Using mirrored disks instead of RAID5 for data dir

Hi.
Lotus recommends using RAID5 for the data dir in a Windows environment (See
KB#7003245) but the server that was purchased for me by our Windows server
administrators is set up to have the data placed on a  mirrored drive set
instead of RAID5 drive set.  I don't have much knowledge on the hardware
side of things, so all I can do is show them the KB article and they say
that mirroring is better now and that it's ok to do this.  Is Lotus'
recommendation to use RAID5 rather than mirrored for the data dir outdated?
TIA,

Mirroring is fine unless you're pushing the limits of your disk i/o
capacity.  Best performance will come from striping with  and
Lotus recommended RAID-5 because it has redundancy which
RAID-0 (simple striping) doesn't provide.  Best performance with
redundancy would could from RAID-10 (which combines mirroring
and striping -- aka "RAID 1+0" or "RAID 0+1") but Lotus wouldn't
make this a general recommandation since it is not supported by
as many vendors and is the most expensive option.

Re: Using mirrored disks instead of RAID5

RAID can provide data redundancy to back up your data and it
can provide improvement in disk efficiency by reading and
writing data across multiple drives.  In some kinds of RAID
it can do both.

First, how many drives does your server have?  You must have
at least three to do RAID5, and five or six drives is usually
preferred.  If you have only two, there wouldn't have been
a choice between mirroring and RAID5; you could choose between
mirroring with 100% data redundancy, halving your total
storage capacity, or striping, greatly improving disk
efficiency.

If you have three or more drives, you can use RAID5, which
provides both redundancy and improvement in efficiency, with
some overhead loss of total capacity.  RAID5 often uses
a hot spare strategy, where one drive of an array sits on the
sideline, ready to nearly instantaneously substitute for a
failing drive.

RAID can be implemented either at the hardware or software
level.  If you have sufficent drives to exploit RAID5, 
typically the system can be reconfigured to do RAID5.

If you are interested in finding our more about RAID options,
the beginning of the manual for IBM's ServeRAID controllers
has a decent explanation of the different types of
RAID and the tradeoffs.  You can download one of these manuals at:

R5 Resource Reservations

All:

We are running R5.0.7 Server on Windows 2000, our Notes clients are R5, 
with a few R6's thrown in for good measure. Late last week, we found that 
our Resource Reservations DB was giving the error "No resource/room found 
for times and/or capacity requirements." On Friday, I renamed Busytime.nsf 
and restarted the server. That didn't fix the error. I found TechNote 
175157, and went through the Troubleshooting Script. The NAB has the 
$Rooms and $Resources views and they are correct. The Site Profiles do not 
have commas in them. All local NAB's have the correct Notes Mail Domain in 
them. I think that I have exhausted all of the troubleshooting items, and 
still we can't reserve any rooms. All of the users are still getting the 
"no resource/room...." error.

Is there something else that I should try?

Thanks.

Gregg

Re: Controlling document deletion


As soon as I pulled the trigger, I realized I forgot the release -- we are
still on 6.0.2CF1 server and most clients.

Re: Antwort: Re: Antwort: Tables in LS

Thanks, Jens. I did eventually get it to work, but am now adopting your
getCell function in place of computing the cell number in place each time.

Re: Error: Plugin Not Found - JavaScript

We've experienced the same problem.  The only solution we've found, other
than removing the site from the Welcome Page, is to switch the browser from
IE to Notes w/IE.  We put it a ticket with Lotus; I think their response
was that it would be fixed in R7.
