Figure 3 – <strong>IQ</strong> Main Store Drive Mapping per Multiplex<br />
The disk layout and presentation is not much different <strong>for</strong> an <strong>IQ</strong> temporary store. The above<br />
example of 4 RAID 5 groupings of 5 disks (4 + 1 parity) will be carried through <strong>for</strong> the <strong>IQ</strong><br />
temporary store device example.<br />
The main difference, though, is that the <strong>IQ</strong> temporary store devices are dedicated to a single<br />
host while the main store devices are shared amongst all nodes. It is just as important, though,<br />
to make sure that the temporary store devices <strong>for</strong> each <strong>IQ</strong> server are not sharing disk/spindle<br />
resources with any other <strong>IQ</strong> instance or non-<strong>IQ</strong> application.<br />
