      <title>Server Clustering with Esxi ( a.k.a. a wad of terminology that is confusing)</title>

      <description>&lt;HTML&gt;&lt;HEAD&gt;&lt;/HEAD&gt;&lt;BODY&gt;&lt;P&gt;I've been using Esxi for about four years and have it running at four sites. All sites are simple, nothing complicated setups and pale in comparrison to what most of y'all deal with.&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;With that said, yes, I've RT*M and everything I can find out there on setting up a simple cluster with Esxi 5.1 and I'm confused. All I want it two Windows servers that will function in a cluster so that if one dies (or whever the technical term is....if I understand correctly, a Failover Cluster vs a Load-Balanced Cluster) the other will take its place. I will have the servers on two different physical boxes. Remember, we are trying to do this as inexpensively as possible - small business.&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;Questions:&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;OL&gt;&lt;LI&gt;Can I use the version of Esxi 5.1 I have "Essentials Kit". It shows that it does not have "HA" and I have yet to figure if I have to have "HA" to do this.&lt;/LI&gt;&lt;LI&gt;Some things mention that you have to have shared storage and that you can't uses disk inside the main Esxi boxes. Am I right?&lt;/LI&gt;&lt;LI&gt;I see a "Shared storage appliance" that costs 4k to 5k - ouch.&amp;nbsp; Can a NAS or another physical box running iSCSI server as the shared storage? If so do you need two physical boxes in case one of them croaks?&lt;/LI&gt;&lt;/OL&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;Thanks for any help y'all can provide!&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;Arch&lt;/P&gt;&lt;/BODY&gt;&lt;/HTML&gt;</description>

      <description>&lt;HTML&gt;&lt;HEAD&gt;&lt;/HEAD&gt;&lt;BODY&gt;&lt;P&gt; What Microsoft product are you trying to cluster?&amp;nbsp; Your solution will depend on if it is file/print or Exchange or SQL.&amp;nbsp; With VMware HA you typically just have a single virtual machine and it gets restarted on another host should the host it is running on fail.&amp;nbsp; If you're running clustering at the MS level, then you don't necessarily need HA.&lt;/P&gt;&lt;/BODY&gt;&lt;/HTML&gt;</description>

      <description>&lt;HTML&gt;&lt;HEAD&gt;&lt;/HEAD&gt;&lt;BODY&gt;&lt;P&gt;It will just be a file / printer server. As of right now its also a domain contoller but I can split that off if it throws a kink in the works.&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;Also, I just re-read your answer and am I reading right, HA&amp;nbsp; can take the place of MS clustering?&lt;/P&gt;&lt;/BODY&gt;&lt;/HTML&gt;</description>

      <description>&lt;HTML&gt;&lt;HEAD&gt;&lt;/HEAD&gt;&lt;BODY&gt;&lt;P&gt; With both HA and Windows file clusters you'll need some sort of shared storage.&amp;nbsp; With HA you would have a single file server VM running on a single host.&amp;nbsp; In the case of a host failure, the VM would be restarted on the other host so you would only have a few minutes of downtime.&amp;nbsp;&amp;nbsp; At the higher licensing levels you also get Fault Tolerance in which case the single VM actually runs simultaneously on two hosts, but again this requires shared storage.&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;With a MS file cluster you'll require shared storage so you could do it on a single host, but that would give you a single point of failure.&amp;nbsp;&amp;nbsp; You might be better off deloying two VM on different hosts each with their own storage.&amp;nbsp;&amp;nbsp; Configure DFS to replicate the files between the two servers.&amp;nbsp;&amp;nbsp; You could also double up the server roles on the VMs on run them as domain controllers.&amp;nbsp;&amp;nbsp; Running domain controllers on a MS file cluster is supported, but not recommended.&lt;/P&gt;&lt;/BODY&gt;&lt;/HTML&gt;</description>

      <description>&lt;HTML&gt;&lt;HEAD&gt;&lt;/HEAD&gt;&lt;BODY&gt;&lt;P&gt;Here is the next SNAFU. Server 2008 R2 standard does not come with clustering..you have to jum to enterprise edition which is $$. Server 2012&amp;nbsp; standard comes clustering but doest not work with Vsphere 5.1 (the release notes say "Windows Server 2012 does not support failover clustering")??&lt;/P&gt;&lt;/BODY&gt;&lt;/HTML&gt;</description>

      <description>&lt;HTML&gt;&lt;HEAD&gt;&lt;/HEAD&gt;&lt;BODY&gt;&lt;P&gt; Not to push a solution, but I think DFS would do the trick for you.&amp;nbsp; No clustering setup or maintenance to worry about and you won't need any shared storage either.&lt;/P&gt;&lt;/BODY&gt;&lt;/HTML&gt;</description>

      <description>&lt;HTML&gt;&lt;HEAD&gt;&lt;/HEAD&gt;&lt;BODY&gt;&lt;P&gt;I didnt think of DFS until you mentioned it but being able to solve this delimia was bugging me (and I wanted to learn something in the process!).&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P class="MsoNormal"&gt;With that said, I have learned more about clusters, “shared storage”, “SCSI – 3 persistent reservations”, etc in the last two days than I wanted to (two nights till 2:00AM) but I figured it out!&lt;/P&gt;&lt;P class="MsoNormal"&gt;&lt;/P&gt;&lt;P class="MsoNormal"&gt;Things I learned:&lt;/P&gt;&lt;UL&gt;&lt;LI&gt;Server 2012 is the first standard version of Windows server that is cluster capable (previous version you had to have data center). It is very picky about its shared storage – especially that phrase “SCSI – 3 persistent reservations”.&lt;/LI&gt;&lt;LI&gt;I first tired FreeNAS (most recent version FreeNAS-8.3.0-RELEASE-p1-x64) however Server 2012 failed on the Validate a Configuration Wizard&amp;nbsp; tests due to not having SCSI – 3 persistent reservations.&lt;/LI&gt;&lt;LI&gt;&lt;SPAN&gt;With the help of this link: &lt;/SPAN&gt;&lt;A class="jive-link-external-small" href="http://blog.jamiebaldanza.org/2012/08/14/ubuntu-12-lio-iscsi-target-configuration/"&gt;http://blog.jamiebaldanza.org/2012/08/14/ubuntu-12-lio-iscsi-target-configuration/&lt;/A&gt;&lt;SPAN&gt; I was able to get plain old Ubuntu to host a special version of iSCSI for the shared storage (the version of iSCSI target that works is "lio-utils"). From what I’ve been able to read, normally shared storage devices are very expensive and this worked in a test environment.&lt;/SPAN&gt;&lt;/LI&gt;&lt;/UL&gt;&lt;P&gt;&lt;/P&gt;&lt;P class="MsoNormal"&gt;&lt;/P&gt;&lt;P class="MsoNormal"&gt;Its pretty dang cool. For the heck of it, I connected to the shared storage file share, and started reading files. I rebooted one of the clusters and kept reading the shared storage in the background….it never missed a beat.&lt;/P&gt;&lt;P class="MsoNormal"&gt;&lt;/P&gt;&lt;P class="MsoNormal"&gt;Thus far, I have one part missing and that’s the cluster aware duplicate of the shared storage. I have not tackled it yet.&lt;/P&gt;&lt;P class="MsoNormal"&gt;&lt;/P&gt;&lt;P class="MsoNormal"&gt;Arch&lt;/P&gt;&lt;/BODY&gt;&lt;/HTML&gt;</description>
