Hi folks, in this post I wanted to share with you some of the cool activities we have happening next week at the Red Hat Summit in San Francisco. For virtualization there’s a ton of things going on – to say that we are ‘RHV’ed up is an understatement! (sorry, @RedHatRex wrote that joke…) Here’s a short video that will get you goin on RHV:
Welcome to the fourth installment of the ITO series on the Red Hat Enterprise Linux blog. I started the IT Optimization saga with the basics- what does it mean to optimize IT? Then, I illustrated how having the right platform can help modernize your IT infrastructure by not only maintaining stability but also poised towards innovation. Last week, I talked about another key component of every IT infrastructure- Storage and how Red Hat Storage solutions can help your organization modernize storage and reduce cost. This week, let me walk you through a Red Hat offering that can dramatically decrease your IT spending- Virtualization.
Happy Tuesday! Welcome to another new week and brand new post in the IT Optimization series. If you are new here, check out my first post, on what IT Optimization is and the latest post on the demand for a Modern OS. In this post, I will walk you through optimizing another key piece of your infrastructure – storage.
In my first post about IT Optimization, I likened IT infrastructure to a car. Let’s talk about trunk space for a second. Imagine that you are going camping with a couple of friends. You need a car with enough trunk space to fit all your gear, tents and backpacks. In this situation, you would do one of three things – own, rent or borrow an SUV. Owning an SUV for the sake of the occasional camping trip is expensive; a rental or borrowed car won’t have the same ease of driving as your own car. Now, what if you had a sedan, that could magically transform into an SUV, only when you needed it? Seems like a dream, right?
We are pleased to announce the Beta 3 release of Red Hat Virtualization 4.2, the latest version of our Red Hat Virtualization platform. This follows the release of the Beta 2 on February 16 of this year, as we push closer to the public release of Red Hat Virtualization 4.2 in May.
In my last post, I walked you through my quest of understanding IT optimization and why there is a need to pursue it. I also hinted at how Red Hat products and solutions can help you both optimize and innovate. Before we dive into the specifics of optimization, let’s start where we left off last time–infrastructure. Now, there are a lot of different ways to slice and dice your It infrastructure, but, it’s elementary, my dear Watson (I guess that makes me the ITO Sherlock)! The first slice is the platform, which is the foundation of your entire infrastructure. The second is the storage, which hosts all your data and applications. The final slice is the deployment footprint of choice, which determines how your infrastructure is utilized and managed. In this post, I will talk about the foundational piece, which is the platform, and how Red Hat Enterprise Linux can help you modernize your platform.
With Red Hat Enterprise Linux (RHEL), it’s now possible to configure and deploy a capacity-optimized NFS server – shared storage that costs less and stores more. Using the new Virtual Data Optimizer (VDO) module introduced in Red Hat Enterprise Linux 7.5, you can provide shared optimized storage for backups, virtual desktops, virtual servers, and for containers.
This post demonstrates how to create an advanced Network Attached Storage server that provides advanced capacity optimization services by combining VDO with many of the existing Red Hat features such as thin provisioning and snapshot capabilities. Combined with the high performance NFS server implementation provided by Red Hat, you get a powerful solution that can be deployed on-premises or in the cloud. For this example I’m using an industry-standard server with 10Gb Ethernet connectivity and SSD storage. In later articles I’ll use the NFS server to store various types of data and look at the results in terms of efficiency and performance.
How many times have you had to staff the server room during the graveyard shift just to enter a password to unlock encrypted disks at boot time? Has this requirement kept you away from securing your data? What are your options?
In Red Hat Enterprise Linux 7.5, we’ve introduced virtual data optimizer (VDO). VDO allows you to save disk space and reduce replication bandwidth with the help of data compression and data deduplication.
In this blog post I want to walk you through how you can use the cockpit Web admin console that comes with Red Hat Enterprise Linux, to set up VDO and save substantial amount of space for your virtual machine images.
New to Red Hat Enterprise Linux 7.5, Virtual Data Optimizer (VDO) is a device mapper module which adds data reduction capabilities to the Linux block storage stack. VDO uses inline compression and data deduplication techniques to transparently shrink data as it is being written to storage media.
VDO combines three techniques — zero-block elimination, data deduplication, and data compression — to reduce data footprint. The first of these, zero-block elimination, works by eliminating blocks of data consisting entirely of zeros while the second technique, data deduplication, eliminates identical copies of blocks of data that have already been stored. Finally, data compression is applied, which reduces the size of the unique blocks of data stored. By utilizing these techniques, VDO can dramatically increase
With Red Hat Enterprise Linux 7.5.0 released this week, we wanted to take a look at a few of the container-specific changes for users of Red Hat Enterprise Linux and Red Hat Enterprise Linux Atomic Host.
Buildah Now Fully Supported
With Red Hat Enterprise Linux 7.5, we now fully support using Buildah to create Docker and OCI-compliant container images. Buildah was introduced in 7.4.3 as a tech preview, and moves to fully supported in this release.
