Term
|
Definition
| SCSI is a bus - an interface that takes information from one place to another. It uses a controller (host bus adapter) to send and receive data and power to SCSI-enabled devices, like hard drives/printers. The controller can be built into the motherboard or added as a card. |
|

Term
|
Definition
| iSCSI is an Internet Protocol (IP) based networking standard for linking data storage facilities. It carries SCSI commands over IP networks, facilitating data transfers over intranets and helping to manage storage over long distances. |

Definition
| A RAID is a series of hard drives treated as one big drive. These drives can read and write data at the same time, known as striping. The RAID controller determines which drive gets which chunk of data. While that drive writes the data, the controller sends data to or reads it from another drive. |

Term
| Define Fibre Channel Adapters |
|
Definition
Fibre Channel is a high–speed interconnect used in networked storage to connect servers to shared storage devices. Fibre Channel components include HBAs, hubs, switches, cabling, and disks.
The term Fibre Channel refers to both the hardware components and the protocol used for communication between nodes. |

Term
| Define Fibre Channel over Ethernet Adapters |
|
Definition
| FCoE (Fibre Channel over Ethernet) is a storage protocol that enable Fibre Channel communications to run directly over Ethernet. FCoE makes it possible to move Fibre Channel traffic across existing high-speed Ethernet infrastructure and converges storage and IP protocols onto a single cable transport and interface. |

Definition
| Ethernet adapters are not the same thing as network adapters. Ethernet cards a type of network adapter that use Ethernet cables to transfer data. |

Term
| How are storage devices (LUNs) represented to ESXi hosts? |
|
Definition
| As far as ESXi is concerned, a device is a SCSI volume presented to a host |
|
|
Term
| Name the use cases for FCoE? |
|
Definition
* You have existing infrastructure, processes, and tools that are designed for FC, and expect WWN addressing not IP addressing
* Your applications require a lossless, extremely low latency transport network model
* Your datacenter already supports 10Gbit Ethernet
* You want to reduce the footprint inside your hosts and cable count coming out of the hosts |
