Hola,
Tenemos que comprar unos servidores duales para cálculo intensivo con 16Gigas de ram. Nos surge la duda de si comprarlos con 2 Opteron 2.4GHz (3500€)o 2 XEON Woodcrest 2.33GHz (5400€). La diferencia es de 1800€ entre uno y otro.
Queríamos sabes si OPENSUSE trabaja bien con Woodcrest y si la diferencia de precio creéis que merece la pena...
Me había olvidado de una pregunta (la ultima): No se si OPENSUSE trabaja bien con Woodcrest. Lo que si se, es que el desarrollo del micro AMD64 (Opteron, y luego derivados como Athlon64 y Turion), fue desarrollado con el apoyo Suse y Transmeta, mientras Linus Torvalds trabajaba para esta empresa, por lo que los micros que mejor conocen los desarrolladores del kernel y de Suse, son los AMD64 con su set de instrucciones. En otro momento he posteado links sobre el tema, donde Linus Torvalds demuestra su discontento cuando intel anunció "su" EMT64, sin que estos emitan ni una sola palabra acerca de los creadores del set de instrucciones X86-64. Por otro lado, otro detalle que no hay que pasar por alto, son los clasicos bugs que aparecen en los micros nuevos de intel, contra el "veterano" probado y depurado Opteron de AMD. Otro link que me quedaba sobre la comparativa, era sobre otro sitio de hardware: http://www.anandtech.com/IT/showdoc.aspx?i=2892&p=12 Esta es la ultima pagina, con la conclusiones: AMD Socket-F Opteron vs. Intel Woodcrest Seeing as we believe that most servers do not operate at CPU utilizations levels which approach saturation, Socket-F has done very well. It is able to keep up to Woodcrest for the first 3/5 of the Load Points and with less power. Many companies will add more servers/CPUs/etc. once they are running at over 60% CPU utilization, so we do feel that the first three Load Points are the most meaningful. Yes, Woodcrest is faster, but the FB-DIMMs do serve to hinder performance and performance/Watt in our testing. It would appear the major difference between the Opteron 285 and 2218 is power consumption. 2218 is comparable on performance but uses significantly less power at the same time. Is this any indication about what we can expect from K8L? If K8L keeps the low power requirements but improves performance over AMD's current offerings, they should be in good shape later this year. Some might wonder if a different - read Intel - motherboard for the Woodcrest system could have significantly altered the outcome of these tests. We do not think so. Although the Intel motherboards do tend to show slightly lower power consumption, it is not a significant difference. All things considered, the Opterons are holding their own and doing very well for an architecture which is 3.5 years old. Only companies that are routinely running their servers near capacity are likely to truly benefit from an upgrade at this point in time. --------------------------------------------------------------------- Para dar de baja la suscripción, mande un mensaje a: opensuse-es+unsubscribe@opensuse.org Para obtener el resto de direcciones-comando, mande un mensaje a: opensuse-es+help@opensuse.org
