I have 10 mac minis at my disposal. (Currently, I’m booting each device using
a centos6.5 usbstick leaving the 2 disks free for use)
GOAL:
To build a cluster of 10 servers running postgres-xc
EQUIPMENT:
10 mac mini: i7-3720QM@2.60GHz/16G RAM/1x1gbit NIC/2x1TB SSDs (zfs mirrored)
REQUEST:
Please run the software application postgres-xc (a multi-master version of
postgres). I'm told by the DBA that disk IO is the most important factor for
the tasks that he’ll be running. The DBA wants 10 servers each with a 50G OS
partition and a 800GB /data.
THOUGHTS:
I have a few ideas for how to accomplish but I'm unsure which is the best
balance between disk IO and overall IT management of the environment.
QUESTIONS FOR THE LIST:
Should I present each of the 10 mac mini’s mirrored disks to glusterfs thus
creating a large 10TB storage area. Then connect the storage area to
ovirt-engine creating on 10TB storage domain, and use it as the storage domain
for 10 large 800GB disks (a /data for each guest) ?
Should I present each mac mini’s mirrored pair as an nfs share to ovirt-engine?
This would create 10 1TB storage domains. Then create 10 large 800GB /data
partitions (a /data for each guest).
Should I NOT use ovirt and just run each mac mini as a mirrored pair of disks
and a sandalone server?
LASTLY:
I’m open to any other thoughts or ideas for how to best accomplish this task.
Thanks in advance,
