Out of Band Management – An Alternative Avenue for Communication with Remote Devices

Tuesday, July 12th, 2011

One of the most difficult aspects of managing remote network devices is the challenge of communicating with remote network elements when normal network communication is either down or unavailable. When a vital network element at a remote equipment rack crashes and takes network communication down with it, sometimes the only means to address the problem is an expensive service call to the remote site in order to deal with the problem in person. In cases like this, an out of band management unit can provide network administrators with a convenient, reliable means to communicate with remote network elements regardless of whether communication via the main network is viable or not.


Criteria to Determine Whether or Not to Back Up a System

Tuesday, September 14th, 2010

This seems like a reasonable approach to back-ups and disaster recovery …

For infrastructure administrators, there is nothing more frustrating than expending precious time and system capacity to round out a data protection strategy for systems that don’t need backing up. IT pro Rick Vanover shares some criteria to help navigate these systems.


Pros and cons of replication and tape for data protection

Friday, May 28th, 2010

Some day soon, tape backups will go the way of the 3.5″ floppy disc …

One of the most responsible points of system administration is being able to recover data. IT pro Rick Vanover mulls the decision of protection exclusively via replication or rely on the venerable tape device for small and medium businesses.


Offloading to tape is a data protection strategy that does its purpose well, but can surely be made better in today’s IT landscape. There are good things about tape, such as its ease of transport, low cost, and the relative safety of accidental deletion. On the other hand, the critiques of tape are in no shortage. Tape can have reliability errors that mysteriously only seem to happen on a restore as well as occasionally falling off of a truck. For the small and medium business, these are important factors as alternatives are limited.


When does a Console Server Save Your Job?

Tuesday, May 11th, 2010

Here’s an interesting email from a WTI customer whose console server literally saved the day …

I’m a manager of a large data center that includes row upon row of equipment racks, all stuffed with devices that control the flow of data for a very large corporation. About a month ago, I decided to take a long needed vacation to Hawaii after installing some new console servers at my data center. It was a good thing that I installed those console severs, because they saved my vacation from being ruined by a minor network snafu.

While enjoying the surf and the sun, I received a frantic call from a colleague at a location six states away from my data center, saying that some of our network switches were down and that management needed them back up as soon as possible. Minutes later, I got a call from my boss saying that he was experiencing some major network problems as a result of this issue and that I need to fix it ASAP.

Thanks to our WTI TSM-40 console server, I was able to go back up to my hotel room and access the network units remotely via my laptop, then enter a few status commands to figure out what the problem was, and quickly fix the problem without missing the evening’s luau. The units were back up and running within seconds, and the crisis was averted. The installation of those console servers quite literally saved my job and my sanity, and let me enjoy the rest of my vacation knowing that if anything else happened, I would not need to jump on a plane to go and fix it. I can now feel safe traveling anywhere in the world knowing that I have remote access to my network switches in my data center through my WTI console servers.
