Several years ago, Verizon Data Services rethought its availability strategy, making it a part of the company's operating culture. A redesign of its strategy focused not only on systems and platforms, but involved a combination of a high-performance infrastructure, continuous data accessibility and protection from data loss.
GDPS provides all of the benefits of a Parallel Sysplex, while enhancing an enterprise's disaster recovery abilities and managing planned exception conditions. GDPS allows a business to achieve its own continuous availability and disaster recovery goals.
Availability managment is a proactive approach to systems management that identifies and responds to systems events -- before they cause larger problems or even a systems failure. Availability is maximized by continually monitoring system components, identifying events likely to occur and taking preventive action.
As companies continue to generate vast quantities of data, they must have compact, inexpensive ways to store the information they need to do business. Efficiency and cost control are at the heart of virtual tape technology. Recent software-based, hardware-independent advances in virtual tape technology enable storage managers to create a virtual tape environment from any combination of OS/390 disk and tape hardware - including resources the organization already owns.
Today, most mainframe installations are increasingly interested in TCP/IP implementation and connnecting the intranet and Internet to their enterprise systems to access their legacy data and applicatios. This is where the Netfinity ESCON Adapter offers capabilities not found in other channel-attach products, TCP/IP Direct Connect and the Multi-Path Channel (MPC+) drivers.
With the evolution of network management, more responsibility has been placed upon the "framework" to fulfill the TMN FCAPS model. Typical network operations centers, which support Simple Network Management Protocol (SNMP)-based logical and physical devices, must now be capable of supporting all business units in a uniform fashion.
Java development efforts are sweeping through the enterprise. Existing legacy applications are being reengineered to include Web front-ends. E-business is an idea whose time has come. This article introduces an Object-Oriented Project Size Estimation technique that can help predict the amount of time it takes to design, code and test an object-oriented project.
New mission-critical e-business applications must be developed more rapidly, meet higher quality standards, and be updated quicker than ever before. This demand for speed is captured in the now familiar terms "Internet time" or "e-time."
The SIAC now identifies exact operational functions of the COBOL programs running in its S/390 environment. Using InCert Examiner, SIAC gains the understanding needed to test the "right stuff" and eliminate the uncertainty of guesswork.
Public monorails and hovercrafts may be a thing of the future, but for data moving and sharing, the future is now. Fibre channel has blazed its way to the top of next-level networking technologies.
Database marketing firm Acxiom Corporation relies on SyncSort Inc.'s PipeSort to help slash the company's MVS elapsed time by 40 percent.
In the chicken-and-egg world of vendor marketing and user need, clustering has achieved "hot topic" status. Depending on individual needs, a variety of vendors manufacture appliances to target specific points of failure. To be effective, however, the solutions you choose must provide simultaneous coverage for multiple points of failure.
A counter view of today's Fibre Channel frenzy.
The driving force behind implementing centralized management systems is their cost-effective management of networked systems. For most IT organizations, centralized management systems are the only way of approaching the same level of reliabilty, availability and control that has been available with mainframe environments of the past.
Whether you choose Data Link Switching or Enterprise Extender, adopting an SNA over IP solution offers you the chance to pump up your e-business strategy, reduce the costs of your IT department and increase the profits of your business units.
High availability and disaster recovery are two mutually exclusive categories with one architecture. The challenge is to first understand what you need, and find the architecture that best fills those needs.
By choosing reliable products, addressing people issues and implementing processes that reflect the best practices, businesses can get the high levels of availability they need to remain competitive.
The rocky terrain of recovery is difficult to navigate. Determining the time it takes to drive through the recovery process and identifying alternate routes can help make your ride a little smoother.
Service Level Agreements (SLAs) can by maintained by building a well-designed network that integrates multiple protocols and services over an IP infrastructure. Network managers must use tools that are designed for a multi-protocol, integrated services environment to establish accurate response times and to maintain SLAs.
