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.
Selecting the right virtual-aware anti-malware solution is more important now than ever. Read this white paper to learn the risks associated with virtualization, and the options available for your security needs.
In this Research Report, Clabby Analytics takes a closer look at IBM’s Flex System converged architecture. The new Flex System’s advanced blade offering shines compared to its closest rival: traditional blade architecture. Flex System offers superior manageability, faster communications, more storage capacity (using up to eight internal solid state drives [SSDs] per compute node) and better storage management — as well as broader/better physical/virtual system management — than all of today’s leading blade competitors.
Cloud adoption is an evolutionary process that has been leading to hybrid clouds—specifically, open hybrid clouds that provide for portability of applications and data. This new model means avoiding new points of proprietary lock-in and new silos, and breaking from proprietary software and hardware.
Faced with trends like cloud and the rapid rise of mobile devices, IT needs a new, simpler model of building networks to support and optimize applications. In this Lippis Report, learn how the Cisco ISR Application Experience Router helps you improve application speed, security, and control.

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.
"As any technology becomes increasingly popular and widespread, certain pieces of inaccurate information begin to sound like facts. Moreover, as a product matures, it evolves by taking on new features, shedding old ones and improving functionality. However, many products continue to carry those myths as truisms even as the version count rises higher. Get the facts about vSphere.

"IOPS (I/O operations per second) is an easily understood and communicated unit of measurement, which is why it’s so widely used. Unfortunately, it’s also easy to oversimplify. IOPS describes only the number of times an application, OS or VM is reading or writing to storage each second. More IOPS means more disk I/O, and if all IOPS are created equal, we should be able to measure disk activity with it alone. But they aren’t.

"The number of vCPUs should be one of your most important considerations when sizing virtual machines. But getting the right balance — neither over-allocating nor under-allocating — is a challenge. You’ll need to select the number of vCPUs, the size of the virtual disk, the number of vNICs and the amount of memory. With all those variables, a little guidance is in order.

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.
