vROPs: Take Cluster Offline: Status: Removing Slice

Applies to vROPs running in NON-HA mode, below was thanks to help from VMware support.  They have an internal KB on this so it should eventually be published or more likely fixed in the future.  Mostly for my own notes, but interesting for those tinkerers out there.

Attempting to remove remote collector node from vROPs to replace w/ larger remote collector.  Correct way would have been to move 'instances' to other collector or data nodes before putting collector node offline.  Instead, I just removed the collector node from the admin console.  That's when it got stuck in this state.

It's supposed to move the 'instances' to other collectors, but that didn't seem to work and it got stuck in a state of taking the cluster offline.  So to remove the remote collector and get back to a stable state, VMware support walked me through below.

Resolution to Case:

Did you know? Running ESXi on Macs has licensing caveats...

Did you know that according to Apple's OS X EULA, you are only allowed to run 2 OS X VM instances per physical device?

So what does that mean for running ESXi on a Mac Pro?  You can only run, legally, 2 OS X VM's on it.


How's them apples?  Kinda sucks, wondering what other people have done to get around this?  Mac Mini value was much better w/ vSAN when it had two internal disks (for the server version).

Really the only option is to talk to your Apple rep and see how you can license more.

Opinion: Nutanix Acropolis and VMware

I was lucky enough to attend the inaugural Nutanix .NEXT conference in Miami the last 3 days.  I learned a lot and met many new faces.  Here is the bottom line:

Nutanix has released their flavor of the KVM hypervisor dubbed "Acropolis".

So what does that mean for you VMware shops?

Right now, possibly lower or complete removal of hypervisor licensing costs.  However, VMware is a leader for a reason, so you will likely need to augment by using something like VMTurbo to manage and give you smarter DRS like capability plus more.  I'll need to read-up on Acropolis feature sets, but the fair comparisons would likely be between the base vSphere ESXi editions (including vCenter)  vs Acropolis/Prism and/or the vCloud Suite vs. Acropolis/Prism/VMTurbo combo.  It's going to come down to features and price.

I'm thinking personally that it "MIGHT" be cheaper to go an Acropolis/Prism/VMTurbo route strictly from a licensing perspective, but have yet to price everything out.  Taking VMTurbo out, I think would most certainly save from a licensing perspective.  The argument may be hardware vendor lock-in, but that is slowly dissolving w/ Nutanix I think.

Through Nutanix Prism software, they even give you the capability of swapping out the ESXi hypervisor w/ the click of a button.  VM's will be migrated to the different hypervisor too, albeit they will be shutdown for the migration process, but looks to be completely automated.

Kinda curious if that is a two way street though.  Meaning, could I change from Acropolis to Hyper-V or back to ESXi?
[Update: Right now, it's a one-way street.  Other things to consider, no cloud stack for Prism/Acropolis to speak of currently.  Still early, but worth keeping an eye on.]

Regardless, all this means, it's an exciting time to be in the infrastructure space.  Hopefully this pushes VMware in the direction of making vSAN a part of the vCloud Suite AND not charging a premium for the 'all-flash' edition of vSAN.  Quite honestly, VERY STUPID move on VMware's part.  it's only shown in that article, so I'm hoping they reverse that idea.  I'm already paying a premium on SSD's and they want me to pay more for licensing!?  Get real.

Right now, technology-wise, I feel Nutanix 'appears' to have the simplicity side of things going for them.  VMware, it's unfortunately quite complicated, but very feature-rich.  The bigger thing that Nutanix will have to worry about though is public cloud adoption.  Yes, they can utilize it too, but will I care?  If I use the public cloud 'efficiently and correctly', on-premise becomes a small pie.

vRealize Operations (aka vROps) formerly vCenter Operations (aka vCOPs) Dictionary

Found this on a community board and well, thought it might be useful to repost.  Also looking to add to this as time permits.

AscendantAny object higher in the "tree", includes parent (and grandparent, great-grandparent, etc)
ParentObject directly above selected object (VM's parent is a host, for example.  Host parent is cluster, etc)
ChildObject(s) directly below selected object in the "tree" (host child(ren) is any VM on host)
DescendantAny object lower in the "tree", include child, grandchild, great-grandchild etc

The above information is useful when creating group objects and what not in vROps.
