funny how many solutions for NAS/SAN support raid5 but only have a single power
supply. I think NetApp were/are the ones who do it
right.</FONT></SPAN></DIV>

problems with any power supplies. We are using dual power
supplies...doesn't make sense to purchase a reliable file server and not
purchase dual PS or to not to put it on UPS power.</FONT> <BR><BR><FONT
face=sans-serif size=2>Have only had 1 drive failure over the past 8 years of
using NetApp (across 4 filers and 2 different models). Of course I don't
have TBs of data. We are using their small filers in the 250-300G range.
We purchased these filers to store the source code to our products
(company jewels) so reliability and data integrity are very important to
us.</FONT> <BR><BR><FONT face=sans-serif size=2>Based on past experience with
hardware based RAID cards (Dell PERC, AMI, etc, etc), I wouldn't trust the
company jewels to them...I have seen too many blow up and needed to be recovered
from backup. NetApp measures their availability of these filers from the
installed base at 99.99% (< 53min/year) and >99,000 years for Mean Time to
Data Loss (MTTDL). See http://www.netapp.com/tech_library/3065.html</FONT>
