Virtualization Technology for data center VSE

At present, enterprise Data center is becoming more and more popular, enterprise business application is more and more complex, it has posed serious challenge to the traditional resource fixed allocation mode of IT infrastructure. It has become increasingly clear that the crux of many IT systems built on traditional models is not the lack of performance but the ability to adapt to change. As the industry's first deliverable (product) fully implemented server virtualization product, HP VSE (Virtual server environment, VM environment) in many data centers, the practical application shows that virtualization technology can centralize and share resources, achieve cost reduction, The purpose of optimizing utilization. At present, HP VSE is getting large-scale popularization application.

Virtualization: Data Center required weapons

In recent years, virtualization is becoming a key technology for a new generation of data centers. This is because many companies have grown very fast in the late 90, so it has deployed a separate server for each business application, leading to the fact that most of the company's data centers are a server ocean, most of them underutilized. Taking a bank as an example, IT systems are distributed across many operating systems such as Sun Solaris, IBM AIX, Windows2000, WindowsNT, UnixWare, Windows2003, and system management and provisioning are complex and pose many problems. To this end, they are eager to consolidate so many systems, and hope that the integrated system can support UNIX, Windows and Linux operating systems, and has the ability to partition processing and security and reliable performance, but also a strong scalability. Finally, the bank used HP Superdome high-end server and VSE software package to successfully upgrade the original data center, according to the future application system planning, the bank has redesigned the new data center it architecture, through two high-end servers to complete the existing many systems integration, The resource allocation and unified resource management based on service level goal are realized. The completion of the new data center not only reduces the complexity of the system management, improves the management efficiency of the enterprise, reduces the management cost, but also provides a reliable guarantee for the reliable operation of the banking production system and strengthens the core competitiveness of the enterprise.

In the above case, the key technology is the virtualization solution provided by HP's VSE (Virtual server environment). It should be said that server virtual technology is not a new concept. On the concept of virtualization, vendors have their own different definitions, the core idea, however, is that it is a way to simplify management and efficiency by differentiating resource priorities and allocating IT system resources wherever and whenever they are most needed, thereby reducing the resources that are reserved for a single workload peak. Virtualization can effectively reduce the number of servers to increase speed, simplify server management, while significantly improving server utilization, network flexibility and reliability. With the use of virtualization technology, users will likely consolidate multiple applications to a small number of enterprise servers and remain highly reliable and flexible, thereby enhancing the ability of IT systems to adapt to business changes.

HP VSE: The leader of virtualization

HP takes the lead in the delivery of server virtualization products. HP uses a set of deliverables, products, and full server virtualization products--HP VSE products to the competitors far behind. Overall, VSE is an integrated virtualization solution on a multiple operating system platform that enables IT organizations to configure one or more server environments as reusable pools of resources, centralize resource management and sharing, increase resource utilization efficiencies, and automate provisioning to meet the growing and changing business needs of the enterprise, Achieve full synchronization of it and business development.

With a careful look at this product, the advantage of HP VSE is that it provides the richest and broadest range of partitioning technologies, includes 4 very complete partitioning methods, such as hardware partitions, virtual partitions, virtual machines, and resource partitions, which can also be superimposed, which is used when multiple partitions are deployed on a single server. can provide a better combination of isolation and flexibility. VSE supports multiple operating systems and is very practical in today's complex multi-platform enterprise IT applications. And, VSE has a suite of integrated management tools that covers the main management functions of the data center. It also provides a public price scheme (Utility Pricing), which enables users to obtain pre-configured hardware at any later time, as needed.

At present, many manufacturers are committed to the research of virtualization technology, but most manufacturers are still trying to solve the most low-level parts virtualization challenges and committed to the implementation of the exclusive system strategy, but HP (HP) has entered the next step, already can provide users with a series of high-level integration, Virtualization solutions for multiple operating systems and, together with partners, provide more than 250,000 virtualization solution licenses for the marketplace.

Four zoning technology unrivaled industry

The core of HP VSE virtualization technology is the unrivaled industry's 4 different partitioning technologies. The hardware partition (Npar,npartitions) is unique in the industry because it provides a fully electrically isolated partition within a single system. This is done by using a custom chipset design in each cell board, which configures the firewall to ensure that the electronic signals that are not part of the partition board are discarded, ensuring that hardware failures in one partition do not affect all other partitions on the system. On top of different hardware partitions, you can have a completely different operating system, for example, in the same server, you can run the HP-UX, Windows, OpenVMS, and Linux four completely different operating systems. In addition, for each load, the main advantage of hardware partitioning on a separate server is that it can resize hardware partitions extremely quickly.

A virtual partition (Vpar,virtual partitions) is the ability to run multiple HP-UX operating system copies on a single core hardware group. It can be a separate server or within a hardware partition. The main feature is that software partitions can run multiple operating systems in a single hardware partition or a separate partition, providing smaller granularity. A CPU, an I/O card can be combined into a virtual partition to become a UNIX operating system. They can be individually started and turned off separately, and can dynamically adjust CPU resources between different virtual partitions. They are still a relatively very independent environment that provides different patch levels between these different operating systems and provides different parameters to best meet the needs of these applications.

The Integrity VM (virtual Machine, VM) is a new partitioning technology designed specifically for the Integrity platform, and it is also a virtual partition in which the system hardware itself is completely virtualized. The result is that the operating system can run within the VM without modification. This means that users can run any operating system that supports the integrity platform within the VM. You can also define specific CPU allocations for each VM. For example, you can assign 50% to 4 physical CPUs for a four-CPU VM, 25% for another, and 10% for the third. The Integrity VM provides fully virtualized I/O, meaning that a single physical SCSI card or Fibre Channel card can be virtualized into multiple SCSI cards.

The security resource partition (Srp,secure Resource partitions) is a set of technologies that have been implemented in the HP-UX kernel. This product puts all of these features into process resource management (processes Resource manager). PRM provides a single configuration interface, so users can define partitions, allocate CPU, memory, disk I/O, and security rules, and then assign an application or a group of users to run in that partition.

HP has the absolute leading edge in it virtualization, is the only enterprise in the world that can provide three levels of virtualization solutions, such as parts, integration and full virtualization, and the only vendor that can integrate the goal-based automated workload management (WLM) and a range of high-availability features in a virtual server environment.
