Is that a nightmare to integrate? Do you put all of your applications on
every server or
do you separate the applications on your servers for core applications such
as office
and line of business applications? I guess what I am referring to is to silo
applications
to make integration easier and take up less disk space.

I have over 40GB of apps on my servers. Had to go RAID5 with three 36GB
drives. Next time I do a refresh, I'll use two 72 or 146GB dirves.

Please respond to

Try running an ERP client like JDEdwards Oneworld. installs run 8Gb or
more. Add full install of Office XP, a few other apps and a swap file to
the mix. A 18gb drive is just too small.

RAID 1 is the way to go for OS /swap. You are right about the wasted
space
on drives these days. 18GB drives were more than sufficient in most
cases.
With 36GB and 54Gb drives and larger you will get more disk space at
the
expense of performance and longer regeneration times.

I agree with the issue on Raid. My favorite config is a 2U server
with
Raid 1. (Dell PE2650)
But, does anyone else get frustrated with the fact that you have to
buy
30+ gig drives these days? It just seems a waste for the OS / swap
volumes! Faster, cheaper, smaller drives would seem like something a
vendor could do well with. I don't think any TS I've built recenty
required more than 6 gigs of space (maybe 12 if you want room for
lot's
of MS hotfixes!).

I agree with you Neil. Sorry to rehash an old thread.
The only significant argument IMO against HW RAID is the added
cost.=20
The controller is "baked in" to a lot of new servers so. this
argument
becomes less compelling. This also counters the "go cheap" SW RAID
alternative to disk redundancy. Disk drives are much cheaper to boot
(no pun intended). I would argue the labor cost to bring a single
disk
TS server back on after a disk crash would certainly pay for the extra
disk. Plus not losing a server out of the farm has plenty of other
benefits (keeping the user from getting kicked out of an active
session
as you stated, not decreasing the performance of the farm by having
the
users from the bad server spread over less CPU's, etc)

You know, I recall a very similar discussion from a while back ;-)
And the flack I got from one guy, particularly, after I stated such,
in
response to the "hardware RAID has no place for TS environments" type
argument ;-)
A relatively cheap and easy way of reducing the likelihood of having
downtime on a TS, even if the users can immediately reconnect to
another
server - in the main, they can't get back the session they just had.
And
for a gain in performance, too, considering that paging is always
gonna
happen, whether you've got ample RAM, or not.
