Redpine Signals, Inc. IoT Wi-Fi & Bluetooth Power Consumption Redpine Signals vs Cypress Semiconductor, Qualcomm Tech. & Texas Instruments

Document number: 218146
Release Date: 24 Jan 2019

The ever-growing Internet of Things (IoT) relies heavily on battery power. Unlike mobile phones and tablets, IoT devices such as doorbells, smart locks and remote sensors cannot easily be recharged. Other devices like wearables have very small battery sizes imposing tighter power constraints. Thus, prolonging battery life by minimizing power consumption becomes a critical concern in IoT.

Redpine Signals commissioned Tolly to evaluate two of their IoT SoCs, the RS9116 and the RS14100 and compare their power consumption with competing IoT offerings from Cypress Semiconductor, Qualcomm Technologies and Texas Instruments. Tests run in an RF chamber included Wi-Fi and Bluetooth Low Energy (BLE) scenarios and benchmarked power consumption in Wi-Fi Standby Associated Mode, while running a secure TCP stack (with and without co-channel traffic) and in a multi-protocol scenario using BLE.

The power consumption of the Redpine Signals solutions was dramatically lower than the competition in every test scenario.

Extreme Networks Extreme Networks Summit X440 Series Switch Performance, Features and Power Consumption Evaluation

Document number: 212132
Release Date: 01 Oct 2012

Video/voice, database, financial and other applications put increasing bandwidth demands on the network. Even with these ever-increasing demands, it is expected that a networks’ latency remains low. Extreme Networks, Inc. commissioned Tolly to test and verify L2/L3 performance, power consumption, latency and features of their Summit X440 Series switch.

The test results show that a Summit X440 series switch loaded to 100% of capacity will not drop traffic while still maintaining low latency. Thus, the Summit X440 will not compromise overall network performance during periods of high traffic. The Extreme Summit X440 earned 18 Tolly certifications for product functionality in QoS, L3 functionality and other areas, as well as a key differentiator common across all Extreme Networks switches: ID Manager. Power consumption tests proved the Summit X440-48p-10G consumes less than 100W during periods of high network utilization.

Hewlett Packard Enterprise HP 3800 Switch Series Competitive Performance, Power Consumption and TCO Evaluation Versus Cisco Catalyst 3750-X and Juniper EX4200 Series

Document number: 211127
Release Date: 27 Sep 2011

Enterprise-class networks are facing increasing demands for higher port- density and throughput driven by rich media applications like voice and video over IP.. Traditionally, network access layer switches delivered the port- density, fault-tolerance and scalability using either a chassis or a stack of fixed-port switches. Stackable switches, when properly architected, can offer network managers a solution that can be scaled as the needs of the network grow over time. In this report, the HP 3800 series switches were compared against Cisco’s Catalyst 3750-X and Juniper’s EX4200 series switches.

The performance of the HP meshed stacking technology used by the HP 3800 Switch Series was compared against the Cisco Catalyst 3750-X with StackWise Plus technology, and Juniper’s EX4200 switches using the Virtual Chassis stacking technology. Test results show the HP switches deliver significantly higher throughput at lower latency in both a standalone and in a four-switch stack configuration. According to HP, its new switches were designed with a large per-port buffer to deal with bursty traffic, allowing them to handle larger microbursts than the Juniper and Cisco switches.

Rackable Systems, Inc. commissioned The Tolly Group to evaluate the power consumption and power efficiency of its C1001 Eco-Logical™ Server against similarly configured, low power-draw Intel Xeon processor-based 1U rackmount servers from Dell, Hewlett- Packard Co., IBM Corp. and Sun Microsystems, Inc.

The Tolly Group used a highprecision Chroma Model 66202 Power Meter to examine the power consumption of the servers on a 208V, 60Hz feed, at idle and while running the High Performance LinPack benchmark.

Tests also measured the power efficiency of the AC power supply unit from the Rackable Systems C1001 server at the component level. Tests were conducted in March 2008.

Nortel Ethernet Routing Switch 8300 Series Competitive Performance Evaluation versus Cisco Catalyst 4500 Series with Supervisor Engine V-10GE

Document number: 208277
Release Date: 18 Mar 2008

Nortel commissioned The Tolly Group to evaluate the Layer 2 switching performance, resiliency and ease of use delivered by the company’s chassis-based Ethernet Routing Switch (ERS) 8300 which is deployed in enterprise wiring closets, or as an aggregation or a core switch. The Nortel ERS 8300 modules tested include Switch Fabric Modules, plus 24- and 48-port GbE interface modules and a 10GbE module.

Engineers measured the performance, resiliency characteristics and power consumption of the ERS 8300 and a comparable Cisco Catalyst 4500 chassis-based switch with the maximum allowable equivalency in module configuration. Engineers also measured resilient performance between the Nortel ERS 8300 running switch clustering and the Cisco Catalyst 4500 running High Availability (HA) solutions. Tests were conducted in January 2008.

Extreme Networks BlackDiamond 8810 Core Switch “Green” Evaluation of Energy Consumption vs. Cisco Catalyst 6509 and Foundry BigIron RX-16

Document number: 208284
Release Date: 29 Feb 2008

Extreme Networks, Inc. commissioned The Tolly Group to evaluate the power consumption of its BlackDiamond 8810 series switch versus the power consumption of the comparable core switches from Cisco Systems, Inc. and Foundry Networks, Inc.

Tolly Group engineers measured the total watts consumed by the Black- Diamond 8810 switch, a Cisco Catalyst 6509 and a Foundry BigIron RX- 16. Power consumption measurements were taken across more than a dozen traffic load scenarios, ranging from no load on the switch to a heavily taxed load of eight 10GbE ports and 96 Gigabit Ethernet (GbE) ports. Tests were conducted in January 2008.

Nortel Business Ethernet Switch BES50GE-24T PWR SMB Switch Evaluation vs Cisco Catalyst Express 500 and HP ProCurve Switch 2626-PWR

Document number: 208271
Release Date: 27 Feb 2008

Nortel commissioned The Tolly Group to evaluate its SMB-class Gigabit Ethernet LAN switch, the BES50GE, and compare it to similar entry-level “converged” offerings from Cisco Systems, Inc. and HP ProCurve.

The baseline requirement in selecting switches was that each provide highspeed data transfer with Gigabit Ethernet (GbE) and be able to power VoIP phones, security cameras and wireless Access Points (APs) via Power over Ethernet (PoE).

Neither Cisco nor HP offers a switch directly comparable to Nortel which uniquely combines GbE on all ports and PoE on half the ports. Both Cisco and HP offer SMB customers either PoE or GbE — but not both. With PoE a base requirement for convergence, the Fast Ethernet (FE) HP ProCurve 2626-PWR and Cisco Catalyst Express 500-24PC models were chosen. Tests were conducted in January 2008.

Nortel Ethernet Routing Switch 2500 & 4500 Series Evaluation in “Green-IT” environments vs. Cisco Catalyst 3560G/E & 3750G/E Series & HP ProCurve 2600 Series

Document number: 208269
Release Date: 22 Jan 2008

Nortel commissioned The Tolly Group to evaluate the company’s Ethernet Routing Switch (ERS) 4550T-PWR and 4548GT-PWR with Redundant Power Supply 15 (RPS 15), as well as the ERS 2526T-PWR and ERS 2550T-PWR to determine the price per port for delivering PoE, switch power consumption and heat dissipation.

Tolly Group engineers also measured the cost to deliver full PoE (~15.4W) on all ports simultaneously for the Nortel ERS switches tested versus Cisco Catalyst 3560G- 48PS, 3750G-48PS, 3560E-48PD, and 3750E-48PD; and HP ProCurve 2626-PWR and 2650-PWR switches. Tests did not focus on the Cisco 2960 Series and HP ProCurve 2800/2900 Series since PoE was not supported on those devices at test time. Engineers also verified the PoE power management tool of Nortel-only products via CLI, Java Device Manager (JDM) and Web-based management.

Without any external power supply attached to the tested devices, engineers measured the power consumption for a switch at factory default mode to determine how much the national average commercial electric cost over three years of continuous operation. Based on switch power consumption results, engineers calculated associated cooling costs from heat dissipation for all switches tested.

Tests were conducted in October 2007.
