Nuevas Tecnologías
Si bien hay muchos fabricantes , tan solo 2
marcas en el mercado son las más conocidas
y se alzan como competidoras muy serias.
Hace algunos años Intel estaba a la cabeza tanto
de fabricación como de ventas y distribución,
pero un cambio en el mercado con una fuerte
aparición de AMD ha establecido un nuevo
estándar en las configuraciones de los equipos de
venta directa.
Porqué retrasar el reemplazo de PCs no es
una buena decisión tecnológica ni
financiera?
“El consejo que continuamente les doy a
mis colegas de IT es que demuestren
el valor que trae al negocio cualquier
gasto en tecnología.
Habiendo sido CIO, siempre he creído que
los gastos en tecnología deben verse como
un activo para la compañía, y no como un
costo para mantener operando el negocio”
Stacy Smith, Intel CFO
El dilema actual
• Derivado de la crisis económica mundial
muchas organizaciones están retrazando el
reemplazo de equipo de cómputo para reducir
sus costos
• Pareciera una decisión correcta (menos dinero
que gastar), sin embargo. . .
– Qué hay del costo asociado de mantener equipo viejo ? (mayor
a 3 años)
– Qué hay del mayor consumo de energía asociado a equipos
viejos ?
– Qué hay de los mayores riesgos de seguridad ?
– Qué hay del costo por m² que ocupan los servidores viejos ?
Porqué los equipos a partir de 3 años
cuestan más?
•
En promedio el costo de mantenimiento
de un equipo después del 3er año se
incrementa en un 59% (*)
Impresoras (6%)
Equipo LAN (7%)
•
Un equipo de 3 años o más consume
80% más energía eléctrica (*)
– Los datacenters acaparan la atención debido a la
concentración de equipos, sin embargo las PC‟s y
sus periféricos consumen mucha más energía

Intel sugiere considerar los siguientes
aspectos al evaluar una renovación de
equipo de cómputo
• Productividad de los empleados
• Costos energía eléctrica & eficiencia energética
• Costos operativos (administración y soporte)
• Costos asociados a problemas de seguridad
informática
• Costos asociados al paro de labores originado
por desastres naturales o problemas de salud

AMD Habla De Su Primera
Arquitectura Completamente Nueva
• Nuestro equipo editorial, ha llevado a cabo una
excelente labor para informales todo lo último que ha
"comentado" AMD durante el AMD Analyst Day en
relación a su futuro en el sector de los procesadores.
Así, ya les hemos contado sobre sus futuras plataformas
deEscritorio, Móviles y Servidores, les hemos hablado
del Sandtiger Octa-Core, de la tecnología G3 Memory
Extender, los procesos de fabricación, y por supuesto
del ya conocido Barcelona. Sin embargo, esto no es
todo, y a continuación queremos introducirlos en
algunos nuevos conceptos, fundamentales para AMD,
que son la base de todo lo recién indicado y que
permitirá complementar la excelente cobertura ya
entregada y mencionada en las líneas superiores.
1.- M-Space.
• Tal como se indicó, AMD planea lanzar
su plataforma Opteron de tercera generación, el
año 2009, con el procesador Sandtiger OctaCore. Bajo este procesador, se encuentra un
nuevo acercamiento de la Compañía, modular,
denominado M-Space. De acuerdo a la gente
de AMD, M-Space permite mezclar y calzar
funciones de una CPU para determinadas
tareas.
"Acercamiento modular de
M_Space"
Definición de M-SPACE
•
La definición de M-Space, es la siguiente,
– a.- Modular: "Bloques de diseño" reconfigurables para mayor agilidad
y velocidad.
– b.- Escalable: Escalamiento linear de rendimiento "multi-thread" y
"single-thread“.
– c.- Portabilidad: Eficiencia energética para mayor portabilidad y
movilidad.
– d.- Accesibilidad: Compromiso a una innovación abierta.
– e.- Compatible: Compatibilidad hacia atrás y facilidad de actualización.
– f.- Eficiencia: Eficiencia óptima en el chip y a nivel de Entrada/Salida.
"Definición del concepto M-Space"
• Como se puede apreciar, M-Space es una
completa redefinición de la estrategia de diseño
de AMD, la cual, como se mencionó, es la base
del Sandtiger.
• Pese a lo anterior, este
nuevo procesador también incluye otro
concepto, no menos interesante, eje central de
los planes futuros de la Compañía, el cual
pasamos a revisar a continuación.
2.- Bulldozer.
• El Sandtiger de 8 núcleos de AMD, consiste en
8 Bulldozers. Suena extraño el nombre, el cual ha sido
asociado a una intención, por parte de la Compañía, de
demoler el mercado con este producto.
• Bulldozer, es el nombre que la Empresa le ha dado a
uno de los núcleos de CPU que se basan en la ya
mencionada arquitectura M-Space. AMD ha indicado
que se obtendrán mejoras dramáticas en rendimiento
por watt, en aplicaciones de Computación de Alto
Rendimiento ("High Performance Computing" o "HPC"),
al usar los núcleos Bulldozer.
"Objetivo del nuevo núcleo
Bulldozer"
• Lo interesante del tema, es que a diferencia
de Barcelona y Shangai, los cuales corresponden a una
evolución de la longeva arquitectura K8, Bulldozer es
algo totalmente nuevo y diferente.
• AMD colocará 8 núcleos Bulldozer en el Sandtiger, con
un controlador de memoria. Segúnla Compañía, el
concepto detrás de M-Space podrá verse en este
producto al optimizarse el diseño para Servidores y
elevar la vara del rendimiento por watt, tanto para
aplicaciones "single-threaded" como para aquellas
"multi-threaded". Algunos expertos ya hablan de
plataformas capaces de "mutar" de acuerdo a los
requerimientos de las aplicaciones.
3.- Fusion.
• La arquitectura M-Space, también puede
relacionarse con la comentada
tecnologíaFusion, la cual
mezcla CPUs y GPUs.
• AMD planea mezclar y calzar componentes del
concepto M-Space en Falcon, un
procesador Fusion optimizado
para Computadores de Escritorio mainstream, y
paraPortátiles. Falcon es la base de la
plataforma de rango medio
de Escritorio de AMD, llamada Copperhead.
"Componentes del Falcon-Fusion"
• Falcon cuenta con cuatro núcleos Bulldozer,
junto a un procesador gráfico integrado.
Esta GPU, soporta tecnología DirectX 10,
posiblemente DX11, y cuenta con la tecnología
de AMD denominada Universal Video Decoder o
UVD. También posee un PCIe integrado.
4.- Bobcat.
• Junto con Bulldozer, AMD cuenta con el
núcleo Bobcat, también para
procesadoresFusion, diseñado para
aplicaciones moviles, ultra-móviles y
de electrónica de consumo.Bobcat también es
un diseño completamente nuevo y cuenta con
grandes capacidades de escalamiento
energético. Los procesadores basados
en Bobcat pueden llegar a consumir sólo 1
watt de energía. No se conocen mayores
detalles de los procesadoresFusion con
"tecnología Bobcat".
"El Bobcat dirigido al sector móvil"
5.- GPUs.
• Cuando AMD compró ATI, obviamente era con
una idea fija en mente. En efecto, la
Compañía está plenamente convencida que el
desarrollo gráfico, y por supuesto la ya tan
comentada integración con CPUs, es más
importante que dedicarse sólo al diseño
deprocesadores. Obviamente, ambos conceptos
están fuertemente arraigados e
interrelacionados en los Roadmaps de la
Compañía.
"Nuevas tecnologías gráficas de
AMD-ATI, primera parte"
• Después del desastre que se ha obtenido con la
incursión de AMD en el mundo DirectX 10,
muchos pueden mirar con cierta mofa a la
Compañía, cuando ésta se refiere a gráficos de
la siguiente generación.
"Nuevas tecnologías gráficas de
AMD-ATI, segunda parte"
• Para el común de las personas, ATI es sinónimo
de tarjetas de video para jugar. Sin embargo, no
debe olvidarse que ésta, siempre ha sido un
fuerte suministrador de productos para
dispositivos móviles, y AMD intenta continuar en
esa línea, fortaleciéndola, al integrar tecnologías
que se observan en los PCs, a los más variados
dispositivosportátiles.
6.- Palabras Finales.
• Tiempo atrás, AMD fue muy criticada por guardar silencio
en relación a sus nuevos proyectos y tecnologías. Incluso,
se llegó a decir que eso había influido en los últimos
"fracasos" de la Compañía. En esa oportunidad, AMD se
comprometió a ser "más abierta".
• Claramente, la Empresa ha cumplido con lo prometido,
pero se ha ido al otro extremo. Nos ha llenado de
anuncios, conceptos, nombres, etc. Todo bien, claro que
esto debe plasmarse en lanzamientos reales ya que
muchos simplemente, cuando miran hacia AMD, piensan,
• "…ver para creer.“
• Ciertamente, Bulldozer, sin desmerecer las otras
tecnologías, será el "caballo de batalla" de AMD. Es un
alejamiento definitivo de la fiel plataforma K8, pero al
mismo tiempo es un tremendo desafío.

de AMD"

POWER7 systems are over twice as good as POWER6 systems!

Twice the performance:
Power 780 32-core performance per core is over twice
the Power 570 32-core

Twice the scaling:

Twice the capacity:
Power 770
and 780 both offer twice the number of cores as the
largest Power 570
Power 770 and 780 offer more than twice (~3 times) the
throughput of the largest Power 570

Twice the memory:
- Over twice the physical memory of the Power 570
- Active Memory ExpansionTM enables up to twice the
effective memory compared to what is physically
installed

Twice the energy efficiency:
Power 770 & 780 offer over twice the performance per
watt (up to 3 times) than the most efficient Power 570

Twice the cores for the same price:
Buy twice the cores with the Power 770 and pay less
than a comparable POWER6 based Power 570

Active Memory Expansion Recommendation:
--------------------The recommended AME configuration for this workload is to configure
the LPAR with a memory size of 5.50 GB and to configure a memory
expansion factor of 1.51. This will result in a memory expansion of
45% from the LPAR's current memory size. With this configuration,
the estimated CPU usage due to Active Memory Expansion is
approximately 0.58 physical processors, and the estimated overall
peak CPU resource required for the LPAR is 3.72 physical processors.

I/O Upgrade Considerations
• All the newer IBM I/O drawers (12X), disk, SSD and PCI adapters used on POWER6
supported on POWER7 servers
– May need to move 3.5-inch SAS drives and PCI-X adapters
• Older I/O on POWER6 servers, but not on POWER7 servers
– RIO/HSL I/O drawers
– SCSI disk smaller than 69GB or SCSI drives slower than 15k rpm

Power SODs for Upgrades
Definition “upgrade” as a model change keeping same serial number
• Power 595
– SOD issued in 2009 & augmented 2010
• Power 570
– SOD issued in 2009
– Upgrades announced Feb 2010, shipping June 2010
– Built on unified structure, 9406-MMA must first convert to 9117-MMA
• Power 575 and 560 and 550
– SODs not issued
• Power 520
– SOD issued February 2010 with plans to be delivered in 2010
– For Power 520 (8203-E4A) 2-core or 4-core servers
– Insight: POWER5 520 to POWER6 520 upgrades did not have savings in the
hardware. Client savings were in easy license transfer (including IBM i), documented
upgrade procedures for upgrading, and perhaps easier leasing/depreciation structure

POWER7 High-End Statement of Direction
• IBM plans to deliver a new high-end server in
2010 with up to 256 POWER7 processor cores
• Designed to operate within the same physical
footprint and energy envelope of the current 64core Power 595 server.
• High-Voltage DC Power option
• IBM also plans to provide an upgrade path from
the current IBM Power 595 server with 12X I/O to
the new POWER7 high-end server.
• Enterprises with multiple systems leveraging
PowerVM Live Partition Mobility may use this
function to maintain application availability
during the upgrade process.
