Storage Virtualization refers to the process of completely abstracting logical storage from physical storage. The physical storage resources are agregated into storage pools, from which the logical storage is created. With storage virtualization, multiple independent storage devices, that may be scattered over a network, appear to be a single monolithic storage device, which can be managed centrally. Storage Virtualization is commonly used in SANs.

IT-Informatik chose a full virtualization strategy, based on IBM® PowerLinux™ servers with IBM PowerVM® virtualization and Live Partition Mobility, to manage its SAP hosting services. The new solution slashes IT operational costs by more than 50 percent and enables IT-Informatik to set up new customer environments 80 percent faster.
When rack-mounted servers first appeared on the scene in the 1990s, they offered considerable advantages over the behemoth boxes they replaced. Their small, standardized footprint went a long way toward making data centers easier to manage. In the ensuing decades, form factor size and compute power have had an inverse relationship.
Their universal standardization earned them the nickname “pizza box” servers, and it was a key driver of the scale-out computing model popular in the early 2000s. Populating a rack of eight servers and either clustering them or implementing failover from one to the other was far easier than previously possible.
Virtualization was supposed to be the disruptive technology that saved IT. The cost savings from consolidation and the ease at which applications can be deployed promised to vastly improve delivery of IT services, free up IT staff to work on other projects, and not strain budgets.
Unfortunately, lack of insight into IT resource status in highly virtualized environments and the complexity of the interactions between server, storage, and network elements have added to IT staff manual workloads and led most companies to dedicate too much time to operations and not enough time to innovation. This basically negates the major benefits of virtualization.
Every data center IT manager must constantly deal with certain practical constraints such as time, complexity, reliability, maintainability, space, compatibility, and money. The challenge is that business application demands on computing technology often don’t cooperate with these constraints.
A day is lost due to a software incompatibility introduced during an upgrade, hours are lost tracing cables to see where they go, money is spent replacing an unexpected hardware failure, and so on. Day in and day out, these sorts of interruptions burden data center productivity.
Sometimes, it’s possible to temporarily improve the situation by upgrading to newer technology. Faster network bandwidth and storage media can reduce the time it takes to make backups. Faster processors — with multiple cores and larger memory address space — make it possible to practically manage virtual machines.
This report documents the results of ESG Lab’s hands-on testing and validation of the HP 3PAR StoreServ 7000 storage array, with a focus on autonomic simplicity, efficient unified storage, application performance, and resilience for mid-range enterprises.
"Cloud computing, also known as 'IT as a Service', is predicated on delivering IT services on demand, an idea that has support from business leaders as a way to better align IT with business operations. Cloud computing has two key requirements: virtualized applications and seamless support and integration between the server, networking, storage and hypervisor components.
In this paper, we explore these concepts and highlight the critical features necessary to move beyond server virtualization by leveraging key integration capabilities between IT components-with a particular focus on the important role that storage plays in the evolution of the datacenter architecture."
As the amount of information we generate grows, and as our relationship with information grows more complex, the race to innovate new products and services to help us harness information, manage it, and tap into it more easily intensifies. This paper discusses the continuing development of HP’s strategy for delivering Converged Storage that improves the ability of your business to capitalize on information. Building on the foundation provided by fusing industry-standard technologies, federated scale-out software, and converged management, HP is now extending Converged Storage into new solutions and segments with a new initiative that introduces the next evolution of this HP Converged Storage strategy and vision.
This IDC paper “Business Value of Blade Infrastructures” indicates the considerable cost savings and the improved agility of the IT infrastructure by migrating to an HP BladeSystem environment. In fact, HP BladeSystem cut data costs by 68%. Customers participating in this study were able to pay back their initial investment in just over 7 months, a significant factor given the financial constraints most IT organizations are facing.

Flash Storage For Dummies explores the many uses and benefits of flash storage technology in the enterprise. From server cache and back-end storage cache to hybrid and all flash arrays, flash technology improves performance and increases reliability in storage infrastructures. It also reduces energy and real-estate costs in the data center.
Organizations have achieved significant benefit from virtualizing servers and storage environments, and now face the daunting task of deploying new network architectures to keep pace. Riverbed Technology and VMware have joined forces to help address these problems and make it easy to deploy and manage VXLAN overlay networks in highly virtualized data centers.

Minimizing application and service disruptions while maximizing end-user experiences are paramount goals for any organization. Businesses of all sizes are challenged with ensuring their applications perform, yet, performance management solutions that understand the full performance picture, (applications, networks, virtualization, cloud, etc.) traditionally have been focused on the needs of very large enterprises.
To remain profitable and competitive, organizations need to ensure that every resource is consumed economically and every asset utilized optimally. With fragmented operations, tools and information, many organizations are failing to collate and analyze the metrics needed to bridge the data center performance divide.
