Howdy,
We will be implementing a new GIS application that will store all it's data in an Oracle 10R2 spatial database. Database server will be running Windows 2003 R2. There will be 10 users using the application with future growth increasing it to 25. I've read many posts about Oracle licensing and supportability and I am comfortable with this aspect. My questions revolve around design and hoping you guys can offer some suggestions.
Current Hardware
ESX Hosts (2)
Model: HP DL385 G2
CPU: (2) AMD Opteron 2218-Dual Core
RAM: 22GB
HBA: QLogic 4052c
NIC: NC360T (Dual Port)
SAN
EqualLogic PS100E, Raid50
I will be ordering a new PS100E and it will be configured for RAID 10 to ensure that the SAN is configured for optimal disk access. This SAN will also be used for future databases such as Exchange (100 users) in the future.
The OS will reside in a VMDK, but I'm not sure if I should be using VMDKs or RDMs for the database disk. Or should I create a LUN, install the MS iSCSI initiator in the guest and connect directly to the LUN. I've read that this is best option for performance and is recommended by EqualLogic.
How do the above guest configurations affect VMotion/HA/DRS?
