Industry Trend: Myths and Realities
These are constantly changing and evolving

Myth: Green IT is all about reducing carbon footprint
Reality – Many facets to green IT, there is a Green Gap!
Reality – Power, cooling, floor space, EH&S (PCFE), Recycling
Reality – Business, economic & environment sustainability
Myth: Energy efficiency & optimization is energy avoidance
Reality – 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 costs
Reality – Virtualization is also about enabling agility to sustain growth

Industry Trend: IT Footprint Constraints
Barriers that inhibit growth and improved service delivery

• 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 more
Notes: Space (capacity) centric, more data stored per watt of energy
Time (performance) centric, more work done per watt of energy


Industry Trend: IT Resource Constraints
Demand out-pacing available resources = Bottlenecks

Industry Trend: What’s The Buzz?
No such thing as a data recession, Leverage what you have!

In order to support demand: Available Resources
Don’t save as much data, limit Performance, Availability,
expansion and QoS enhancements Capacity, Energy = PACE
E.g. Store and process more
data in a denser footprint
Or

Leverage improved densities
Remove IT footprint constraints QoS, Service Levels
Response Time, Availability
Boost efficiency, lower unit costs
Improve performance

Do more with what you have Unit Cost of Resource
Avoid compromise of QoS $ / Capacity, $ per IOP
Enable agility and flexibility Capacity per watt, IOP per watt

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

Industry Trend: Next Generation Data Centers
What the “Information Factory” of the future looks like Today!

New and Emerging Time Tested & Field Proven
• Scalable
• Flexible
• Resilient
• Secure
• Efficient

Balance of new and old technologies
Time (Performance) + Availability + Space (Capacity) + Economics
Public and Private Clouds Disk, Tape and Snapshots
CDP, SSD and Dedupe RAID and Replication
Thin provisioning, Virtualization Fibre Channel, iSCSI, NAS
pNFS, FCoE and SAS

Industry Trend: What’s The Buzz?
Closing the Green IT Gap: From Avoidance to Efficiency
Today and Tomorrow
Focus expands to Effectiveness and Productivity
Expand from survival to productivity model
Sidestep political or scientific debates
Support growth and new applications
Remove barriers and constraints
Boost QoS levels per IT cost

Efficiency drive environmental and economic benefits

Past and Present
Focus on Cost and Carbon Footprints
Social and environmental responsibility
Some areas focused on energy avoidance
Conservation and consolidation only go so far!

Industry Trend: Tiered Access Networks
Balance technologies with RTO and RPO requirements

• 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

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?
See Chapter 6 “Resilient Storage Networks” (Elsevier)
