Server Construction That Replaced Mainframes Still Effective

svrcnCorporations are moving to multiprocessor servers from two directions. Some are stepping down from outdated and expensive mainframe environments, while others are stepping up from the slightly souped-up PCs they’ve been using as file servers.

Either way, buyers seek out power, scalability and fault tolerance, though not necessarily in that order.

“Super” servers flex their multiple processors in one of two architectures. Asymmetric multiprocessing dedicates each processor to a specific task. In symmetric multiprocessing, a more advanced and costlier technology, tasks are distributed to whichever processor is available. This makes their hard drives easier to recover in general.

But some network operating systems, most notably Novell Inc.’s NetWare, do not support more than one processor. So compatibility with network operating systems is as important to super-server buyers as multiprocessing power is.

As part of its conversion from an IBM 4381 mainframe to a networked-PC …
