If you have been thinking that software-defined storage (SDS) can only be used in an OpenStack environment, think again. Storage for OpenStack only represents a tiny fraction of the multi-billion dollar enterprise and cloud storage market. Just about any industry, government, defense, satellite imagery, medical imagery, media and more has incredibly large storage needs that are growing exponentially every year.
Before the arrival of SDS, the only choice organizations had was to invest in expensive storage appliances, and to keep investing in more and more of them whenever they needed to accommodate exploding data storage needs.

Increasingly in today’s world, data centers are moving towards software-defined computing, networking, and storage. IT infrastructure that supports the application and data workloads is moving from bare metal servers to cloud. While the most obvious justification for this shift can be summarized as increased efficiency, capacity utilization, and flexibility (to scale up or down), there are less obvious fundamental economic and financial principles in play that contribute to overall business stability of the organizations and lines of business (LOB).
Cloud computing has changed the cost structure of IT infrastructure. Historically, IT infrastructure was considered a capital expenditure (CapEx) that requires large upfront investments leading to higher fixed costs for the business. With the advent of cloud computing, primarily because of its pay-for-use billing model, IT expenditure shifted from fixed operating cost structure to variable operating cost (OpEx) model.
This shift not only decreases the need for larger cash flow requirements or, in lieu, higher liabilities on balance sheet (akin to capitalization of lease expenses) for the CapEx, it also reduces the volatility in the operating income for the business.

Cloud computing represents a major shift in enterprise IT architecture that requires companies to rethink their strategy. Red Hat is bringing to market a full portfolio of training and certification offerings that enable customers to evaluate Red Hat’s cloud technologies and understand how to deploy them successfully.
Customers seeking to build an open Infrastructure-as-a-Service (IaaS) cloud may look to Red Hat OpenStack as their foundation. OpenStack is emerging as a leading platform for IaaS cloud architectures and has attained broad industry support. Red Hat is excited to announce the immediate availability of Red Hat OpenStack Administration (CL210), which provides architects and system administrators with a hands-on course to learn how to install, configure, and manage a Red Hat OpenStack deployment. Later this summer Red Hat will also introduce the Red Hat certificate of expertise in OpenStack IaaS, which will validate a professional’s ability to successfully deploy and administrate an OpenStack based IaaS cloud.
For customers looking to deliver an open Platform-as-a-Service (PaaS) cloud, OpenShift Enterprise by Red Hat may be the solution. OpenShift gives application developers self-service access so they can easily deploy applications on demand. Red Hat is pleased to announce the immediate availability of OpenShift Enterprise Administration (CL280), a heavily lab-based 2-day course that guides the student through the steps to install, configure and manage an OpenShift based PaaS cloud.

Replicated Red Hat Storage Server Volumes provide you with high-availability, when a single server goes down all your data is still there. Even better, if you were using that server to access your data using the native client it will automatically switch over to a server that is still responding. But what if you want to mount the volume while the server you normally use is down?
When you want to mount a Red Hat Storage Server Volume from your /etc/fstab you normally use a line like this:

Cloud is not software, cloud is not hardware, cloud is not virtualization, and cloud is certainly not a panacea for broken IT. Cloud is an architecture: a set of fundamental tenets that have different implications at different levels of IT, from network, to hardware, to applications, and to the IT process itself. To say you have a cloud is to say that you have a cohesive architecture, technology set, and most importantly processes, that work towards a defined goal under a set of well-understood principals. Building your cloud is as much about defining your goals and governing principals as it is about investing in technology.
Building your cloud and consuming cloud services
Step one is defining your governing principals. This is a crucial step before embarking on your cloud journey as the policies and principals you define will help you navigate your journey through the rapidly expanding cloud ecosystem. This is also an opportunity to ask tough questions and examine what your principals and processes are, and why you have them. Process is ultimately about managing risk, so consider what risks are acceptable under your governance policies and weigh them against the potential benefits cloud can offer. Both Facebook and Google have adopted “deploy to production” models that seem to fly in the face of process conventions such as ITIL or RUP, yet somehow they seem to survive. The penalty for not doing this exercise is ballooning adoption costs, or failed rollouts all together.

With the release of the updated Red Hat Enterprise Clustering and Storage Management Course (RH436) for Red Hat Enterprise Linux 6 a couple of new subjects have been introduced, while others have been updated to reflect the changes in the Red Hat High-Availability Add-On moving from Red Hat Enterprise Linux 5 to Red Hat Enterprise Linux 6.
One of the most noticeable new subjects in this updated course is the inclusion of an introduction to highly available, distributed, scalable storage using Red Hat Storage Server. Other updates include the use of multipathed storage throughout the course, as well as coverage of the XFS® file system.
