Computers</b><br>
<br>
<div align="justify"><b>IDC defines</b> capability-class
computers as systems purchased primarily to tackle the largest, most
complex single problems. <br>
<br>
<b>Capability-class</b> HPC systems are generally priced at $2
million to $4 million or more, with costs occasionally approaching or
even exceeding $100 million. <br>
<br>
Traditional symmetric multiprocessor (SMP) technical servers and
supercomputers of sufficient size fall into this category, but
large-scale clusters also qualify as capability-class systems if they
are purchased primarily to address large single problems.<br>
</div>
<br>
<div align="justify"><b>Capacity-class</b> systems are purchased
primarily to solve many small and mediumsized problems. Capacity-class
HPC systems may also be priced at more than $1 million and may include
any category of HPC computer. IDC further divides capacity-class
computers/servers by price band:<br>
</div>
<ul>
<li>Enterprise: $1 million or higher</li>
<li>Division: between $250,000 and $1 million</li>
<li>Department: below $250,000</li>
</ul>
<div align="justify">The primary purchasing rationale
differentiates capability- and capacity-class systems.<br>
