Storage Future


Few day back, I did attend a VMware Architect bootcamp. I see there is a lot of improvement in term of products. What I see potential might happen in future will be the war between the local storage VS the Storage Area Network.

Microsoft have introduce the concept of JBOD where the flexibility can be achieve without relying on the raid controller. On the small scaled company, they can even plug a USB drive and extend the storage which it is very good. 

What VMware have come out with is VMware vSAN which is part of the VMware vSphere 5.5 kernel. To active it we only need to click enable and press OK. With the click of 2. I think VMware have start notice they can't complicate things, and they should make things more user friendly as ever.

The interest part is the Microsoft approach is more toward on building a high end storage without relying on the SAN, but for VMware approach is the similar concept but they extend this to the physical host, which mean that, they can cluster the disk on the local disk for 3 nodes which is the minimum requirement.

This will mean that the big vendor such as IBM, HP and DELL need to come out with a supported model for vSAN. I am not quite sure what it mean in term of investment, but for sure what I know the scalability and availability can be achieve with a lower cost investment compare to SAN.

They will be a pros and cons on 2 products, as end users we must know that we need to have a different products to accomplish the goal. I am going to build my own LAB soon on this area and see how the things goes. I just upgrade my hard drive to 2 intel SSD 530 120GB running on storage spaces. I be using the disk as iSCSI connect to my second computer that run VMware workstation 10. The reason behind it is because I need to install VMware product such as vSphere, vCenter, vCOP & vSRM. For some reason, I can't be bias to one products only ^^.

Storage Improvement


it's was been a while that I have stop on blogging. I was quite busy with the family especially when you have kid:). Sorry for the waiting.

As all of you know that this year Microsoft have release the R2 version of the windows server 2012, there are plenty of improvement that have been agile into the product it self. One of the 2 important areas that I would like to share with you all will be the following:

Candy Crush Cheat Code

The games of Candy crush have cause a lot of players addicted to it as it was simple to play and it is easy. The most important part is the game is offer as a free software. How does the games works is , each play will need to play against the time or a specific level where the requirement was define.

The sad part is, the game only offer 5 lives and with no special power. If the players would like to have more lives and special power, they will required to purchase it. 

Please take note that, what ever have been shared here, it is the responsibility of the users who edit the application or the phone. The author wont be responsible for the damage that causes by the users it self.

Risk In SSD

My view on SSD
When I first been told that, SSD is fast for performance. I am so tempted to get one without thinking what really are those hardware are made from. To be precise, how many of us really care if it does provide 10x of the performance.

But in long term, that would be a risk too, SSD it is not so solid as it is. Why?. This is because the disk only supported with the number of write per day and it will reach its limit. Not like the conventional disk which are relying on the disk spindle. SSD will just stop working working without any notice.

From the point of security, it is always good to have SSD, as it provide a good performance as well the data that are stored in the disk might not be able to recover. Which I think this is pretty good.

The bad side of the SSD is, the disk can fail without warning. Just imagine that if you are running a tera of data inside the SSD and it fail. You might lost all the data, which I see also part of the security issue because it is impacting the availability.

There is some colleagues of mine that are asking should we change all the SSD and keeping away the traditional disk. Just to be aware that, SSD it is not design to have a proper protection when there is a power failure. I don't have an answer for the question, but however what I think is, we used SSD is to have more IOPS. We could mix the disk to achieved the same performance and reliability.

This is not something new, but if you do have doubt. Do sent me your comment too.

Just to share some updates, I will be starting to blogs more on security areas on storage on the coming month. I am still pending to choose the right SSD for my lab:).

Choosing the right SSD

As I was looking into the type of SSD that I would like to purchase, I did google around and check whether there is any comment of the brands and also the performance. What I see so far, I got the link that show the benchmark on the type of the SSD that you should purchase.

You can refer to the following link for more information, looking at the result, it seem samsung 840 will be a right choice for me.,Prix_fpricex100b200,2791.html
