Data centers remain crucial to businesses’ survival during the pandemic. As more companies transition into remote work, their use of cloud services has skyrocketed. This rapid adoption wouldn’t be possible without the versatility and provision of data centers. Cloud usage aside, internet traffic has increased as a whole, putting more pressure on data centers. Without a reliable network, much of life in quarantine wouldn’t be possible. If data centers weren’t as robust as they are, this heightened traffic could have meant disaster.
Identifying a new location for a data center is not only a critical decision, it can have extreme consequences for all departments. Having a process in place for the site selection team is imperative for success. The process should be viewed as the foundation of every project and every team will build off it.
Increasing fiber optic port density is a crucial requirement for hyperscale data centers because space is at a premium – yet new traffic creates demands for more fiber ports at a blistering pace. Data center operators often cannot expand floor space in their data centers, so the only answer is to increase port density in the rack.
Exactly how do data center owners and operators manage their cabling when their servers are immersed in liquid coolant?
Immersion cooling manufacturers understand the need for cable management when designing their cooling racks. Because the servers themselves are completely immersed, the cable connections are also made under the surface of the coolant. While the liquid used to cool sensitive IT equipment is non-conductive and non-flammable, it can damage certain types of cabling. Some PVC cable jackets stiffen over time from being immersed in the liquid coolant. Data center operators may choose to continue to use low-cost cabling with PVC jackets, like Ethernet cables, and simply swap them out when they stiffen. Otherwise, it’s best to use cables with synthetic rubber cladding, which the liquid coolant does not affect.
CommScope’s Jim Young explains how data centers are responding to the challenges of densification and campus architecture as we move toward 400G.
NeoPhotonics achieved two milestones using its interoperable pluggable 400ZR coherent modules and its specially designed athermal arrayed waveguide grating (AWG) multiplexers (MUX) and de-multiplexers (DMUX). First, data rate per channel increases from today’s non-interoperable 100Gbps direct-detect transceivers to 400Gbps interoperable coherent 400ZR modules.Second, the current DWDM infrastructure can be increased from 32 channels of 100 GHz-spaced DWDM signals to 64 channels of 75 GHz-spaced DWDM signals.
The move to edge cloud is resulting in a huge proliferation of local data centers. By moving processing power and services closer to the edge of the network, a wealth of new cloud-based applications dependent on low latencies and highly reliable connections emerge. Like their centralized counterparts, edge data centers need high capacity like long-haul transport links, but the networks they’re building are fundamentally different. Instead of a connecting a few distant central data centers, cloud providers are connecting dozens of distributed data centers in a single city in order meet the fast response times and low latencies required of new edge computing services.
The Dell’Oro Group reports that sales of optical transport equipment used for data center interconnect (DCI) increased 13 percent year-over-year in 1Q 2020. The segment is dominated by three vendors, Ciena, Cisco, and Infinera, who have a combined market share of over 70%.
As hybrid digital infrastructures consisting of on-premises and cloud-based systems become more and more common within companies, complexity significantly increases. A professional data center infrastructure management (DCIM) tool should be able to manage not only the data center itself, but also hybrid digital infrastructures in all their complexity. In the future, for example, even proprietary customer systems will have to be supplied with detailed information from the data center to ensure end-to-end processes.
Element Critical has expanded its partnership with Crosslink Fiber, LLC to provide ultra-high bandwidth fiber network services to connect to over 54 data centers in the Silicon Valley and the San Francisco Bay areas of California. The solution provides increased flexibility for those companies who need to access or cannot expand at other data centers.
