Today, the typical mainframe
storage administrator manages on the average more than 40 terabytes of disk storage while the typical storage manager for Unix, Linux and Windows manages from 1 to 5 terabytes.
Launched in 2002, Corigin is a global provider of breakthrough mainframe
data access software solutions that deliver cost-savings, availability, and productivity.
For example, a recent ITG study determined that within a mainframe
environment, the average cost-per-user on an annual basis is approximately $2,300 versus nearly $6,500 for PCs in a local area network environment.
CICS: This widely installed mainframe
product, which enables workstations to perform online transaction processing, as well as management of controller and device networks, has been extended to clients (PCs and workstations), as well as Hewlett-Packard processors.
Therefore, data transfers between mainframe
and open systems processors can potentially take one of three forms:
Tying its mainframe
operating systems to its mainframe
computers by conditioning sales of its operating systems on the purchase or continued use of only those IBM-compatible mainframe
computers that are manufactured by IBM;
storage devices are more expensive than their open systems cousins.
Automated AQM will become increasingly important especially where the mainframe
supports WebSphere and DB2.
Automated Features--With more than 20 autonomic features, the new system allows mainframe
jobs to execute in parallel and queue management is moved to the ESS from the server.
Although SABRE Computer Services is a proponent of distributed computing, it carefully evaluates the pros and cons of any conversion projects that require substantial rewriting of existing mainframe
The Channel Gateway 3400 streams data directly from native mainframe
FICON and ESCON channels to FC-based tape drives and libraries.
As organizations increasingly realize that they need to re-use rather than replace their existing mainframe
applications, any initiative that enables them to do this at lower cost and risk is extremely valuable to them," said Gary Barnett, IT Research Director at OVUM.
