Someone doesn't like local storage for large amounts of data
-
Dustin would still need/want to CR that host to another host allowing him to spin up that data very quickly in the case of a failure.
Use tools built for that. GFS2, Gluster, Ceph, Swift, Cinder, etc. The VM would remount after booting in the new host and the storage still fails over.

@scottalanmiller Isn't that part of why we all virtualize so we don't have deal with raw?
No, the idea of putting local storage into files is a post-virtualization concept.

You can still snapshot raw. Raw can be an image file or a volume or a full disk. Raw doesn't mean not virtualized.

Agreed. The problem that is being run into here is one of replication capacity and affects a NAS the same that affects a VM. So you solve both in the same way.
In a VM, you turn to Gluster, et al. In physical you turn to Exablox or similar.

ANd we did, a lot, prior to virtualizing.

Ya I still do for our workstations.

We have two Isilons coming. One is here and ready to be installed. Much easier than managing all of that myself.
Our guys can generate about 20TB a week between them all.

Looked at Isilon a bit a few weeks ago. Definitely nice gear there.

For the price it should be.
-
@stacksofplates Oh yeah, we didn't go with it, not cost effective at all. The price was a bit crazy.

We shaved it down a bit by supplying our own rack, power cables, PDU, etc. They tried to throw all of that in the quote.
Power cables at ~$60 a piece adds up.

There pretty nice. We'd gotten Demo units. We use the VMAX though.

RAWs biggest limitation is you can't storage vmotion it. You can vmotion the pointer but if you are retiring a SAN or something you will be doing it manually.

Ya I'm using KVM so I can either move the raw file or the volume to wherever I need it. It's really simple with qemu and lvm.
