There’s even an app for IP exhaustion!

Raj Perumal Raj Perumal Profile: Raj Perumal

Hi folks! So as I previously mentioned in my blogs, the age of IPv4 is quickly dying out. The exhaustion of the address space will probably happen some time in 2012 according to industry experts.

So how does one track this if they have an iPhone? Well of course, there’s an app for that! There’s an app called the IPv4 Exhaustion Counter that shows a countdown of the IP’s as they disappear.

So if you want to morbidly watch the clock tick away, you can download the app here.

Commenting configs

Raj Perumal Raj Perumal Profile: Raj Perumal

Hi folks! So I wanted to rant about one of my pet peeves. That is command line configs and people not commenting them properly!

You see, regardless of what CLI you are using, whether it’s Cisco or HP or some other vendor. Commenting your config so another administrator coming along can understand your thought process is always a helpful thing.

Don’t get me wrong. You can still figure things out without the comments, but if you take the time to do it, you can save an administrator valuable time when they are troubleshooting something in an emergency situation.

This can be just as simple as naming vlans and interfaces so people understand how traffic is flowing on your network when they are looking through the config. It can even help you if you haven’t read your own config for a very long period of time. It can help jog your memory.

So be a friendly administrator and comment those configs!

Battle of the storage!

Raj Perumal Raj Perumal Profile: Raj Perumal

Hi folks! So as you know there was an all out bidding war for 3PAR where HP and Dell were concerned.

Well now Dell has purchased Compellent. How much? Apparently to the tune of $820 million. This was a much cheaper deal than the 3PAR acquisition. The questions is, will they be able to leverage it as good as they could have 3PAR? It’s not secret to anyone that 3PAR was Dell’s first choice.

Compellent has a “compelling” solution, pardon the pun, but 3PAR with their storage offerings and HP backing them, will not take this battle lying down. It should be interesting to see how the storage battle plays out this year.

Storage failure?

Raj Perumal Raj Perumal Profile: Raj Perumal

Hi folks! In the world of storage, there is storage, and then their is redundant storage. The question is, what do you have?

I’ve always advocated purchasing storage that has redundancy built in with a lot of hot swappable parts. Otherwise you are just in for a whole lot of trouble when there is an outage. Also if you need to replace a failed part, does it require downing the system, or can you do it live?

Well HP’s EVA is a great example of a system where you can hot replace parts while the storage is still running. EVA is a great solution for a lot of businesses looking for great uptime. If you have a chance, check out the EVA4400 series, you won’t be dissapointed!

Android Honeycomb

Raj Perumal Raj Perumal Profile: Raj Perumal

Hi folks! If you haven’t heard yet, the Android Honeycomb OS has been announced!

What is this might you ask? It is Google’s answer to the tablet OS. Honeycomb promises to have a great feature set. In this day and age with the iPad here, everyone and their dog wants to have a tablet in their arsenal. I think Google will be a great contender and it should be nice to see what they have to offer.

You can read more about it here and here.

Acer Iconia

Raj Perumal Raj Perumal Profile: Raj Perumal

Hi folks! So at CES this year the Acer Iconia debuted. This is the new dual pane laptop from Acer. The laptop looks like two tablets stuck together.

The question is how usable is this device? Having two screens is great, but at the same time the device seems kind of unwieldy to me. I’m not sure how many people will go for this. On the other hand, hats off to Acer for at least trying something different.

Let’s see how sales unfold for the new Iconia.

SolarWinds Orion Network Configuration Manager

Raj Perumal Raj Perumal Profile: Raj Perumal

Hi folks! So how many of you hate the monotony of performing config backups on large networks with tons of routers and switches? How about making the same change manually to all of them? Not very fun is it?

Well, enter Orion Network Configuration Manager from our friends at SolarWinds. This product allows you to schedule backups of your configs and rollout changes simultaneously to your network devices. Granted, you could script something like this, but SolarWinds puts everything together in a very easy to use nice package.

You can try out a live demo on their site to see what it’s all about too. You can check it out here.

New C series Catalyst switches from Cisco

Raj Perumal Raj Perumal Profile: Raj Perumal

Hi folks! Time to introduce a new line of switches from Cisco, the C series!

Cisco has released their 2960 and 3560 switches in a “C” version. This is their new compact line of switches. These switches are fanless and support POE pass-through.  Cisco describes these switches as switches you would place outside the closet in hard to reach places where you might not even have a power supply available to you. The POE pass-through would power the switch and any POE devices connected to them as long as they are hooked up off of a switch with POE+.

You can read more about the Cisco Catalyst C series here.

Securing use of the iPad

Raj Perumal Raj Perumal Profile: Raj Perumal

Hi folks! So with the release of the iPad, users everywhere are trying to find new and inventive ways to use it in the workplace. The biggest question is the security surrounding it.

Well if one embraces a more non-traditional way of using a tablet device, you can have your cake and eat it too. The iPad is fully compatible with the Citrix Receiver which allows you to securely connect to a Citrix environment.

By setting up your applications this way you can use the iPad securely and not worry about losing any confidential data if the iPad is lost since all the data is on the server side, not the iPad.

Next version of Windows

Raj Perumal Raj Perumal Profile: Raj Perumal

Hi folks! So with Windows 7 being as great as it is, it’s hard to think about what will be in the next one.

Well at CES this year Microsoft announced that the next version of Windows is going to break the mold. How you might ask? Well the next version of Windows is supposed to move past the x86 platform. Microsoft announced that Windows will be available on different platforms.

I can see this as a positive move for Microsoft that will help them proliferate the market even more. It should be interesting to see how this unfolds.
