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?

Captain KVM speaking at Red Hat Summit 2012

I’m happy to announce that I have been invited to speak at the 2012 Red Hat Summit in Boston!! Here are the details:

Deploying Oracle on Red Hat Enterprise Virtualization 3.0 & NetApp

Jon Benedict (Captain KVM) Senior Solutions Architect/TME, NetApp
Karthik Nagalingam Reference Architect, NetApp

Red Hat Enterprise Virtualization 3.0 ups the ante in enterprise-class virtualization and NetApp provides a flexible and high-performance storage platform. Combining these best-of-breed technologies makes for a compelling platform for tier-one applications.

One of the most prevalent tier-one applications is Oracle 11g. In this session, Jon Benedict and Karthik Nagalingam from NetApp will describe how to virtualize an Oracle database on Red Hat Enterprise Virtualization 3.0 and NetApp. They will demonstrate how to:

  • Effortlessly move a virtual instance to a physical server and back again to ease Oracle support requirements
  • Deploy Oracle in a manner that does not incur unnecessary license fees
  • Backup & Restore Oracle from the storage array

Summit Track: “In-Depth”
Date: Thursday, June 28, 2012
Time: 4:50pm – 5:50pm

Hope to see you there!!

Ethernet Storage vs Fibre Channel Storage

If you’ve followed me at all via my blog, trade shows, or industry whitepapers then you know I work for the storage company with the big blue “N” for a logo. You probably also know how much enjoy working at the the big blue “N”. That being said, I’m about to step away from the party line. And I’ll give you a hint – this article is heavily slanted towards Ethernet.

People ask us all the time, which protocol is best for virtualization? The official answer is “The one(s) that you feel comfortable with, Mr. Customer.” It’s really not a cop out, as we’re actually comfortable with all of them. The truth is that the protocol is not the solution, it’s only the conduit to the goodness that is contained within the storage with the big blue “N”. Here’s where I break from the party.

I don’t like Fibre Channel.

Booting RHEL 6 from NetApp iSCSI

Today we’re going to take a look at booting RHEL 6.1 x86_64 from a NetApp iSCSI LUN, but first we’re going to take a look at why we would want to do this in the first place.  Sure, it’s cool from a techie standpoint, but to do this in the data center requires a compelling argument.
