[Xen-users] "Best practice" guest storage setup - iSCSI Storage, few servers, mixed usage

[Götz Reinicke <goetz.reinicke@xxxxxxxxxxxxxxx>]

Hi,

I'm looking for a "best practice" setup or some suggestions and comments 
for the following hardware and applications:
I have two HP DL 360 dual 3GHz Xenon servers with 4GB RAM and two 250GB 
SATA disks each and two 1GB NIC interfaces each. There is no 
hardwareraid controller.
Furthermore I do have an iSCSI storage with 10 SAS harddrives which is 
raid 5 and 6 capable. The raid 6 size is about 1 TB.
The guest should be in first place for software tests e.g. the CMS we 
use or a web application we develop (both LAMPs). There is only one 
person using the development system and the test cms right now. Later 
this could be two or tree users.
The other things are master and slave DNS server and DHCP. We do have 
about 300 Clients, so the load on the standalone servers is minimal.
After reading some of the lists discussions and browsing the web for 
information, I came to the conclusion, that for our setup mounting one 
"large" iSCSI targets each on the HP servers and using disc images for 
the guests is the simpelst and adequate setup.
The other idea was to split the iSCSI raid in to multiple smaler 
targests and use tham as devices for the guests.
Any suggestions?


Thanks and best regards

Götz
