Finland's IT Center for Science tests 400G with ADVA FSP 3000 TeraFlex

CSC – IT Center for Science, which operates the Finnish University and Research Network (FUNET), has transported 400 Gbps over its existing long-haul network using the ADVA FSP 3000 TeraFlex.

The trials pave the way for ultra-fast access to Finland’s supercomputers and could offer a major boost to Europe’s research and education community.

ADVA's FSP 3000 TeraFlex enables channels of up to 1200 Gbps for 3x 400GbE services and a total capacity of 3.6 Tbps. Using network telemetry, software-defined fractional QAM modulation and adaptive baud rate capabilities, the solution is able to ensure maximum spectral efficiency at every point in the network. This enables operators to leverage previously unused optical spectrum so that deployed infrastructure can be made to transport far more data. As well as succeeding with 600 Gbps transport over 278km and with 400 Gbps over 2,844km, the trials showed the power of harnessing granular increments with speeds of 300 Gbps over 4,681km.

“These trials demonstrate how the ADVA FSP 3000 TeraFlex™ performs over long-haul distances, and the results were well above our expectations. It was the first time when we really needed a gridless line system to enable a full choice of line speeds and modulations. The powerful performance of TeraFlex™ and its flexibility to tune line speed and modulation, will allow us to optimize spectrum usage and minimize the cost of providing services to our users,” said Jani Myyry, FUNET network, CSC – IT Center for Science. “Our network provides essential connectivity for research and education institutes in Finland and throughout the Nordics. Initially we were aiming for transport based on 100Gbit/s and 200Gbit/s but are now seeing an increasing need for speeds above that, up to use cases requiring a bandwidth of multiple Tbit/s. TeraFlex and our ADVA open line system infrastructure enable us to efficiently scale our network with line speeds of 400Gbit/s and above. The trials show how TeraFlex™ dramatically increases flexibility and efficiency for 100GbE and 400GbE transport over long-haul distances.”

Nutanix sees sales bump from remote work and VDI

Nutanix expects total revenue to be between $312 and $317 million for its fiscal third quarter ended April 30, 2020, up 8% to 10% year-over-year. Total revenue growth rate reflects the top line compression resulting from the company’s ongoing transition to a subscription business model and away from selling hardware. TCV revenue is expected to be between $307 and $312 million, up 16% to 17% year-over-year, in line with prior guidance of $300 to $320 million.

Nutanix has withdrawn its fiscal 2020 guidance and calendar 2021 business model targets due to market uncertainty.

Total Contract Value billings (software and support revenue) is expected to be between $371 and $376 million, up 14% to 16% year-over-year, in line with prior guidance of $365 to $385 million. The growth rates of TCV revenue and TCV billings reflect the top line compression resulting from the company’s ongoing transition to a subscription business model. These results are preliminary and unaudited, and are subject to adjustment during the company’s regular quarterly close process.

“Our business is taking important strides in digital prospecting, virtual selling, and remote work. A new company will emerge from this pandemic, and this quarter is just the beginning of that,” said Dheeraj Pandey, Chairman, Co-Founder and CEO of Nutanix. “The recessionary macro environment makes our subscription transformation and our delightful zero-touch products even more impactful, as we enable our customers to be resilient, prepared, and productive. For example, we’ve seen an emerging tailwind in VDI and DaaS this past quarter. With our FastTrack program, we are doubling down with our channel partners and global system integrators to redefine the future of work. Corporate initiatives around remote work, hands-free IT automation, disaster recovery, and lift-n-shift to public cloud datacenters will be some of the pillars of digital transformation, and we believe we will be at the center of these conversations.”

“Thanks to the dedication, teamwork, and excellent customer service demonstrated by our employees and our partner community, we expect to meet our third quarter guidance for TCV billings and TCV revenue,” said Duston Williams, CFO of Nutanix. “While we have continued to see steady demand for our hybrid cloud solutions, there is a significant level of uncertainty regarding the ongoing impact of COVID-19 on our customers and end markets over the coming quarters. As we said we would in our last earnings call, we have been proactively and prudently managing expenses to help ensure the long-term health of our business during this pandemic. In addition, as a result of these uncertainties we are withdrawing our guidance for fiscal 2020, which we provided on February 26, 2020, as well as our business model targets for calendar 2021, which we discussed during our Investor Day in March 2019 and which included, among other things, a target for achieving $3 billion in TCV billings.”
