NFS & Firewalls in RHEL 7

Here is a quick post for you guys. I’m in the midst of creating a follow up to one of my other articles and it dawns on me that I need to do this particular post first.. A post within a post, or before a post, or something. In either case, I need to provide an update to configuring NFS to poke through a firewall in RHEL 7 for the purpose of RHV in a home lab.. or other use cases. Read on, if you will… Continue reading “NFS & Firewalls in RHEL 7”

VSC for RHEV is GA Today!!!

Hi folks,

I’m incredibly happy to announce that after a very long wait and some unexpected delays, the Virtual Storage Console for Red Hat Enterprise Virtualization has officially achieved General Availability status as of today! Continue reading “VSC for RHEV is GA Today!!!”

VSC for RHEV beta is live!

Hi folks,

I’m very happy to announce that the beta for the Virtual Storage Console for RHEV is officially available for 1 month, starting about an hour ago. I can’t tell you how excited I am about this as this integration has been a long time coming.

So, how do you get in on the beta program? Go to, and either login or register (free) and then login.. (The register button is in the upper right hand corner.) Once logged in, click the button to request being added to the group. Once you are approved, you will see 2 PDF’s and 2 RPM’s. I strongly suggest grabbing all four. Peruse the Release Notes, then move to the Installation & Administration Guide to see how to deploy the 2 RPM’s and get going…

In the mean time, a HUGE shout out to Chris Morrissey, Dustin Schoenbrun, Ricky Hopper, Chris Suich, Rashid Nadaf, Praveena Palaniswamy, Troy Mangum, Patrick Strick, Greg Blaha of NetApp, and Vojtech Szocs, James Rankin, Andy Cathrow, and Ayal Baron of Red Hat. This was a fairly serious endeavor that took the time and efforts of many people in order to pull this together.

Can’t wait for the GA in November!!!!

Virtual Storage Console for RHEV

If you saw me run this demo live at Red Hat Summit this week, I sincerely appreciate you coming to my session.  For those that were unable to make it to Red Hat Summit, you did in fact miss a great event.

The Virtual Storage Console (VSC) for RHEV is something that I’ve been pushing for some time now and we’ve (NetApp) made significant progress. It’s the kind of integration that really does make things easier for Virtualization Admins and even takes a little load off of a Storage Admin. So what exactly is it?

Providing High Availability for RHEV-M

Hi folks, in today’s post I’d like to cover something fairly elementary – providing HA for the RHEV-M application. To be honest, I can’t believe I haven’t written a post on it sooner. If you have power users, VDI users, and/or other services (via API/SDK) that depend on RHEV-M, it’s definitely critical. Besides, providing HA for RHEV-M is just downright convenient, even if it’s just virtualization administrators that need access. Continue reading “Providing High Availability for RHEV-M”

pNFS – This is where the rubber meets the road..

Hi folks,

In October of 2012, I wrote a blog post on using pNFS as a means of scaling out your KVM-based virtualization environment. I kept it mostly high level as I wanted it to be more academic than hands on. Today, I’d like to switch that around and make this post more hands on in order to show you how to attach your pNFS client to a pNFS server.

Mounting NetApp Clustered ONTAP NFS exports in RHEV 3.1

Hi folks,

Just thought I’d update you on something you may need to throw in your bag of tricks. This one has to do with getting a NetApp NFS export mounted and initialized properly in RHEV 3.1. I’m putting this out there as it seems to be just a little different than before and without this little tip you might get frustrated enough to put a pen through your monitor… Continue reading “Mounting NetApp Clustered ONTAP NFS exports in RHEV 3.1”

Using pNFS to Scale Out RHEL & KVM

A few weeks ago, I talked about “Storage Virtualization & Scaling Out Your KVM-based Virtual Infrastructure”. I want to expand on that theme, and I’ll probably do that several times over the next few months.  This time, I’ll focus a bit more on one of the specific ways that we can truly scale on demand with RHEL 6, KVM, & NetApp Clustered ONTAP using pNFS (Parallel NFS).

Storage Virtualization & Scaling Out Your KVM-based Virtual Infrastructure

If you’re using KVM as a major component of your data center infrastructure, at some point you have to consider how you’re going to scale out. How easy is it to grow from 10 virtual machines to 20? How about from 20 to 200? The answers are likely different, but they don’t have to be… Continue reading “Storage Virtualization & Scaling Out Your KVM-based Virtual Infrastructure”
