SuSE Enterprise Server Goes
64-Bit">SuSE Enterprise Server Goes 64-Bit At the CEBiT technology show in Hannover, Germany, SuSE on Wednesday also announced that the latest version of its advanced enterprise operating system, the 64-bit SuSE Linux Enterprise Server 7 for IBM eServer zSeries, will be available in May. Pricing is not yet available.The 64-bit version expands the possibilities of SuSE Linux Enterprise Server 7 for S/390 and zSeries. For example, complex database applications can benefit from the much larger address space and are not confined to a memory boundary of 2GB, he said. "In order to fully retain the value of investments in existing applications, the 31-bit shared libraries of SuSE Linux Enterprise Server 7 support the parallel operation of 31-bit and 64-bit applications on the same machine within the same Linux instance," Dyroff added. This latest offering is based on Version 2.4.17 of the Linux kernel and supports both S/390 servers and IBMs latest server generation, eServer zSeries z900 and eServer zSeries z800. The support of HiperSockets, a high-performance feature unique to IBMs eServer zSeries, also substantially accelerates the speed of the data transfer between virtual servers in the mainframe. The host operating system, z/OS, also supports HiperSockets, allowing data exchange between SuSE Linux and z/OS with maximum bandwidth and near-zero latency, he said. "SuSE Linux Enterprise Server 7 for zSeries also supports the journaling file system ReiserFS," Dyroff said. "Data entities containing large numbers of small files especially benefit from the efficiency and performance of ReiserFS. "The network and disk device configuration can be modified dynamically without a reboot, while the Logical Volume Manager allows the run-time integration of dynamically attached storage devices into existing virtual volumes of almost arbitrary size, while delivering practically unlimited disk space without downtime."
"This offering now completes our product offerings for the IBM server line. IBM mainframes are the ideal solution for running mission-critical applications such as the administration of complex e-business transactions and enterprise resource planning systems," Dyroff said.
