Data Center Evolution

Why Consolidate?

1. Cost savings and maximizing efficiencies

2. Speed (access to data and faster deployment)

3. Simplification

Considerations

• Consolidation offers an opportunity to automate and streamline processes

70% of IT budgets are being consumed by operating costs

Consolidate

Traditional Data Centers

Challenges

• Poor utilization of IT resources, Server Sprawl: power, space, cooling

• Duplicated networks with dedicated functions

• High costs of maintenance, server/support and application licensing.

Traditional Network operating environment

• Dedicated Servers with a 1:1 ratio for applications

• Separate networks for data and storage (and HPC)

• Operational Consistency is simple

Consolidating Traditional Data Center

Benefits

• 60% Reduction in Networking Infrastructure

• Save 40% on power and cooling

Data Center Consolidation steps

• Replace multiple and redundant 1GbE adapters with

10GbE adapters, 2 and/or 4 Gb Fibre Channel HBAs with

8Gb HBAs

• Virtualize the Servers

Adapter requirements

• Partitioning (used to segregate adapters for applications)

• Configure traffic classes & implement QoS for deterministic

performance

• Configurable for teaming, trunking and failover

Virtualization Promises

Something for Everyone

• For server teams:

– Virtualization simplifies server provisioning.

• For application owners:

– Virtualization accelerates application deployment.

• For facilities personnel:

– Virtualization reduces power, space, and cooling

requirements by eliminating physical hardware.

• For CIOs:

– Virtualization increases hardware utilization, lowers

costs and adds flexibility.

– Virtualization is the foundation for cloud computing

One app per server simplifies the policy configuration task

– Each switch port and adapter only needs to handle one policy

– Authorization, Access Control, VLANs/VSANs, QOS

– In effect, creates separate red, blue and green networks

Converging For Efficiency

Convergence

1. Cost savings and maximizing efficiencies

2. Speed (access to data and faster deployment)

3. Simplification

Key Factors For Convergence

• Not rip and replace

• Start at the edge and move to the core

• Walk before you run

Data Center Bridging • Pause IEEE 802.3X – defines link level flow control and specifies protocols, procedures

and managed objects that enable flow control full‐duplex Ethernet links to prevent lost packets

• Priority Flow Control (PFC) IEEE 802.1Qbb – enhances pause mechanism to achieve flow control of 8 traffic classes by adding priority information in the flow control packets (http://www.ieee802.org/1/files/public/docs2008/bb-pelissier-pfc-proposal-0508.pdf)

• Enhanced Transmission Selection (ETS) IEEE 802.1Qaz – assigns traffic classes into priority groups and manages bandwidth allocation and sharing across priority groups (http://www.ieee802.org/1/files/public/docs2008/az-wadekar-ets-proposal-0608-v1.01.pdf)

• Data Center Bridging Exchange Protocol (DCBX) IEEE 802.1Qaz – “Advertisement/configuration” to allow devices to automatically exchange DCB link capabilities (http://www.ieee802.org/1/files/public/docs2008/az-wadekar-dcbx-capability-exchange-discoveryprotocol-1108-

v1.01.pdf)

• Congestion Notification (CN) IEEE 802.1Qau – allows bridges to send congestion signals to end-systems to regulate the amount of network traffic

Cloud – Do You Take Yours Public,

Private or Hybrid

Cloud

1. Cloud – not one thing but many

1. Public vs Private vs Hybrid

2. Infrastructure as a Service (IaaS)

3. Platform as a Service (PaaS)

4. Software as a Service (SaaS)

Considerations For Cloud

– Readiness of Current IT Infrastructure

– Storage Infrastructure in cloud

– Migration of storage to cloud

– Application isolation, security, and privacy

What Are Cloud Services?

• Infrastructure as a Service (IaaS) is a provision model in which an organization outsources the equipment used to support operations, including storage, hardware, servers and networking components. They provision compute, storage, network, and other fundamental computing resources from which the user can deploy and run arbitrary software

• Platform as a Service (Paas) applications are solutions targeted at software development and testing, which are used by IT as well Engineering (R&D) in software development companies.

• Software as a Service (SaaS) applications are solutions for general business process functions, including sales, finance, marketing, and other general business functions
