When you see the following support topology it is only beginning to doubt the relationship between the Falconstor CDP and the database. So, holding the tangled thought of the day, and finally to help my teacher, he gave me the following explanations:650) this.width=650; "src=" http://s3.51cto.com/wyfs02/M00/4A/07/wKiom1QhcdWg8LnRACO70leYi_0830.jpg "title=" Img_ 201409

With the concept of spa and SPB in Vnx, LUNs are linked to spas and SPB for redundancy.There is no concept of SP in Vmax, only front-end director and Back-end director. They support different protocols, FC, iSCSI, FCoE, depending on configuration, LUNs are attached to two FRONT-FA ports for IO redundancy, LUNs are just a sign that communicates with real disk via Back-end port.Front end director Ports, San,

Conventional Ethernet is lossy in nature, which means that frames might be dropped or lost during transmission.
Converged enhanced Ethernet (CEE), or lossless Ethernet, provides a new specification to the existing Ethernet standard that eliminates the lossy nature of Ethernet. this makes 10 GB Ethernet a viable Storage Networking option, similar to FC

1. Technical backgroundFrom the perspective of storage development, the emergence of external isolated storage is to solve the performance problem of large-capacity data storage, FC (Fibre Channel protocol) becomes the perfect choice at this time. Since then, storage has evolved from the DAS Direct-attached array to the storage network stage, where storage becomes a separate data storage network (for the data itself and its security) after the communi
