    We ended up going with option 4.

    Data Center Network Design

    Here are all three options. Option 3 means using core routers for the ESXi hosts to access storage.

    Data Center Network Design

    Access and distribution will be Arista and core is Brocade.

    Data Center Network Design

    I just wanted to see if this network design makes sense or if there is a better way it can be done. The current setup doesn't include the distribution layer, but there is also only one cab with servers and storage. So right now cab 3 goes directly to cab 1 and cab 2. Since I will be adding a 4th...

    What Tool for Automation?

    My bad. I just assume going to ansible.com was the way to go and saw the pretty looking Red Hat Ansible Tower. I now see other instructions for setting it up on CentOS.

    What Tool for Automation?

    Free is definitely preferred. I do keep hearing about Ansible a lot, but it doesn't look like they have a free version.

    What Tool for Automation?

    I am looking for something like Puppet or Chef that can be used for automation. It needs to be agentless, and preferably free or at least not very expensive. I would like it to at least work with Windows and VMware, but support for Linux and network devices would also be nice. I was considering...

    Windows 2012 R2 Failover Cluster with Virtual RDM - Cluster Across Boxes?

    The VSS issue turned out to be a VMware issue with multi-pathing. They disabled multi-pathing and now it is working correctly.

    Windows 2012 R2 Failover Cluster with Virtual RDM - Cluster Across Boxes?

    So although virtual RDMs support snapshots, it is not recommended with bus sharing? What app based backup would you recommend? I believe the physical storage is 3PAR, but they are using DataCore SANsymphony.

    Windows 2012 R2 Failover Cluster with Virtual RDM - Cluster Across Boxes?

    Backups... Have a customer with many physical RDMs and on more than one occasion the VSS writer could no longer take snapshots and therefore Veeam Agent backups would fail. With a virtual RDM I don't have to worry about Microsoft's VSS writer since VMware snapshots can be used with a typical...

    Windows 2012 R2 Failover Cluster with Virtual RDM - Cluster Across Boxes?

    Thanks for the article, but that seems to be the same as the 5.5 article I was reading. Virtual mode only for cluster in a box and physical mode for cluster across boxes. VMFS also only supports cluster in a box. Cluster in a box is only good for guest OS failures and maintenance. No protection...

    Windows 2012 R2 Failover Cluster with Virtual RDM - Cluster Across Boxes?

    Yes. I thought that was pretty obvious from what I wrote. ;)

    Windows 2012 R2 Failover Cluster with Virtual RDM - Cluster Across Boxes?

    It seems difficult to find a solid answer to this question. VMs are running on vSphere 5.5 across multiple ESXi hosts. VMware documentation says both physical and virtual are supported in this configuration but physical is recommended. The same documentation also states, "Clusters across...

Instantly recover individual Active Directory objects or entire organizational units (OUs) and their attributes from a single-pass image-level backup Recover lost user and computer accounts along with their...

    How can you clone an ESXi boot drive?

    Get an external cloner where you put the source and destination drives in it. Makes an exact copy. I had issues with the EFI partition and the external cloner did the trick.
