Strategy for Utilizing Scale Out Storage for Cloud & Virtualization Platforms

Hi folks,

I’m finishing up my week at Red Hat Summit, sitting in a coffee shop in downtown San Francisco. I spent the week in customer meetings, pulling booth duty, showing demos, and presenting a handful of sessions.. And here I am with my laptop, and my coffee, writing about my laptop and coffee.. I’ve officially become a walking (sitting?) cliché.

Anyway, as the title suggests this time, I want to cover a great strategy for taking advantage of scale-out storage for virtualization and/or cloud. It’s certainly not the only way, but it works very well. Don’t let the NetApp visuals scare you away – some of what I’m sharing will apply regardless of the scale-out platform you’re utilizing. I’ll point out the things that are likely unique to NetApp. Continue reading

Live Migration of Storage and Storage Connections for KVM & OpenStack

In this most current post, I wanted to cover 2 of the core features of NetApp Clustered Data ONTAP and tie it specifically to how it really helps KVM (and OpenStack) scale. While this is meant to be a tech discussion, not a sales pitch, I can’t help but point out that this article shows you some things you can do with NetApp that you can’t do with any other storage, be it “enterprise” or “commodity”.

Extending SCSI Timeouts in KVM Guests

Hi folks, today’s post will cover something that came up in the last few days at work. Someone was concerned about any lengthy delay affecting the health of his VM’s virtual disk and therefore the VM. We’ve all seen the aftermath – either the VM falls into a “paused” state, or the disk goes into a read-only state. So, how do you extend the timeout value in KVM for SCSI disks? Continue reading

3 kinds of visitors to the OpenStack Summit NetApp booth…

Hi folks,

I had a great time in Hong Kong this last week. Pleasant people, beautiful scenery, and OpenStack too. In reality, I was actually there for the OpenStack Summit that heralded the Havana release of the ever-growing cloud platform. But the people and scenery of Hong Kong will have a lasting affect on me as well. I’ll have a little more on the people and scenery later. Continue reading

Using NetApp Cinder Drivers with OpenStack

Hi folks,

Earlier in the week I talked about how NetApp and OpenStack weren’t such an odd coupling of technologies. I wanted to take things just a little further in this post and show you how to use NetApp storage with OpenStack. Specifically, we’re going to use NetApp storage for Cinder and Glance. And while Glance won’t require anything special, Cinder will require a little driver configuration.

Let’s get to it. Continue reading

OpenStack & NetApp: Not Such an Odd Couple

Hi Folks,

I just got back from LinuxCon, KVM Forum, and oVirt Workshop in Edinburgh, Scotland. I thoroughly enjoyed the conference and the city. It’s always great to see old friends and make new ones. One of the questions that came up frequently, whether asked directly to me or indirectly (overheard), was what is NetApp doing here? The other one was, “why is NetApp getting involved with OpenStack”? The second one seemed to have quite a bit of resentment in addition to the genuine curiosity. Back to that later. Continue reading

NetApp Joins the OVA

Hi folks,

I’m proud to announce that NetApp has formally joined the Open Virtualization Alliance (OVA) as a governing member, joining the founding member companies HP, IBM, Intel, and Red Hat. You’ll have to excuse me while I temporarily put down my “Captain KVM hat” and put on my “NetApp hat”.

I can already hear you ask, “what is the OVA, and why should I care?” (I won’t make you wait for the answer.) Continue reading
