Programming Blog Post
Today in class (4/12/12) we discussed temporarily chapter 9. After doing that we spoke on the date we would be having our second exam. If you have yet to study I'd suggest you do so immediatly. Should not be that difficult though. For the rest of the class today we took a Quality Enhancement Plan test.

SearchStorage: Cloud Storage - 5 best practices for moving to cloud.
I recently read an article from SearchStorage.com about the 5 best practices for moving to cloud. I will briefly explain what each practice is.
The first best practice that the article states is to scrutinize service-level agreements. Meaning to closely examine your service-level agreements before committing. Lauren Whitehouse, a senior analyst feels that data access is an area that needs close examination in an SLA.
The second best practice that the article discuss is to Follow your business needs. Businesses can save millions of dollars by creating a private cloud. Business now have an easier way to say consolidation, virtualization, standardization.
The third best practice is to Repurpose your own resources. Alex Godelman, Vice President of technology at Gorilla Nation said that cloud replaced more expensive NAS setup. In order to grow the internal cloud all you have to do is add more nodes.
The fourth practice is to Prepare for the future. The author of the article believes that even if you are not ready for the cloud you should still begin to think about how it can help your business down the road.
The final practice discussed in the article is to Beware of hidden costs. The basic cost per gigabyte of cloud storage will be given to you but the basic costs are only part of the bill. Providers may charge extra for data transfers, metadata functions, or copying and deleting files.

Network/Storage Virtualization.
Virtualization is the engine that runs cloud computing. There are many types of virtualization though. The main types are server, network, and storage.
When dealing with network virtualization many tend to confuse it with VLAN. Network virtualization is far more complex than VLAN alone. With network virtualization you are taking many of the traditional client based services and allowing access to them over a network. Cisco believes that there are 3 parts of network virtualization which are: access-control, path isolation, service edge.
When dealing with storage virtualization many people also get it confused with SAN but as before it is more complex than SAN. Storage virtualization can be seen as an abstraction at a layer in the storage software and hardware stack. Many data centers utilize Storage virtualization to run the cloud technology.

Backup and Recovery
Backup and Recovery is very important in Information Technology. A backup is the process of making copies of data which one may find important and would allow for one to recovery any data that may have loss. A backup strategy begins withe a concept of a data repository. Different repository models have different advantages. The different models include Unstructured, Full only/System Imaging, Incremental, Reverse delta and Continuous Data Protection.
Different companies specialize in created backup and recovery products. EMC being one of them. Their company is said to have reliable, efficient, cost-effective data protection for data centers, remote offices, laptops, and more. Some of their products include Data domain, disk libraries for the mainframe, as well as software such as Avamar and NetWorker.
As long as new data is being created and changes are being made to the data backups will need to be updated. It is important to know the different objectives of the backup process. They include RPO, RTO, and data security. RPO is the recovery point objective which is the point in time that the restarted infratstructure will reflect. RTO is recovery time objective which is the amount of time elapsed between disaster and restoration of business functions.

Field Trip to EMC
On October 28th my Foundation of Storage Technology class took a field trip to the EMC buildings in Durham, NC. We also traveled to there Center of Excellence located in Apex, NC.
When we first got there we were given a tour of the warehouse where they received orders, put the parts with the machines, and ship off their products. A couple of things I found interesting about the facilities were one they had motion-sensor florescent lights installed to preserve energy. Another interesting thing about the facilities was that they have vendors from almost every company that creates storage; companies such as Seagate, Hitachi and Western Digital.. During the tour our guide was explaining to us how all of the boards they create go through many tests. The first test that all boards go through were chambers.
After the tour of the warehouse they Vice President of the company Bob Hawkins came to speak to us about the company more. Come to find out that the vice president of this storage solutions company had a degree in political science. He was very informing though and something he piointed out to the group was that the amount of digital data is doubling every two years. He also felt that North Carolina brings in a lot of data centers because the cost of power is reasonable.
Here are two of the few pictures they allowed me to take at the Center of Excellence.
