3: System Overview
System Components
The SGI UV 2000 series system features the following major components:
• 42U rack. This is a custom rack used for both the compute and I/O rack in the SGI UV 2000
system. Up to four IRUs can be installed in each rack. There is also space reserved for a
system management node and other optional 19-inch rackmounted components.
• Individual Rack Unit (IRU). This enclosure contains three power supplies, 2-8
compute/memory blades, baseIO and other optional riser enabled blades for the SGI UV
2000. The enclosure is 10U high. Figure 3-5 on page 45 shows the SGI UV 2000 IRU
system components.
• Compute blade. Holds two processor sockets and 8 or 16 memory DIMMs. Each compute
blade can be ordered with a riser card that enables the blade to support various I/O options.
• BaseIO enabled compute blade. I/O riser enabled blade that supports all base system I/O
functions including two ethernet connectors, two SAS ports, one BMC ethernet port and
three USB ports.
Note: While the baseIO blade is capable of RAID 0 support, SGI does not recommend the
end user configure it in this way. RAID 0 offers no fault tolerance to the system disks, and a
decrease in overall system reliability. In a RAID 0 configuration, failure of either system disk
will result in data being lost on both disks, resulting in system shutdown. The SGI UV 2000
ships with RAID 1 functionality (disk mirroring) configured if the option is ordered.
• Dual disk enabled compute blade. This riser enabled blade supports two hard disk drives
that act as the system disks for the SSI. This blade must be installed adjacent to and
physically connected with the baseIO enabled compute blade. Jbod, RAID 0 and RAID 1 are
supported. Note that you must have the baseIO riser blade optionally enabled to use RAID 1
mirroring on your system disk pair.
• Two-Slot Internal PCIe enabled compute blade. The internal PCIe riser based compute
blade supports two internally installed PCI Express option cards. Either two half-height or
one half-height and one full-height cards are supported.
• External PCIe enabled compute blade. This PCIe enabled board is used in conjunction
with an exteranl PCIe expansion enclosure. A x16 adapter card connects from the blade to
the external expansion enclosure, supporting up to four PCIe option cards.
Note: PCIe card options may be limited, check with your SGI sales or support representative.
