Software-defined storage logic 2: Energy-Adaptive Distributed Storage System
This paper [3] proposes a flexible and scalable distributed storage system namedFlexStore. This distributed storage
network file systems are generally used to store shared videos, images, attachments, and other static resource files. Generally, files uploaded by website users are stored in NFS sharing. For example, BBS product images, attachments, and portraits are not stored in NFS sharing, then all the front-end nodes access one of the storage services, especially for small and medium-sized website companies.
NFS Flo
demand for storage is increasing, but the IT budget is not increasing or even decreasing. The solution to this challenge is the new technology that needs to significantly reduce storage management costs, which is the main part of the total cost of storage ownership ).
An effective method to reduce management load is to transfer a level-1

ISCSI Network Storage Service
Iscsi implements network storage. The
layer protocol ing layer, maps application layer protocols such as SCSI and IP addresses. Careful readers may find problems. Why is there an IP protocol? Here is an episode. The FC protocol was originally designed as the backbone network backbone for LAN) to replace the Mbps Ethernet ). Of course, we all know that the Gigabit Ethernet and 10-Gigabit Ethernet technologies are the best.
The LAN Based on Ethernet technology is familiar to everyone. So w
traditional host-based storage architecture has become a new bottleneck and cannot meet the needs of cluster system. Cluster storage systems must address two key issues effectively: (1) Provide shared access data to facilitate cluster application authoring and storage load balancing, and (2) deliver high-performance
We know that NFS is a network file system and plays an important role in network protocols. With the development of network storage. It has made great progress in this area. Here we will introduce the application of nas nfs in VMware. NAS is a simple
the sharing of tape libraries and disk array storage devices, the high availability of data, reducing the loss of downtime, greatly reducing operation and management costs, and improving asset utilization. In short, San is the most advanced storage infrastructure in the e-commerce field. IBM-leading San revolution No vendor can compare the contribution made in the Ne
more than millions of dollars of enterprises suitable for investment CEE and FCoE. These enterprise deployments CEE and FCoE will most likely be used to address the problem of hyper-scale server virtualization and the high I/O density. Large-scale applications of CEE and FCoE will appear in 2012 and beyond.
For large enterprises, the deployment recommendations for CEE and FCoE are as follows:
2009-2011 years: Hyper-scale server virtualization requires higher I/O requirements (CEE and FCOE);

Network storage Background
Linux cluster computing is widely used in the field of high-performance computing (high-energy physics, earth, atmosphere, geology, petroleum, remote sensing, etc.) and massive information service (Google.
In Linux Clusters, not only high-performance processors, networks, but also high-aggregation I/O bandwidth are required. The development status of the I/O subsystem determines t
The Chinese name of the NAS is Network attached storage and is a professional storage technology based on hard disk. It can directly access computer network and provide centralized data access service for clients of various operating systems.

With the advent of the information society, how to make small and medium-sized enterprises users can also invest a small amount of money in the data storage to obtain greater storage space and data management? Networked storage is a better solution, and iSCSI technology is emerging, narrowing the distance between SMEs and sans (
Network in the past few years, the dependence of Chinese enterprises on E-commerce Solutions has mentioned an unprecedented level. Mission-critical business data capacity is also growing proportionally, and businesses must store, network, protect, and manage that data.
