Initiatives For CO2 Emissions Reduction
Established in 2010, Aruba has a corporate goal of reducing CO2 emissions by 20% through a combination of managing facility utilities, alternatives to business travel, and telecommuting. To accomplish this goal Aruba has assessed and reduced the environmental footprint of our facilities and IT infrastructure. Our innovative network rightsizing and telecommuting initiative has had a profound impact in our CO2emissions.
IT Infrastructure & Telecommuting
Aruba has deployed high-speed 802.11n and 802.11ac WLANs for >90% of our 1500+ employees. A single WLAN is configured for data and voice applications for use by all Aruba employees located at our corporate headquarters, remote, branch offices, and home offices. We average roughly 15 users per wireless access point. We also provide this solution to the road warriors in our sales force, all of whom connect to the network while traveling.
Field personnel and traveling employees are provided with Aruba’s Remote Access Point (RAP) technology. RAP is a low-cost solution that combines a wireless access point with VPN security and policy enforcement firewall. RAP does not require any software to be installed on the laptop, PDA, smart phone or other devices with which it is used. RAP is also plug-and play: following initial provisioning by the IT department, no further management or configuration of the RAP is needed. Instead, the employee simply plugs the RAP into a local network (or plugs in a 3G cellular modem) and RAP automatically establishes a secure tunnel with our primary or back-up data center, establishes the corporate SSID, and initiates a secure session for both data and voice (including corporate phone extension calling).
These steps enable Aruba to maintain a very thin wired infrastructure with relatively few data switches. This design reduces data room power consumption, increases operating time from our back-up battery uninterruptible power supply (UPS), and reduces cooling loading on our HVACR system. We are also able to minimize wasted cabling associated with office adds, moves, and changes, e.g., in a recent network change to accommodate new employees we required 10km less Category 6 copper cable than would otherwise have been needed.
From a sustainability perspective, our wireless deployment allows us to minimize the use of PVC, polyethylene, polypropylene, synthetic rubber, MIC, nylon, and phenol formaldehyde cable insulation, cable management/trunking systems, and wiring device accessories.
Overall since 2010, Aruba has reduced the number of closet switches and lowered power and cooling requirements up to 20%. Mobile employees can now connect their laptops to the corporate LAN without local IT assistance, regardless of the county in which they’re operating. This eliminates the need for local IT network administrators to travel to branch offices, thereby further reducing our carbon footprint.
While Aruba continues to implement its “rightsizing the network strategies” utilizing our WLAN technology, we have achieved the following savings:
Green Initiatives In Product Design and Maintenance
Aruba’s hardware products do not employ disposable parts subject to wear.
Software maintenance is accomplished via updates that are centrally managed from an Aruba controller and distributed to access points and controllers over the network. This design minimizes the need for dispatching service technicians, saving considerable time and lowering petrol/diesel consumption.
The upgradable design enables customers to continue using all or part of an Aruba network for a longer period than competing designs that are not upgradable.
Aruba’s AirWave Wireless Management Suite manages products from multiple different wireless vendors, allowing a heterogeneous network to be formed from products that would otherwise have to be discarded.
Company Environmental Management System
Aruba outsources product manufacturing to several manufacturing partners. Each partner’s manufacturing facility is certified to ISO 14001. Aruba works with our partners to:
Aruba does not set environmental performance targets and objectives against which performance is audited. Our partners’ compliance is monitored and audited in compliance with their ISO 14001 certification.
Aruba actively works to decrease the quantity and minimize the environmental impact of its packaging. Our company uses eco-friendly packaging or has a collection and recovery system for our packaging. We employ recycled/recyclable cardboard in product packaging, we use print-on-demand for marketing collateral to eliminate unnecessary waste, and we print our annual report on recycled paper.
Aruba reduces transportation/delivery packaging by consolidating materials into fewer but larger shipment whenever possible. We encourage our customers to recycle used packaging, and we will take back used packaging on request by our customers.
Our products are designed for ease of recycling by allowing them to be disassembled externally. Wherever possible products are designed with only one type of polymer or recyclable plastic blend, and molded/glued-in metal is avoided.

Advice to Management
Don't change anything
I applied online. The process took 2 weeks. I interviewed at Aruba Networks (Roseville, CA) in August 2018.
Initial contact phone screen to verify interest in position. Followed by a technical phone screen with some basic fundamentals including Data structures, basic ASIC design concepts like defining clock skew/slew, chip timing issues, hazards and some simple high-level chip questions. Asked basic verification concepts like BFM's, UVM topology, "When do you know if you're done testing something", coverage, etc.
In person interview was more of the same, but more in-depth questions asked in the phone interview. Needed to draw out some basic (pseudo) code describing some modules/structures etc. Overall very relaxed and positive experience
