It's _almost_ as easy to create the array at BIOS level. So if installing OM
is gonna 'push' your free space even to a minimally uncomfortable level I'd
probably not do it.
I'm interested in if the existing 80GB array is partitioned at all, and if
so the layout and use(size of parts, %free space, files on it).
re swapfiles: With a brand new set of spindles I would definitely create the
first partition on those spindles as swapfile space (*2, to allow NTFS
performance). I would adjust the swapfile on the OS partition to RAM+20MB
(to allow a crash dump) and probably create another swapfile on the 2nd
array of same size. In both cases setting the min/max values to the same
fixed value (to prevent fragmentation).
My 2nd partition on the new array would be for Exchange\mdbdata. (size of
Exch DB + expected growth, times 2, or maybe 3[to account for unexpected
growth])
Placing these two areas on the 1st two partitions places them at the extreme
outer edge of the HDDs, where fastest performance is expected. I may in fact
combine these two partitions into a single partition but create the swapfile
before moving the Exchange database here. The reason has to do with %free
space. With a 20GB Exchange, an expectation of 100% growth in this during
the life of the server and 4GB swapfile locating the two on a single
partition of, say, 70-80GB would seem reasonable. Before anyone mentions
Exchange defragmentation and its need for 110% free space, yes, I know, but
the temp file location can be specified during this process and could as
easily be elsewhere on the 500 array, also, until that 100% growth occurs we
have room on this partition for this activity.

I see the person before me never installed OPEN MANAGE, but I have the
disks.
Is it pretty easy without OPEN MANAGE or should I install it. If I do how
much space does it take up, because I am adding hard drives because of a
severe shortage of memory on my D partition. I see that open manage is 4
disk, so it seems like it could be upwards of 2 gigs, which wouldn't kill
me,
I could still get by.

Hi,
Pretty much its that simple. Plug in drives, Create array in the RAID
software, Go To Disk Management and create the partition.
Remember to Raid it, (for project work id suggest mirrored) in the raid
software, and it will show up as 1 500gb drive in Disk management
Easy as pie!

Currently I have a Raid 1 with two 80gb harddrives. I have purchased
two
500gb hard drives and I plan to move our project files over to those
drives.
I have a Dell Poweredge 1800 with Hardware Raid, with 6 different
channels.
All I want to do is add the 500gb Harddrives, as a diffrent drive
letter
(meaning I do not want to expand the volumes and span accross the
drives),
and move the data over and tell the users where it now resides. I
only
have
10 users so it doesn't seem like an overwhelming task. But I poked
around
the Raid Setup and DOS, is it pretty much plug in the drives and
create
the
array in the program, or am I missing a whole lot of steps. Any
insight
would be great, Thanks.
