Basic steps using vmware ESXi on twin physical servers to create high availability cluster

Implementing our first installations of ESXi 4.1; development testing has gone well and done.  Have twin servers, Proliant with RAID.  P2V and other virtualizations are tested complete, time to clean up and go live.  Question is simple checks and steps to cluster the two and best practices in general for the production set up.

Basically, you'll log into vCenter with the vSphere Client, rt-click on the Datacenter and select Create Cluster. Rt-click on the Cluster and go into its Properties to configure HA, DRS, etc. The Availability Guide will show you what you need to configure and help you with settings:

VMware also provides a HA "Best Practices" white paper worth checking out:

Forgot to add that when you're done creating the Cluster, to move your hosts in it, you simply click/drag them up to the Cluster.

if you don't have shared storage (NAS or SAN), then you won't be able to use most cluster-related features like HA, DRS, and FT plus vmotion won't work, either.

I've got a very small, but critical production deployment in progress.  What would be robust entry level NAS option?  Is it just a simple matter of a "Fry's" purchase of an off the shelve NAS appliance or am I short cutting too much?

you probably don't want to use something like that.  you will want something backed by SAS disks for smaller arrays, otherwise your disk performance will quickly become a performance bottleneck when you start scaling up.  If you use alot of SATA disks, you can overcome this, but since it is production you will want to make sure that whatever you choose is supported for ESX 4.1.  You can search the HCL and specify NAS as the type and 4.1 as the version and you'll get a long list of possibilities.  Don't forget you can also use iSCSI as ESXi comes with a software-based driver.

I did a quick search and found DROBOELITE and a few different Promise models can be found for $2500 and up.  There are some reputable dealers out there that deal in used and refurb'd hardware, too, so don't limit yourself to only new.
