We cannot run away from migrations. Whether we migrate from

- competitor box to HDS box

- older HDS to newer HDS box

- moving to cloud


Migration is one thankless job. These are some of my experience doing migrations.

  1. No body like you. Very true. Every friday night you are the most sought after person, every monday morning you are the most screwed up person.
  2. You have no family time. This is one general complaint from wife and kids. Every weekend when they need you, you are with the migration. Sometime you doubt whom are you married to?
  3. Any amount of planning will not help. Yes. Migration is a job, where you can plan worksheet after worksheet, send tons of email, use all possible color ballpens and high lighters, yet something gets left out on the day of migration.
  4. The most critical server will be running the most outdated OS and application. I never understand this. Customers will have surely one critical server that will have an outdated AIX or HPUX or Linux, that vendors have long stopped support. The applications will run some version or has some dependency that is atleast 2 decades old. Customer will keep asking for a fool proof plan to get this migrated.
  5. The more experience you have in migrations the more time you take to do the tasks. Best to complete jobs is to have minimum experience guys on the field. These guys are just not scared. Scary right??


I am sure like ghost stories, we all have migration ghost stories. Do share.

The term of tiers in data center must be something that we commonly hear. Well, tier I to tier 4 is actually a standard of methodology used to decide the optimization of data center. You know, if the data center can be optimized well it gives you significant result regarding the internet and computer system in your department.


Functions of the Tiers

In general, the tiering system is really beneficial particularly for measuring certain aspects including the work performance of the data center, investment, and also return of investment, commonly known as well with ROI.


From the four tiers, the fourth one is considered as the strongest and resistant towards trouble and failures. It is reasonable; tier 4 is basically designed and installed for being the host of critical server mission and computer system. It is because the system of data center itself planned and designed by including several systems including the power supply, cooling system, security, storage, and others. That’s why if you are the owner of big company or department with the use of many computers and internet system, tier number four can be the best choice. Meanwhile, tier 1 is better for smaller business and shops.


The Tiering in Data Center

Each tier in data center is available with certain capacity and even facilities. In some countries, there is a standard how much capacity can be used on each tier. Tier 1 guarantees the availability of capacity around 99.671%. Meanwhile, bigger amount than tier 1, tier 2 has 99.971%, includes tier 1 and redundant capacity component. Tier 3 is up to 99.982% which consists of tier 1, tier 2, dual powered devices and some uplinks. The last one means the combination of tier 1, tier 2, tier 3, and all other fault-tolerant components, storage, cooling system, HVAC system, and so forth.

I try to do replace follow storage manual but controller not down.

please suggest.

Being in storage for quite some time, I have noted down a few of my observations on what companies do wrong. Some do it wrong all the time and some do it sometimes. The points are related to Storage.


1. Getting the Wrong People.

  • Getting the wrong people in storage department is happening almost all the time. The storage guys are those who are usually brought in as additional help from the server team. They are told that this is some "extra work" they need to do, and in a few months time they get stuck in this. Their interest is still not here. By the time they realize they are in the thick of storage it is too late. These people eventually leave the company and join back server team some where.
  • Many of the Storage Managers are guys who have no knowledge of storage in the first place. Project Managers are borrowed from elsewhere. They have no idea of how things work, either provisioning, replication, or disaster recovery, and make mistakes after mistakes.
  • No one wants to stay in Storage for long. This is true for people from customer side. Every time you meet a customer, the employee irrespective of his or her years in IT, would not have been more than 5-6 years in storage. The meeting would be taken off course to either vmware or hyperv or openstack etc. I call these people as "Harry Potter". They think magic is the solution.

2. Lack of an Engineering Department.

  • This problem is prevalent at the Customer place. Even large customer think that having an engineering department is an expense. They think getting half baked consultants can solve problems, create best practices, increase productivity. These are the people who buy a wrong technology, employ wrong people, and do it at the wrong time. Some times they are lucky that too many mistakes cancel each other and the solution seems to work. But this happens seldom.
  • Lack of engineering department also means lack of commitment. Customer is not committing on a technology and is just looking for a way out from the current mess.

3. No Internal Research.

  • In my presentation to customers I always see that I am taking to people who have not done their homework. They listen to me with 50% attention, understand 25%, and digest 10%. In a week they have forgotten that and just remember some key words. When you meet them again in a couple of weeks they are on the same level of ignorance.


So what is the solution for all this that the customer is in and who can help. Your comments are welcome. I will post the part 2 of this blog.

Internet of things (IoT) is a network of physical objects and entities ranging from smart phones and washing machines to smart energy grids and embedded sensor systems. Everything with an off and on switch to the internet and the ability to transfer data automatically over the network is part of this cyber space.

By the 2020, it is estimated that some 26 billion devices worldwide will be connected to the internet. This is just one of the figures indicating the strong impact IoT has on how we live and the way we work. With such state of internet affairs, a solid infrastructure and security issues become the prime concern.


A vast virtual realm

With endless opportunities it offers, IoT also faces many companies with many cyber threats they don’t know how to deal with. The shortcomings are obvious, and they threat to make the development of IoT sluggish at best. Many businessmen strive to find not only an online tool solution that is tailored to their specific needs, but also one that doesn’t put them in deep water.

This lively cyber environment allows myriad of people to transfer data without any human interaction, or even the need to turn on the computer. Shared hosting environment of a virtual private server (VPS), for example, provides many benefits and boost the business productivity. But how is it possible to safeguard this complex realm of connected devices and networks?

Privacy is the big issue at a time when online file sharing is effortless. There are reports on police security systems, car washes and smart homes being hacked. Big corporations are throwing money at cyber security like there’s no tomorrow and companies like Kaspersky are sounding alarm bells. But, are these threats a bit overblown? They might be, but that doesn’t mean we shouldn’t take them seriously.

Internet of insecure things


The problem isn’t just in all those insecure devices, but the infrastructure behind it all as well. For example, VPS hosting is flourishing as many people find it difficult and costly to set up and manage their own server. All you need to do is to rent your virtual real estate and upload your files to it. But, that’s when the problems start, and VPS hosting around the world is going through some challenging times.

Thus, it’s best to segment the devices that are part of the IoT into separate networks, and restrict the access. The traffic should be than monitored 24/7 to find suspicious entries. Today we can find numerous VPS hosting services that mimic dedicated servers, but include only a portion of the server, not the whole of it. Hence, this is a convenient solution for those with lower traffic on websites and is way better security-wise.


This security-focused approach often means limiting the amount of data that is gathered and shared via IoT devices. Furthermore, whenever asked to provide a password, you make sure it is a strong one. Also, don’t forget to change default passwords on smart devices, otherwise you are connecting to the server with an insecure gadget.

Keep in mind that, however, that this is only the first line of defense, often insufficient to protect our data. Hence, some robust security measures such as data encryption are advisable. There is no silver bullet for those threats, though, and they are constantly evolving. A pro-active security is a priority when it comes to platforms like VPS, and that’s why it’s also important to update software on regular bases and patch it whenever possible.


Let there be interconnectedness


In the future, everything that can be connected to the internet will be connected to it. The immense ocean of interconnected people and devices is full of deadly thunderstorms and fierce winds. The moment they sense vulnerability, hackers and other digital pirates are attacking without mercy. Sophisticated and advanced security measures are called for, but the cyber attacks are always finding the Achilles’ heel. We probably won’t end in a dystopian future some Hollywood movies depict, but we won’t be taking a walk in the digital park either.
