Speaking from a purely performance oriented perspective I would consider one
of the two following designs for a CF-only box. I am assuming an Intel box
running Windows NT or 2000 Server.
Here are the things I think you would need regardless of final
configuration:
* Mobo that supports 133MHz bus/RAM
* Dual 800MHz+ Coppermine or Xeon processors
* 2GB 133MHz ECC RAM
* (2) Intel Pro 100+ Dual Port NIC's
* Redundant power supplies, >= 300W
* Redundant, and abundant cooling
* Good UPS
* Good multi-channel RAID controller that supports Ultra160.
Make sure it has plenty of cache, >= 128MB
(3)+ Channels would be best
* Enable write caching on your RAID controller and HD's.
* Make sure to use some external backup medium.
* Recommended HD's: Seagate Cheetah X15 ST318451LW 18.4GB
##############################################
# No redundancy
A. RAID channel 0. (2) HD's, RAID 0, stripping. Contains OS, IIS, CF, etc.
B. RAID channel 1. Contains OS swap file and /temp space
C. RAID channel 2. Contains OS, IIS, and CF log files.
Pros:
* Fast read and write performance
* Swap file and log operations are offloaded to dedicated drives
* Allows independent upgrade/swapping of functional units (data, swap,
logs).
For example, if you need more log room, or want to add redundancy to it,
you only
have to worry about that one drive.
* Efficient use of available drive space
* Relatively inexpensive
Cons:
* No data redundancy.
* If any one drive fails the whole system goes down.
# With redundancy
A. RAID channel 0. (4) HD's, RAID 10 (1+0), mirrored stripe sets. Contains
OS, IIS, CF, etc.
B. RAID channel 1. (2) HD's, RAID 1, mirror set. Contains OS swap file and
/temp space
C. RAID channel 2. (2) HD's, RAID 1, mirror set. Contains OS, IIS, and CF
log files.
Pros:
* Fast read and write performance
* Swap file and log operations are offloaded to dedicated drives
* Allows independent upgrade/swapping of functional units (data, swap,
logs).
* Provides data redundancy and internal fail-over via mirrors.
* Allows for hot-swapping HD's
Cons:
* More costly
* Upgrades require the purchase of more drives
* 50% "loss" of disk space
##############################################
# Other points
* Some will argue that RAID 5 is the panacea of RAID and that it should
always be used but, the fact is RAID 0 is faster overall. If this box
were to be a db server I'd probably used RAID 5.
* The Intel NIC's can be configured to load balance and provide fail-over
support.
* If you feel the need for 4 processors get a mobo that supports it but,
start off with 2 processors. You get a severely diminished return
from more than 2 processors. The overhead of 4+ processors can sometimes
slow things down if they're not used.
* Get the fastest processor you can afford
* Think about future upgrades beforehand and buy more than you need at first

Hello,
=20
A large corporation has asked me to architect build them portal for a =
continent, and I accepted :-). The platform will be Win2000, CF 4.5.1 =
and SQL 7.
=20
It is my personal mission to contribute to the destruction of the myth =
that CF won't scale or handle an enterprise level application. With that =
in mind, I'm looking for every possible way to increase performance =
since small increases become big on a large scale.
=20
So to the point, I have a couple scenarios for server hard disk =
configuration for the Cold Fusion boxes. The images and the databases =
will live on their own machines.=20
=20
Please weigh in with your thoughts, comments and scenario choice.
=20
SCENARIO 1:
1 hard drive (10,000 rpms & SCSI)
1 NTFS partition c: WINNT & CFUSION & pagefile & .cfm files.
2 cpus & 1 gig of ram
=20
=20
SCENARIO 2:
1 hard drive (10,000 rpms & SCSI)
4 NTFS partitions: c: WINNT d: CFUSION e: pagefile f: .cfm files
2 cpus & 1 gig of ram
=20
=20
SCENARIO 3:
2 hard drives (10,000 rpms & SCSI)
2 NTFS partitions drive one c: WINNT d: pagefile
2 NTFS partitions drive two c: CFUSION d: cfm files
2 cpus & 1 gig of ram
=20
=20
SCENARIO 4:
4 hard drives (2 5600 & 2 10,000 rpms & SCSI)
1 NTFS partitioned 5600 drive c: WINNT
1 NTFS partitioned 5600 drive c: pagefile
1 NTFS partitioned 10K drive c: CFUSION
1 NTFS partitioned 10K drive c: cfm files.
2 cpus & 1 gig of ram
=20
=20
SCENARIO 5:
Your combination here....

=20
TIA,
