Hi,
we have a V880, dual 900 MHz processors, 4GB RAM running Solaris 8, with
recommended patches as of Jan. 3. this is our campus WebCT server and
we're running WebCT CE 3.7.3.4. this is running fairly well, except
that disk throughput is not nearly as good as i'd expect to see.
currently we have just the 6 internal 72GB disks that came with the
system.
in an effort to increase performance and redundancy, we're looking to
add an X6727A Dual FC-AL card. this is at the suggestion of the FAQ at
http://www.sun.com/servers/entry/880/faqs.html#4. this FAQ mentions a
second disk backplane, the dual FC-AL card, cable and the Veritas Volume
Manager. due to the high cost, we are not considering the second disk
backplane, or the Veritas software.
my questions are:
1. can anyone tell me what kind of performance improvement the
additional card might make?
2. what do we lose by not adding the Veritas software? note that we can
handle short downtimes if we did have hardware problems.
3. also, can we do this without the second disk backplane? obviously we
lose the redundancy that offers, but i'm guessing this is a very
expensive option. also backplanes should be pretty reliable, right?
4. any additional comments or suggestions?
thanks! -john
