SANs Demystified
Get up to speed quickly on storage area networks (SANs) in the real world. This detailed resource explains SAN technology and functions, showing how to manage, configure, and build your own SAN for a wide variety of applications.
TABLE OF CONTENTS SANs Demystified
E
- E_Port
- An expansion port on a Fibre Channel switch. E_Ports are used to link multiple Fibre Channel switches together into a fabric.
- EBU
- European Broadcast Union.
- ECC
- Error-correcting code.
- EE_buffer
- A buffer associated with end-to-end flow control.
- EE_credit
- A credit scheme used to manage end-to-end flow control during the exchange of frames between two communicating devices.
- Electronic storage element
- Solid-state disk.
- Embedded controller
- Embedded storage controller, an intelligent storage controller that mounts in a host computer s housing and attaches directly to a host s internal I/O bus. Embedded controllers obviate the need for HBAs and external host I/O buses. Embedded storage controllers differ from HBAs in that they provide functions beyond I/O bus protocol conversion (for example, RAID).
- Encapsulating security payload (ESP)
- A component of IPsec that permits the specification of various confidentiality mechanisms.
- Encoding
- Generation of transmission characters from valid data bytes and special codes.
- Encryption
- The conversion of plain text to encrypted text with the intent that it only be accessible to authorized users who have the appropriate decryption key.
- End of frame (EOF)
- A group of ordered sets that delineates the end of a frame.
- End-to-end encryption
- Encryption of information at its origin and decryption at its intended destination without intermediate decryption.
- End-to-end flow control
- Control of message flow between the two end parties to a communication on a network; flow control that occurs between two connected Fibre Channel N-Ports.
- Enterprise resource management (ERM)
