2. Cloud Computing (Definiciones)
Wikipedia:
“Cloud computing es un paradigma que permite ofrecer servicios de computación a
través de Internet”
Russ Daniels HP:
“Escalado horizontal, control de recursos en grado fino, autoservicios, coste variable
según uso”
ServePath:
“The use of a 3rd party service to perform computing needs on a publicly accessible
IP basis. Cloud computing services are usually performed in consolidated Data Centers
to keep costs low while improving overall utilization”
Elementos habituales en todas las definiciones:
 Acceso a través de Internet (la “nube”)
 Virtualización
 Escalabilidad
 Coste por uso

3. Cloud Computing: Conceptos
Definimos a “Cloud Computing” como un estilo de computación donde los
recursos de IT son:
Brindados a los clientes como un servicio utilizando tecnologías de Internet.
Masivamente escalables.
De alcance global.
Distribuibles dinámicamente, “a demanda” en cantidad y calidad medibles.
Asignados Just in Time
Servicios a múltiples clientes que comparten los mismo recursos. (Multi-Tenant)
Se paga solo por el servicio que se utiliza.
La virtualización es el fundamento para avanzar hacia los servicios del cloud
computing

4. SaaS, PaaS, IaaS ?!!? Los “xaaS”
 SaaS (Software as a Service): Significa una sola instancia de un software o
aplicación que corre en la infraestructura del proveedor y sirve a múltiples
organizaciones de clientes.
 Ejemplo: Salesforce.com
 PaaS (Plataform as a Service): Es la encapsulación y la abstracción de un
ambiente de desarrollo.
 Ejemplo: Amazon EC2
 IaaS (Infraestructura as a Service): Es un medio de entrega de
almacenamiento y capacidades de cómputo como servicios estandarizados en
la red.
 Ejemplo: rackspacecloud.com

8. Virtualización
 La Virtualización consiste en la abstracción de los recursos físicos
existentes en un equipo informático para poder correr sobre el
mismo equipos virtuales.
 Cada uno de estos equipos virtuales ve un servidor completo,
interactuando con el mismo a través de la tecnología de
virtualización.

9. ¿Qué se puede virtualizar?
 Servidores (VMs, la nueva unidad atómica en el DC)
 Networking. (Switches, Load Balancers)
 Seguridad. (Firewall)
 Almacenamiento. (Storage)

25. Data Center Access Layer Options
Top of Rack (ToR)
• Typically 1-RU servers
• 1-2 GE LOMs
• Mostly 1, sometimes 2 ToR switches
• Copper cabling stays within rack
• Low copper density in ToR
• Higher chance of East-West traffic hitting
aggregation layer
• Drives higher STP logical port count for
aggregation layer
• Denser server count
Middle of Row (MoR) (or End of Row)
• May be 1-RU or multi-RU servers
• Multiple GE or 10GE NICs
• Horizontal copper cabling for servers
• High copper cable density in MoR
• Larger portion of East-West traffic stays
in access
• Larger subnets  less address waste
• Keeps agg. STP logical port count low
(more EtherChannels, fewer trunk ports)
• Lower # of network devices to manage

35. NON-Unified Fabric – Phase 0
A Segregated LAN and SAN…
In existing architectures, LAN and SAN
connectivity is segregated directly from the
Servers, where NICs and HBAs connect into
Ethernet switches and Fibre Channel Fabrics.
This may result in excess of 8+ cables to/from
each physical server
In Ethernet, redundancy relies upon
technologies such as Spanning Tree Protocol
to provide a loop-free topology...
Business and Technology Working as One

36. Unified Fabric – Phase 1
A Unified Fabric in the Access…
The Nexus 5000 allows for the consolidation of
Ethernet and Fibre Channel to be carried across
the same physical piece of cable - Ethernet
Leveraging standards-based FCoE, the Nexus
5000 is able to provide direct FCoE connectivity
from the Server through a Converged Network
Adapter (CNA) to the Nexus 5000.
The Nexus 5000 is then able to perform Ethernet
switching for regular Ethernet frames, and Fibre
Channel forwarding for FC frames...
Business and Technology Working as One

37. Unified Fabric – Phase 2
Unified Fabric in the Data Center
Once FCoE-enabled modules become available
on the Nexus 7000 or the MDS 9500 series
platforms, multi-hop FCoE topologies may be
possible by retaining FCF capabilities across the
different platforms
Additionally, with the introduction of direct FCoE
attached targets, these may also be directly
connected to any of these FCoE-enabled
devices...
Business and Technology Working as One

38. Key Benefits of Unified Fabric
Reduce overall DC power consumption by up to
8%. Extend the lifecycle of current data center.
Wire hosts once to connect to any network - SAN,
LAN, HPC. Faster rollout of new apps and
services.
Every host will be able to mount any storage
target. Drive storage consolidation and improve
utilization.
Rack, Row, and X-Data Center VM portability
become possible.
