The server is going to be used to store log data for 60 days. Basically the goal is to keep logs from numerous servers in once place. The servers that use the largest amount of data will each have their own filesystem on their own volume groups.
The systems which produce a smaller volume of records will be on separate smaller volumes. The Servers are HP DL360 G7's, and the san is an HP P2000 G3, using fibre channel.
On the SAN we have a total of 12 disks (to start), split into two 6-disk RAID 5's. Adding additional disk shelves, we will continue doing the same thing. We're using 7200 RPM 2TB midline drives since this is just going to be used for data warehousing. We have these RAID 5's carved into single 1TB volumes. These will each get added to the storage server. We'll turn them into LVM physical volumes with PVcreate. Then, we'll create separate the 6 separate volume groups out of them.
Right now we're looking at having 6 separate filesystems running on 6 separate Volume Groups. The largest could be over 25-30TB. The smallest will probably be around 1-2 TB.
We've based this on load testing, but we don't have the ability to fully load test what the system is meant to handle outside of production so certain things (DB archive logs) we can't really get an idea about. Atm we're just scaling up the numbers we're seeing but that's fuzzy math.

This is awesome advice actually. We were running into issues when testing putting a LVM partition on the lun. It wasn't showing up, and partprobe wasn't working. Only thing that worked was a reboot, and that won't be acceptable in production. Just tried using a whole lun instead of a partition and it worked like gangbusters.

NAME
fp - Sun Fibre Channel port driver
DESCRIPTION
The fp driver is a Sun fibre channel nexus driver that enables fibre channel topology discovery, device discovery, fibre channel adapter
port management and other capabilities through well-defined fibre channel adapter driver interfaces.
The fp driver requires the presence of a fabric name server in fabric and public loop topologies to discover fibre channel devices. In pri-
vate loop topologies, the driver discovers devices by performing PLOGI to all valid AL_PAs, provided that devices do not participate in
LIRP and LILP stages of loop initialization.
CONFIGURATION
The fp driver is configured by defining properties in the fp.conf file. The fp driver supports the following properties:
mpxio-disable
Solaris I/O multipathing is enabled or disabled on fibre channel devices with the mpxio-disable property. Specifying mpxio-disable="no"
activates I/O multipathing, while mpxio-disable="yes" disables the feature.
Solaris I/O multipathing may be enabled or disabled on a per port basis. Per port settings override the global setting for the specified
ports. The following example shows how to disable multipathing on port 0 whose parent is /pci@8,600000/SUNW,qlc@4:
name="fp" parent="/pci@8,600000/SUNW,qlc@4" port=0
mpxio-disable="yes";
manual_configuration_only
Automatic configuration of SCSI devices in the fabric is enabled by default and thus allows all devices discovered in the SAN zone to be
enumerated in the kernel's device tree automatically. The manual_configuration_only property may be configured to disable the default
behavior and force the manual configuration of the devices in the SAN. Specifying manual_configuration_only=1 disables the automatic con-
figuration of devices.
