It is similar to iSCSI, since it encapsulates an FC frame inside an Ethernet datagram. FCoE is less than 5% of the SAN market place.
iSCSI encapsulates SCSI commands inside an Ethernet frame and then uses an IP Ethernet network for transport. The next largest SAN or block protocol, with approximately 10% to 15% of the market.
Internet Small Computer System Interface (iSCSI). FCP uses Fibre Channel transport protocols with embedded SCSI commands. The most widely used SAN or block protocol, deployed in 70% to 80% of the total SAN market. SAN architectures are ideal for enterprise resource planning and customer resource management workloads. SAP or other large ERP or CRM environments. By centralizing the virtual desktops, organizations can more easily manage data protection and data security. Some VDI environments can easily number in the tens of thousands of virtual desktops. These environments serve virtual desktops to large numbers of an organization’s users. Large virtual desktop infrastructures (VDIs). Virtualized environments concentrate many applications, so infrastructure reliability becomes even more important because a failure can cause multiple application outages. These environments often extend to thousands of virtual machines running a broad range of operating systems and applications, with different performance requirements. Large virtualization deployments using VMware, KVM, or Microsoft Hyper-V. Like Oracle databases, MS SQL Server databases commonly store an enterprise’s most valuable data, so they require the highest performance and availability. These are frequently business-critical and require the highest performance and availability. Storage area networks are frequently deployed in support of business-critical, performance-sensitive applications such as: A well-designed SAN can easily withstand multiple component or device failures. They are designed to remove single points of failure, making SANs highly available and resilient. SANs make up about two-thirds of the total networked storage market. The server partitions and formats those blocks-typically with a file system-so that it can store data on the LUN just as it would on local disk storage. 
A LUN is a range of blocks provisioned from a pool of shared storage and presented to the server as a logical disk. By storing data in centralized shared storage, SANs enable organizations to apply consistent methodologies and tools for security, data protection, and disaster recovery.Ī SAN is block-based storage, leveraging a high-speed architecture that connects servers to their logical disk units (LUNs). A rapidly growing portion of SAN deployments leverages all-flash storage to gain its high performance, consistent low latency, and lower total cost when compared to spinning disk. Storage area networks (SANs) are the most common storage networking architecture used by enterprises for business-critical applications that need to deliver high throughput and low latency.
