Detailed explanation of cloud storage Framework Setup Steps

Cloud storage can be roughly divided into two categories: the internal cloud and the external cloud. The external cloud is a cloud service provided by a Third-party service provider. Many of the attributes of an internal cloud are the same as external clouds, but belong to the organization itself and run internally.

in today's challenging business environment, IT specialists need to look at their data centers in a broader perspective than ever before. IT departments, such as networks and storage, that used to be isolated within the organization now have to work more closely together because of the integration. This leads to increased collaboration between IT organizations, which brings great benefits to the IT organization, driving performance improvements and cost reductions.


　　

The
San (storage Area Network) dedicated to storage is not only costly but also functionally simple. As the network speeds up, convergence now faces a greater opportunity because the data center backbone network can now hold storage to create a single data transmission pipeline. With iSCSI (Internet small Computer system interface) or Ethernet Fibre Channel (FCoE), storage cloud on the internal IP network is becoming more and more advantageous in flexibility. Traditional network connections will support existing requirements for IP transmission (such as ISCSI,NFS (Network File system) or CIFS (Common Internet File System), and FCoE).


　　


FCoE is designed to drive Sans to the entire enterprise data center. Many data centers use Ethernet for TCP/IP networks and Fibre Channel for storage area networks (Sans). Through FCoE, Fibre Channel becomes another network protocol running on Ethernet, which is transmitted along with traditional IP transmission. FCoE can run directly on the ethernet of the network protocol stack, while iSCSI is running on top of TCP and IP. Therefore, FCoE cannot be transmitted over the IP layer and will not work on the routed IP network.


　　


The new data Center network transmission will contain multiple protocols, including traditional TCP/IP and now FCoE, while continuing to support traditional outward network transmissions for messaging and data communication.


　　


organizations that are sensitive to storage budgets need to know about the cloud.


　　


Cloud Storage


　　


So, what is cloud storage? The best description of the cloud is a public utility unit. The cloud contains a variety of behind-the-scenes technologies-scalable and redundant servers, controllers, storage, and software-that are readily available and combined to create a storage "cloud."


　　


in this mode, we can get a variety of disk pools from geographically dispersed multiple sites, consolidate them into stored logical partitions, replicate them to other places (locally or offsite), and securely deliver consolidated storage to each team through the global namespace accessible on the network.


　　


These disk pools have a variety of features and features, such as data deduplication, automatic compact configuration, high scalability, data protection, and simple management. These consolidated features, coupled with the high bandwidth of the network, enable cloud storage to become reality today.


　　


while the volume of data continues to grow rapidly, many organizations have a huge challenge to their IT budgets, either flat or falling. They must manage data growth on the one hand and keep costs down on the other. Cloud storage can play a role in this area.


　　


within the company's storage environment, about 60% to 80% of the data can be listed as old or outdated data, which should be stored on layer 3rd to 6th.


　　


1--enterprise class, High speed


　　


2--enterprise class, medium speed


　　


3-Layer--san/nas (Network attached storage) (modular, high-speed)


　　


4-Layer--san/nas (modular, Low-speed)


　　


5-Layer--cas (Content-aware storage) (archiving compliance)


　　


6-Layer--VTL (Virtual tape library)





in most data centers, there are a lot of unstructured and archived data that is ideal for cloud storage.


　　


internal Cloud and external cloud


　　


cloud storage can be divided into two categories: internal cloud and external cloud. The external cloud is a cloud service provided by a Third-party service provider. Many of the attributes of an internal cloud are the same as external clouds, but belong to the organization itself and run internally.


　　


when selecting internal and external clouds, network latency must be considered. The external cloud relies on the internet and is therefore only suitable for 4-6-tier data storage. The internal cloud can be used for storage below Layer 3, depending on the local intranet bandwidth.


　　


scalability is a key indicator of internal cloud storage for most IT organizations. While proponents claim that the cloud is very easy to scale and have almost unlimited growth potential, we need to carefully consider cloud fault tolerance, dynamic expansion, and capacity growth planning. Cloud is not a panacea for data growth, it is a commodity that needs to be managed effectively.


　　


In addition, we need to define and understand key performance metrics before implementing cloud storage. In general, we assume that inactive data does not require as high a level of performance as high-level storage. However, other projects, such as electronic discovery, may require considerable performance for such data. 12 Next Page
