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? Continue reading →

Hi all,

I have some updates on my Red Hat Summit session that I’d like to share. This will be my 3rd year in a row that I’ve presented, and I’m bringing friends from both NetApp and Red Hat to discuss “Scaling Out Tier-1 Applications with Red Hat Enterprise Virtualization & Clustered ONTAP”.

So what exactly does that mean? Continue reading →

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 →

Hi folks,

My last post was about creating channel bonds, virtual bridges, and VLANs in order to make the best use of 10GbE. This time around, we’re going to apply the same logic and planning to a Red Hat Enterprise Virtualization (v3.1 if you’re interested) environment.

Hi folks, it’s been a few weeks since I posted anything. It’s been busy for me as I’m in the middle of the biggest project that I’ve ever lead. It’s got huge implications, and while I’ve dropped some not so vague hints, I want to show you one tiny aspect of it today:

Effective use of 10GbE using VLANs and Channel Bonding

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. Continue reading →

Hi folks,

Here’s my next info blurb about RHEV 3.1 – this time it has to do with “Power Management” configuration for a Cisco UCS Blade. It’s another case of initial frustration until you finally figure it out and it finally makes sense. It’s also a case of “there really isn’t much help out there”… Continue reading →

Hi folks,

Today I’d like to show you a quick way of tuning your Linux-based virtual machines using the “tuned-adm” command. This command should work with any distribution of Linux on any virtualization platform. Before I show you how to use the command though, I’d like to provide you with an explanation of what is going on under the covers. Continue reading →

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 →

Use Cases for Both RHEV Snapshots and NetApp SnapShot copies

Hi folks,

In one of my previous posts, I mentioned that I would start review some of my favorite new features in RHEV 3.1. This week I tackle the first topic: Live Snapshots. But I can’t leave well enough alone; I also compare it to NetApp SnapShot copies. Not to show that one is better than another – only to highlight different use cases. Read on!! Continue reading →
