Das Rechenzentrum steht, als eines der maßgeblichen Bereiche innerhalb der physikalischen IT-Infrastruktur, sowohl für die Herausforderung, Unternehmen dabei zu unterstützen, ihre strategischen Ziele zu erreichen, als auch für die Möglichkeiten, die anstehenden organisatorischen Veränderungen der Arbeitsabläufe zu realisieren.
In einer digitalen Welt, für die das “jederzeit”, “überall” und “mit jedem Gerät” gilt, sind Unternehmen kontinuierlich mit der komplexen Herausforderung konfrontiert, immer mehr Informationen, Daten und Applikationen für immer mehr und zunehmend mobilere Anwender an immer mehr Endpunkten bereitzustellen. Unternehmensanwendungen sowie die ihnen zugrunde liegenden WANs (Wide Area Networks) werden so zur maßgeblichen Basis
MySQL, the most popular open source database in the world, is frequently used to support Web 2.0 applications and cloud deployments. Scaling MySQL can be a challenge when workload demand starts to strain the database. One option is to scale up by upgrading to a more powerful server, which works well to a certain point
Today’s IT departments are faced with ever increasing demands on their applications as the number of users and underlying databases continue to expand. Application performance has not been able to keep up with this exponential growth. The first thing an IT organization tries to do when performance drops is to add incremental CPU and memory
Increasing the I/O performance of next-generation data centers and cloud computing environments is essential for supporting enterprise e-commerce, database, and email applications. To successfully deploy high-performance storage, it is essential for storage appliance software to be flash-aware and exploit solidstate drives (SSDs) for high random I/O performance and hard disk drives (HDDs) for capacity (cost
Enterprise storage continues to demand higher performance to meet rising workload levels and higher reliability to push down total cost of ownership. At the same time, IT departments remain budget-constrained. Storage tiering provides an efficient approach to meeting these three, occasionally conflicting, goals. While buyers often discuss such factors as media technology (solid state drive
Solid-state drive (SSD) endurance is an important factor in system design. Due to characteristics of flash media, repeated write cycles eventually wear out an SSD. Solid-state drive (SSD) endurance is an important factor in system design. Due to characteristics of flash media, repeated write cycles eventually wear out an SSD. Drive replacement is more frequent
Current hard disk drive (HDD) technology is reaching the upper plateau of a technology “S” curve, constraining in the near term the ability of manufacturers to increase the storage capacity of a disk drive. Recently, the maximum capacity of HDDs has been doubling every two to three years. In contrast, a decade ago, the maximum
The SAS device interconnect and transport protocol is designed for enterprise-level performance, scalability, reliability and high availability, while SATA is optimized for lower cost and consumer applications. The SAS feature set has clear advantages for performance, scalability and availability as well as a road map in place to 24 Gb/s.
When properly structured, benchmark tests enable IT professionals to compare solid-state drives (SSDs) under test with conventional hard disk drives (HDDs) and other SSDs. To be truly useful, SSD benchmarks should show the performance of the SSD under the kinds of heavy workloads that are typically encountered in enterprise applications.In addition, the benchmark should evaluate
