We ended up going with option 4.

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

Access and distribution will be Arista and core is Brocade.

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...

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.

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

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...

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

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.

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...

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...

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

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...

You would be surprised what people accidentally delete. Here are some items to restore. 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...

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.

I commented about this in your other post about the DC. Same applies here. Most likely your infrastructure, but would need more information.

I disagree. While I would probably never do a full restore of a DC, the granular recovery options with Veeam is a nice feature. As for the snapshots being left, there is probably another issue you may not be seeing that is causing that problem. I had this issue quite a bit with Veeam 7 when...

Need to know for sure that this motherboard with an LSI 3008 HBA will support CentOS 6.8. On Supermicro's website, they only list version 6.6 and 7.0 for 64 bit support. https://www.supermicro.com/support/resources/OS/C612_X10_list2.cfm Version 6.8 isn't even listed, so I am guessing it was...

Curious, what kind of storage are the VMs running on? Using something with compression and deduplication should drastically cut down the amount of space used.

Good RAID card with caching also helps.

Interesting... Definitely above my networking/security skill set. I am curious of use cases for this.

Then maybe it my lack of understanding. I read it as the OP has hosts on subnet 1 that he doesn't want to respond to pings on subnet 2. We use ACLs to block ports and ICMP between subnets all the time.

Switches and routers we work with most definitely filter ICMP.

Why not just have the network team take care of this at the switch/router level? Pretty easy to do and also where it should be done.

Bump. Great price for what you are getting!

Bump and price lowered.

I would think you can at least send VMware the core dump file and they can tell you what caused the PSOD. They are simply just reading the file.

I would prefer to sell the entire server, but will consider breaking it down if there are no buyers. I am currently running ESXi 6.0 on it. The server resides in a datacenter and has never crashed. Some parts are newer than others. Below is a break down of all the parts. Chassis: Supermicro 2U...

I bought a used 24 port Cisco 3750 on eBay for $300. I specifically bought it for layer 3.

Both actually. We are a cloud service provider. Customers all stayed the same. Our management network was new IP space since I built out many new servers as part of the upgrade/move.
