IBM and Compaq yesterday announced dual-processor servers. IBM's servers have so-called self-healing and self-protecting tools, while Compaq's models have higher levels of memory availability.
Compaq introduced the ProLiant DL380 and ML370 servers, incorporating for the first time Compaq's Advanced Memory Protection Architecture. The new servers will feature Online Redundant Spare Memory, which will provide enterprises and service providers with higher levels of server uptime in cases of memory bank failures.
Compaq said the new ProLiant DL380 is the only 2U (3.5 in. thick) server to offer the redundant Hot Plug features and enterprise manageability for mission-critical applications. Compaq said the ProLiant ML370 is the first two-way server with the advanced memory protection and high availability features needed for remote site and data center environments. The new servers and their prices will be released next month.
Compaq also unveiled new TaskSmart appliance servers, the next generation C-series for accelerated content delivery and the new W-series for Web hosting.
IBM showcased two new server systems: the xSeries 232, which is a low-cost system powered by Intel's new Tualatin Pentium III-S processors with 512KB and a speed of 1.13GHz. In a statement, IBM said the x232 is able to perform a wide variety of business applications including financial, file-and-print serving, e-mail, messaging and Internet access. IBM said the 3U (5.25-in. thick) rack-mountable x342 servers, also powered by the Pentium III-S, are designed for medium and larger enterprises that need high availability features.
Both the 232 and 342 servers feature software rejuvenation, a component of IBM Director, which identifies and predicts pending software problems due to "aging," a major issued related to Intel servers, IBM said. During the aging process, small programming errors may accumulate and absorb increasing amounts of a computer's resources, eventually leading to server downtime. Software rejuvenation enables a system to automatically schedule a time to reset -- or rejuvenate -- its software, rather than allow the software to continue aging and potentially crash the server.
Software rejuvenation is part of IBM's Project eLiza, a recently announced initiative aimed at creating self-managing servers that require little human supervision, IBM said.
