YouTube’s position on Flash and HTML5

Raj Perumal Raj Perumal Profile: Raj Perumal

Hi folks, so if you have been following the hoopla, YouTube is the latest to weigh in on the Flash vs HTML5 debate!

They recently announced that even though they acknowledge that HTML5 is a step in the right direction, Flash is still continue to be there.

Now here is the interesting thing, Google owns YouTube and as  you know runs the Android platform. So does this announcement really surprise any of us? Not me. I have to agree with YouTube – Flash is quite entrenched and isn’t going anywhere anytime soon.

I still think Apple should change it’s policy and just allow it’s use already. I guess time will tell who wins that war.

Cisco Tablet?

Raj Perumal Raj Perumal Profile: Raj Perumal

Hi folks, this just in, Cisco is going to make a tablet like the iPad!!!

What the heck is up with that? I expect they are using it to leverage some of their other offerings like webex for example. The word on the street is that it’s going to run on Android. This is going to be an interesting competitor for Apple for sure.

It will be good that a  company like Cisco with the backing that it has will enter this arena of competition. It should at least foster some great advances in tablet computing.

What is this device called? They’re calling it the Cius. You can read more about it here.

Cisco Live!

Raj Perumal Raj Perumal Profile: Raj Perumal

Hi folks, are you at Cisco Live? Cisco Live is Cisco’s once a year conference that they hold that covers all sorts of tracks both managerial and technical.

I was supposed to be there this year but I had a lot on my plate so I decided to hold off until next year. However for those of you that haven’t heard of it, listen up – Cisco Live! is a great place to meet like minded Cisco folks and network with them.

It’s also a great place to do training for the many popular Cisco certifications out there. There are tons of topics on pretty much everything imaginable. Cisco Live! is one of those events you just don’t want to miss. I will plan to go next year so maybe I will see some of you there!

Simplifying your network

Raj Perumal Raj Perumal Profile: Raj Perumal

Hi folks, a lot of the times, techs can get carried away and overcomplicate things by putting every technology under the sun in their network.

It’s easy for techs to get whisked away into the wonderful world of IT and want to implement all the latest technologies that they read about lately. Sometimes, this can cause lots of issues, because if you have someone implementing without a clear vision of where they want their network to go, you can end up with a big mess!

The idea is to take a look at your business needs and see how IT can solve some of those problems. See where you can leverage technology to meet those needs and then create an architecture based on that with an eye to the future for scalability and growth.

The “size” of business…..

Raj Perumal Raj Perumal Profile: Raj Perumal

Hi folks, one of the things I tend to talk to clients about on a regular basis is about the “size” of their business. Some people classify themselves as small, some medium, and some enterprise. This is all good and well, but more often than not, people base this soley on number of employees.

Now this method of measurement can work, but there are often other factors to consider. I have seen very small businesses with enterprise level needs, such as high end disaster recovery solutions with hot sites that are required because the type of data they are working on is time sensitive and needs immediate access 24×7.

Then I have seen large businesses with many employees that are ok if the network is down for a little bit as they have other ways of working.

What I am trying to say here is to not base a client’s requirements based on the number of employees, but base it on their actual IT needs. When you do this, you will end up choosing the right equipment at the right price to solve your IT woes.

Extending your LAN wirelessly

Raj Perumal Raj Perumal Profile: Raj Perumal

Hi everyone, one of the common questions I get is how a business can extend their LAN when they can’t use normal wiring to do so.

This inevitably leads to a discussion about wireless technologies and how this can be implemented. I am a big proponent of using some of Cisco’s and HP’s gear in creating wireless bridges from site to site. Both companies make gear that allow you to bridge one network to another using wireless signal.

The biggest thing to take into account would be whether you have line of sight and what kind of distance you need to shoot the signal over. Also weather plays a big factor. There are a lot of little things you can miss when planning out a wireless bridge solution, so I would recommend consulting with someone who has experience in this regard.

Cisco 8 port switches for the SMB network

Raj Perumal Raj Perumal Profile: Raj Perumal

Hi folks, many times I have gone into a client only to see these tiny bargain basement switches littered all over the network.

I think to myself why? I understand they are cheap, but more often then not they just cause the customer grief. With a lot of these no name brand switches you don’t know what to expect. You can get weird things happening with spanning tree or even switches that can’t forward packets at full rate on all ports at the same time.

In cases like these I like to recommend smaller switches from the Cisco Catalyst line. Cisco makes some nice 8 port 2960 Catalyst switches that are great for these occasions. They come from a company that knows the network and actually function as expected!!!

RIM needs to get rid of BES and find something better

Raj Perumal Raj Perumal Profile: Raj Perumal

Hi folks, as you know I am a big proponent of BlackBerry, but I have to admit less and less these days.

Why is that you may ask? Because of my horrible experiences with BES 5. Realistically I think that RIM just needs to get rid of BES 5 and get something better. They need to go back to what they were doing with BES 4 in terms of ease of use at the very least.

The biggest problem is that the other smart phones don’t require the huge overhead that is BES to operate and BES I know can achieve that with BIS but it’s not the same. They should just make BlackBerries easy to use for syncing like iPhones and then still have BES in the background for those users that need the advanced capabilities that BES provides.

Obviously BES has these extra features that the other players don’t, but in my experience that is a small subset of what is actually needed out there. Why else is iPhone and Android gaining so much traction?

Reach me anywhere numbers – VoIP

Raj Perumal Raj Perumal Profile: Raj Perumal

Hi folks, so in this day and age people are always looking for ways to get a hold of you. There are cell phones, office phones, email, texting etc. etc. etc.

But what is the problem with this? It’s a pain in the butt to call all these different numbers just to get a hold of someone. What’s the solution? Reach me anywhere! Essentially this is where you configure your VoIP system to ring your office line, cell phone and any other phones you have at the same time, or in some pre-programmed order.

This way you only have to give out one phone number and your client can reach you anywhere! This is a common feature today in Unified Communications and something that more people should be implementing. Speak with your VoIP provider and see if they can do this for you!

Fiber channel or iSCSI?

Raj Perumal Raj Perumal Profile: Raj Perumal

Hi folks, so the age old storage question, should i use FC or iSCSI?

Well this isn’t necessarily an easy question to answer. They both have their advantages and disadvantages. Here are my thoughts on the matter.

iSCSI is great for cheap storage, and allows you to get it up and running quickly in your environment, especially if you already have the data switch infrastructure to support it. All you have to do is section off a part of your network for it and you’re good to go. The downside? Your storage network is on your data network. This can cause interesting performance issues if things are configured correctly.

FC is a different story. It has it’s own fabric that is separate from the data network. Because of this the data network doesn’t impede it and it can run happily on it’s own. The downside? FC is usually more expensive and you also have to buy FC switches to accomodate your FC storage. FC is super fast, but at a price.

Generally the farther into the enterprise you roam, the more likely you are to see FC for mission critical apps and data and iSCSI for second tier backups or non-mission critical apps and data. There are exceptions to this however, for example some people will run separate data switches just for iSCSI so the two networks don’t cross.
