|
<P> Given all these options, if you're looking for a RAID solution,
|
|
you need to think carefully about what you want. Depending on what
|
|
you want to do, and which RAID level you wish to use, some cards may
|
|
be better than others. SCSI-to-SCSI adapters may not be as good as
|
|
host-based adapters, for example. Michael Neuffer (
|
|
<A HREF="mailto:neuffer@uni-mainz.de">neuffer@uni-mainz.de</A>), the author of the EATA-DMA
|
|
driver, has a nice discussion about this on his

<H2><A NAME="ss3.2">3.2 Enclosure type</A>
|
|
</H2>
|
|
|
|
<P> The enclosure type affects the hot swap-ability of the drive, the
|
|
warning systems (i.e., whether there will be indication of failure,
|
|
and whether you will know which drive has failed), and what kind of
|
|
treatment your drive receives (for example, redundant cooling and
|
|
power supplies). We used the DPT supplied enclosures which work
|
|
extremely well, but they are expensive.
