stack (frame size, ). Oracle Database Different versions, patches and options, about hundred configuration parameters.

5 Storage Network Application Network System Management, Operations, Security, Ressource Management Benchware Ltd Complex architecture of Oracle platforms needs benchmarking Application Middleware (apps server, esb) Database System Volume & File Management Application Network (IP-based) Bandwidth, latency during remote database mirroring (sync, async) due to switches and sql*net and tcp/ip stack (frame size, ). Oracle Database Different versions, patches and options, about hundred configuration parameters. Storage Network (FC-, IB- or IP-based) Bandwidth, latency during remote storage mirroring (sync, async) due to switches, hubs and distance. Volume & File Management Different volume managers (VxVM, ASM) and file Systems (UFS, VxFS, ext3, JFS, ZFS, raw devices), different I/O methods (async, direct), a lot of config parameters (#LUNS, queue depth, max i/o unit), software striping and/or mirroring, multipathing. Server & Operating System Server & Operating System Different server Systems, processors and CPU architectures, (x86, IA-64, UltraSparc, SPARC64, Power), #cores, multithreading, main memory, bus architecture. Different operating Systems and patches, over hundred configuration parameters, virtualization of resources. Storage System Performance of complex technology stack is NOT predictable unless running a benchmark Storage System Different storage Systems, storage tiers and storage technology: spindle count and speed, RAID management, cache management, server interface technology, storage system options like remote copy, hardware striping and/or mirroring, virtualization of resources. copyright 2012 by benchware.ch slide 5
