datacenter

La verdad ni me enteré hasta hoy que lei el correo electrónico que me envio mi proveedor de hosting (elenlace.com). Pues resulta que decenas de miles de sitios web se encuentran inoperativos por una falla eléctrica que se produjo ayer en la tarde en uno de los datacenters más grandes de los EEUU, el H1 de [...]

I have received a couple of e-mails about the Datacenter Physical Security Blueprint with comments that my blueprint is too movie-like, and that it is way too costly to implement.So i did a little shopping around, and i requested budget prices for every element of my Blueprint (budget prices are usually higher then purchase prices, since they are a non-obligating quotes for budget estimation).Here is the math. All prices are in US dollarsSecurity equipment9 CCTV cameras with infrared sensors - 130$ a piece = 1,170$8 Glass break sensors - 45$ a piece = 360$8 Motion Sensors - 30$ a piece = 240$4 KeyCard readers (with combined electronic/mechanical lock and open/closed status sensor) - 150$ a piece = 600$2 KeyCard readers with Keypad (with combined electronic/mechanical lock and open/closed s

A very important aspect of Information Security is physical security. A significant amount of security incidents are found to be performed utilizing some vulnerability of the physical security.So, here is a set of rules to create a blueprint of physical security of a IT department and data center for a company. The system room must not have windows. Ideally, it should be in the center of the building.All equipment that is not used must be stored in dedicated storage space, away from production environmentAll high security spaces should be monitored by CCTV cameras.Access control zones must be implemented, to create a security barrier as well as provide a log of access activities. These are created by doors opened by electronic key cards or multiple-factor authentication.All windows should

Google es sin duda una de las empresas que más infraestructura web ha desplegado, hasta tal punto que cuando dejo de anunciar sus webservers como "Apache", pues en realidad es una versión modificada del mismo y comezó ha usar como identificación de los mismos "gws" (abreviatura para Google Web Server), la diferencia entre Apache e [...]

Ogni tanto fuoriesce qualche notizia sui datacenter che i vari Google, Microsoft & c. stanno costruendo in giro per il mondo.L'ultima notizia (qui sul blog di Carr) è di Microsoft, che sta costruendo un datacenter in a Irkutsk in Sibera; l'impianto costerà circa $500 milioni di dollari e conterrà decine di migliaia di server.Dopo il datacenter di Google in Oregon costruito vicino al fiume Columbia per raffreddare i server ad acqua, Microsoft ha scelto la fredda Sibera per risparmiare sul condizionamento.Max

Hackers in Turkey have attacked more than 5,000 Swedish Web sites in the past week, and at least some of the sabotage appears linked to a Swedish newspaper’s publication of a disparaging caricature of Islam’s prophet, an Internet company and a media watchdog said Sunday. Around 1,600 Web sites hosted by server-provider Proinet and 3,800 sites [...]

El governador de Iowa Chet Culver y Google Inc. anuncian planes para abrir un datacenter en Council Bluffs por 600 millones de dólares. El centro contará con 200 empleados y tendrá casi 223,000 metros cuadrados. Los trabajos creados por este centro mantendrán operaciones 24 horas al día, por todo el año, con un enfásis en administración de Linux, asistentes y managers. El total de salarios rondará como 10 millones de dólares al año. Google también ha puesto énfasis en la contrata local de suministradores al mismo tiempo que se aprovecha de un mejor nivel de impuestos y suministro de energía más barato. Compártelo

Sun proudly claimed it had solved all potential server problems when it shipped its project BlackBox server in a shipping container. But it left out an obvious California challenge: earthquakes. So Sun shipped off one of the devices to a testing facility where it was subjected to some of the worst trembles that have been known to hit the golden state. Sun put it to test by exposing a container full of server racks to the force and motion of the epicenter at a 6.7-magnitude earthquake and keeps working just fine.The earthquake was simulated using a six-degrees-of-freedom hydraulic platform and data collected at Northridge, CA on January 17, 1994. Everything was up and running and the only cause of failure was caused by 'power cords coming out'.via gizmodo

Organizations are increasingly evaluating and implementing liquid cooling solutions to meet the heat challenges of blade servers and high-density computing. Liquid cooling solutions utilize air/liquid heat exchangers to provide quiet, uniform, effective cooling.Many IT professionals list cooling as a top issue in data center management, as excess heat and high temperatures can shorten equipment lifespan, cause system downtime, and negatively affect equipment performance. As organizations add blade servers to their IT infrastructure, server rooms and datacenters demand more electricity and produce more heat, with some high-density racks exceeding 30 kW and some experts estimating up to 50 kW per server rack, within the next five years.

SEATTLE (Reuters) - Microsoft Corp. ha construido una granja de servidores y de sistemas de almacenaje de datos que servirán como la espina dorsal del esfuerzo de Microsoft de combatir la extensión en la Web de Google Inc. y de otras empresas. El nuevo centro de datos de Microsoft en Quincy, Washington, es su "granja más grande de servidores" hasta la fecha y una manifestación física de las grandes ambiciones de la compañía para ser una fuerza activa en el mundo de los servicios del Web. Los diez mil servidores que consta esta granja se encenderan el 16 de abril y Microsoft ya está en el trabajo sobre otro centro de datos masivo con una inversión de $550 millones en San Antonio, Tejas. Esas instalaciones son de los primeros centros de datos que van abrir desde que Microsoft sorprendió a los inversores el año pasado con un plan agresivo para intentar hacerse con los servicios de la web. Los "centros de datos son una infraestructura básica que permiten los servicio

Heat is an important factor that significantly affects IT performance. Traditionally, most datacenter managers have relied upon the use of ambient air cooling solutions (alternating cool and hot rows) to meet their cooling needs. However, ambient air cooling solutions are often unable to handle high heat loads, are not targeted, and can be cost and energy inefficient. As power-intensive applications and server densities have increased, datacenter managers are seeking new ways to dissipate heat bi-products. Accordingly, the use of liquid cooling solutions has become an increasingly popular part of many datacenter cooling strategies. You can best mitigate heat issues if you have a thorough heat dissipation plan and invest in scalable cooling solutions. Below is a short overview of the two main approaches to data center cooling ambient air cooling and liquid cooling.

Remote power management solutions allow administrators to remotely power cycle servers and devices and troubleshoot problems, both locally and remote, from any location in the world. This provides administrators with the ability to manage servers more efficiently and reduce server downtime by affording direct access to power control. Remote power management solutions are also used by many businesses and organizations to manage servers at offices and branch locations where there are no IT staff members, offering cost-efficient “lights-out” operation at those sites.Remote power management solutions add increased functionality over traditional metered and basic power products. While many power distribution units (PDUs) can provide basic information and amperage readings, only intelligent or ‘switched’ PDUs truly provide the benefit of outlet-level management.To read the full article on remote power as one of the datacenter's top challenges visit:http://www.42u.com/benefiting-remo
