Networks (LAN, SAN, MAN, WAN)

Industry Trend: Data Growth and AccessThere is NO such thing as a data or processing recession


Myth: Green IT is all about reducing carbon footprintReality – Many facets to green IT, there is a Green Gap!Reality – Power, cooling, floor space, EH&S (PCFE), RecyclingReality – Business, economic & environment sustainability

Myth: Energy efficiency & optimization is energy avoidanceReality – Also doing more work faster with less energy

Myth: Server efficiency is capacity optimization (consolidation)Reality – Its also about time (performance) improvement

Myth: Virtualization is all about consolidation to reduce costsReality – Virtualization is also about enabling agility to sustain growth

Power, Cooling, Floor space, Environmental (PCFE) Constraints

Industry Trend: Myths and RealitiesThese are constantly changing and evolving

• People/staffing – Resources managed per person

• Time windows – Backup/recovery, BC/DR, provisioning

• Cabinet/Floor space – Habitats for technology

• Software licenses – Stretch available licenses further

• Power (primary/standby) – More work per watt of energy

• Cooling/HVAC – Do more work per Btu or ton of cooling

• Available budgets – Stretch budgets to do moreNotes: Space (capacity) centric, more data stored per watt of energy

Time (performance) centric, more work done per watt of energy

E.g. Store and process more data in a denser footprint

Note: Innovation = Do and enable more with less without compromising customer service

The need for speed. Fast servers need fast I/O networks and fast storage mediums and devices. Slow storage and I/O networks causes fast servers to have to wait resulting in lost productivity and resource waste!

Considerations: How much distance is needed? What are the latency requirements? How much data needs to be moved in what timeframe? What are the RTO and RPO needs?

What applications are involved? What are budget and network constraints?

• What are your applicable threats/risks?• What are applicable techniques? Mirroring, Snapshots, Replication, CDP Remote backup and archiving Physical or electronic transport of tapes/media

• What are some technologies PCIe, SAS, FC, FCoE, Ethernet, InfiniBand IOV, LAN, SAN, MAN, WAN Storage over IP (iSCSI, FCIP, NAS) WAFS, DRO, WADM and other optimizers

A large market and IT virtualization

opportunity!

Consolidation appliesonly to a fractionof all serversor storage

Issues That Inhibit Consolidation:• QoS and performance barriers • Politics and financial constraints • Competitive or legal purposes• Security and compliance

Market and IT opportunity = Life beyond consolidationUsing server or storage virtualization for IT resource

management enabling abstraction and transparency for massive scaling, BC, DR & routine infrastructure resource

management (IRM) operational functions

• Emulation• Abstraction• Aggregation• Migration

ActionNon-consolidatedservers or storage

Tomorrow

Today


Industry Trend: Virtualization (Next Phase)Life beyond consolidation: Abstraction, emulate and agility


• IT data centers are information factories End to end (E2E) cross technology management becomes essential Gain situational awareness of resource usage and effectiveness!

• Many approaches/technologies depending upon issues Avoid simply moving IT problems or bottlenecks around Solve problems and issues to enable IT and business growth Small changes on large basis have big impacts

• Balance between futures and what works today Align correct technology to business requirements and objectives Utilize tiered storage and tiered data protection Leverage virtualization to bridge from the past to the future
