Infraestruturas eficientes de Energia para Datacenters

White Paper conjunto da Fujitsu Siemens Computers e Knürr

"As necessidades de operação de Datacenters inexoravelmente estão crescendo mundialmente e atingiram dimensões que mesmo comparado a outros setores da indústria não pode mais ser posto de lado. Esse crescimento constante precisa de um suporte de TI em processos de negócios já existentes e os novos estão deixando os números de servidores e sistemas de armazenagem nas operações mundiais cada vez maiores.
A questão do CO2 associada a esse crescimento está focando o interesse do publico em operadores de Datacenters. Devido ao crescimento continuo nos preços de energia, essa esta se tornando um fator de alto custo nos cálculos internos. Entretanto, o aspecto principal para muitas companhias é o fato de que muitos Datacenters são incapazes de lidar com a necessidade de espaço, energia e ar condicionando da nova geração de equipamentos de TI. A não ser que alguns conceitos apropriados sejam adotados, os Datacenters podem comprometer a expansão dos negócios. Por exemplo, nos últimos anos a carga de calor nos Datacenters e em departamentos de servidores cresceu tanto que os níveis de ar condicionado nessas salas não funcionam mais."

WhoCrashed reveals the drivers responsible for crashing your computer

"Whenever a computer running Windows suddenly reboots without displaying any notice or blue screen of death, the first thing that is often thought about is a hardware failure. In reality, most crashes are caused by malfunctioning device drivers and kernel modules. In case of a kernel error, most computers running Windows do not show a blue screen unless they are configured to do so. Instead these systems suddenly reboot without any notice. WhoCrashed shows the drivers which have been crashing your computer with a single click. In most cases it can pinpoint the offending drivers which have been causing misery on your computer system in the past. It does post-mortem crashdump analysis and presents all gathered information in a comprehensible way. Normally, debugging skills and a set of debugging tools are required to do post-mortem crash dump analysis. By using this utility you do not need any debugging skills to be able to find out what drivers are causing trouble to your computer."

How Does iSCSI Work?

"iSCSI utilizes existing Ethernet infrastructure to run a modified version of the SCSI protocol over TCP/IP. Source: Adaptec I already outlined the basics of iSCSI: An iSCSI initiator connects to an iSCSI target, which eventually results in a new drive becoming available on the initiator’s host machine. The beauty of this is the way the new storage partition can be accessed: it appears as if it were locally installed in the host machine, although the iSCSI target can be located anywhere within your network. The only real limitation is network performance, which means that you shouldn’t use anything slower than Gigabit Ethernet - though a simple wireless network is technically capable of hosting an iSCSI deployment."

PerfectDisk Free Defrag


"Talk is cheap but bytes are cheaper: speed is the need with multiterabyte hard disks. It's too easy to leave high-capacity disks badly fragmented, robbing your system of critical performance advantages. There's one type of storage that delivers on speed, but at a high cost (as in money): SSDs (solid-state drives) don't use disks and should never be defragmented. But SSDs can be optimized, with care. PerfectDisk Free Defrag is a powerful disk defragmentation utility that can tell SSDs from HDDs. Its unique SSD Optimize feature consolidates the free space on SSDs with minimal impact, extending their useful life in your system."

Pokki: App Store for Windows 7


"Pokki,  not to be confused with those delectable Japanese snacks, is a compact HTML5-based framework that allows users to view commonly used Web APIs in a pop-up shell.
As Web 2.0 continues to gain traction, companies are pursuing new ways to bridge the gap between the web app and the native desktop application. Sweet Labs has recognized that as simple and sleek these Web apps may be, many users still hold a strong bond with their desktop environment to run their applications. Many developers have already attempted to make the two worlds play friendlier, such as Seesmic, Adobe, and Mozilla. Sweet Labs, however, seems to be on the right track from an integrative and design standpoint."
