBM System x3850 X5, machine type 7145, is the follow-on product to the IBM System x3850M2 and x3950 M2. It is a 4U 4-socket Intel 7500-based (Nehalem-EX) platform with 64 DIMMsockets. It can be scaled up to eight processor sockets depending on model and 128 DIMMsockets by connecting a second server to form a single system image and maximizeperformance, reliability, and scalability.The x3850 X5 is targeted at enterprise clients looking for increased consolidationopportunities with expanded memory capacity.See Table 3-1 on page 62 for a comparison of eX4 x3850 M2 and eX5 x3850 X5.The x3850 X5 offers the following key features: Four Xeon 7500 series CPUs (4 core, 6 core, and 8 core) Scalable to eight sockets by connecting two x3850 X5 servers 64 DDR3 DIMM sockets Up to eight memory cards can be installed, each with eight DIMM slots Seven PCIe 2.0 slots (one slot contains the Emulex 10Gb Ethernet dual-port adapter) Up to eight 2.5-inch hard disk drives (HDDs) or sixteen 1.8-inch solid-state drives (SSDs) RAID-0 and RAID-1 standard; optional RAID-5 and 50, RAID-6 and 60, and encryption Two 1 Gb Ethernet ports One Emulex 10Gb Ethernet dual-port adapter (standard on all models, except ARx) Internal USB for embedded hypervisor (VMware and Linux hypervisors) Integrated management moduleReferring to the models: Throughout this chapter, where a feature is not unique to eitherthe x3850 X5 or the x3950 X5 but is common to both models, the term x3850 X5 is used.
