Architecture (SX2000 Version)
The architecture of the SX2000 is highly similar at first glance compared to the SX1000, however it has quite a few design differences.
- The hardware clock has been moved from the power-board to the backplane and doubled up for redundancy and greater quality.
- The SX2000 introduced PCI-Express card cages (retaining support for PCI-X 2.0). Maximum of 192 external slots are possible.
- All connections have been changed to high speed serial (HSS) connections for greater speed and greater redundancy.
- Three crossbars compared to two crossbars in each quadrant (per four cells) for greater speed.
Similarly to both Legacy and SX1000 setups, SX2000 can be:
- 16-way (four cellboards and two IO-cages can be used)
- 32-way (eight cellboards and four IO-cages can be used)
- 64-way (expands the one cabinet to two-cabinet complex, with 16 cells and eight IO-cages)

Famous quotes containing the word architecture:
“Art is a jealous mistress, and if a man have a genius for painting, poetry, music, architecture or philosophy, he makes a bad husband and an ill provider, and should be wise in season and not fetter himself with duties which will embitter his days and spoil him for his proper work.”
—Ralph Waldo Emerson (1803–1882)
