Power

•   According to the Uptime Institute the three year cost of
    powering and cooling servers is currently one and a half times
    the cost of purchasing the server hardware.
•   Server energy demand has doubled from 2000-2005
•   1.2% of the US electrical usage
•   Equal to 5 1,000 MW power plants (study by LBL and Stanford)
•   Cooling and electrical costs represent up to 44 -50% of a data

EPA Announces Data Centers Can Now Earn Energy Star
  Label
EPA Announces Data Centers Can Now Earn Energy Star Label

WASHINGTON – The U.S. Environmental Protection Agency (EPA) announced today that stand-alone data centers and
buildings that house large data centers can now earn the Energy Star label. To earn the label, data centers must be in the top
25 percent of their peers in energy efficiency according to EPA’s energy performance scale. By improving efficiency, centers
can save energy and money and help fight climate change.
EPA uses a commonly accepted measure for energy efficiency, the Power Usage Effectiveness metric, to determine
whether a data center qualifies for the Energy Star label. Before being awarded the Energy Star, a licensed professional must
independently verify the energy performance of these buildings and sign and seal the application document that is sent to
EPA for review and approval.
Data centers are found in nearly every sector of the economy and deliver vital information technology services, including data
storage, communications and internet accessibility. Data centers use a significant amount of energy, accounting for 1.5
percent of total U.S. electricity consumption at a cost of $4.5 billion annually, an amount that is expected to almost double
over the next five years.
Significant energy and cost savings are possible through modest gains in efficiency. The energy consumed by data centers is
growing every year. Based on the latest available data, improving the energy efficiency of America’s data centers by just 10
percent would save more than 6 billion kilowatt-hours each year, enough to power more than 350,000 homes and save more
than $450 million annually.
Through Energy Star, EPA provides a proven energy management strategy and free tools for public and private organizations
to save energy and money through increased energy efficiency.

Data centers can improve energy efficiency in many ways, such as purchasing Energy Star qualified servers and ensuring
that all HVAC equipment functions properly.
PUE
• Also adopted in EU and Japan
• Power Usage Effectiveness
• Defacto standard
• Total power / IT load
• Most data centers are in the 1.9-2.6 range
• The closer to 1 the better
• Requires Intelligent PDU’s or some means to measure USED
  power
• DCIE (Data Center Infrastructure Effectiveness) is 1/PUE to give
  percentage
• PUE Version 2 kWH instead of kW
Green Grid

• The Green Grid is proposing the use of a new metric
• Data center compute efficiency (DCcE)
• and its underlying sub-metric, server compute efficiency (ScE).
• These metrics will enable data center operators to determine the
  efficiency of their compute resources, which allows them to identify
  areas of inefficiency.
• Using DCcE and ScE, data center operators can continually refine
  and increase the efficiency of their compute resources in the same
  way that they use power usage effectiveness (PUE) to improve data
  center infrastructure.
• CUE (Carbon Usage Effectiveness)
• All are relatively new

Ethernet

• All things Ethernet!
• EEE is a game changer, especially for 10GBASE-T
    – Provides a true idle state
    – Significantly lowers power
• Data Center Ethernet collapses the backbone structure – layer 2
  instead of layer 3
• Idea is to increase speed (bridge not route) and provide priority
• Ethernet has a LOT of overhead
• Not intelligent

The need for speed

• Virtualization
• Consolidation
•   Increasing storage requirements
•   More analytics
•   Blade technologies
•   Instant demand for data

TIA-942
  •   Horizontal and Vertical channels shall be run accommodating growth so these
      areas do not have to be revisited
  •   No more bus or direct connections unless specifically REQUIRED by the
      manufacturer
  •   No shared sheath media
  •   Category 6A recommended (echoed by Cisco® 6A or 7) Note: this is an update
      from the original TIA-942 document now TIA 942-2 soon to be combined into TIA
      942-A
  •   OM3 Minimum recommended fiber/ may change to OM4
ISO/IEC 24764
  •   Horizontal and Vertical channels shall be run accommodating growth so
      these areas do not have to be revisited
  •   OM3 minimum recommended figer
  •   All systems shall be connected via a structured cabling system, point to
      point connections are allowed for short run cables in server cabinets only
  •   Category 6A minimum (UTP or F/UTP) Class EA
  •   Category 7 and 7A/Class F and FA
Remember

• 6A and 7A support short reach mode
  (low power mode) for a savings
  estimated at about 1W per port
• In a data center with a PUE of 1.9, 1W
  saved at the server = 2.84W through all
  systems
TIA 942, 942-2, 942-A

• This Standard (942-A) replaces ANSI/TIA-942
  dated April 12, 2005 and its addenda.
• This Standard incorporates and refines the
  technical content of:
   – ANSI/TIA-942, Addendum 1, Data center coaxial
     cabling specifications and application 311 distances
     312
   – ANSI/TIA-942, Addendum 2, Additional guidelines for
     data centers
Expanded Topology
Tier IV Diverse Pathways
Summary of Changes
•   TIA-942-A is harmonized with the TIA-568-C standard series including the topology, terms and environmental
    classifications described in 568-C.0, as well as component specifications in TIA-568-C.2 and C.3.
•   The addenda, TIA-942-1 and TIA-942-2, have been incorporated into 942-A; those two addenda will be
    superseded by TIA-942-A.
•   Grounding and bonding content from TIA-942 has been removed and incorporated into TIA-607-B.
•   Administration content has been removed and incorporated into the proposed TIA-606-B.
•   Most content regarding cabinets/racks and power/telecommunications separation has been removed and
    incorporated into the proposed TIA-569-C.
•   Outside-plant pathways content has been removed and incorporated into TIA-758-B.
•   The 100-meter length limitation for optical-fiber horizontal cabling has been removed. Horizontal cabling
    distances for optical fiber are based on individual application requirements.
•   Category 3 and Category 5e are no longer recognized for horizontal cabling. The draft recognizes Category 6
    and Category 6A balanced twisted-pair cable types for horizontal cabling. Both types of cabling are still
    permitted for backbone cabling.
•   The recognized multimode optical fiber cable for horizontal and backbone cabling has been changed to OM3
    and OM4 850-nm laser-optimized 50/125-micron multimode fiber cable. OM1 and OM2 are no longer
    recognized in TIA-942-A.
•   The recognized optical-fiber connectors are LC for one or two fibers and MPO for more than two fibers.
•   The intermediate distribution area (IDA) has been added to the data center topology.
•   An allowance for midspan powering equipment in the zone distribution area (ZDA) has been removed.
•   A section on energy efficiency has been added.
•   The terms "equipment outlet" (EO) and "external network interface" (ENI) from the ISO/IEC 24764 standard
    have been added.

Why Use a Structured System?

•   Greatest Versatility over time
•   Significant costs savings in switches day one
•   Significant savings in power and maintenance costs day two
•   Point to point connections create spaghetti
•   Point to point can lock you into a single vendor solution
•   Cable abatement is difficult in a point to point system
•   Pathways are properly sized and filled
Passive copper HSI assemblies

• Small Form Factor (SFF) connectors terminated to twinaxial cable
  that facilitate direct connections between switch, server, and storage
  equipment

Patch Panels in Switch Cabs

• Cables are Easier to Trace
• Easier when blade changes are
  required
• Wire management is easier
• Colder air at bottom of cabinet is
  better for equipment
   – Failure rate at top 1/3 of cabinet is 3x
     greater than bottom 2/3’s
• May be required due to
  power/cooling constraints

    EPA Announces DataCenters Can Now Earn Energy Star Label EPA Announces Data Centers Can Now Earn Energy Star Label Release date: 06/07/2010 Contact Information: Enesta Jones, jones.enesta@epa.gov, 202-564-7873, 202-564-4355 WASHINGTON – The U.S. Environmental Protection Agency (EPA) announced today that stand-alone data centers and buildings that house large data centers can now earn the Energy Star label. To earn the label, data centers must be in the top 25 percent of their peers in energy efficiency according to EPA’s energy performance scale. By improving efficiency, centers can save energy and money and help fight climate change. EPA uses a commonly accepted measure for energy efficiency, the Power Usage Effectiveness metric, to determine whether a data center qualifies for the Energy Star label. Before being awarded the Energy Star, a licensed professional must independently verify the energy performance of these buildings and sign and seal the application document that is sent to EPA for review and approval. Data centers are found in nearly every sector of the economy and deliver vital information technology services, including data storage, communications and internet accessibility. Data centers use a significant amount of energy, accounting for 1.5 percent of total U.S. electricity consumption at a cost of $4.5 billion annually, an amount that is expected to almost double over the next five years. Significant energy and cost savings are possible through modest gains in efficiency. The energy consumed by data centers is growing every year. Based on the latest available data, improving the energy efficiency of America’s data centers by just 10 percent would save more than 6 billion kilowatt-hours each year, enough to power more than 350,000 homes and save more than $450 million annually. Through Energy Star, EPA provides a proven energy management strategy and free tools for public and private organizations to save energy and money through increased energy efficiency. Data centers can improve energy efficiency in many ways, such as purchasing Energy Star qualified servers and ensuring that all HVAC equipment functions properly.

    PUE • Also adoptedin EU and Japan • Power Usage Effectiveness • Defacto standard • Total power / IT load • Most data centers are in the 1.9-2.6 range • The closer to 1 the better • Requires Intelligent PDU’s or some means to measure USED power • DCIE (Data Center Infrastructure Effectiveness) is 1/PUE to give percentage • PUE Version 2 kWH instead of kW
  • 9.
    Green Grid • TheGreen Grid is proposing the use of a new metric • Data center compute efficiency (DCcE) • and its underlying sub-metric, server compute efficiency (ScE). • These metrics will enable data center operators to determine the efficiency of their compute resources, which allows them to identify areas of inefficiency. • Using DCcE and ScE, data center operators can continually refine and increase the efficiency of their compute resources in the same way that they use power usage effectiveness (PUE) to improve data center infrastructure. • CUE (Carbon Usage Effectiveness) • All are relatively new

    TIA-942 • Horizontal and Vertical channels shall be run accommodating growth so these areas do not have to be revisited • No more bus or direct connections unless specifically REQUIRED by the manufacturer • No shared sheath media • Category 6A recommended (echoed by Cisco® 6A or 7) Note: this is an update from the original TIA-942 document now TIA 942-2 soon to be combined into TIA 942-A • OM3 Minimum recommended fiber/ may change to OM4 ISO/IEC 24764 • Horizontal and Vertical channels shall be run accommodating growth so these areas do not have to be revisited • OM3 minimum recommended figer • All systems shall be connected via a structured cabling system, point to point connections are allowed for short run cables in server cabinets only • Category 6A minimum (UTP or F/UTP) Class EA • Category 7 and 7A/Class F and FA
  • 15.
    Remember • 6A and7A support short reach mode (low power mode) for a savings estimated at about 1W per port • In a data center with a PUE of 1.9, 1W saved at the server = 2.84W through all systems

    Summary of Changes • TIA-942-A is harmonized with the TIA-568-C standard series including the topology, terms and environmental classifications described in 568-C.0, as well as component specifications in TIA-568-C.2 and C.3. • The addenda, TIA-942-1 and TIA-942-2, have been incorporated into 942-A; those two addenda will be superseded by TIA-942-A. • Grounding and bonding content from TIA-942 has been removed and incorporated into TIA-607-B. • Administration content has been removed and incorporated into the proposed TIA-606-B. • Most content regarding cabinets/racks and power/telecommunications separation has been removed and incorporated into the proposed TIA-569-C. • Outside-plant pathways content has been removed and incorporated into TIA-758-B. • The 100-meter length limitation for optical-fiber horizontal cabling has been removed. Horizontal cabling distances for optical fiber are based on individual application requirements. • Category 3 and Category 5e are no longer recognized for horizontal cabling. The draft recognizes Category 6 and Category 6A balanced twisted-pair cable types for horizontal cabling. Both types of cabling are still permitted for backbone cabling. • The recognized multimode optical fiber cable for horizontal and backbone cabling has been changed to OM3 and OM4 850-nm laser-optimized 50/125-micron multimode fiber cable. OM1 and OM2 are no longer recognized in TIA-942-A. • The recognized optical-fiber connectors are LC for one or two fibers and MPO for more than two fibers. • The intermediate distribution area (IDA) has been added to the data center topology. • An allowance for midspan powering equipment in the zone distribution area (ZDA) has been removed. • A section on energy efficiency has been added. • The terms "equipment outlet" (EO) and "external network interface" (ENI) from the ISO/IEC 24764 standard have been added.

Editor's Notes

  • #29 The three most commonly deployed passive copper HSI assemblies are shown here. These assemblies are used to support short length direct connections, which are typically 7 meters or less. These assemblies feature small form factor connector interfaces that are terminated to twinaxial cable. The type of passive copper HSI cable assembly required for a given project is dependent upon the application supported by the network equipment and the connection distance. Note that the gage of the twinaxial cable that these assemblies are constructed from typically varies from 30 to 24 AWG and the gage size specified is related to the application support distance. For instance, 30 gage assemblies support a reach or 3 meters, which is ideal for Top of Rack deployments and 24 gage assemblies support a reach of 7 meters, which is ideal for Middle of Row deployment. Unlike structured balanced twisted-pair copper cabling systems, which support bi-directional transmission, high speed interconnects only support transmission in one direction. Therefore, in a manner that is similar to optical fiber media, a minimum of two pairs are required to transmit and receive data between two connected network devices.Siemon Interconnect Solutions supports 2-pair SFP+, 8-pair 8470 or CX4, and 8-pair QSFP+ passive copper high speed interconnect interfaces. 2-pair SFP+ assemblies are a cost-effective and lower-power alternative to optical cables for short reach links and support data transfer rates up to 10 Gb/s over both the transmit and receive pairs. 8-pair 8470 or CX4 assemblies are designed to support an array of infrastructures such as high-performance computing, enterprise networking, data centers, network storage, and Ethernet CX4 up to 10Gb/s over the four transmit pairs and the four receive pairs. In some implementations of InfiniBand, 8470 assemblies can support data rates up to 40 Gigabits per second. QSFP+ or Quad SFP+ represents the state-of-the art in high speed interconnect technology and can support transmit and receive speeds of up to 40 Gb/s over the four transmit pairs and the four receive pairs.  It is important to note that not all SFP+ cable assemblies are interoperable and some equipment (such as HP&apos;s) may have been programmed or encrypted to work only with the brand or specific cable assemblies that were packaged with the equipment.  
  • #46 40Gig Ethernet on multimode is similar to 4 lane (4x) Infiniband. 4 strands transmit and 4 strands receive. In 40GbE the data is divided into packets and each is numbered. As they transmit down the fibers, the receiving end reads the packet segment numbers and puts the packet back together. MTP trunks fully support 40GbE without the need for zero bit skew trunks because of this.
  • #47 When we move to 100GbE there are actually 3 options for MMF. A user can have one 24 strand MTP trunk (we ignore the strands at the outside) or two 12 strand MTP trunks mounted over and under or side by side in the electronics. Due to the existing number of 12 strand trunks already installed, you will likely see all of these options
