007-4857-002 67 Chapter 3 3. System Overview This chapter provides an overview of the physical and architectural aspects of your SGI Altix 450 system. The major components of th e Altix 450 series systems are described and illustrated.
68 007-4857-002 3: System Overview Figure 3-1 SGI Altix 450 System (Short Rack) System Models The basic enclosure within the Altix 450 system is the 5U high (8.68 inch or 22 cm) “individ ual rack unit” (IRU). The IRU encl osure houses a maximum of four single-wide blades and one double-wide blade.
System Models 007-4857-002 69 Figure 3-2 SGI Altix 450 Server System (T all Rack) Y o u can also add addi tio nal PCI expansion blades or RAID and non-RAID disk storage to your server system.
70 007-4857-002 3: System Overview Figure 3-3 Blade, IRU and Rack Components System Architecture The Altix 450 compu ter system is based on a dist ributed shared memory (DSM) architecture. The system uses a global-address-space, cache-coherent multipro cessor that scales up to 76 Intel 64-bit processor cores in a single rack.
System Architect ure 007-4857-002 71 interface. The SHub ASIC memory interface enables any processor in the system to access the memory of al l proce ssors in the syst em. Another component of the NUMAlink 4 archi tecture is the router ASIC. The router ASIC is a custom designed 8-port crossbar ASIC.
72 007-4857-002 3: System Overview System Features The main features of the Altix 450 series server systems are intro duced in the followin g sections: • “Modularity and Scalability” on page 72 .
System Feat ures 007-4857-002 73 Memory latency is the amount of time requ ired for a processor to retrieve data fro m memory . Memory latency is lowest when a processor accesses local memory .
74 007-4857-002 3: System Overview Non-uniform Memory Access (NUMA) In DSM systems, memory is phys ically located at various distan c es from the processors.
System Feat ures 007-4857-002 75 • Power -on and boot: – Automatic testing occurs after you power on the system. (These power-on self-tests or POST s are also referred to as power-on diagnostics or PODs). – Processors and memory are au tomatically de-allocated when a self-test failure occurs.
76 007-4857-002 3: System Overview System Component s The Altix 450 series system featur es the following major components: • 20U rack. The “short” rack is a custom rack used w ith the Altix 450 system. It holds up to 4 IRUs or a combination of IRUs and option modules (such as mass storage).
System Components 007-4857-002 77 Figure 3-5 Altix 450 IRU System Components Example Bay (Unit) Numbering Bays in the racks are numbered using standard units .
78 007-4857-002 3: System Overview Optional System Component s A vaila bil ity of opti onal components for the SGI 450 sy stems may vary based on new prod uct introductions or end-of-life compo nents. Some opti ons are list ed in this manual, others may be introduced after this document goes to produ ction status.
007-4857-002 79 Chapter 4 4. System Control This chapter describes the interaction and func tions of system contro llers in the fol lowing sections: • “Levels of System Control” on page 80 • .
80 007-4857-002 4: System Control Figure 4-1 SGI Altix 450 System Control Network (Example) Levels of System Control The system control network config uration of your se rver will depend on th e size of the system and control options selected. T ypically , an Ethernet connection to the system controller network is used.
System Controller Interaction 007-4857-002 81 The system controller is designed into all IRUs. An Ethernet connectio n directly from the IRU to a local private or public Ethernet allows the system to be administered direct ly from a local or remote console.
82 007-4857-002 4: System Control L1 Controller Functions The following list summarizes the con trol and monitoring fu nctions that the L1 controller performs: • Controls voltage m argining within t.
Ethernet Swit ch 007-4857-002 83 The front panel d isplay contains the fol lowing items: • 2 x 12 character liquid crystal display (LCD). The display id entifies the IRU, shows system status, warns of required service, and identifies a failed com ponent.
84 007-4857-002 4: System Control Console Hardware Requirement s The console type and how these conso le types are connected to the Altix 450 servers is determined by what console option is chosen.
