Dedicated block-based storage, leveraging a high-speed architecture that interconnects and delivers shared pools of storage devices to multiple servers. This makes its data act as if it were locally attached.
Storage Area Network (SAN)
Initiator
Internet Small Computer Systems Interface (iSCSI)
Software-Defined Network (SDN)
Target
A server that connects to the shared storage device. They run this software that connects to and communicates with the SAN target.

These are not technically a SAN component
They connect to the SAN using a NIC or a host HBA. AN HBA is a circuit board that is inserted into a computer motherboard like a NIC
Host
Storage
SAN Fabric
These are typically:
Disk arrays, Tape libraries, and Optical jukeboxes
Host
Storage
SAN Fabric
These consist of:
hubs, switches, & network cables

SAN Fabric
This is generally used to identify multiple communication paths between servers and storage devices. Multiple paths create a redundant _____ rather than a single thread. Also, this serves as a reminder that the storage area network is different from the production network.
Fabric
Mesh
Bus
Blanket
A switched ___ SAN uses fiber optic cabling, network adapters, and switches to build the SAN fabric.
Install two ___ HBAs in each server.
Deploy two ___ switches by connecting each server to each ___ switch.
Deploy shared storage devices.
Fibre Channel (FC)
Internet Small Computer Systems Interface (iSCSI)
Fibre Channel over Ethernet (FCoE)
Infiniband
An ___ SAN uses network protocols that encapsulate ___ commands within IP packets and transmit them over a standard ethernet network. To build a redundant ___ SAN:
Install two dedicated ethernet NICs in each server. These NICs have either fiber or twisted pair connections.
Deploy two dedicated ethernet switches by connecting each server to each switch using appropriate cable.
Deploy the shared storage devices.
Fibre Channel (FC)
Internet Small Computer Systems Interface (iSCSI)
Fibre Channel over Ethernet (FCoE)
Infiniband
This was deployed to lower the cost of these solutions.
Like iSCSI, this uses standard ethernet switches and physical connections.
Unlike iSCSI, which can run on slow ethernets, this requires 10 Gb Ethernet.
Fibre Channel (FC)
Internet Small Computer Systems Interface (iSCSI)
Fibre Channel over Ethernet (FCoE)
Infiniband
This was designed for high-performance supercomputers.
It features high throughput and very low latency.
It can be used in a SAN as well as between clustered computers.

Fibre Channel over Ethernet (FCoE)
Infiniband
Several factors may influence the choice of SAN technology. Select all that apply.
Cost
Specialization
Speed
Distance
Time
This layer in which various things reside. One example in this layer is that creates the network map of all the devices in the network. Another example is a load balancer that stops and starts VMs as resource use increases.
Application Layer
Control Layer
Data Link Layer
Infrastructure/Physical Layer
This layer is the brains of a SDN network.
Application Layer
Control Layer
Data Link Layer
Infrastructure/Physical Layer
This layer in which the switches, routers, and other network appliances reside.
Application Layer
Control Layer
Data Link Layer
Infrastructure/Physical Layer
The interface that the administrator uses to configure network devices and monitor performance.
Management plane
Northbound API
Southbound API
The API that connects the control layer and application layer.

Standard VoIP phone is a
These have the look and feel of a traditional phone with a base and a handset.
Are really computers that are built to look and operate like phones.
Are connected to a network, like any other computer.
Can be configured using a web browser connected to the web page interface.
Hard phone
Soft phone
The computer's microphone and speakers act as one of these.
Is a software application that is installed on a computer device like ac omputer or handheld devices.
Allows access to the VoIP server for real time audio communication.
Hard phone
Soft phone
This converts voice and fac calls between PSTN and the IP network in real time.
Generally smaller, less costly, and more specialized than VoIP servers.
VoIP gateways
VoIP Protocols
VoIP codecs
Is a special algorithm that compresses VoIP data to reduce bandwidth consumption.
Compresses the data on the sending end and decompresses the data on the receivning end.
Determines the sound quality of the VoIP call and the amount of bandwidth.
This should be adequate for small organizations.
VoIP gateways
VoIP Protocols
VoIP codecs
VoIP uses these that reside on top of transport layer protocols like TCP, UDP, & SCTP to assemble and distribute data throughout your network. Due to QoS considerations, UDP is the most commonly used.
VoIP gateways
VoIP Protocols
VoIP codecs
can assign priority depending the type of network traffic.
Network devices like switches and routers can examine the type of service bits and precedence bits in the header of an IP packet to determine the type of traffic.
Settings on network devices can be configured to give priority to VoIP traffic.
QoS
Latency
Jitter
How long it takes for a packet of data to get from one point to another.
Too much of these callers talk to each other.
It is most important when a VoIP server is hosted in the cloud because of this.
QoS
Latency
Jitter
is a variation in the delay or latency of received packets.
Variability in this during a call can cause unusual sound effects.
When troubleshooting, check settings.
VoIP endpoints can be configured with jitter buffers.
