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 (FC)
Internet Small Computer Systems Interface (iSCSI)
Fibre Channel over Ethernet (FCoE)
Infiniband
This was developed to lower the cost of Fibre Channel.
Like iSCSI, it uses standard Ethernet switches and physical connections.
Unlike iSCSI, which can run on slower Ethernets, it requires 10 gigabit ethernet.
Fibre CHannel (FC)
Internet Small Computer Systems Interface (iSCSI)
Fibre Channel over Ethernet (FCoE)
Infiniband
This uses network protocols that encapsulate certain commands within the IP packets and transmit them over a standard Ethernet network. To build redundancy:
Install two dedicated Ethernet NICs in each server.
Deploy two dedicated Ethernet switches by connecting each server to each switch.
Deploy the shared storage devices.
Fibre CHannel (FC)
Internet Small Computer Systems Interface (iSCSI)
Fibre Channel over Ethernet (FCoE)
Infiniband
This uses fiber optic cabling, network adapters, and switches to build the SAN fabric.
To build a redundant version of this:
Install two HBAs in each server.
Deploy two switches by connecting each server to each switch.
Deploy shared devices.
Fibre CHannel (FC)
Internet Small Computer Systems Interface (iSCSI)

Infiniband
This SAN technology:
Cost: Least expensive
Specialization: No specialized hardware
Speed: Limited to Ethernet speeds
Distance: Accommodates longer distances, but introduces latency
Fibre CHannel (FC)
Internet Small Computer Systems Interface (iSCSI)
Fibre Channel over Ethernet (FCoE)
Infiniband
This SAN technology:
Cost: More expensive
Specialization: Requires specialized hardware
Speed: Faster
Distance: Up to 10 km
Fibre CHannel (FC)
Internet Small Computer Systems Interface (iSCSI)
Fibre Channel over Ethernet (FCoE)
Infiniband
This SAN technology:
Cost: Less expensive than FC
Specialization: No specialized hardware, but requires specialized knowledge
Speed: Limited to Ethernet speeds
Distance: Accommodates longer distance, but introduces latency
Fibre CHannel (FC)
Internet Small Computer Systems Interface (iSCSI)
Fibre Channel over Ethernet (FCoE)
Infiniband
This SAN technology:
Cost: Most expensive
Specialization: Requires hardware and knowledge
Speed: Fastest
Distance: Short distances (less than 300 m)
Fibre CHannel (FC)
Internet Small Computer Systems Interface (iSCSI)
Fibre Channel over Ethernet (FCoE)
Infiniband
This moves large amounts of data, enabling this in an iSCSI or FCoE SAN can increase performance of the SAN.

Transfer of responsibility
The heart of any VoIP system. Also known as a VoIP PBX or IP-PBX.
The main role is to provide a switching mechanism to connect internal calls between VoIP clients. It provides many functions such as: call waiting, call transfer, conferencing, & voice mail.
Accounts have usernames and passwords to provide authentication and security.

In VoIP, audio is converted from an analog signal to digital data through a technique called
Sampling
Network latency
Jitter
Unified communications
This is a measure of delay as a packet of data travels from one point to another. Too much of this causes VoIP callers to talk over each other.
Sampling
Network latency
Jitter
Unified communications
This is a variation in the delay or latency of received packets. Latency going up and down during a call can cause unusual sound effects (minor pauses, jumps, choppiness).
