Is Malaysia ready for Cloud?

Posted on March 23rd, 2010 in Virtualization | 4 Comments »

With the current new buzz word in town every IT vendor from network switches, storage, server, software & the list go on and on …….is talking about “Cloud”. It is getting very “cloudy” to me & it seems going to rain.  I just wonder how many of our local ISV know about it & getting their piece of software to ready for cloud.  What about our SME & Enterprise? In January 15, 2010 Gartner conducted a survey

New Virtualization Platform! Cisco Unified Computing?

Posted on March 20th, 2009 in Industry News | 1 Comment »

Just bump into this article about Cisco Unified Computing while reseraching on virtualization. It seems something is brewing in the backyard. Is there going to be another giant releasing something interesting to the market? Take a look at “Introducing Unified Computing to the Data Center”.  I guess this may be the same thing what Craig is referring to “Consolidate Server, Network Virtualization & Storage”.

Virtual Data Center Coming Soon !!!

Posted on September 16th, 2008 in Announcement, Data Center, Industry News | No Comments »

Next generation of Virtual Data Center will be in the roadmap by VMware latest press release.

Here you can have more information about the next generation virtualization.

My personal point of view, this had been something we are looking at for quite sometime. It will be really nice that we could virtualize the data center, with the combination of cloud computing concept cum the virtualize data center together. As more and more application including messaging, ERP, Web hosting are adopting to virtualize, I believe the virtual datacenter will able to simplify and provide better way of managing the next generation enterprise computing.

Storage Planning – Virtualization

Posted on September 10th, 2008 in Data Center, Storage, Virtualization | 1 Comment »

Storage is always the important piece to be run in Data center as well as any solutions we put into the production environment. It will also impact the capacity planning, performance as well as the sustainable period of the specify solution.

Here I would like to specify talk about ESX storage planning. As many of the cases I read and experience before, more and more users are really heading to the stage of choosing specify storage for specify solutions. Example you may think off for using Netapps on NFS for ESX, which claim better performance, dedupe and protocol different. Somehow, the users had forgotten that they had not run any of netapps storage in their existing environment. When we look at the management perspective, the operation management for IT support is not SIMPLIFY. Everyone know how important to standardize our environment as well as simplify out IT environment. The more complex you have, the more pain you will feel.

ESX & VM Networking Concepts

Posted on September 4th, 2008 in Data Center, Virtualization | 4 Comments »

This topic is specifically talk about the networking concept in VM infrastructure. In most of the cases we discuss and Virtualization and Consolidation, we always thought about number of servers we reduce in the data center, the powers we save as well as others facts. Some how, I could see most of the users today who may had already in the production for little while, and will start realize about some performance issues from the network, storage and servers perspective. WIth that particular challenges and reason, we start to hear these groups are trying to tell the customers or users, if you do want to run it on VM, it meant there is performance scarification.

I am strongly disagreed with these comments as most of us know that the reason of consolidate and virtualization, is not for performance reduce, is really to improve efficiency and utilization of the hardware that we purchased. Networking play a big parts in VM infrastructure and most of the time, it did become the performance bottle neck for most users. Let me talk about some example below.

1 of the case i saw here, which the engineer configure it’s ESX in to a server which only have 2 physical NIC connected for VMnetwork interface to allow VM to be connected to the production network. There is more than 10 VMs on the ESX servers which connected to the 2 gigabits NIC and share among each others. In physical environment, for 10 physical servers, they always get 1gb per servers and is not in shared condition. But now, since virtualized, they need to share 2gb with 10 VM. Guess what, the users start complaining slow performance on the network file transfer, the backup through Network is slow as well as any reason that the network slowing down due to the high peak bandwidth utilization from any of the VM which shared on the 2 NICs. Not only the NIC causing the performance issues, and the switches uplink to the DC switches had also another thing you may need to keep an eye on. No matter how many gigabits connection you connected your servers through, it will still depend of the total uplink for your switches to route the traffic to the DC.

In this case, they not really figure out the performance issues as they won’t notice this performance bottleneck in the performance chart from Virtual Center. Most of the time, only the network guys will able to identified these issues. It really hit hard to some of the engineer which push hard on the virtualization, but it did become performance sacrification to the customers at the end. I will not want this to happen for myself, as we had invested SAN storage & High capacity servers which is not cheap solution.
