Re: needed cluster for vmware?

Obviously ESX server is not available here, so failover between
physical servers is not available naitively with VMWare server.
"Cluster-in-a-box" is a very low level of protection, since you still
have all your eggs in one backet; if the physical server fails, then
you are out of luck.

VM6 looks interesting, but they only protect if there is a falure of
the physical host server or a system level failure of the virtual
machine. They do not monitor the applications (SQL, Exchange, Oracle,
etc.) running within the VM. They only suport Windows 2000/2003
running in the VM. Also, if your SAN fails then all of your VMs fail.

LifeKeeper from SteelEye Technology is a solution that works in most
virtual environments including: VMWare Server, VMWare ESX Server,
VMWare workstation, Virtual Server 2005 R2 and Zen. LifeKeeper running
within the VM can protect against the failure of a physical server, a
virtual server, the applications running within the virtual server,
network failure and also protect against the failure of your SAN if you
choose to use data replication to copy the data to an alternate storage
device, either another SAN, iSCSI or direct attached storage.
LifeKeeper supports both Windows 2000/2003 and Linux OS.

First of all, I agree with Brian:
If you want to cluster a virtual machine cluster (nodes are guest os)
between two VMWare servers
--> you need VMWare ESX

If you want to cluster a virtual machine cluster (nodes are guest os) within
one VMWare server
--> both VMWare server (freeware, see chapter 7 of manual) and VMWare ESX
will do this for you
(--> you can even do this on VMWare workstation, look for "cluster in a box
on google")

If you want to have VMWare server running in a standard MSCS Cluster group
--> you need VM6 + VMWare server (see
http://www.vm6.ca/product/vmex/default.aspx)

Let me know if this answers your question

You need ESX to do true host clustering...

5x server HP DL 380
1x san HP MSA1000

- SAN storage should hosts all vmware images for all vmware servers
running on all DL servers
- servers should run a vmware server, the images are stored on SAN
storage

anyone has know-how?
