Where the Cloud Touches Down: Simplifying Data Center Infrastructure Management

Thursday, July 25, 2013
10:00 AM PT/1:00 PM ET

In most data centers, DCIM rests on a shaky foundation of manual record keeping and scattered documentation. OpManager replaces data center documentation with a single repository for data, QRCodes for asset tracking, accurate 3D mapping of asset locations, and a configuration management database (CMDB). In this webcast, sponsored by ManageEngine, you will see how a real-world datacenter mapping stored in racktables gets imported into OpManager, which then provides a 3D visualization of where assets actually are. You'll also see how the QR Code generator helps you make the link between real assets and the monitoring world, and how the layered CMDB provides a single point of view for all your configuration data.

A Network Computing Webinar:
SDN First Steps

Thursday, August 8, 2013
11:00 AM PT / 2:00 PM ET

This webinar will help attendees understand the overall concept of SDN and its benefits, describe the different conceptual approaches to SDN, and examine the various technologies, both proprietary and open source, that are emerging. It will also help users decide whether SDN makes sense in their environment, and outline the first steps IT can take for testing SDN technologies.

Sevone Speeds Netflow Collection And Reporting

Sevone Inc. has announced an update, Version 4.1,  of its network data flow collection and reporting products. The new version doubles the speed of its Dedicated NetFlow Collector, allowing the collection of 15 million flows per minute and increasing the speed of the reports based on the data from the collectors. The update is intended to make the product more attractive to medium- to large-sized enterprises. The company has also enhanced its FlowFalcon NetFlow reporting engine to generate real-time network-wide reports that use the computing resources of all the NetFlow collectors in parallel. This makes report generation faster and also makes it easier to scale. In addition, the new capability means users are less likely to need additional reporting hardware.

Each Dedicated NetFlow Connector, which is a 2U appliance, can manage up to 1,000 interfaces from hardware vendors such as Cisco and Juniper Networks. Additional collectors can be attached in a peer relationship to handle more than 1,000 interfaces. As an example, a T1 link would typically provide 10 flows per second, but larger carriers may have 10Gb networks, which are 6,000 times faster than a T1. This results in many more conversations. The company's largest customer is Comcast Corp., which has 2.2 million elements in his network.

Sevone now also provides functionality known as Universal Metric to Flow Technology, which makes it easier for organizations to use NetFlow data for rapid traffic analysis. Users can use any of the product's supported monitoring technologies to trigger a workflow, using NetFlow for traffic analysis. For example, users can graph network latency from Cisco's Internet Protocol Service Level Agreements, observe a spike, highlight it and drill down into the network traffic to determine what caused the slow response time.

While there are other network flow collector products in the market, the Sevone devices have the highest capacity, says Jim Frey, research director for Enterprise Management Associates, a Portsmouth, N.H., consultancy. Netflow provides a data source as to how the network is being used, but there is a challenge over time to keep up with increased volumes of traffic. For other systems to handle the same amount of traffic as SevOne, more collectors are required, which increases the cost.

The product comes in five models, with five different models of the Performance Appliance Solution network management appliance: PAS5K, PAS10K, PAS20K, PAS40K, and PAS60K. The 5K manages up to 5,000 Simple Network Management Protocol elements and up to 20 NetFlow interfaces; the 10K manages to up to 10,000, and so on.  Starting price is $25,000.
