<strong>WebPAM</strong> <strong>User</strong> Manual<br />
Can I use my existing <strong>WebPAM</strong> setup to monitor a <strong>Promise</strong> subsystem<br />
product also?<br />
No. <strong>Promise</strong> subsystem products, such as UltraTrak and VTrak, have a more<br />
advanced version of <strong>WebPAM</strong> tailored to their designs.<br />
Why do the Rebuild, Synchronize, Expand and Migrate operations take so<br />
long compared to moving data?<br />
When data is moved, the operation consists of reading, writing and checking<br />
one or more files. Rebuild, Synchronize, Expand and Migrate involve<br />
reading, writing and checking all the logical block addresses or individual<br />
data blocks on each disk drive. Plus, your disk array remains available while<br />
these operations take place. These added requirements increase complexity<br />
and take more time.<br />
<strong>WebPAM</strong> documentation uses the term “logical drive” where earlier<br />
<strong>Promise</strong> products use the term “array.” Why did this change happen?<br />
A disk array is an organized collection of physical disk drives. Logical drives<br />
are made from disk arrays. A logical drive is the entity that your operating<br />
system recognizes as a single volume (as if it were a single disk drive).<br />
<strong>Promise</strong> uses the term “logical drive” to keep things as simple as possible.<br />
Can I run <strong>WebPAM</strong> without a network connection?<br />
Yes. You can run <strong>WebPAM</strong> without a network connection but only from the<br />
Host PC. See page 27.<br />
