How to Use Aisle Containment to Increase Data Center Efficiency

For years, organizations have been using hot-aisle/cold-aisle configurations to manage airflow in the data center, extend the life of equipment and lower cooling costs. In a hot-aisle/cold-aisle layout, the fronts of the server racks face each other and draw in cold air to cool the equipment. The backs of the servers also face each other, so that hot exhaust air is less likely to be drawn into the front of the equipment and cause overheating. The Department of Energy estimates that this configuration reduces fan use by up to 25 percent.

However, a hot-aisle/cold-aisle configuration is not enough to meet today’s demandsBecause space is often at a premium, organizations are packing more and more equipment into their data centers. They are also adopting more high-performance servers to support data analytics, artificial intelligence and other demanding applications. Traditional computer room air conditioning (CRAC) systems can’t keep up with the amount of heat being generated.

One of the most effective way to optimize energy efficiency in the data center is to install an aisle containment system. The hot-aisle/cold-aisle layout remains, but cold air and hot air are isolated by partitioning off each aisle. Aisle containment prevents the mixing of hot and cold air, and dramatically reduces the amount of space that needs to be cooled. Organizations can increase the computing capacity of the data center without the risk of hotspots and overheating.

In-row cooling can boost the efficiency of aisle containment even further. One or more cooling units is placed within the row of cabinets, cooling the space within the aisle containment enclosure rather than the entire room. Cold air is focused on the equipment with minimal loss. CRAC units can be set to a higher temperature for substantial energy savings.

Many data centers were built 20 years ago, and organizations are facing the need to upgrade their air handlers and CRAC units to support growing equipment densities. Organizations can forego those upgrades by installing aisle containment and in-row cooling, potentially saving millions of dollars in capital costs. Aisle containment can also be installed on a project-by-project basis to support high-performance equipment, or used to create data center space in a warehouse or other “whitespace.”

It pays to bring in experts to design your aisle containment system. There are a number of variables, and one small miscalculation can derail the entire project. Rahi Systems partners with Enconnex to deploy aisle containment solutions. The Enconnex team consults with each customer to determine the heat load of the equipment, and the ideal size and placement of cabinets in the aisle. Enconnex then puts together a customized kit that includes the cabinets, roof panels, side doors, and airflow and cable management features.

Enconnex also offers a highly efficient in-row cooling solution, as well as cabinet components, accessories, and power and connectivity solutions. By partnering with Rahi Systems and Enconnex, customers gain a one-stop shop for all of their data center infrastructure needs.

Many organizations are finding that traditional approaches to data center heat management are no longer adequate. Let us show you how aisle containment can optimize cooling efficiency and enable your existing data center to support greater computing capacity.

In May, we added some new features to ARIN Online:

  • Completed a number of infrastructure improvements and performed multiple bug fixes.
  • Made improvements to the combined web search and Whois/RDAP search functions, including:
    • Adding the ability to select entities (such as POCs, Orgs, and Customers) in search results to get entity information.
    • Improving query behavior when a user searches for single-word entity names.
    • Returning nameservers in domain queries.
  • Added Google captcha feature to account creation to provide added security.
  • Created additional messaging to notify users of payment status when using a credit card to pay an invoice in the Payments & Billing page.
  • Resolved issues with screen display and usability on certain mobile devices.
  • Fixed parsing issues with third-party library used by the CIDR calculator.
  • Completed work to transition ARIN systems to a stateless architecture to reduce timeouts for users and lessen downtime required for system maintenance. Note: As part of this change, the server used with some REST calls (that download files using your API key) has changed. ARIN has put redirects in place, but you may need to manually configure your scripts to point to the correct server. Please refer to the following pages for information on how to configure these commands and to obtain the correct sample commands:
    • Downloading Bulk Whois Data
    • Downloading the Report of Resources with No Valid POCs
    • Downloading the Specified Transfer Listing Service (STLS) file

Our Featured Policy Requirement:

AS Numbers (NRPM 5.0)

In our last issue of Bits, we mentioned that you can now transfer ASNs through Inter-RIR resource transfers. We’d like to point out that ARIN also has plenty of ASNs available to be issued to organizations in the ARIN service region. If your organization needs to register a unique ASN to Multi-home with Border Gateway Protocol or will have a unique routing policy, your next step will be to submit your request through your ARIN Online account. Additional information and instructions can be found on our Autonomous System Numbers page.

A Tip from Our Registration Services Department:

ARIN Online user accounts are created so that you can log in to ARIN Online to manage your records, request resources, and use our many other services. Accounts are to be used by individuals and should not be shared. Each individual gains access to records by linking their user account to their Point of Contact (POC) and Organization Identifier (Org ID). Additional information on web accounts, POCs, and Org IDs can be found on the ARIN Account Management page.

Check out these customer and member statistics (as of 31 May 2019):

  • 38,313 total customer organizations, including 6,054 member organizations
  • 384 8.3 Transfers and 58 8.4 Transfers completed YTD 2019
  • 8.4 Transfers completed YTD 2019: 15 to APNIC, 27 to RIPE NCC, 8 from APNIC, 8 from RIPE NCC
  • 59.6% of members have an IPv6 block

Blog Spotlight

Ever wondered how ARIN handles reports of route hijacking? In a recent blog by RSD director John Sweeting, we go over exactly what ARIN’s internal processes are for handling route hijacking reports. This includes investigation, communication, and eventually, resolution of the issue.

Other recent TeamARIN blogs include IPv6 case studies, sponsorship information for our upcoming meetings, economic factors affecting IPv6 deployment, and more.

See you in September!

We’ll see you next quarter. Have a great summer!

ARIN’s RDAP and Whois Services: Getting the Information You Need

How to Use Aisle Containment to Increase Data Center Efficiency 1

You have been using a “Whois” tool for years to look up network-related information at ARIN. (The term “Whois” is a commonly-used term that can have multiple meanings, but we’ve been using it to mean a service ARIN provides for you to get data, such as name and contact information, about people who register a resource like an IP address, ASN, or domain.)

There have been some recent changes at ARIN to our search services, and you might be wondering what tools ARIN now provides to look up public registration data for Internet resources. Here’s a quick primer to let you know about what we offer.

Many of ARIN’s users prefer to use a web-based search tool to get the registration data they need, and we offer two of those: Whois/RDAP and Whois-RWS. These tools are named for their underlying protocols: Registration Data Access Protocol (RDAP) and RESTful Web Service (RWS). This graphic provides a brief overview of the differences between the two:

One of the main benefits of Whois/RDAP is that you can use it to get information about resources managed by all of the other RIRs and domain name registries/registrars that support RDAP—not just those managed by ARIN. (Keep in mind that each RIR and registrar stores data about their resources a little differently, so information retrieved on those resources might vary.) Another RDAP benefit is that it supports “bootstrapping,” which helps your queries get directed to the right place faster. ARIN uses RDAP in its “Combined Search Site or Whois” tool that is located on ARIN web pages, and provides separate RDAP documentation on its site.

ARIN also still provides access to its own registration data using Whois-RWS. Although you can search for information on resources managed by other RIRs, you’ll only receive pointers to those records. You also can’t get domain information from Whois-RWS. We provide Whois-RWS documentation here.

If you’re using scripts or developing applications to get Whois data, both Whois/RDAP and Whois-RWS provide an Application Programming Interface (API) that allows you to build queries to get data directly. We provide more information about those commands for Whois-RWS and RDAP on our site.

For users wanting to use a command-line interface to get Whois data, ARIN provides a traditional Whois service that you can access through a terminal window, and we offer NicInfo, our RDAP client. We provide more information about using the CLI, including some command examples, on our site.

So to summarize: if you want to use a fast web tool that gives results from the most sources, give Whois/RDAP a try! If you’re only looking for ARIN-managed resources, or if you don’t want to change to a new search tool just yet, you can still use Whois-RWS. If you want a bare-bones CLI, we’ve got you covered with our Whois “port 43” service. And if you need to get Whois data programmatically, we suggest trying RDAP so you can search for ARIN and other RIR/registrar resources all from one place.

Need more info? Head here:

  • Using Whois
  • Whois/RDAP
  • Whois-RWS

Still have questions? You can contact us, or sign up for the Technical Discussions mailing list and ask questions of others in the community.

In Data we Trust – Balancing Data Innovation with Data Protection

By Darren Watkins, managing director for VIRTUS Data Centres

When a friend asked a 19-year old Mark Zuckerberg how he’d managed to get more than 4,000 email addresses from fellow students, he responded: “People just submitted it. I don’t know why. They trust me.”

Not a great thing to be quoted saying, especially when there have been numerous data scare stories, with Facebook leading the pack. You may remember last year when Facebook faced unilateral criticism for releasing personal information to powerful analytical engine Cambridge Analytica.

Since this scandal, it’s likely that Zuckerberg regrets his teenage bravado, but in many ways, that throwaway comment is so shocking today because it is reflective of our changing relationship with data.

There has subsequently been a barrage of promises in response – by politicians, especially in Europe, but also by tech executives – who say that they will do their best to tighten up controls over our data and even introduce new laws to punish blatant malpractice. Facebook itself started a bounty program which will rewards people who find cases of data abuse on its platforms.

Beyond the scandals, despite the much-documented sense of wariness towards big data applications and the commercial use of personal data by private companies, there are fundamental changes to business processes that come with data use. As executive awareness in the potential power of data has taken hold, businesses have struggled with how best to organize around data – as an activity, a business function and a capability.

What is clear is that we need to come to terms with the fact that big data is here to stay. It’s too intrinsically woven into the fabric of society to go away – it powers healthcare, travel, shopping and even the way we meet and fall in love – it makes the world go around. The onus is firmly on the companies who deal with data to work to build (or rebuild) public trust. They must demonstrate that the data they rely on to do business, is stored, processed and used appropriately. Only then will consumers realize that the good outweighs the bad.

How to get big data right

So how do firms throw off the shackles of the ever-present scandals and ensure that they’re meeting the public demands for transparency, responsibility and security when it comes to big data?

Many would agree that the companies hit by data breaches or scandals have a big PR job to do to mend tarnished reputations. Apologies must be open and chief execs held accountable. One of the biggest jobs to do is far more fundamental than messaging and PR – and is firmly in the back office of a company. Making sure that big data doesn’t become synonymous with big danger is an operation which starts in the data centre.

The building blocks

The data centre sits at the heart of an organization. You might be forgiven for thinking that the IT department isn’t the natural home of innovation and business leadership as it once was, but the big data revolution can only efficiently be delivered from purpose built, highly efficient data centres. When it comes to data applications, responsible innovation is a commitment to balancing the need to deliver compelling, engaging, products and services, with the need to make sure data is stored, processed, managed and used properly. This process starts way away from the headlines or the CEO statements. Getting the data centre strategy right means that companies have an intelligent and scalable asset that enables choice and growth. But get it wrong, and entire businesses are at risk.

We all know that there’s a lot of data out there; according to IBM, 90 percent of the data in the world today has been created in the last two years. This data comes from everywhere: sensors used to gather shopper information, posts to social media sites, digital pictures and videos, purchase transactions and cell phone GPS signals to name just a few.

What companies want to do with the data is increasingly complex too. Many applications demand real-time or near real-time responses, and information from big data is increasingly used to make vital business decisions. All this means intense pressure on the security, servers, storage and network of any organization – and the impact of these demands is being felt across the entire technological supply chain. IT departments need to deploy more forward-looking capacity management to be able to proactively meet the demands that come with processing, storing and analyzing machine generated data. Indeed, it’s no exaggeration to say that the data centre strategy could be crucial to big data’s ultimate success or failure.

To be successful, companies need to strike a precarious balance between innovation and data protection. At one end of the spectrum, there is distrust of the use of data beyond limited, specifically identified purposes. At the other end, the recognition that data is a valuable asset suggests that its more widespread use could empower innovation and economic opportunity. This is a complex argument, which isn’t likely to be categorically solved anytime soon. But whichever side of the fence you fall on, there is a duty for companies who work with data to manage it appropriately. It is imperative that companies have an infrastructure that anticipates growth in data volumes and expansion of data types as well as developing an institutional culture that fundamentally understands the importance of big data. Personnel at every level must work with a mindset that ensures the entry of complete, accurate and uniform data – essentially good data “hygiene”.

Good data hygiene extends to the organization of data too, encompassing well-defined schemas, an organized data architecture and more. This approach allows companies to perform analytics faster, ensuring the data they’re working with is accurate, current and used appropriately. But of course, data storage, processing and maintenance can be expensive.

The big security challenges

For even the biggest organizations, the cost of having (and maintaining) a wholly owned data centre can be prohibitively high. By choosing colocation, companies are effectively achieving the best of both worlds; renting a small slice of the best uninterruptible power and grid supply, with backup generators, super-efficient cooling, 24/7 security and resilient path multi-fiber connectivity that money can buy that has direct access to public cloud platforms to provide the full array of IT infrastructure, and all for a fraction of the cost of buying and implementing themselves.

Perhaps most crucially, the “buy” option when it comes to data centre strategy addresses reliability and security concerns. These concerns mean that a wholesale move to standard, cloud – where security may not be as advanced – isn’t an option. Instead the savviest organizations are quickly recognizing that deploying a hybrid cloud strategy, within a shared environment means that IT can more easily expand and grow, without compromising security or performance.

Of course, colocation or managed services can help to deal with disaster recovery needs. There’s a growing recognition and acceptance that, wherever your data resides, sooner or later it will be compromised, so it’s important to know how to prepare for the inevitable rather than to try and defend the impossible. When you buy a service from an expert, it’s their business to get you up and running again quickly.

Now is a crucial point in the history of big data and there’s scope to get it very right, or very wrong. Data isn’t a demon – but we need to be mindful of the potential for corruption and risk, as well as the significant benefits. Proper infrastructure and good data management can only help to control the bad and make the good better.

We are only just at the very beginning of this data revolution – we need data in our business and personal lives. But consumer demand drives everything and big data is no different. As the public grows more wary of data breaches, the pressure will (and already has) come to bear on the business community to pay more attention to securing, storing and using data in the right way. Countermeasures that used to be optional are now becoming standard and are putting increased pressure is being put on company’s IT systems and processes. It’s in the data centre where companies can take firm control – avoid the scandals and make sure that innovation is done right.
