  • March 11, 2008 Installed a Rocks Cluster on VMware http://www.rocksclusters.com - deployment of compute nodes is a snap
  • vMotion Storage PlugIn works as advertised - this is very powerful for moving _running_ VMs from FC to SATA disk or vice versa depending on the VMs requirements for I/O

  • March 24, 2008 Proof of Concept: snapshot and snapshot replication using 2 solaris 10 VMs running ZFS (use DRS rules to keep the VMs on separate ESX hosts)
    • The ZFS admin web interface runs on port 6789 and makes administration very intuitive.
    • ZFS replication create a local snapshot on the source

zfs snapshot tp1@`date +%Y%m%d`.`date +%H%M%S` 

• initial replication, put dest in read only:

zfs send 20080324.161056  | ssh irt-ascmp-03 zfs receive tp1/tp1
(on dest):
zfs set readonly=on tp1/tp1

• create a new snapshot and do an incremental replication:

zfs snapshot tp1@`date +%Y%m%d`.`date +%H%M%S` 
zfs send -i 20080324.162312 tp1@20080324.162427 | ssh irt-ascmp-03 zfs receive tp1/tp1
