These days, most large companies are becoming increasingly aware of the ecological and economic impact of power consumption. Large power consumers (e.g., companies that use a lot of network equipment) have realized that excess power consumption is not only ecologically undesirable, but it also results in larger energy bills. They also realize that a Switched PDU can provide a powerful tool for both measuring and controlling energy consumption by their network applications.

Most console server products provide the ability to establish a secure connection to a console port on a remote network element. But as handy as this capability is … sometimes it’s not enough. If you’re charged with the responsibility of maintaining communication with remote network elements, it doesn’t take long to discover that sometimes, console port access alone isn’t enough to resurrect a crashed router or a misbehaving firewall. Sometimes, a good, old-fashioned power reboot is the only thing that will get that network element up and running again.
All servers and routers will lock up and cease to function sometimes; even top quality equipment like Cisco routers and switches.
Have you ever been woken up in the middle of night by a call from work, and then had to drive all the way to your office just to unlock or reboot an uncooperative router? Does all work at your office regularly grind to a halt every time a piece of network equipment gets a case of the hiccups? Have you ever watched helplessly as constant “truck rolls” to remote equipment sites gradually eat up your yearly budget and tie up your most valuable employees?
When a piece of LAN/WAN, telecom, or other control equipment has “locked-up” and is no longer responding to normal methods of communication, it is often necessary to perform a cold boot of the equipment. After the power has been cycled on and off, normal communications via the network can resume. This is often difficult when the site in question is either an un-manned site, or when the problem occurs after normal business hours. Even if a reboot needs to take place while personnel are on site, one must still hope that the employee is savvy enough not to reboot the wrong device.
For systems administrators, the ability to perform a power cycle or remote reboot is a means of avoiding potential communication disasters. The solution is a Remote Power Reboot Switch which can be controlled by your systems administrator to ensure correct booting sequences in the event of system failures.
SNMP based control and monitoring of remote network devices is a valuable tool for almost any network administrator. WTI’s Serial Console Servers and Switched PDUs provide full MIB support, allowing you to review status, change configuration parameters, edit user privileges and control operating functions at remote units via SNMP commands.
It can be a real pain in the wallet when single power supply hardware loses voltage and shuts down. It can cost a fortune to replace single cord devices with redundant dual power supplies or worse, to change the backup power configuration for your entire network. An automatic transfer switch can provide automatic power redundancy to your single power supply network equipment without the crazy cost or hassle.
Out high amp C-19 power reboot switch is specifically designed to provide remote power control and management capabilities for blade servers and other high-amp rack mount devices.
There are a number of advantages to selecting blades for the server platform in the data center. Yet, there are many obstacles to fully realizing the benefits of this form factor. In this blog post, IT pro Rick Vanover explains the mini blade alternative.
The blade server is great at face value in that there are additional management tools, a reduced space requirement and cost advantages. Many data centers can’t take advantage of blades due to the initial investment or the thought that the requirements would never populate the blades to the break-even cost point. Frequently, the break-even threshold is about 5 or 6 blades within a chassis.
When selecting a remote management solution for a blade server, it’s extremely important to choose a solution that provides full remote command access and power control capability. The reason for this is simple: a solution that provides both remote console port access and remote power control will allow you to perform most diagnostic, troubleshooting and management functions from a remote location, minimizing the need to travel to the installation site whenever the blade server hiccups or crashes.
Nate Lee is a CCIE who attended his first Cisco Live / Networkers event. Here, he describes his experience and some of the technology that he was most excited to learn more about. For even more details of his trip, see the full post at CCIE Flyer.
I found out from my employer that I would be able to go to the show two weeks beforehand. With the short notice, I wasn’t able to book a room at Mandalay Bay with the rest of the packet jockeys and stayed a few hotels down at Aria. When I arrived in Las Vegas around 11:30 PM Sunday not much was going on. Being a person who has taken (and passed!) 8th grade math, I bypassed the late night slot machine crowd and headed to my room where I spent 20 minutes figuring out the high tech curtain and light controls in the room before going to sleep.
Hohm sounds like a handy tool for those who are trying to cut energy consumption in a residential environment … an outlet metered PDU can be a tremendous help to those who are trying to manage power in a data center.
Microsoft’s Hohm website, an online service designed to make it easier for people to figure out how energy efficient their house is (and how to make it better), has become a great deal more useful with the new addition of real estate data. Now, anyone in the US can enter their ZIP code and get an instant, if approximate, evaluation of their house’s efficiency.
These evaluations use a combination of public housing record information and weather data to come up with a score. More dedicated users can sign in and describe their house’s appliances and construction to get a more detailed assessment of their energy usage, and advice on what changes to make to reduce energy bills.
