Creating the IT infrastructure, consumers increasingly prefer the so-called "cloud architecture, which can not only reduce costs for hardware and IT maintenance for continuous operation, but also to improve basic infrastructure meet business requirements. The first operating system for cloud computing, VMWare vSphere 4 provides integration and holistic management of an extensive set of infrastructure elements - compute resources, storage devices and data, as well as optimal performance of existing enterprise applications and next-generation applications.
For service providers hosting VMware vSphere 4 provides a more economical and rational opportunity to become suppliers of "cloud" services that are compatible with the internal data center customers.
VMware vSphere: Efficiency. Control. Select.
VMware vSphere 4 continues the three pillars of the previous generation platform VMware - VMware Infrastructure 3: efficiency and performance to run business-critical applications, control over the level of the application, selection of client hardware and operating systems, as well as ways to launch applications.
Efficiency. One of the main reasons for choosing client cloud computing - cost reduction for IT services and the release of the budget for new projects and initiatives. VMware vSphere reduces capital and operating costs at times greater than the previous generation of VMware Infrastructure 3. In addition, VMware vSphere provides a 30% increase in e level of consolidation, up to 50% savings in storage at the expense of VMware vStorage Thin Provisioning and up to 20% savings on power and cooling due to Distributed Power Management, which uses VMotion, for the automatic placement of virtual machines at the least possible number of physical servers without disruption of business applications.
Performance and versatility for a fully virtualized IT infrastructure - a "private cloud" over the previous generation, VMware Infrastructure 3, VMware vSphere demonstrates a significant increase in performance and versatility and makes it possible to run a "private clouds," even the most demanding applications, such as, for example, extensive databases, Microsoft Exchange, and so on.
VMware vSphere offers more powerful virtual machine:
2 times more virtual processors per virtual machine (from 4 to 8)
In 2,5 times more virtual NIC to a virtual machine (from 4 to 10)
4 times more memory in a virtual machine (with 64 GB to 255GB)
3 times more network bandwidth (9 Gb / s to 30 Gb / s)
3 times as much restriction on the number of I / O operations per second (up to 300, 000)
A new record for the number of transactions per second - 8900, which is 5 times more traffic in the network of international payment system VISA worldwide
Improved performance for specific applications:
Up to 50% performance increase for the workload on application development
Up to 30% increase in productivity for Citrix XenApp
VMware vSphere makes it possible to consolidate more virtual machines and hardware resources into a single logical resource, or "enterprise computing" to create a "universal computing machine of the 21 st century. vSphere can arrange together to:
32 physical servers with the number of processor cores by 2048
1280 VMs
32 TB RAM
16 petabytes of disk space
8000 network ports
Control. vSphere ensure effective operational control over these high-performance "computing companies" with the new large-scale management features such as VMware Host Profiles and VMware vNetwork Distributed Switch to standardize the configuration of the server, which increases the overall security, network configuration storage and transmission, automation of configuration management and reduce errors related to improper configuration. For the medium to 100 virtualized hosts, these new management capabilities can save about 25 weeks or six months of working time system administrator, thus significantly reducing operating costs.
VMware vSphere provides uncompromising control over the level of service for applications to ensure the necessary levels of efficiency, safety and versatility for all applications regardless of operating system or application architecture.
No downtime and data loss - protection against system crashes with VMware Fault Tolerance, without the cost and complexity of alternative products.
Minimize planned downtime due to SAN technology VMware Storage VMotion for the live migration of virtual machine file, which is now available with the new interface
Fast, easy and cost-effective backup for all applications with VMware Data Recovery.
Simply providing more precise safety standards with VMware vShield Zones by implementing corporate security policies at the application level in the logical zones in the general environment and to maintain the reliability and network segmentation of users and data.
Select. With VMware vSphere 4 customers receive the freedom of choice, while remaining independent from the hardware, operating system, applications and service providers. For example, vSphere offers the widest range of guest operating systems.
