Cabinet Seismic Ratings: Reduce the Risk of Downtime

Blog Category: , by

The International Building Code (IBC) determines that certain facilities – data centers often included – remain operational during and after earthquakes or other seismic events. Based on building type, and how vital a building’s operations are, facilities are placed into four IBC-determined risk categories:

  • Risk Category 4: Hospitals, aviation control towers, police/fire stations, facilities containing highly toxic materials
  • Risk Category 3: Lecture halls, theaters, power-generations stations, water treatment plants, prisons
  • Risk Category 2: buildings that don’t fall into Risk Categories 1, 3 or 4
  • Risk Category 1: storage buildings and agricultural facilities

Data centers typically fall into Risk Category 4, meaning that their operation is regarded vital during and after an earthquake. To protect against downtime, it’s pivotal to minimise the potential for equipment damage during seismic events – especially if data centers are not backed up at a secondary location. Some data centers are considered vital to conserving communication exchange (wireless, email, voice, etc.) after a seismic event.

High-Speed Optical Links: Checkpoint 2 for Fiber Infrastructure Deployment

Blog Category: , by

All the devices housed in today’s data centers – from virtualization equipment to storage devices – require cabling that provides high performance and flexibility. Because of this, distributing new fiber infrastructure in data centers demand  much thought and planning.

We advise keeping these four essential checkpoints in mind:

  1. Determine the active equipment I/O interface based on application types
  2. Choose optical link media based on reach and speed
  3. Verify optical fiber standards developed by standards bodies
  4. Validate optical link budget based on link distance and number of connection points

In a series of blogs – the first one published on March 23, 2017– we will cover each of these checkpoints in detail, describe current technology trends and the latest industry standards for data center applications. This blog covers checkpoint No. 2: choosing optical link media based on reach and speed.

Category Cables; Planning for Power Delivery

Blog Category: , , , by

The utilisation of category cables for power delivery has been getting ample attention lately – especially given the amendment in NEC (2017), NFPA 70 (2017) and potentially CEC C22.1 (2017 proposed revisions). This attention is related to potential safety issues that may emerge when high power, high temperature and high cabling density are present.

The National Fire Protection Association (NFPA), Chapter 3, Table 725.144, “Transmission of Power and Data,” contains information about the ampacity rating of conductors at various temperature ratings based on gauge and bundle size. UL has created LP certifications (optional – not required by code) to identify cables that are designed and tested to carry the marked current under reasonable worst-case installation scenarios without exceeding the cable’s temperature rating.

This arose through an allowance in the older version of NEC, which allowed electricians to substitute Class 2 and Class 3 data cables (category cables) for 18 AWG wire in certain instances.

LAN Cabling: Going Beyond Standards to Improve Capacity

Blog Category: , , by

Cabling standards exist for a purpose – it assists you get the most out of your networks. Many cabling solutions are designed to execute beyond what the standards specify.

When standards for performance are set by groups like the Telecommunications Industry Association (TIA), the International Organization for Standardization (ISO/IEC) and the Institute of Electrical and Electronics Engineers (IEEE), why go beyond what they advise? Because cable performance which moves beyond standards can lead to a more reliable LAN connection for enterprises.

Bandwidth and Information Capacity

The standards spell out specifications for insertion loss and background noise levels (return loss, near-end crosstalk [NEXT], etc.). If the cable stays within the recommended parameters, the cabling system will function as intended in terms of signal to noise ratio, or information capacity.  For cabling, this is referred to as bandwidth.

From Then to Now (and Beyond): The Advancement of Multimode Optics

Blog Category: , by

Multimode optics, including multimode VCSEL-based transceivers and multimode fiber, has been dominating data center short-reach links. Why? Because they can offer:

  • Lower link costs
  • Less power consumption
  • Higher resistance to fiber misalignment and dirt at connections

There are many innovations in multimode optics on the horizon that will address several challenges, helping support and refine the appeal of multimode optics in the years to come. Let’s discuss them here.

 

VCSEL: The Light Source of Multimode Optics

VCSEL stands for “vertical-cavity surface-emitting laser.” Because of its moderate cost, low power consumption and ability to be manuafactured at high volume in production facilities, it is the light source used for multimode optical transmission.

A VCSEL is typically comprised of 40 to 60 layers of alternating semiconductor materials, each λ/ 4 deep; the bottom and top mirrors of the cavity are made with distributed Bragg reflectors (DBRs).

 

Economic Advantages of Multimode Optics

When measured to singlemode optics, multimode optics continue to be the cost-effective choice for shorter-reach data center applications. The cost of multimode fiber cable is higher than that of singlemode fiber cable, but multimode transceivers are what bring the price down:

How to Earn LEED Materials & Resources Points for Green Buildings

Blog Category: , , , by

LEED (Leadership in Energy and Environmental Design) is an ecology-oriented building certification program run under the auspices of the U.S. Green Building Council (USGBC)

When LEED v4 was launched in 2013, many changes came along with it. One of the major adjustments, in our opinion, has to do with an overhaul of the LEED Materials & Resources credits.

LEED v3 called on project crews to source building products based on a percentage of the total cost of materials that made up the LEED building project. It focused exclusively on single product attributes (such as recycled content) and materials costs.

LEED v4 instead places urgency on the importance of product lifecycle and transparency of product ingredients. LEED Materials & Resources credits now encourage project teams to invest in products and materials that disclose lifecycle information, track environmental impacts of products and reveal the chemical ingredients used in the product. Not only does this switch to the LEED Materials & Resources credits encourage project teams to spend time seeking out environmentally responsible products, but it also benefit manufacturers that produce products with improved (and verified) lifecycle impacts.

 

How to Earn LEED Materials & Resources Points

To gain points in the LEED Materials & Resources category, project teams will need to source 20 qualifying products sourced from five different qualifying manufacturers. These manufacturers, and the products they produce, that have environmental product declarations (EPDs) and either health product declarations (HPDs) or material health assessments (MHAs) can contribute to LEED points.

Even if you’re not currently pursuing a LEED project, paying attention to the building products you use – including cable – offers benefits. Products that can offer LEED Materials & Resources credits ensure that:

  • Products and materials have known hazards revealed
  • Products and materials have undergone processes to document their lifecycle and environmental impacts
