Storage architecture before cloud migration

With the advent of cloud computing to the gradual acceptance of people, more and more enterprises are scrambling to rush the sweet cakes, the existing IT infrastructure to migrate to the private cloud. The storage architecture, at the heart of the private cloud, is a key element that CIOs and cloud architects need to consider in framing private clouds. Because the consolidation of today's storage architectures and heterogeneous storage environments is limited, businesses cannot install private clouds directly. However, some storage vendors consolidate storage from different vendors to provide a common storage pool for servers, such as EMC, NetApp, and IBM introduced storage virtualization tools (EMC Vplex, NetApp V-series, IBM XIV, etc.).

When it comes to choosing storage consolidation tools for a private cloud, be aware that some storage features are specifically required for storage vendors to be used after storage consolidation. The ability to integrate storage at different locations can also be considered if the data center is in different areas. Storage consolidation tools have a limited number of storage systems to work with, so when you exercise to create a private cloud, you choose an integration tool that meets existing and future requirements.

Scalability based on requirements

Adding any new storage systems to the environment should also be performed in accordance with future storage forecasts without affecting the existing environment. Once the private cloud is created, the storage capacity of the private cloud should be variable and not affect the environment.

Meet the challenge of big data

Data grew exponentially, and "big Data" became a new hot word for it circles. Large data storage management has been the focus of attention because of its high storage requirements and high growth. According to the IDC survey, the number of 2011 data will exceed 1.8 gigabytes (1.8 trillion GB). Many companies envision cloud storage for large data management. When you plan to create a private cloud, you should evaluate these companies if you want to consolidate solutions for large data storage management. Cluster storage systems such as EMC Isilon, NETAPP data ONTAP GX cluster, and IBM Sonas are better for large data storage management because large data grows to a number of petajoules bytes in a filesystem, attached to the rules of private cloud storage, scalability, availability, and flexibility.

Storage Rating

A storage hierarchy is required before creating a private cloud, including the need for existing and future storage in different business applications. For example, ERP applications require FC storage, and HR applications require SATA storage. In storage consolidation, the storage pool should be created from the template. For example, Pool A is SSD storage, Pool B is FC storage, and Pool C is SATA storage. Once you create a private cloud, the future needs to meet storage allocation requirements by using the right pool that depends on the application requirements, so you can maintain consistency and make the allocation easier.

Consolidated Private Cloud Solutions

Many storage vendors offer consolidated private cloud solutions to help you create a private cloud. These solutions include blade servers, FCoE switches, and rack-and-rack storage consolidation. If you want to create a private cloud, these solutions should be considered because they are scalable and rigorously tested. These solutions have a management controller that manages all three components of the cloud-storage, network, and computing. EMC Vblock is one of the solutions.

Future storage requirements

Before creating a private cloud, a plan for the future should not be overlooked, including introducing new hardware for the environment, which should be discussed with storage vendors to incorporate these requirements into the design of the solution.

So you have to remember that it is impossible to make the existing architecture into a private cloud directly, create a private cloud, experience a physical transition to a virtual, and then implement a private cloud. The process of creating a private cloud is therefore segmented.
