Frequently Asked Questions
Q: Can an end user expand the cache memory?
A: We recommend that the memory expansion be done by Advantech
because post-testing procedure is necessary after cache memory
expansion.
Q: If a fan or power failure occurs, will the pager "beep" me or send me
a fax to inform me of the problem?
A: NO! The system will page/fax alarm messages only if the hard disk
drive fails. This function is enabled in the setup utility.
Q: Is it possible to have different capacities of hard disk drives?
A: YES! But the total capacity will be the smallest size of all hard disk
drives multiplied by the number of hard disk drives in the RAID
subsystem.
Q: Is it possible to on-line add a new hard disk drive into an empty slot
or on-line change the RAID level?
A: You can on-line add a spare hard disk drive into an empty slot but it
will not expand the total capacity of the RAID subsystem; this
function will be available in the near future. On the other hand, on-
line changing the RAID level is definitely not allowed.
Q: While dialing the pager through a modem, is it possible to use ","
between digits to stop for a second?
A: YES! Especially when dialing out through PABX, it is necessary to
use "," to wait for the PABX to catch the trunk. We also suggest
that you fill the code field of the pager with "#,,,xxxxxxxx#". This will
allow the RAID subsystem to wait for 3 seconds after the pager
number is dialed out, then send out the "xxxxxxxx" eight digits that
will be shown on the pager.
Q: Can RAID-800S support multi-host and multi-array - for example
host1 deploys RAID level 1, and host2 deploys RAID level 5?
A: YES, RAID-800S supports these functions because it has two host
channels and at most can create four arrays (levels).
