The “pay-as-you-go” design can enable enterprise-scale networks to keep pace with advances in wireless technologies – such as 802.11ax (Wi-Fi 6), IoT, and LTE – to accommodate continued multi-gigabit network growth.
Siva Valliappan, VP of wired products of Ruckus Networks, said: “The ever-increasing need for Wi-Fi connectivity is taxing network cores, but the solution to keeping up with the proliferation of devices and advances in wireless technology does not need to be complex or expensive. The Ruckus ICX 7850 switch simplifies multi-gigabit network upgrades and reduces the total cost for enterprises through its ability to scale quickly and linearly to address current and future network demands.”
The switch can scale up to 12 in a stack, which rivals the density of traditional chassis-based data centre and enterprise switches. The hitless stack failover, multi-chassis trunking, and in-service software upgrades reduce downtime significantly. The available SmartZone network controller enables configuration, monitoring, and troubleshooting for the entire Ruckus ICX switch portfolio and wireless access point network. This highly scalable approach is easier to manage with reduced power and cooling requirements and a lower total cost of ownership
Security and Encryption
In 2019, network security at a hardware level is vital, and this switch supports the latest security standards and encryption technologies. ICX switches have been deployed in the U.S. federal government for over two decades, and comply with federal certifications, including FIPS, Common Criteria, CSfC, and JITC. It also supports Media Access Control Security (MACsec), a Layer 2 security technology, based on symmetric cryptographic keys, to provide point-to-point security on Ethernet links between nodes.
Many organisations, particularly school districts with older, existing networks that have OM1 or OM2 fibre optic cables require Long Reach Multimode (LRM) optics to achieve the 10 Gbps connections needed for today’s bandwidth requirements. The ICX 7850 provides investment protection and an upgrade path for customers with older fibre infrastructure by providing support for LRM optics.
The switch is now available globally.
Canon EOS R
DxOMark has published the results of its in-depth analysis of the Canon EOS R mirrorless camera.
Click through to read about how the camera compares to other small-to-medium cameras.
The Canon EOS R is a mid-range model and the company’s first full-frame mirrorless camera. It features the new RF mount, which at 54mm is the same width as the EF mount, but the focal flange distance is reduced from 44mm to just 20mm. This should pave the way to some very high-performance lenses. For its first camera in the system, Canon has opted for a familiar 30.3 megapixel CMOS sensor, paired with a DIGIC 8 processor, which enables a native ISO range of 100-40,000 with expansion to 50-102,400, and continuous shooting at up to 8 fps.
The camera’s CMOS sensor achieves an overall DxOMark score of 89 points, which is 29th place among all small- and medium-format cameras in our database. Its key strength is its low-light ISO (Sports) score of 2742 ISO, where it ranks in 27th place overall and in fifth place among the full-frame Canon cameras we’ve tested. Only 0.2 EV (ISO 2742 vs. 3207) separates the EOS R from the best-performing Canon sensor in the EOS-1D X Mark II. The EOS R’s (Portrait) color depth and (Landscape) dynamic range fall some ways behind the best in class, but as with its low-light ISO capabilities, its results are among the best for a Canon sensor.

With the ever present threat of power outages coupled with skyrocketing electricity bills, organisations across sectors are looking for energy efficient and power-saving computing solutions. As with its sister device, the CloudGate X, this mini computer is capable of running the Linux, Windows 10 and Chrome operating systems. However, the CloudGate Xs utilises the newest generation Intel Gemini Lake CPU – and thereby offers a critical performance increase of 25% over the CloudGate X. With its new, sleek design, this powerful device also benefits from improved heat dissipation.
“The CloudGate Xs is an ideal replacement for most desktop computers, at a fraction of the cost,” explains Xavier Nel, Head of Product at CloudGate. “It also comes in at the same price point as the CloudGate X, making it an extraordinarily accessible – yet sophisticated – computing solution. Simply plug in a screen, keyboard and mouse and you have a mini-PC for business or education use.”
This is an eco-friendly solution. By using less than 10 percent of the electricity a typical desktop requires, this user-friendly device lowers the energy footprint for an organisation considerably. With warnings of a fragile Eskom power station always nearby, embracing power-savvy technology – which translates into low running costs – has become increasingly important.
From a connectivity perspective, the computer has 802.11b/g/n/ac Wi-Fi, Bluetooth 4.2 and 1Gig Ethernet. Despite its sleek form, the device boasts three USB 3.0 ports and several others that include VGA, HDMI, RJ45, one DC 12V 2A power input and one 3.5mm audio port. Users will benefit from 4GB DDR4 High-Speed RAM, 64 GB EMMC Solid-State Storage, and an SD card reader. Moreover, storage capacity can be upgraded with an extra 128GB or 256GB m.2 SSD.
The CloudGate Xs ships with a power adapter, VESA Screen Mount, HDMI cable and instruction booklet. Ranging in cost from between R3 499 and R5 199 (depending on the chosen configuration), the CloudGate Xs delivers on several use cases across industry sectors.
