Thoughts/experiences of SAN attaching V880 to EMC SAN
Hi everyone,
I wonder if I can canvas any opinions or thoughts (good or bad) on SAN attaching a SUN V880/490 to an EMC Clarion SAN?
At the moment the 880 is using 12 internal FC-AL disks as a db server and seems to be doing a pretty good job. It is not I/O, CPU or Memory constrained and the internal disks are mirrored in a RAID 0+1 configuration.
I have 2 choices to make as we intend to increase the number of db's running on the machine(s) - these options are:
1 - To directely attach the servers to the EMC SAN with FC HBA's.
2 - To purchase StoredgeTek SCSI shelves and use SVM to manage the disks (FCAL is overkill to be honest).
I know there are all sorts of ways the SAN can stripe and chop up the disks to allow for RAID 5 etc and that SVM will make a pretty good job of doing the same on the SCSI shelves.
However I do not know if there are any significant technical advantages/disadvantages for either of these two methods.
Does anyone have any thoughts on this?
My own concerns are the reliability of the connection to the SAN as apposed to directly attaching the SCSI shelves. I feel keeping the SUN kit self-contained may be preferable in the long run.
Appreciate the time taken to read and reply.

mkqdisk
mkqdisk(8) Quorum Disk Management mkqdisk(8)
NAME
mkqdisk - Cluster Quorum Disk Utility
WARNING
Use of this command can cause the cluster to malfunction.
SYNOPSIS
mkqdisk [-?|-h] | [-L] | [-f label] [-c device -l label] [-d [-d ...]]
DESCRIPTION
The mkqdisk command is used to create a new quorum disk or display existing quorum disks accessible from a given cluster node.
OPTIONS
-c device -l label
Initialize a new cluster quorum disk. This will destroy all data on the given device. If a cluster is currently using that device
as a quorum disk, the entire cluster will malfunction. Do not run this on an active cluster when qdiskd is running. Only one
device on the SAN should ever have the given label; using multiple different devices is currently not supported (it is expected a
RAID array is used for quorum disk redundancy). The label can be any textual string up to 127 characters - and is therefore enough
space to hold a UUID created with uuidgen(1).
-f label
Find the cluster quorum disk with the given label and display information about it.
-L Display information on all accessible cluster quorum disks.
-d Increase debugging level. Specify multiple times for more information. Currently, specifying more than twice has no effect.
